The Little Ghost Nebula: NGC 6369 in Ophiuchus | European Southern Observatory

The Little Ghost Nebula: NGC 6369 in Ophiuchus | European Southern Observatory

Known as the Little Ghost Nebula, NGC 6369 is a planetary nebula in the constellation Ophiuchus, the serpent-bearer. The nebula is relatively faint with an apparent magnitude of 12.9 and the clear detail of this image shows the power of the Adaptive Optics Facility-equipped MUSE instrument of the Very Large Telescope (VLT). The white dwarf star is clearly visible in the middle of the nebular gas that is expanding out in rings.

The Little Ghost Nebula was discovered by William Herschel in 1784. Round and planet-shaped, the nebula is also relatively faint. The high energy radiation from the central white dwarf star causes the surrounding nebula to emit light. A white dwarf is a dense, Earth-sized stellar remnant formed when a star like the Sun exhausts its nuclear fuel and sheds its outer layers. The nebula's main ring structure is about a light-year across and the glow from ionized oxygen, hydrogen, and nitrogen atoms are colored blue, green, and red respectively.

The Little Ghost Nebula should not be confused with the Ghost Nebula (Sh2-136) or the Ghost Head Nebula (NGC 2080).

Cosmic fireflies: Galaxy Cluster Abell 2163 in Ophiuchus | Hubble Space Telescope

Cosmic fireflies: Galaxy Cluster Abell 2163 in Ophiuchus | Hubble Space Telescope

Galaxies glow like fireflies in this NASA/European Space Agency Hubble Space Telescope image. This flickering swarm of cosmic fireflies is a rich cluster of galaxies called Abell 2163. Abell 2163 is a member of the Abell catalog, an all-sky catalog of over 4,000 galaxy clusters. It is particularly well-studied because the material sitting at its core (its intracluster medium) exhibits exceptional properties, including a large and bright radio halo and extraordinarily high temperatures and x-ray luminosities. It is the hottest cluster in the catalog. Observing massive clusters like Abell 2163 can contribute to the study of dark matter, and provide a new perspective on the distant Universe via phenomena, such as gravitational lensing.

Distance from Earth: 3 billion light years

This image was taken by Hubble’s Advanced Camera for Surveys and Wide-Field Camera 3, partially for an extensive observing program called RELICS. The program was imaging 41 massive galaxy clusters to find the brightest distant galaxies.

The Medusa Nebula: Abell 21 in Gemini | Mayall Telescope

The Medusa Nebula: Abell 21 in Gemini | Mayall Telescope

The Medusa Nebula, known scientifically as Abell 21 and as Sharpless 2-274, is an old planetary nebula about 1,500 light-years away in the constellation Gemini. It is estimated to be over 4 light-years across. 

The Medusa Nebula was originally discovered in 1955 by University of California, Los Angeles astronomer George O. Abell. The central star of this planetary nebula is a PG 1159 star. A PG 1159 star, often also called a pre-degenerate, is a star with a hydrogen-deficient atmosphere that is in transition between being the central star of a planetary nebula and being a hot white dwarf. These stars are hot, with surface temperatures between 75,000 K and 200,000 K. They are characterized by atmospheres with little hydrogen and absorption lines for helium, carbon and oxygen.

This image was taken by the Mayall Telescope's mosaic camera with [OIII] (assigned a blue color) and H-alpha (orange) filters.

Star Cluster NGC 6520 & Nebula Barnard 86 in Sagittarius | Victor Blanco Telescope

Star Cluster NGC 6520 & Nebula Barnard 86 in Sagittarius | Victor Blanco Telescope

An image of the open star cluster NGC 6520 and nearby dust cloud Barnard 86 in the constellation Sagittarius, one of the densest parts of our Galaxy. This cosmic pair is set against millions of glowing stars from the brightest part of the Milky Way—a region so full of stars that barely any dark sky is seen across the picture. The bright young stars of this star cluster probably formed out of gas related to the nearby dust cloud. They stand out in contrast to the background of older stars in the bulge of our Galaxy.

Distance: 6,000 light years

This image was taken by the National Science Foundation's Victor Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory (CTIO) in Chile with B (blue), V (green) , I (orange) and H-alpha (red) filters.

Reflection Nebula IC 348 in Perseus (infrared view) | NASA's Spitzer Space Telescope

Reflection Nebula IC 348 in Perseus (infrared view) | NASA's Spitzer Space Telescope

IC 348 is a star-forming region in the constellation Perseus located about 1,000 light years from the Sun. In regions like IC 348, cold clouds of molecular hydrogen gas collapse to form new stars, creating glowing, sculpted scenes like this one. The star-formation process can create impressively varied objects, from massive stars that expire after only a few million years in core-collapse supernova explosions to the smallest and most common stars that are long lived and produce powerful stellar storms.

NASA's Spitzer Space Telescope, formerly the Space Infrared Telescope Facility (SIRTF), was an infrared space telescope that was active between 2003 and 2020. Spitzer was the third space telescope dedicated to infrared astronomy, following IRAS (1983) and ISO (1995–1998). It was the first spacecraft to use an Earth-trailing orbit, later used by the Kepler planet-finder telescope.

Aurora Borealis: View from Alaska

Aurora Borealis: View from Alaska





Astrophotographer Todd Salat: "Here’s a few aurora shots I harvested in the bright moonlight just before 1am on September 25, 2026, near Delta Junction, Alaska. These lights were so brilliant and fast-moving that I had to dial down the camera exposure to a fraction of a second to freeze the action. Pareidolia is taking shape here and someone mentioned they see a saguaro cactus in the first image, and I keep seeing a cat then a dog in the next two which were photographed only 12 seconds apart. I was racing to keep up because for 20 solid minutes multidimensional auroras were racing across the whole sky and left me breathless! Thank you solar wind stream."

Pareidolia: Dictionaries describe this term as a human tendency to see recognizable shapes in objects or data that are otherwise not familiar to us.

Known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

Alaska is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost state in the United States. It borders the Canadian territory of the Yukon and the province of British Columbia to the east. It shares a western maritime border in the Bering Strait with Russia. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south.

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

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.

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.

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
