The Giant Planets Migrated Between 60-100 Million Years After the Solar System Formed
|
|
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
|
|
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
|
|
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
|
|
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 …

NASA Confirms that a Piece of its Battery Pack Smashed into a Florida Home
|
|
NASA is in the business of launching things into orbit. But what goes up must come down, and if whatever is coming down doesn’t burn up in the atmosphere, it will strike Earth somewhere. Even Florida isn’t safe. Careful consideration goes into releasing debris from the International Space Station. Its mass is measured and calculated …

Are Titan's Dunes Made of Comet Dust?
|
|
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 …

The Solar Wind is Stripping Oxygen and Carbon Away From Venus
|
|
The BepiColombo mission, a joint effort between JAXA and the ESA, was only the second (and most advanced) mission to visit Mercury, the least explored planet in the Solar System. With two probes and an advanced suite of scientific instruments, the mission addressed several unresolved questions about Mercury, including the origin of its magnetic field, …

The Solar Eclipse Like We’ve Never Seen it Before
|
|
You had to be in the right part of North America to get a great view of the recent solar eclipse. But a particular telescope may have had the most unique view of all. Even though that telescope is in Hawaii and only experienced a partial eclipse, its images are interesting. The Daniel K. Inouye …

The Milky Way’s Most Massive Stellar Black Hole is Only 2,000 Light Years Away
|
|
Astronomers have found the largest stellar mass black hole in the Milky Way so far. At 33 solar masses, it dwarfs the previous record-holder, Cygnus X-1, which has only 21 solar masses. Most stellar mass black holes have about 10 solar masses, making the new one—Gaia BH3—a true giant. Supermassive black holes (SMBH) like Sagittarius …
