Scientists Trace Rare Cosmic Outburst to a Massive Planetary Collision Around Gaia20ehk
Astronomers have reported evidence of two planets colliding around a distant Sun-like star, Gaia20ehk, located about 11,000 light-years away. The star's light output remained steady until 2016, when it exhibited three minor dimming events; by 2021, the light curve reportedly "went completely bonkers." Follow-up infrared observations revealed a burs...

Record-Breaking Drill Beneath Antarctic Ice Reveals Ancient Open Ocean and Future Sea Level Risks
Scientists drilled deeper than ever beneath the West Antarctic Ice Sheet and found sediment and marine remains showing the area was once open ocean. The 23-million-year record offers key clues about past melting, helping researchers better predict how quickly the ice sheet could retreat and affect future global sea levels.

Arctic Report Card Flags Fast Warming, Record Heat and New Risks
The 2025 Arctic Report Card shows the Arctic is warming faster than expected, with record heat, shrinking ice, stronger storms, and rusting rivers. Scientists warn that rising temperatures are reshaping ecosystems, threatening water safety, and increasing risks for Arctic communities. The changes highlight how quickly climate impacts are unfolding,...

Interstellar Comet 3I/ATLAS Shows Rare Wobbling Jets in Sun-Facing Anti-Tail
Interstellar comet 3I/ATLAS reveals rare wobbling jets in its sun-facing anti-tail, stretching over 620,000 miles. Observed from July to September 2025, the jets indicate the comet’s icy core rotates once every 15.5 hours. As only the third interstellar object known, 3I/ATLAS provides unique insights into cometary behaviour and formation in dista...

Strongest Solar Flare of 2025 Sends High-Energy Radiation Rushing Toward Earth
A powerful X5.1 solar flare on November 11, 2025, sent high-speed protons toward Earth, producing the strongest radiation spike detected in nearly two decades. The event caused a rare ground-level enhancement, briefly raising radiation at flight altitude to ten times normal. While not dangerous this time, scientists warn larger flares could threate...

Boiling Oceans May Hide Beneath Icy Moons, New Study Suggests
A new study suggests that icy moons such as Mimas and Enceladus may host boiling subsurface oceans triggered by thinning ice shells and falling pressure. This low-temperature boiling could still support life beneath the surface. The research also explains geological features on larger icy moons and strengthens their potential as sites for finding e...

Antarctica Nears Irreversible Climate Tipping Point, Scientists Warn
Antarctica is approaching irreversible climate thresholds, scientists warn. Rapid melting of the West Antarctic Ice Sheet, record-low sea ice, and collapsing ocean systems could raise global sea levels by over 3 m. These interconnected changes threaten coastal cities and ecosystems, urging immediate emission cuts to prevent cascading global consequ...

China and NASA Coordinate to Avoid Satellite Collision for the First Time
China’s CNSA made history by alerting NASA to a possible satellite collision—marking the first instance of Beijing warning Washington in orbit. With Earth’s orbits growing crowded from megaconstellations like Starlink and Guowang, the event signals a new phase of cooperation in global space traffic control and shared responsibility for orbita...

NASA Confirms Brightening Comet SWAN Could Be Visible With Binoculars: When and Where to See It
Comet SWAN (C/2025 R2), discovered via NASA’s SOHO spacecraft, is rapidly brightening as it nears its October 20–21 Earth flyby. Skywatchers should look to the western horizon after sunset to spot its vivid green coma and tail — possibly visible to the naked eye in dark conditions.

Mysterious Asteroid Impact Found in Australia, But the Crater is Missing
Scientists have identified 11-million-year-old glass fragments in South Australia that record a massive asteroid impact never before known. Despite the event’s magnitude, the crater remains undiscovered, raising new questions about how often large asteroids have struck Earth and their role in shaping its surface.

Solar Storm From Four Sun Eruptions Could Cause Minor Geomagnetic Activity
A burst of solar activity could soon paint Earth’s skies with auroras. Between October 11 and 13, the Sun fired four coronal mass ejections toward Earth, expected to arrive October 15–17. NOAA predicts mild G1 geomagnetic storms that could trigger colorful northern lights visible across high and even mid-latitude regions.

Butterfly-Shaped Hole in the Sun Could Spark Solar Storms Worldwide This Weekend
A giant butterfly-shaped coronal hole on the Sun is blasting solar wind toward Earth, expected to trigger geomagnetic storm conditions on Sept. 13–14. Forecasts suggest possible G1 to G2 levels, raising chances for auroras across mid- and high-latitudes. Scientists note the equinox effect could intensify activity, offering a prime opportunity for...

NASA Tracks Newly Discovered Bus-Sized Asteroid as It Flies Past Earth
A newly discovered asteroid, 2025 QV5, about the size of a school bus, will safely pass Earth today at a distance of 500,000 miles, roughly twice as far as the moon. NASA’s JPL notes it will not return this close again until September 2125. Scientists are tracking its path to refine orbital predictions and future flybys.

Lunar Eclipse September 2025: Know Who Will Get to See the Blood Moon on September 7
On September 7–8, 2025, a total lunar eclipse will turn the Moon deep red for 82 minutes. Visible to 70–85% of Earth’s population, it will be the longest such event since 2022. Skywatchers in Asia, Africa, Australia, and parts of Europe will enjoy the full celestial show.
