Comet 3I/ATLAS Today (Dec. 26, 2025): Wobbling Jets Detected in a Rare Sun-Facing Tail as the Interstellar Visitor Departs

Comet 3I/ATLAS Today (Dec. 26, 2025): Wobbling Jets Detected in a Rare Sun-Facing Tail as the Interstellar Visitor Departs

Dec. 26, 2025 — Comet 3I/ATLAS is already on its way out of our neighborhood, but it’s still managing to surprise astronomers on the way to the cosmic exit ramp. Today’s coverage centers on a fresh scientific twist: researchers have identified wobbling jet structures inside an even rarer feature—an apparent tail that points toward the Sun, not away from it.

Doomed SpaceX Starlink Satellite 35956 Photographed From Orbit After In‑Space Anomaly Spreads Debris

Doomed SpaceX Starlink Satellite 35956 Photographed From Orbit After In‑Space Anomaly Spreads Debris

Dec. 24, 2025 — A rare, close-up orbital photograph has provided a clearer look at a SpaceX Starlink satellite that suffered an in-space anomaly and is now tumbling toward reentry, while a growing debris field underscores how quickly low Earth orbit can become more complicated — and potentially more dangerous — as megaconstellations expand.

ISRO’s ‘Baahubali’ LVM3-M6 Launches BlueBird 6 (BlueBird Block-2) for AST SpaceMobile, Setting a New Heaviest-Payload Record — Dec. 24, 2025

ISRO’s ‘Baahubali’ LVM3-M6 Launches BlueBird 6 (BlueBird Block-2) for AST SpaceMobile, Setting a New Heaviest-Payload Record — Dec. 24, 2025

India’s heavy-lift launch vehicle LVM3-M6 — popularly dubbed “Baahubali” — roared off the Second Launch Pad at the Satish Dhawan Space Centre in Sriharikota on December 24, 2025, successfully deploying BlueBird 6, a next-generation communications spacecraft for U.S.-based AST SpaceMobile. The mission, officially described by ISRO as the LVM3-M6 / BlueBird Block-2 commercial launch, is a landmark on two fronts: it is the heaviest payload ever launched by LVM3 into Low Earth Orbit and a high-visibility demonstration of India’s expanding role in global, fee-for-service satellite launches. www.ndtv.com+2ISRO+2

Comet 3I/ATLAS Today (22 December 2025): The Latest Science, Spacecraft Views, and “Radio Signal” Reality Check

Comet 3I/ATLAS Today (22 December 2025): The Latest Science, Spacecraft Views, and “Radio Signal” Reality Check

As of 22.12.2025, the interstellar comet 3I/ATLAS—only the third confirmed object from beyond our solar system—is already on its way out again. Its closest pass by Earth happened just days ago, and while the comet never came anywhere near “close” in a human sense, the flyby has triggered a wave of fresh data releases, rapid-response observations, and some internet-fueled mythology.

Comet 3I/ATLAS Today (Dec. 20, 2025): Europa Clipper’s UV Surprise, Parker Solar Probe Images, and the Latest Forecast

December 20, 2025 — The rare interstellar visitor known as Comet 3I/ATLAS is now past its closest approach to Earth and heading back out toward the outer solar system. But “past” doesn’t mean “gone.” Today’s updates include a new research release describing ultraviolet measurements from NASA’s Europa Clipper that captured the comet when Earth- and Mars-based observers had limited views, plus fresh details on how NASA’s Parker Solar Probe tracked the comet near the Sun—right through the glare that normally hides objects like this from ground-based telescopes.

The Role of Starlink in Scientific Research: How SpaceX’s Satellite Internet Is Transforming Field Science, Earth Observation, and Space Missions—While Challenging Astronomy

The Role of Starlink in Scientific Research: How SpaceX’s Satellite Internet Is Transforming Field Science, Earth Observation, and Space Missions—While Challenging Astronomy

Starlink—the low Earth orbit satellite internet network built by SpaceX—was designed to solve a commercial problem: fast, low-latency connectivity anywhere on Earth. But as the constellation has scaled into the thousands of satellites and millions of users, it has quietly become something else, too: a new layer of scientific infrastructure.

Jared Isaacman NASA Today: Senate Confirms Billionaire Spaceflight Veteran as New NASA Administrator (Dec. 17, 2025)

WASHINGTON — Jared Isaacman, the billionaire entrepreneur and private astronaut best known for commanding the all-civilian Inspiration4 mission and SpaceX’s Polaris Dawn, was confirmed by the U.S. Senate on Wednesday, December 17, 2025, to lead NASA. The confirmation vote was 67–30, elevating Isaacman to the role of NASA administrator at a moment when America’s civil space program is juggling high-profile Moon and Mars ambitions, intense geopolitical competition with China, and renewed political scrutiny over budgets and contracting.

Moon in December 2025: Waning Crescent Tonight, New Moon Date, Geminids Peak, and NASA’s Latest Lunar Push

Moon in December 2025: Waning Crescent Tonight, New Moon Date, Geminids Peak, and NASA’s Latest Lunar Push

December 14, 2025 is shaping up as one of the most “Moon-centric” nights of the month—not because the Moon is bright and dominating the sky, but because it isn’t. With the Moon now a waning crescent and shrinking toward the New Moon on December 19, skywatchers are getting darker skies right as the Geminid meteor shower reaches its peak window. WUSF+2Space+2

NASA Loses Contact With MAVEN Mars Orbiter: What the Silent Spacecraft Means for Future Mars Missions

NASA’s MAVEN spacecraft, which has been orbiting Mars since 2014, stopped talking to Earth on December 6, 2025. Before the blackout, telemetry showed the spacecraft behaving normally as it slipped behind Mars in its usual orbit. But when MAVEN emerged from the planet’s far side, NASA’s Deep Space Network didn’t hear the expected carrier signal.NASA Science+1
