Comet C/2025 F2 (SWAN) Likely Disintegrates Near Sun: Astronomers Confirm Fading Dust Cloud
In a bittersweet twist for skywatchers and astronomers, Comet C/2025 F2 (SWAN), a recently discovered celestial traveler, appears to have met an untimely end as it neared the sun. What initially looked like a promising display — a glowing green fuzz in the night sky — has likely disintegrated, leaving behind only a fading cloud of dust. Dr. Qicheng Zang, a postdoctoral fellow at Lowell Observatory, and Dr. Karl Battams of the US Naval Research Laboratory, both observed signs that the icy, rocky object may have crumbled under the sun’s intense heat and gravitational forces. While further observations are underway, all current indications point to a classic cometary breakup.
April's Full Moon Is a 'Micromoon' — Here's What That Means
Skywatchers, take note! April’s full moon, famously dubbed the “Pink Moon,” is set to light up the night sky this Saturday — but it may appear slightly smaller than you expect. That’s because this month’s full moon is a micromoon, a celestial event that occurs when the moon is at its farthest point from Earth in its orbit, making it look smaller and dimmer than usual.The micromoon will reach its peak illumination at 8:22 p.m.
Signs of Life? Scientists Spot Possible Biosignature on Distant Exoplanet K2-18b
In a groundbreaking discovery, astronomers using the James Webb Space Telescope have detected chemical signatures in the atmosphere of a distant exoplanet that may hint at the presence of life.
The planet in question, K2-18b, orbits a star about 1James WebbSpace Telescope on. While these findings are some of the most compelling potential biosignatures ever observed beyond our solar system, researchers are urging caution.

As space agencies race to establish permanent lunar settlements, a surprising challenge has emerged: keeping track of time. Scientists are now calling for precise clocks to be sent to the moon, and here's why.Due to Einstein’s theory of general relativity, time doesn’t pass at the same rate everywhere — even on Earth, seconds tick slightly faster on mountaintops than in valleys. On the moon, this difference is even more significant. A day on the lunar surface is about 56 microseconds shorter than on Earth.
