Radiating Exoplanet Discovered in “Perfect Tidal Storm” April 20, 2024
Can tidal forces cause an exoplanet’s surface to radiate heat? This is what a recent study accepted to The Astronomical Journal hopes to address as a team of international researchers used data collected from ground-based instruments to confirm the existence of a second exoplanet residing within the exoplanetary system, HD 104067, along with using NASA’s […]

The Giant Planets Migrated Between 60-100 Million Years After the Solar System Formed April 19, 2024
Untangling what happened in our Solar System tens or hundreds of millions of years ago is challenging. Millions of objects of wildly different masses interacted for billions of years, seeking natural stability. But its history—including the migration of the giant planets—explains what we see today in our Solar System and maybe in other, distant solar […]

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 […]
