7,000 years ago, a star exploded. All that remains are these ethereal wisps of the #VeilNebula. Once as bright as a crescent Moon for our ancient ancestors, this supernova remnant (Cygnus Loop) now spans over 5x the Full Moon's size, 1,400 light-years away.

Fresh Tiger Stripes on Enceladus – Aug 25, 2024
Do underground oceans vent through canyons on Saturn’s moon Enceladus? Ice-spewing “tiger stripes” seen in this false-color image from Cassini suggest so.

On March 14, 2025 (Friday), the "Worm Moon"—March's full moon—will rise. Named by Native Americans, it marks the time when soil warms and earthworms emerge, signaling spring. This time, it’ll pair with a lunar eclipse, turning the moon red for about an hour.

Uranus: The Coldest Planet in the Solar System!
Despite being closer to the Sun than Neptune, Uranus holds the record for the lowest temperature at -224°C (-371°F). Its axis is tilted 98°, making it roll sideways as it orbits….
