Bright Comet's Tail Dazzles in Images from ESA/NASA SOHO Spacecraft
Greenbelt MD (SPX) Jan 23, 2025 From Jan. 11 to 15, 2025, a bright comet surged through images from the ESA (European Space Agency) and NASA SOHO (Solar and Heliospheric Observatory) spacecraft. Called C/2024 G3 (ATLAS), the comet made its closest pass to the Sun, or perihelion, on Jan. 13, soaring a mere 8 million miles (or 9% of the average Earth-Sun distance) from our star. These views of comet ATLAS were captured by SOHO's LASCO (Large Angle and Spectrometric Coronagraph) instrument, which uses a disk to cover the Sun's surf ... read more |

Massive asteroid strikes left no lasting impact on Earth's climate
London, UK (SPX) Dec 05, 2024 A new study led by researchers from University College London reveals that two massive asteroid impacts that occurred approximately 35.65 million years ago had no long-term effect on Earth's climate. Despite their immense size, the asteroids, which formed the Popigai crater in Siberia and the Chesapeake Bay crater in the United States, did not induce sustained climatic shifts. The asteroids struck Earth about 25,000 years apart during the late Eocene epoch. The larger of the two created the 60-mil ... read more
