NASA’s Dawn spacecraft, which orbited the asteroid Vesta in 2012, captured images of mysterious gullies on its surface, raising questions about their origins. The asteroid, known for its craters, also features channels that seem to contradict the harsh vacuum conditions of space. According to a study, researchers have proposed that brief liquid flows, possibly resulting…
A recent study published in Nature suggests that the Moon could be over 100 million years older than estimates based on rocks collected from its surface. The findings propose that the lunar surface underwent a “remelting” process 4.35 billion years ago, resetting the apparent age of lunar rocks. This research aligns with simulations of planetary…
A puzzling dark spot has been observed on Saturn’s icy moon, Enceladus, raising questions about the moon’s geological activity. The discovery, discussed during the 2024 American Geophysical Union (AGU) meeting in Washington, D.C., has captured the attention of researchers. According to reports, the spot, roughly a kilometre in size, was detected in images captured during…
