Solar activity has kicked into high gear already this week with two powerful X-class solar flares erupting from active region AR4274 — one on Nov. 9 and another early Nov. 10 — each potentially firing coronal mass ejections (CMEs) toward Earth.

Astronomer catches sight of interstellar Comet 3I/ATLAS returning to the predawn sky — Here's how you can too
November 10, 2025
After briefly escaping from Earth’s view during a (very) close approach to the sun on Oct. 30, Comet 3I/ATLAS can finally be seen through amateur telescopes again, though it’s impossible to say how long the interstellar invader will remain detectable…
NASA's new Mars mission: These twin satellites could reveal how the Red Planet lost its atmosphere
November 10, 2025
Mars is about to receive a double dose of attention. This weekend, a pair of identical NASA satellites will launch together to help reveal how the Red Planet lost its thick atmosphere and liquid water — one of its oldest mysteries, and a key to understanding how it transformed from a once-habitable world into the frozen desert it is today.
Scheduled for liftoff no earlier than Sunday (Nov. 9)…
Watch Blue Origin's huge New Glenn rocket launch a NASA 'ESCAPADE' to Mars on Nov. 12 after weather delay
November 10, 2025
UPDATE for 9 p.m. EST: SCRUB! Blue Origin has called off today’s planned launch of the New Glenn NG-2 mission with NASA’s ESCAPADE Mars launch due to bad weather, specifically a thick cloud rule, the company said. Read our full launch scrub story here. Blue…
Northern lights may be visible in 22 US states tonight
November 7, 2025
The northern lights and southern lights could receive a considerable boost again tonight as Earth braces for impact from a powerful coronal mass ejection (CME) hurled from the sun during yesterday’s M7.4 solar flare.
The speedy CME is forecast to arrive late tonight or…
See stunning photos of November's full 'Beaver Moon' — the biggest supermoon of 2025
November 7, 2025
The November full moon put on a magnificent show for stargazers on Nov. 5, as the largest and brightest supermoon of 2025 flooded the sky with reflected sunlight mere hours before it reached its closest point to Earth in its 27-day orbit.
November’s full moon is also known as the “Beaver Moon”, in reference to the period when the buck-toothed mammals become particularly active in…
Surprise geomagnetic storm arrives early as NOAA warns more solar impacts are on their way today
November 7, 2025
A geomagnetic storm surprised forecasters overnight as material from recent solar eruptions arrived earlier than expected, briefly reaching strong (G3) levels. Now, NOAA has a G3 geomagnetic storm watch in effect as Earth braces for further impacts from multiple coronal mass…
Sun unleashes 2 colossal X-class solar flares, knocking out radio signals across the Americas and Pacific
November 6, 2025
The sun has fired off not one but two colossal X-class solar flares in less than 12 hours, causing radio blackouts across the sunlit portion of Earth at the time of eruption and marking a dramatic uptick in solar activity.
Each of the X-flares was accompanied by a…
How AI fixed the James Webb Space Telescope's blurry vision
November 6, 2025
Telescope has been suffering from blurry vision.
But a team of Australian researchers created an AI algorithm that fixes the problem — a major relief for the scientific community, which hopes to use the instrument to search for exoplanets around stars in our Milky Way galaxy.
The affected instrument is the Aperture Masking Interferometer (API), designed and built by a team of astronomers led by…
