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.
The Event Horizon Telescope collaboration released a new image yesterday that shows the black hole in M87 once again, but this time, with new details. Using polarized light, the team was able to capture photographic evidence of magnetic fields. Plus, Jupiter’s winds, baby stars, fossilized plants under Greenland’s ice, and our weekly What’s Up segment.
Today we look at three astronomical stories! First, simulations show that rocky Super-Earth sized exoplanets have a Jupiter-sized guardian. Then a study of over 700 quasars shows they form because of… magnetic fields, of course! And finally, spare observation time leads to the discovery of a metal-poor globular cluster near the Andromeda Galaxy.
Quick plunge in sunlight caused Snowball Earths; remnants of globular cluster found; loop quantum cosmology breaks our brains
Join us today as we go back in time and examine what caused Earth to become a snowball… more than once. We also take a look at a dismembered globular cluster found at the edge of the Milky Way. And finally, Dr. Pamela gets to explain loop quantum cosmology. Wish her luck!
