Explanation: Jupiter reaches its 2026 opposition today, January 10. That puts our Solar System's most massive planet opposite the Sun and near its closest and brightest for viewing from planet Earth. In fact, captured only 3 days ago this sharp telescopic snapshot reveals excellent details of the ruling gas giant's swirling cloudtops, in light zones and dark belts girdling the rapidly rotating outer planet. Jupiter's famous, persistent anticyclonic vortex, known as the Great Red Spot, is south of the equator at the lower right. But two smaller red spots are also visible, one near the top in the northernmost zone,...

Explanation: Both Moon and Sun create beautiful ice halos in planet Earth's sky. In fact, the two brightest celestial beacons are each surrounded by a complex of ice halos in these photos of the sky above Chamonix-Mont-Blanc in France. The panels were recorded one night (left) and the following day at the end of December 2025. Similar ice halos appear in moonlight and sunlight because they are all formed through the geometry of flat, hexagonal ice crystals. The ice crystals reflect and refract light as they flutter in the cold atmosphere above the mountain resort. In the pictures both Moon...

A medical situation with an un-named crew member caused NASA to make the change...The agency said that it would not disclose the crew member's name or specific condition due to medical privacy.

Explanation: Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant toward the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only glimpsed through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy. Even though IC 342's light is dimmed and reddened by intervening cosmic clouds, this sharp telescopic image traces the galaxy's own obscuring dust, young star clusters, and glowing star...

This is a developing situation. NASA is considering a rare early return of Crew-11 after canceling a planned ISS spacewalk due to an unspecified medical issue with one astronaut. The crew member is stable, but the EVA — slated for Zena Cardman and Mike Fincke — was scrubbed. That spacewalk would’ve tied a career EVA record for Fincke. NASA says all options are on the table.

Explanation: Its popular nickname is the Spaghetti Nebula. Officially cataloged as Simeis 147 and Sharpless 2-240, it is easy to get lost following the looping and twisting filaments of this intricate supernova remnant. Seen toward the boundary of the constellations of the Bull (Taurus) and the Charioteer (Auriga), the impressive gas structure covers nearly 3 degrees on the sky, equivalent to 6 full moons. That's about 150 light-years at the stellar debris cloud's estimated distance of 3,000 light-years. The supernova remnant has an estimated age of about 40,000 years, meaning light from this powerful stellar explosion first reached the Earth...

Explanation: How complex is Jupiter? NASA's Juno mission to Jupiter is finding the Jovian giant to be more complicated than expected. Jupiter's magnetic field has been discovered to be much different from our Earth's simple dipole field, showing several poles embedded in a complicated network more convoluted in the north than the south. Further, Juno's radio measurements show that Jupiter's atmosphere shows structure well below the upper cloud deck -- even hundreds of kilometers deep. Jupiter's newfound complexity is evident also in southern clouds, as shown in the texture and color enhanced featured image taken last month. There, planet-circling zones...

She is a star of American science. A Stanford chair. A NASA collaborator. A role model for a generation of young researchers. But a chilling congressional investigation has found that celebrated geologist Wendy Mao quietly helped advance China's nuclear and hypersonic weapons programs – while working inside the heart of America's taxpayer funded research system. Mao, 49, is one of the most influential figures in materials science. She serves as Chair of the Department of Earth and Planetary Sciences at Stanford University, one of the most prestigious science posts in the country. Her pioneering work on how diamonds behave under...

Explanation: How was the unusual Red Rectangle nebula created? At the nebula's center is an aging binary star system that surely powers the nebula but does not, as yet, explain its colors. The unusual shape of the Red Rectangle is likely due to a thick dust torus which pinches the otherwise spherical outflow into tip-touching cone shapes. Because we view the torus edge-on, the boundary edges of the cone shapes seem to form an X. The distinct rungs suggest the outflow occurs in fits and starts. The unusual colors of the nebula are less well understood, however, and speculation holds...

Explanation: Most galaxies have a single nucleus -- does this galaxy have four? The strange answer leads astronomers to conclude that the nucleus of the surrounding galaxy is not even visible in this image. The central cloverleaf is rather light emitted from a background quasar. The gravitational field of the visible foreground galaxy breaks light from this distant quasar into four distinct images. The quasar must be properly aligned behind the center of a massive galaxy for a mirage like this to be evident. The general effect is known as gravitational lensing, and this specific case is known as the...

Explanation: The Full Moon is the brightest lunar phase, and tonight you can stand in the light of the first Full Moon of 2026. In fact, the Moon's full phase occurs on January 3 at 10:03 UTC, while only about 7 hours later planet Earth reaches its 2026 perihelion, the closest point in its elliptical orbit around the Sun, at 17:16 UTC. January's Full Moon was also not far from its own perigee, or closest approach to planet Earth. For this lunation the Moon's perigee was on January 1 at 21:44 UTC. You can also spot planet Jupiter, near its...

Explanation: In 2011, on January 20, NASA's NanoSail-D2 unfurled a very thin and very reflective 10 square meter sail becoming the first solar sail spacecraft in low Earth orbit. Often considered the stuff of science fiction, sailing through space was suggested 400 years ago by astronomer Johannes Kepler, who had observed comet tails blown by the solar wind. But modern solar sail spacecraft designs, like NanoSail-D2, Japan's interplanetary spacecraft IKAROS, or the Planetary Society's Lightsail A, rely on the small but continuous pressure from sunlight itself for thrust. Glinting in the sunlight as it circled planet Earth, NanoSail-D2's solar sail...

Anthony and Gavin talk about a female Astronaut that sabotaged the NASA space station because she wanted to leave.

Explanation: Cycle 25 solar maximum made 2025 a great year for aurora borealis (or aurora australis) on planet Earth. And the high level of solar activity should extend into 2026. So, while you're celebrating the arrival of the new year, check out this spectacular auroral display that erupted in starry night skies over Kirkjufell, Iceland. The awesome auroral corona, energetic curtains of light streaming from directly overhead, was witnessed during a strong geomagnetic storm triggered by intense solar activity near the March 2025 equinox. This boreal skyscape captures the evocative display in a 21 frame panoramic mosaic.

Explanation: What created the Waterfall Nebula? The origin is still being researched. The structure, officially designated Herbig-Haro 222, appears in the region of NGC 1999 in the Great Orion Molecular Cloud complex. The elongated gaseous stream stretches about ten light years but appears similar to a long waterfall on Earth. Recent observations indicate that HH-222 is likely a gigantic gaseous bow shock, similar to a wave of water caused by a fast-moving ship. The origin of this shock wave is thought to be a jet outflow from the multiple star system V380 Orionis off the lower left of the frame....

Explanation: Yes, but can your comet tail do this? No, and what you are seeing is not the tail of a comet. The picture features a cleverly overlayed time-lapse sequence of a group of satellites orbiting Earth together in June. Specifically, these are Starlink communications satellites in low Earth orbit reflecting back sunlight before sunrise to Inner Mongolia, China. Although the satellites appear to the human eye as points, the 20-second-long camera exposures caused them to appear as short streaks. Currently there are over 9000 Starlinks in orbit, with more being launched nearly every week. Other satellite constellations are also...

Teen Discovers 1.5M Space Objects With AI | Image by Matteo Paz @matteopaz06/X A recently graduated high school student made an artificial intelligence breakthrough using retired NASA data, which led to a public recruitment pitch from the agency’s new administrator on social media, including a fighter jet ride. The teenager from Pasadena, California, used AI to identify approximately 1.5 million previously unrecognized cosmic objects in archival NASA data. His work went viral on X, capturing the attention of senior space officials. This led to an informal public recruitment pitch from Jared Isaacman, the billionaire entrepreneur recently appointed as NASA administrator....

Musk and Gor disliked each other since before Trump reclaimed power on Jan. 20 — with the Tesla and SpaceX CEO describing Gor as “sleazy” during the transition and questioning his staffing picks. But the world’s richest man had the president’s ear and friendship through last week. Simmering behind the scenes was a grudge nursed by Gor over a March 6 Cabinet meeting, during which Musk “humiliated” him by slamming the pace of staffing the administration, said the sources, each of whom have interacted closely with Gor. “He was bragging to other people that he was going to get one...

Explanation: This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The featured image was taken by an amateur astronomer in Leesburg, Florida, USA over three nights last month. It was captured in three primary colors but with extra detail provided by specific emission by hydrogen gas. The Crab Nebula spans about 10...
