Artemis Astronauts Will Deploy New Seismometers on the Moon April 18, 2024
Back in the 1960s and 1970s, Apollo astronauts set up a collection of lunar seismometers to detect possible Moon quakes. These instruments monitored lunar activity for eight years and gave planetary scientists an indirect glimpse into the Moon’s interior. Now, researchers are developing new methods for lunar quake detection techniques and technologies. If all goes […]

Ice Deposits on Ceres Might Only Be a Few Thousand Years Old April 18, 2024
The dwarf planet Ceres has some permanently dark craters that hold ice. Astronomers thought the ice was ancient when they were discovered, like in the moon’s permanently shadowed regions. But something was puzzling. Why did some of these shadowed craters hold ice while others did not? Ceres was first discovered in 1801 and was considered […]

The Mystery of Cosmic Rays Deepens April 18, 2024
Cosmic rays are high-energy particles accelerated to extreme velocities approaching the speed of light. It takes an extremely powerful event to send these bits of matter blazing through the Universe. Astronomers theorize that cosmic rays are ejected by supernova explosions that mark the death of supergiant stars. But recent data collected by the Fermi Gamma-ray […]

Are Titan's Dunes Made of Comet Dust? April 18, 2024
A new theory suggests that Titan’s majestic dune fields may have come from outer space. Researchers had always assumed that the sand making up Titan’s dunes was locally made, through erosion or condensed from atmospheric hydrocarbons. But researchers from the University of Colorado want to know: Could it have come from comets? The dunes of […]
