Interstellar Comet 3I/ATLAS: A Visitor from Beyond the Solar System

Comet 3I/ATLAS Today (Nov. 10, 2025): First Radio Signal Confirmed, Fresh Jet/Tail Images & What to Watch Next

Updated: November 10, 2025 — No threat to Earth; closest approach remains mid‑December. Key points at a glance What’s new today (Nov. 10) Radio proof of “cometness.” After weeks of speculation, astronomers have the clearest radio evidence yet that 3I/ATLAS behaves like a normal comet: MeerKAT detected hydroxyl (OH) absorption at 1665 and 1667 MHz during a deep observation on Oct. 24 while the object was near the Sun in the sky. OH is produced when water from a comet’s coma is broken apart by sunlight, and these specific radio lines are a textbook marker of that process. The team also notes earlier

Interstellar Comet 3I/ATLAS on Nov. 9, 2025: Tail Mystery, New Jet Images, and Where to Look This Week

Updated: November 9, 2025 What’s new today Today’s snapshot: why the comet’s look is confusing Some Nov. 5–9 images show a compact coma with little obvious dust tail, which has fueled social-media claims that 3I/ATLAS is behaving “unlike a comet.” But experts caution that viewing geometry matters: a tail can be foreshortened or lost in glare, and gas emissions can dominate the appearance around perihelion. Two days ago Space.com quoted Lowell Observatory’s Qicheng Zhang: there’s no solid evidence the coma “changed color”; instead, the gas coma is simply contributing more to the comet’s brightness. Meanwhile, a fresh deep stack highlighted

Rare Interstellar Comet 3I/ATLAS – a 10-Billion-Year-Old Time Capsule – Flies Past Mars

Comet 3I/ATLAS Today (Nov. 9, 2025): Post‑Perihelion Status, New Spacecraft Images, Visibility Guide — and What’s Hype vs Fact

Published: November 9, 2025 Comet 3I/ATLAS (C/2025 N1) — only the third confirmed interstellar object to sweep through our solar system — has reemerged from behind the sun and is sliding into the predawn sky this week. Fresh spacecraft imagery, a flurry of social media claims about its “missing tail,” and ongoing questions about color changes have made it the most watched rock‑ice visitor of the season. Here’s what’s new today, what’s reliable, and how to see it yourself. Space Key updates on Nov. 9 What astronomers agree on Fact‑check: today’s most shared claims “It has no tail — must

Sharper Black Hole Images Could Put Einstein’s Gravity to the Test: New Study Maps What Future Telescopes Must See (7 Nov 2025)

Brighter Than 10 Trillion Suns: Record Black Hole Flare 10 Billion Light‑Years Away

Date: November 7, 2025 Key points What happened—and why this one is different A Caltech‑led team reports an extraordinary flare from the supermassive black hole in AGN J2245+3743, first seen rising dramatically in 2018 and now recognized as a record‑setter for both luminosity and distance. At peak, it shone with the light of ~10 trillion suns, unmistakably towering above the AGN’s usual variability. California Institute of Technology+1 The peer‑reviewed study, published November 4, 2025 in Nature Astronomy, quantifies just how extreme the event is: the source brightened by more than a factor of 40, radiating a cumulative ~10⁵⁴ ergs—on par

Nov. 7, 2025: Beaver Supermoon Meets Taurid Fireballs — What to See Tonight and Why California’s Coasts Are on Alert

Date: November 7, 2025 Key points What’s happening now (Nov. 7) The Beaver Moon—November’s traditional full moon—was not only full on Wednesday but occurred within hours of perigee, making it the largest supermoon of 2025. That timing boosted apparent size and brightness compared with a typical full moon. While the precise moment of fullness has passed, the Moon remains strikingly bright tonight, an easy target for the naked eye. Space Photographers and stargazers worldwide have already shared images from this week’s show, underscoring how prominent the Moon looked at moonrise and moonset. Expect a similarly photogenic, near‑full disk this evening.

Alien Probe or Cosmic Relic? Interstellar Comet 3I/ATLAS Baffles Scientists (updated 27.10.2025)

3I/ATLAS Today (Nov. 7, 2025): New green-glow image, ‘color‑change’ myth debunked, and where to see the interstellar comet now

Updated: Nov. 7, 2025 — This roundup focuses on developments reported today (7.11.2025). Key updates at a glance What scientists reported today Green glow, “hidden” tail—here’s the physics. A new image captured with the Lowell Discovery Telescope shows 3I/ATLAS brightest through a filter sensitive to diatomic carbon (C₂), which fluoresces green in sunlight. The dust tail isn’t gone—you’re seeing it almost head‑on, so it blends with the coma and appears subdued. That geometry explains images where the tail seems to “disappear.” Live Science No, it hasn’t “changed color.” A preprint that compared sun‑skirting observations led to headlines about dramatic hue
