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!
After several weeks of trying different methods, the operations team successfully revived the stalwart Hubble Space Telescope, which experienced a payload computer fault back on June 13. The first images taken were of several unusual galaxies. Plus, Jupiter’s moon Io triggers radio emissions from the giant planet, and this week, What’s Up returns with a look at the Summer Triangle.
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.
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
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.
The payload computer aboard the Hubble Space Telescope stopped running on Sunday, June 13, 2021, and now the operations team is working to either save the module or switch to a backup. Plus, a protoplanetary disk, stellar mega-flares, missing dark matter, trans-Neptunian objects, and a review of Brandon Sanderson’s novel Skyward.
