Comet C/2025 A6 Lemmon & Aurora Borealis: View from Alaska

Comet C/2025 A6 Lemmon & Aurora Borealis: View from Alaska

Astrophotographer Todd Salat: "Comet Lemmon rises through the aurora glow in the northeast from Trapper Creek, Alaska, a little after 6 am on October 21, 2025. During today’s closest approach to Earth, the comet is star trekking through the constellation Boötes 'The Herdsman,' which includes Arcturus, the bright star near the bottom of this image."

Comet Lemmon is brightening and moving into morning northern skies as it enters the inner solar system where the Sun increasingly makes its ion tail highly active. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year. Comet Lemmon will round the Sun on November 8, 2025. It passed nearest to the Earth—about half of the Earth-Sun distance—on October 21.

Earth auroras have different names depending on the pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

Wide-field View: Trumpler 14 Open Star Cluster in The Carina Nebula | ESO

This image of the Carina Nebula shows the position of the Trumpler 14 open cluster of stars. About 2,000 stars have been identified in Trumpler 14. It is one of the youngest known star clusters, estimates range from 300 to 500 thousand years old. Due to its location within the inner parts of the Carina Nebula, Trumpler 14 is currently undergoing massive star formation.

Distance from Earth:  9,000 light-years

A color-composite image of the Carina Nebula, revealing exquisite details in the stars and dust of the region made with the 2.2-meter MPG/ESO telescope at the La Silla Observatory in Chile. Several well known astronomical objects can be seen in this wide field image—to the bottom left of the image is one of the most impressive binary stars in the Universe, Eta Carinae, with the famous Keyhole Nebula just adjacent to the star. The collection of very bright, young stars above and to the right of Eta Carinae is the open star cluster Trumpler 14. A second open star cluster, Collinder 228 is also seen in the image, just below Eta Carinae. The Carina Nebula also bears the NGC 3372 designation. 

On this image, North is up and East is to the left. The field of view is 0.55 x 0.55 degrees, covering a 72 x 72 light-year region at the distance of the nebula.

Young Stars of Open Cluster Trumpler 14 in Carina | Hubble


Image Processor Judy Schmidt: "This is a very young star cluster located within the Carina Nebula. These are newly formed stars and we are peering at them through a reddening nebula of dust and gas. The longpass near-infrared filter cuts through much of the nebula and reveals many apparently dimmer stars as reddish pinpricks of light. I have adjusted the colors so that the brighter, whiter stars and their surroundings appear bluer because this is a young cluster. In reality, they are at least a little reddened. There is an interesting arc of cloud at the bottom edge of the frame. "

Distance from Earth:  9,000 light-years

Trumpler 14 (Tr 14) is an open cluster with a diameter of six light-years located within the inner regions of the Carina Nebula. About 2,000 stars have been identified in Trumpler 14. It is one of the youngest known star clusters, estimates range from 300 to 500 thousand years old. For comparison, the massive super star cluster R136 is about 1 to 2 million years old, and the famous Pleiades is about 115 million years old.

Due to its location within the inner parts of the Carina Nebula, Trumpler 14 is currently undergoing massive star formation.

China Landspace Reusable Zhuque-3 Commercial Rocket: A Closer Look Pre-flight

China Landspace Reusable Zhuque-3 Commercial Rocket: A Closer Look Pre-flight


Preparation for the maiden flight of China's reusable rocket Zhuque-3 has entered a critical phase after the completion of joint fueling drills and static ignition tests from October 18 to 20, 2025. The successful tests also laid the groundwork for the rocket's official launch and first-stage recovery later this year.

With a diameter of 4.5 meters and a total length of around 66 meters, the Zhuque-3 rocket can carry up to 18 satellites per launch, making it an ideal choice for launching satellites for large-scale constellation networks.

Equipped with landing legs and grid fins for controlled descent, the rocket is designed to vertically recover its most expensive component—the first stage, accounting for 70 percent of the rocket's total cost.

As its first stage is designed to be reused at least 20 times, the rocket has the potential to reduce launch costs by 80 to 90 percent compared with single-use rockets.

Powered by a parallel cluster of nine liquid oxygen-methane engines, the first-stage can achieve meter-level landing precision, as five of the engines are capable of gimballing.

In addition, these engines produce a combined thrust of more than 7,500 kilonewtons, setting a new record for Chinese commercial liquid-fueled rockets.

Beijing-based LandSpace is a leading Chinese private space company. With its Zhuque-2 rocket, LandSpace became the world's first company to launch a methane-liquid oxygen rocket to Earth orbit in July 2023, ahead of U.S. rivals, including Elon Musk's SpaceX and Jeff Bezos' Blue Origin.

The successful Zhuque-3 development marks a significant stride in the pursuit of low-cost, high-frequency, and large-capacity space launches for China's private space industry.

The Jiuquan Satellite Launch Center (JSLC) was founded in 1958. It was the first of China's four spaceports. The launch center has been the focus of many of China's historic space ventures, including the country's first satellite Dong Fang Hong I in 1970 and their first crewed space mission, Shenzhou V, on October 15, 2003. JSLC is now a home for many new Chinese commercial space launch firms, like Landspace.

Mars: A Light-Toned Deposit in Arsinoes Chaos | NASA Mars Reconnaissance Orbiter

Mars: A Light-Toned Deposit in Arsinoes Chaos | NASA Mars Reconnaissance Orbiter

The objective of this observation is to examine a light-toned deposit in a region of chaos terrain. The deposit displays a rough surface, in contrast to the smoothness of the surounding area. Parts of the surface appear as if they were eroded by a fluid flowing north and south. This deposit may have formed in an ancient lake.

Arsinoes Chaos is a chaos terrain in the Margaritifer Sinus quadrangle on Mars. This region of Mars is famous because NASA's Opportunity Rover landed there on January 25, 2004. Arsinoes Chaos is 200 kilometers in diameter. Its location is 7.66 °S and 27.9 °W. Arsinoes Chaos was named after Arsinoe, a queen of ancient Egypt, daughter of Ptolemy and Berenice.

Buttes and mesas in Arsinoes display layering. Many places on Mars show rocks arranged in layers that can form in a variety of ways. Volcanoes, wind, or water can produce them. Of course, layers can be hardened by the action of groundwater. Martian ground water probably moved hundreds of kilometers, and in the process it dissolved many minerals from the rock it passed through. When ground water surfaces in low areas containing sediments, water evaporates in the thin atmosphere and leaves behind minerals as deposits and/or cementing agents. Consequently, layers of dust could not later easily erode away since they were cemented together. On Earth, mineral-rich waters often evaporate forming large deposits of various types of salts and other minerals.

This HiRISE enhanced color camera image (less than 1 km in size) was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 269 kilometers (167 miles).

The University of Arizona, in Tucson, operates the High Resolution Imaging Science Experiment (HiRISE). It was built by BAE Systems in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate (SMD), Washington.

Cosmic Reef: Nebulas NGC 2014 & NGC 2020 in Large Magellanic Cloud Galaxy

Cosmic Reef: Nebulas NGC 2014 & NGC 2020 in Large Magellanic Cloud Galaxy

This science visualization presents the dramatic landscape of two nebulas in the Large Magellanic Cloud about 163,000 light-years away from Earth. The video, based on images by NASA's Hubble Space Telescope, takes viewers on a close-up tour of the nebulas' three-dimensional structures, as envisioned by scientists and artists.

The video begins with the Hubble view of NGC 2014 (lower left) and NGC 2020 (upper right) in the constellation Dorado. The region has been nicknamed the "Cosmic Reef," because of its resemblance to an undersea world. The camera then flies past myriad stars for a close-up look at NGC 2014. The first stop is the bubble of hot gas on the left that has a coral-like appearance. Energetic ultraviolet light from the system's most massive stars has heated the gas, while strong stellar winds (streams of charged particles) help create its bubble structure.

The journey continues into the heart of the nebula, home to extraordinarily massive and bright stars. The glowing gas in this region is bathed in the stars' intense luminosity. In contrast, the dark, denser gas is resisting that radiation, and is blown back to form craggy, mountainous shapes. The virtual flight moves past ridges, valleys, and pockets of new star formation.

The camera then rises up and over a ridge of NGC 2014, revealing the three-dimensional structure of neighboring NGC 2020. The Wolf-Rayet star at its core is the mammoth, intensely hot source of this nebula. Episodes of outbursts from the young star have produced cloudy rings and clumps in the bright blue gas. While Hubble views NGC 2020 looking down the axis of the stellar outflows, the visualization finishes with a side view that illustrates the nebula's double-lobed structure.

Turning American Radio Astronomy into Art | The Very Large Array (VLA)

The United States National Science Foundation (NSF) Very Large Array (VLA) is a powerful radio telescope in New Mexico composed of 27 movable antennas that work together as one enormous instrument to observe faint cosmic radio waves. Conceived in the 1960s at the National Radio Astronomy Observatory (NRAO) to complement single-dish telescopes, it was preceded by the Green Bank Interferometer that helped develop key technologies in communication and signal correlation. 

Approved by Congress in 1972 and formally dedicated in 1980, the VLA was built on the remote Plains of San Agustin—chosen for its isolation from radio interference and its dry desert climate. This minimizes distortion from atmospheric water vapor. Each 82-foot dish can move on an altitude-azimuth mount and is periodically repositioned along rail tracks forming a Y-shaped array up to 23 miles across, allowing astronomers to adjust resolution and capture extraordinary detail from distant regions of the universe.

The National Radio Astronomy Observatory is a facility of the U.S. National Science Foundation operated under a cooperative agreement with Associated Universities, Inc.

Ultra Deep Field: Looking into Space, 12+ Billion Years Back in Time | Hubble

Ultra Deep Field: Looking into Space, 12+ Billion Years Back in Time | Hubble

This six-minute visual exploration of the Hubble Ultra Deep Field showcases the characteristics and contents of this landmark observation, as well as its four-dimensional nature across both space and time. In particular, galaxies are seen to more than 12 billion light-years away/12 billion years ago, allowing astronomers to trace the development of galaxies across cosmic time.

A deep field is a long exposure on a small field of view to observe the faintest objects possible. The Ultra Deep Field (UDF) represents the deepest visible light observation of the universe. Containing about 10,000 sources, the UDF provides a statistical sample of galaxies across the universe.

In this sequence, the three-dimensional model of the UDF data set uses NASA and other images and source catalogs. More than 5000 galaxies with cross-matched image cutout and distance measure are placed in their correct relative position throughout the long thin pyramid of the observation. To keep the fly-throughs succinct, the depth of the pyramid is shortened by a factor of a few hundred.

The visualization encompasses a suite of UDF science points in a single camera shot journey. Zooms, fades, fly-throughs, and overlay graphics visually express and highlight aspects such as the field of view, long exposure time, variety of galaxies, and extent across the observable universe. The critical idea that "looking farther out into space is also looking farther back in time" leads to examples, drawn directly from the data, of galaxy structure changing and growing over time.

The Ultra Deep Field and other deep field studies help astronomers study the distribution, characteristics, and development of galaxies across space and time.

This visualization is a product of the AstroViz Program of NASA's Universe of Learning.

A Pink Speckle in the Southern Sky over The Paranal Observatory in Chile | ESO

A Pink Speckle in the Southern Sky over The Paranal Observatory in Chile | ESO

This image shows the band of light from the Milky Way galaxy seemingly pouring into a telescope, right below the center of the image. Within the Milky Way right above the telescope, the Carina Nebula is visible as a pink spot. It marks the very center and focus of the image. Additionally, one of the Magellanic Clouds is visible in the left side of the picture right above the horizon.

This picture showcases the mesmerizing dark sky above the European Southern Observatory’s Paranal Observatory in Chile. The sky in the southern hemisphere is home to unique jewels like the Magellanic Clouds and one particularly special eye-catcher in this image—the Carina Nebula, a massive star-forming region visible here as a big pink spot right above one of the four Auxiliary Telescopes of ESO’s Very Large Telescope (VLT). 

This sight was a unique one for the French photographer Julien Looten, who captured the image. “It was an unforgettable moment,“ he said about finally seeing the Carina Nebula with his own eyes, as such a view is not possible from the northern hemisphere. However, Paranal’s location in the southern hemisphere and its uniquely dark skies make it possible to capture this breathtaking view. 

This nebula is home to Eta Carinae, a pair of massive short-lived stars that are shedding off large amounts of material. The structure of this cloud has been studied in detail with the VLT Interferometer, by linking together three Auxiliary Telescopes like the one in this image to create a huge “virtual” telescope.

Vera C. Rubin Observatory's Giant Eye on The Southern Sky | NOIRLab

Vera C. Rubin Observatory's Giant Eye on The Southern Sky | NOIRLab


High on the summit of Cerro Pachón in the Chilean Andes, NSF–DOE Vera C. Rubin Observatory stands like a watchtower, scanning the cosmos with a gaze wide enough to capture the entire sky of the southern hemisphere in a three-night sweep. Rubin Observatory is jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy’s Office of Science (DOE/SC). Rubin is a joint Program of NSF NOIRLab and DOE’s SLAC National Accelerator Laboratory that jointly operate Rubin.

Rubin will detect up to 10 million changes in the sky every night during its decade-long survey. Supernovae are an example of the most dynamic of these changes. They are often found by chance, although scientists have been looking for new ways to anticipate them. Previously, humans simply had to be supernova spotters, one of the most famous visually observed 42 supernovae over their lifetime. Spotting supernovae has become even easier in the last three decades through automation. Today, Rubin optimizes this automation with its 3200-megapixel LSST Camera and data processing software trained to catch even the faintest cosmic flicker. In the next decade, Rubin is expected to capture about ten million supernovae. What once took a lifetime of quiet observation can now be done every night, thousands of times over. From memory to machine, the mission remains the same: never miss a light in the dark.

Rubin Observatory is seen here beneath the southern sky. The Milky Way arcs overhead, and the Large Magellanic Cloud (LMC) can be seen on the left. Petr Horálek, the photographer, is a NOIRLab Audiovisual Ambassador.
