Two new studies have possibly identified regions on the Moon’s surface that could contain pieces of the lunar mantle, which would be possible sample targets for the Artemis mission. Plus, Venus gets a double flyby next week, and it’s all about asteroids and meteor showers in this week’s What’s Up.

Hubble Detects Water Vapor in Ganymede’s Atmosphere

Scientists analyzed archival data from the Hubble Space Telescope and found evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede. The water vapor is present due to thermal escape from the icy surface of the moon. Plus, a “fizzled” gamma-ray burst and all the exoplanets!

Using data collected by NASA’s Kepler Space Telescope, scientists have found four free-floating, or rogue, planets near the core of the Milky Way. These planets formed in discs in other planetary systems and were thrown out by gravitational interactions with larger planets. Plus, the early solar system, including ancient Earth, Jupiter’s chemistry, and Mercury’s core.

Two Neutron Star – Black Hole Mergers Detected

About 900 million miles away in two different galaxies, a black hole and a neutron star merged, and their gravitational waves have been detected here on Earth. These detections add another type of merger to the collection so far discovered. Plus, new composition data on Mars’ south polar cap and a look back at the Tunguska Event. #AsteroidDay

Discovery of Twin Supernovae Could Open Up Dark Energy Experiments

Researchers found that among about 50 supernovae, many had nearly identical spectra, paving the way for making more accurate distance calculations. These calculations, in turn, open up the possibility of using supernovae to better search for dark energy. Plus, OSIRIS-REx, Voyager I, planetary formation, and volcanoes on Mars.

Strange Supernova Appears Cool Before Exploding

Researchers find that the “oddball supernova” of a curiously cool, yellow star was lacking the hydrogen content expected, “stretching what is physically possible.” Plus, finding potentially habitable planets, a gamma-ray burst, ash clouds, and a new lunar map in this week’s What’s Up.
