Hubble Telescope finishes 200,000 Earth orbits in style, studying a star explosion (opens the original)
Read excerpt
NASA's Hubble Space Telescope has now circled Earth 200,000 times, marking another extraordinary milestone for an observatory that was designed to operate for just 15 years. The Hubble Telescope completed its 200,000th orbit on Sept. 19, more than 36 years after it launched aboard the space shuttle Discovery in April 1990. During that time, the telescope has traveled more than 5 billion miles (8 billion kilometers) around Earth and made more than 1.7 million observations of the universe. This mo
'Mars constantly throws surprises at you': Perseverance rover finds evidence of ancient hot water in Red Planet crater (opens the original)
Read excerpt
Mars may have been a much wetter and more geologically active world than it is today, with water repeatedly coursing through its rocks in different forms, a new study suggests. The discovery comes from a region along the edge of Mars' Jezero Crater known as the Margin Unit. NASA's Perseverance rover has been exploring the area since 2023, and its observations reveal evidence of at least three distinct episodes of water interacting with Martian rocks — including one involving hot groundwater circ
A NASA spacecraft just found a giant new crater on the moon. Here's why everyone's talking about the 'once-in-a-century' discovery (opens the original)
Read excerpt
A newly discovered crater on the moon is giving scientists a rare glimpse into the immediate aftermath of a lunar impact. Named McGetchin crater, the feature formed sometime between April 11 and May 22 in the year 2024 when an asteroid or comet fragment struck the moon. Measuring about 728 feet (222 meters) across and roughly 141 feet (43 meters) deep, McGetchin is the largest newly formed impact crater identified by NASA's Lunar Reconnaissance Orbiter (LRO). In fact, it's the largest newly form
NASA's doomed Swift space telescope restarts science work after rescue mission fails (opens the original)
Read excerpt
NASA's Neil Gehrels Swift Observatory is back to studying the universe after spending months in a low-drag configuration while awaiting an orbital rescue mission that ultimately fell short. Mission controllers restarted two of Swift's three science instruments — its X-ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT) — on Aug. 26. Both instruments had been shut down in February as part of an effort to minimize atmospheric drag and keep the aging spacecraft in orbit long enough for ano
Astronomers discover a giant, rocky 'mega-Earth' 23 times more massive than our planet (opens the original)
Read excerpt
Astronomers have discovered an unusually massive, dense exoplanet that challenges conventional ideas about how rocky planets form. Called GJ 523b, the exoplanet is about 2.5 times wider than Earth but packs roughly 23 times our planet's mass into that relatively compact size. Worlds this large and dense are sometimes referred to as "mega-Earths," an informal term for unusually massive, predominantly rocky planets. GJ 523b's high density suggests it contains relatively little atmosphere despite b
