A magnitude 7.2 earthquake shook the island nation of Haiti, destroying thousands of homes and resulting in the loss of over 1,400 people. Additionally, Tropical Depression Grace arrived and hampered rescue efforts. Plus, the asteroid Phaethon is outgassing sodium, studying Mars’ moons in the search for life, and how dust storms helped dry out Mars.
NASA’s TESS spacecraft, which is primarily used to search for exoplanets, has now observed a veritable symphony of pulsating red giant stars, each with its own internal vibrations. This work was presented at this week’s TESS Science Conference. Plus, some more climate change news (bad) and superflares may be less harmful to exoplanets than thought (good).
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!
The fossilized teeth and bones of baby dinosaurs found in northern Alaska may indicate that dinosaurs didn’t just summer in the Arctic but nested and raised their young there. Plus, the cosmic dawn, a cosmic hand, black holes, and preserving core samples for the future of science.
New high-resolution images captured by the SOFIA airborne telescope have given scientists the first clear view of a massive star-forming region here in the Milky Way, including an expanding bubble of gas. Plus, finding Earth-like exoplanets, detecting life on Earth, and this week’s What’s Up, featuring the Messier Catalogue.
In new research, scientists examined the populations of stars observed by the Kepler and K2 missions and found that the solar systems were different depending on the type of star involved. Plus, CHIME results, a brown dwarf’s atmosphere, a stream of stars in the Milky Way, and an interview with PSI’s Dr. Candice Hansen about the recent Ganymede flyby of NASA’s Juno spacecraft.
