Hycean worlds have hydrogen-rich atmospheres and are covered in oceans, making them prime candidates for the search for life outside our own solar system. These worlds are also more numerous and easier to find than Earth-like exoplanets. Plus, an update on the search for Planet 9 and how volcanoes may provide a climate safety valve.
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.
Once again, we find that dust is the culprit, this time causing a black hole to cast shadows out from the heart of its galaxy. Plus, a fossil galaxy in the Milky Way, newborn jets, and more.
Of course, our top story today is the touch-and-go sampling event on our favorite asteroid-to-hate, Bennu. OSIRIS-REx’s TAGSAM worked as expected, and now we’re waiting for the mass measurement of the sample taken. Plus, the Milky Way’s black hole is spinning too slowly to make jets, and the galaxy’s history can be found in atomic hydrogen filaments.
Galaxies have magnetic fields, too; ultraviolet flash spotted with supernova; multi-planet system directly imaged; new method finds ‘lost’ worlds
Join us today as we learn that galaxies have magnetic fields, too. Also, scientists are excited to catch the ultraviolet flash of a type Ia supernova and directly image a multi-planet extrasolar system. Finally, researchers have developed a new method for finding “lost” worlds in NASA TESS data (but no dinosaurs, thankfully).
