Wide-field view: Red Carbon Star U Antliae | Digitized Sky Survey 2

Wide-field view: Red Carbon Star U Antliae | Digitized Sky Survey 2

This image from the Digitized Sky Survey 2 shows the very red carbon star U Antliae and its surroundings. It is located about 900 light years from Earth in the constellation Antlia. Around 2,700 years ago, U Antliae went through a short period of rapid mass loss. During this period of only a few hundred years, the material making up the shell seen in the new ALMA data was ejected at high speed. Examination of this shell in further detail also shows some evidence of thin, wispy clouds known as filamentary substructures.

U Antliae is an extremely red C-type carbon star. Carbon stars are cool, luminous red giants with atmospheres containing more carbon than oxygen, giving them a striking red appearance and a key role in enriching the galaxy with carbon. These stars are further reddened by strong mass loss and dust that forms around the star. U Antliae is calculated to have an effective surface temperature of 2,800 K, although the light that reaches us has an appearance more like that from a black body with a temperature of 2,300 K surrounded by dust at a temperature of 72 K. It emits most of its radiation in the infrared and although it is only about 500 times brighter than the sun at visual wavelengths, its bolometric luminosity is 8,000 times higher than the Sun's. Bolometric luminosity is the total electromagnetic power a star radiates across all wavelengths, expressed in watts. It is a crucial measure of a star's true luminosity, as it accounts for all wavelengths, including gamma rays, x-rays, ultraviolet, visible, infrared, and radio waves.

Earth Views during Boost Maneuver | International Space Station

Earth Views during Boost Maneuver | International Space Station

Expedition 75 flight engineer and NASA astronaut Anil Menon: "Space stations can do gymnastics! Look out the Dragon window and watch us flip direction. In order to boost station, we had to change the direction it was pointing, so NASA engineers flipped it around, and, here, you can see it flipping back. This movie was made from 5500 still images that were taken last night and stitched together. The images were not changed but I did increase and decrease the frame rate to give you a better sense of the movement and Earth."

Northrop Grumman’s Cygnus XL spacecraft fired its thrusters for 18 minutes on September 25, 2026, boosting the International Space Station’s orbit.  

The Cygnus XL’s gimbaled delta velocity engine was used to adjust the space station’s altitude by 1.5 miles at apogee, or highest point of station’s orbit, 0.8 miles at perigee, or lowest point of station’s orbit, placing the station in an orbit of 265.5 x 256.8 miles.  

The Cygnus XL spacecraft, supporting NASA’s Northrop Grumman Commercial Resupply Services 24 mission, arrived at the orbital complex on April 13, delivering more than 11,000 pounds of science and supplies to the space station. Cygnus will remain berthed to space station until October when it will be filled with disposal cargo, unberthed from station, and then harmlessly burn up during its destructive reentry into Earth’s atmosphere. 

This reboost sets up the phasing for NASA’s SpaceX Crew-13 mission slated to launch no earlier than October 1 aboard SpaceX’s Dragon spacecraft on the company’s Falcon 9 rocket from  Cape Canaveral in Florida.

Shenzhou-23 Astronauts Send Mid-Autumn Festival Greetings | China Space Station

Shenzhou-23 Astronauts Send Mid-Autumn Festival Greetings | China Space Station

China's Shenzhou-23 astronauts have sent Mid-Autumn Festival greetings from the Tiangong Space Station, 400 kilometers above Earth. The crew shared messages for their families and the country as they marked the festival in orbit. 

The Mid-Autumn Festival, also known as the Moon Festival or Mooncake Festival, is a harvest festival celebrated in Chinese culture. It occurs on the 15th day of the 8th month of the Chinese lunisolar calendar and can fall between September 7 and October 8 (inclusive) of the Gregorian calendar. On this day, the Chinese believe that the Moon is at its fullest and brightest, coinciding with the time of harvest in the middle of autumn.

The Mid-Autumn Festival is one of the most important holidays and celebrations in Chinese culture. The history of the festival dates back now over 3,000 years. During the festival, lanterns of all sizes and shapes—symbolizing beacons that light the path toward prosperity and good fortune for the people—are carried and displayed. Mooncakes, a rich pastry typically filled with sweet-bean or lotus-seed paste, are eaten during this festival. The Mid-Autumn Festival is based on the legend of Chang'e, the Moon goddess in Chinese mythology.

The three astronauts were launched aboard the Shenzhou-23 spacecraft on May 24 for an extended in-orbit mission.

The Vela Ring Galaxy: A cosmic hit and run | MPG/ESO Telescope

The Vela Ring Galaxy: A cosmic hit and run | MPG/ESO Telescope

This picture shows the Vela ring galaxy, visible as a bright core surrounded by a baby blue halo. This ring galaxy—located in the southern constellation of Antlia (The Pump)—is notable due to its compact core and large circular belt of gas and stars.

It is thought that ring galaxies like this are created when larger galaxies are punctured by a smaller galactic aggressor that passing through the heart of its more sizeable victim, triggers a shock wave that spreads outwards. This pushes gas to the galaxy’s periphery, where it begins to collapse and form new stars. The Vela ring galaxy is unusual in that it actually exhibits at least two rings, suggesting that the collision was not a recent one.

This picture also features a galaxy known as ESO 316-33, seen just above and to the left of the Vela ring galaxy, and a bright star known as HD 88170.

The official emblem for NASA's SpaceX Crew-14 mission to the International Space Station

Four crew members from three space agencies will launch to the International Space Station (ISS) no earlier than spring 2027 for a long-duration science expedition as part of NASA’s SpaceX Crew-14 mission.

NASA astronauts Kayla Barron and Chris Birch will serve as spacecraft commander and pilot, with Japan Aerospace Exploration Agency (JAXA) astronaut Makoto Suwa, and Roscosmos cosmonaut Arutyun Kiviryan of Russia as mission specialists. After docking, Crew-14 will join the space station’s Expedition 75/76.

This mission is the 14th commercial crew rotation with SpaceX under NASA’s Low Earth Orbit Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars and to benefit people on Earth.

This will be Barron’s second flight to the space station. She was selected as a NASA astronaut in 2017. Barron earned a bachelor’s degree in systems engineering from the U.S. Naval Academy in Annapolis, Maryland and a master’s degree in nuclear engineering from the University of Cambridge in England. A commander in the U.S. Navy, Barron earned her submarine warfare officer qualification, deploying three times aboard the USS Maine. She first launched to the space station in 2021 aboard NASA’s SpaceX Crew-3 mission, spending a total of 177 days in space across space station Expeditions 66/67. She completed two spacewalks and served as lead robotics operator for another. Most recently, Barron supported the development of new technologies and operational concepts for NASA’s Artemis program.

Barron's biography: https://www.nasa.gov/humans-in-space/astronauts/kayla-barron/

Selected as a NASA astronaut in 2021, Birch graduated from the University of Arizona in Tucson with degrees in mathematics and biochemistry and molecular biophysics. She earned a doctorate in biological engineering from the Massachusetts Institute of Technology, and later taught bioengineering at the University of California, Riverside, and scientific writing and communication at the California Institute of Technology in Pasadena. Birch competed as a decorated track cyclist on the U.S. National Team and was named to the Olympic Long Team for the 2020 Tokyo Games. She has served as a capsule communicator, supporting crews aboard the space station and during the Artemis II mission. Birch was crew lead for Expedition 72, working with flight control teams to help manage daily operations, and served as a crew representative for NASA’s Orion Program, supporting Artemis II mission development and operations. This will be her first spaceflight.

The Crew-14 mission also is the first spaceflight assignment for Suwa. Before JAXA selected him as an astronaut candidate in 2023, Suwa spent nearly a decade with the World Bank Group. Previously, he served in Rwanda as a Japan Overseas Cooperation Volunteer before joining the United Nations World Meteorological Organization. Suwa holds a doctorate in geosciences from Princeton University and completed basic training to become certified as an astronaut in 2024.

Suwa's biography: https://humans-in-space.jaxa.jp/en/astronaut/suwa-makoto/

This mission will be Kiviryan’s first trip to the space station. He graduated from Saint Petersburg Suvorov Military School in 2010 and later studied at the Baltic State Technical University. He graduated in 2015 as an engineer specializing in rocket science and completed training in the operation of computer-controlled machines. Kiviryan was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

NASA's SpaceX Crew-14 patch is a stellar tapestry of stewardship, continuity, and unity. Curved in the ancient silhouette of the ouroboros, the dragon creates a living cupola, framing the dynamic world below. It symbolizes the continuous passing of the baton between International Space Station (ISS) crews and the unbroken watch stood by the teams below. Divided by the orbital terminator, Earth is revealed in breathtaking contrast: one half rests in darkness, lit by city lights in glowing tribute to human ingenuity; the other basks in sunlight, highlighting Earth's natural beauty. The nations represented by the crew are united on a single canvas: while our origins are distinct, our destination in the cosmos is shared. Cradled within the dragon's protective form rest the Earth, the ISS, and all humanity. We stand the cosmic watch, safeguarding our home planet and each other, as we press ever onward into the infinite frontier.

Fade through of galaxy cluster images | Hubble Space Telescope

This video fades through NASA/European Space Agency Hubble Space Telescope images of six galaxy clusters. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total.

By finding that dark matter interacts even less than we thought, the team have successfully narrowed down the properties of dark matter.

The clusters shown here are, in order of appearance: MACS J0416.1–2403, MACS J0152.5-2852, MACS J0717.5+3745, Abell 370, Abell 2744 and ZwCl 1358+62

Full Dome view: Galaxy Cluster MACS J0717 in Auriga | Hubble Space Telescope

This full dome video shows the galaxy cluster MACSJ0717.5+3745, observed by the NASA/European Space Agency Hubble Space Telescope as part of the Frontier Fields program. Using the effect of gravitational lensing caused by the mass of the cluster, this program allows astronomers to study some of the earliest galaxies in the Universe.

MACS J0717 is located about 5.4 billion light-years away from Earth, in the constellation of Auriga (The Charioteer). It is one of the most complex galaxy clusters known; rather than being a single cluster, it is actually the result of four galaxy clusters colliding.

Due to the huge mass of the cluster it is bending the light of background objects, acting as a magnifying lens. It is one of the most massive galaxy clusters known, and it is also the largest known gravitational lens. Of all of the galaxy clusters known and measured, MACS J0717 lenses the largest area of the sky.

Note: The full dome video display format is designed for projection systems in planetariums.

'Disco Lights' from Distant Galaxy Cluster MACS J0717 in Auriga | Hubble

'Disco Lights' from Distant Galaxy Cluster MACS J0717 in Auriga | Hubble 

One of the Frontier Fields targets is shown in this image: MACS J0717.5+3745, or MACS J0717 for short. MACS J0717 is located about 5.4 billion light-years away from Earth, in the constellation of Auriga (The Charioteer). It is one of the most complex galaxy clusters known; rather than being a single cluster, it is actually the result of four galaxy clusters colliding.

Disco is a genre of dance music and a subculture that emerged in the late 1960s from the United States' urban nightlife scene. Its sound is typified by four-on-the-floor beats, syncopated basslines, string sections, brass and horns, electric pianos, synthesizers, and electric rhythm guitars. 

Disco lights are specialized fixtures that add rhythmic light shows to entertainment venues. They originated in the discotheques of the 1970s and have evolved into a fully-fledged tool in event production. Disco lights are sound-activated, remote-controlled, and can feature effect modes such as strobe, rotating, and color-fade effects

In October 2013 Hubble kicked off the Frontier Fields program, a three-year series of observations aiming to produce the deepest ever views of the Universe. The project’s targets comprise six massive galaxy clusters, enormous collections of hundreds or even thousands of galaxies. These structures are the largest gravitationally-bound objects in the cosmos.

This image is a combination of observations from the NASA/European Space Agency Hubble Space Telescope (showing the galaxies and stars), the NASA Chandra X-ray Observatory (diffuse emission in blue), and the U.S. National Radio Astronomy Observatory (NRAO) Jansky Very Large Array (diffuse emission in pink). The Hubble data were collected as part of the Frontier Fields program mentioned above.

Together, the three datasets produce a unique new view of MACS J0717. The Hubble data reveal galaxies within the cluster and far behind it, and the Chandra observations show bright pockets of scorching gas—heated to millions of degrees. The data collected by the Jansky Very Large Array trace the radio emission within the cluster, enormous shock waves—similar to sonic booms—that were triggered by the violent merger.

ESO 576-69 in Virgo: The messy result of a galactic collision | Hubble

ESO 576-69 in Virgo: The messy result of a galactic collision | Hubble


This image from the NASA/European Space Agency Hubble Space Telescope captures an ongoing cosmic collision between two galaxies—a spiral galaxy is in the process of colliding with a lenticular galaxy. The collision looks almost as if it is popping out of the screen in 3D with parts of the spiral arms clearly embracing the lenticular galaxy’s bulge. A lenticular, meaning "lens-shaped," galaxy occupies an intermediate position between elliptical and spiral galaxies in the Hubble Classification scheme.

The image also reveals further evidence of the collision. There is a bright stream of stars coming out from the merging galaxies, extending out towards the right of the image. The bright spot in the middle of the plume, known as ESO 576-69, is what makes this image unique. This spot is believed to be the nucleus of the former spiral galaxy that was ejected from the system during the collision and is now being shredded by tidal forces to produce the visible stellar stream.

SpaceX Starship Launch Rehearsal: Pre-orbital Flight#14 | Starbase Texas

SpaceX Starship Launch Rehearsal: Pre-orbital Flight#14 | Starbase Texas




SpaceX is preparing to go to orbit with Starship on Test Flight 14.

Follow updates and watch the event here → https://www.spacex.com/launches/starship-flight-14

The upcoming flight is planned to be the first to send Starship into orbit around Earth. Flight tests until this point have intentionally flown passively safe suborbital trajectories to maximize public safety while allowing for maximum learning. By going to orbit, the next phase of developing Starship to be fully and rapidly reusable can begin.

This will also mark the first time we plan to deploy Starlink V3 satellites into the constellation, delivering a payload that will dramatically expand connectivity speeds and reliability around the world.

Starship’s initial orbital mission is expected to fly at an altitude approximately 275 km above Earth and complete approximately six orbits around the planet over the course of a nearly 10-hour flight, with splashdown targeted in the Pacific Ocean to the west of Chile.

A live webcast of the flight will begin about 30 minutes before liftoff. Coverage is planned to continue through splashdown with the potential for hours of live views from Starship as it orbits Earth. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned for updates.

The booster’s primary test objective on Flight 14 will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of Mexico. There have been several modifications to hardware and software to address issues seen on the previous flight.

After stage separation and flip on Flight 13, the Super Heavy booster was able to use all 33 engines on its boostback burn for the first time. In the terminal phase of the burn, the three center engines showed signs of ice clogging that triggered an early end to the maneuver. The booster went on to attempt a landing burn, with 8 of the 13 planned engines reigniting before the booster made a hard splashdown in the Gulf. The Super Heavy on this upcoming flight has hardware modifications to improve filtering to the engines and software changes to enhance relight reliability.

The Starship upper stage’s primary objectives include the first orbital insertion maneuver, the deployment of 26 Starlink V3 satellites, a deorbit burn using a single Raptor engine while in space, and a controlled reentry, descent, and splashdown in the Pacific Ocean. Starship will only execute a burn to enter orbit after the flight control team has ensured there is sufficient redundancy on hardware critical to doing the subsequent deorbit burn at the end of the mission.

Starship will deliver 26 Starlink V3 satellites to orbit for the first time. They aim to greatly expand the network's capacity and user speeds. Each Starlink V3 satellite will add 1 Tbps of capacity to the constellation, for a total of 26 Tbps of capacity added on this mission alone. That’s ~10x the capacity compared to a single launch of V2 mini Starlink satellites on Falcon 9.

After deploying from Starship, the Starlink V3 satellites will unfold their antennas and deploy their solar arrays and make initial contact with the ground and the rest of the Starlink constellation via radio frequency and laser links. The satellites will then begin raising their orbits with their onboard thrusters. Following their on-orbit checkouts, the satellites should begin serving customers as soon as a few weeks after launch.

Three of the satellites have been modified with a suite of cameras to scan Starship’s heatshield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heatshield readiness for return to launch site on future missions.

Several upgrades and experiments related to Starship’s heatshield will also be tested, with some improvements derived directly from data gathered from the Flight 13 Starship as it floated in the Indian Ocean. They include additional retention mechanisms added to tiles in areas deemed to be at highest risk of falling off during ascent, addressing recently discovered areas that offer flow paths behind tiles for plasma, and flying multiple areas with a curved tile design that has shown the ability to reduce heating in the gaps between tiles. And finally, two tiles recovered from Ship 40 are planned to be reflown on Ship 41, marking the first tile reuse for Starship.

NASA plans to use a lunar lander version of Starship to deliver astronauts and cargo to the Moon during the Artemis IV mission and beyond through the Human Landing System (HLS) Program.

This will also mark the first time we plan to deploy Starlink V3 satellites into the constellation, delivering a payload that will dramatically expand connectivity speeds and reliability around the world.

Starship’s initial orbital mission is expected to fly at an altitude approximately 275 km above Earth and complete approximately six orbits around the planet over the course of a nearly 10-hour flight, with splashdown targeted in the Pacific Ocean to the west of Chile.

A live webcast of the flight will begin about 30 minutes before liftoff. Coverage is planned to continue through splashdown with the potential for hours of live views from Starship as it orbits Earth. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned for updates.

The booster’s primary test objective on Flight 14 will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of Mexico. There have been several modifications to hardware and software to address issues seen on the previous flight.

After stage separation and flip on Flight 13, the Super Heavy booster was able to use all 33 engines on its boostback burn for the first time. In the terminal phase of the burn, the three center engines showed signs of ice clogging that triggered an early end to the maneuver. The booster went on to attempt a landing burn, with 8 of the 13 planned engines reigniting before the booster made a hard splashdown in the Gulf. The Super Heavy on this upcoming flight has hardware modifications to improve filtering to the engines and software changes to enhance relight reliability.

The Starship upper stage’s primary objectives include the first orbital insertion maneuver, the deployment of 26 Starlink V3 satellites, a deorbit burn using a single Raptor engine while in space, and a controlled reentry, descent, and splashdown in the Pacific Ocean. Starship will only execute a burn to enter orbit after the flight control team has ensured there is sufficient redundancy on hardware critical to doing the subsequent deorbit burn at the end of the mission.

Starship will deliver 26 Starlink V3 satellites to orbit for the first time. They aim to greatly expand the network's capacity and user speeds. Each Starlink V3 satellite will add 1 Tbps of capacity to the constellation, for a total of 26 Tbps of capacity added on this mission alone. That’s ~10x the capacity compared to a single launch of V2 mini Starlink satellites on Falcon 9.

After deploying from Starship, the Starlink V3 satellites will unfold their antennas and deploy their solar arrays and make initial contact with the ground and the rest of the Starlink constellation via radio frequency and laser links. The satellites will then begin raising their orbits with their onboard thrusters. Following their on-orbit checkouts, the satellites should begin serving customers as soon as a few weeks after launch.

Three of the satellites have been modified with a suite of cameras to scan Starship’s heatshield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heatshield readiness for return to launch site on future missions.

Several upgrades and experiments related to Starship’s heatshield will also be tested, with some improvements derived directly from data gathered from the Flight 13 Starship as it floated in the Indian Ocean. They include additional retention mechanisms added to tiles in areas deemed to be at highest risk of falling off during ascent, addressing recently discovered areas that offer flow paths behind tiles for plasma, and flying multiple areas with a curved tile design that has shown the ability to reduce heating in the gaps between tiles. And finally, two tiles recovered from Ship 40 are planned to be reflown on Ship 41, marking the first tile reuse for Starship.

NASA plans to use a lunar lander version of Starship to deliver astronauts and cargo to the Moon during the Artemis IV mission and beyond through the Human Landing System (HLS) Program.

The Remnants of Five Supernovae in Auriga

The Remnants of Five Supernovae in Auriga

The 'ghosts' of five supernovas haunt this extraordinary image. It was acquired at Oukaïmeden Observatory in Morocco with approximately 200 hours of observations and shows a large patch of the sky, equivalent to the area of one thousand full moons tiled together, in the constellation of Auriga (the Charioteer). From left to right, the five supernova remnants visible across the field are G181.1+9.5, G182.4+4.3, G179.0+2.6, G180.0−1.7 (Sh2-240, the Spaghetti Nebula), and G178.2−4.2. 

As each explosion expanded into space, it created a growing shell of shocked gas and delicate filamentary structures shown in red (hydrogen) and blue (oxygen), respectively. These ancient stellar explosions happened independently. They are at a range of distances up to about several thousands of light-years away from Earth and have estimated ages up to tens of thousands of years old. Early humans may have witnessed them as bright new stars, fading over weeks or months.
