Our coverage of last week’s AAS meeting continues with new work on the formation of planetary nebula based on Hubble Space Telescope images. Plus, a massive quasar in the early universe, water ice on Ganymede, a super-puff planet, and plans for taking spectra of Venus’ surface, featuring our guest, PSI scientist Dr. Darby Dyer.
Multiple international teams determine that a 2020 gamma-ray burst was actually a giant flare from a magnetar and that flare originated from a nearby galaxy. Plus, the Dark Energy Spectroscopic Instrument is ready for a new survey, NASA extends two planetary missions, and What’s Up in the night sky this next week.
Researchers using NASA’s TESS and the Keck Observatory found a rocky planet orbiting a 10-billion-year-old star in the Milky Way, up in the galaxy’s thick disk. Plus more planetary news from the AAS Winter Meeting, a magnetar, colliding galaxies, and gravitational wave news.
Scientists have found a method to use gravitational waves for understanding the early universe. Plus, an exoplanet with no atmosphere, spiders in space (CW), citizen science, and X-ray bubbles in the Milky Way. And the first of our new weekly segment: This Week in Sky Watching.
The first sunspot image released by the not-yet-completed Daniel K. Inouye Solar Telescope is highly detailed and a sample of the images to come. Plus, all the sample return missions, how the Sun bends light, and building blocks for organic molecules found in meteorites.
Due to breaking news, our lead story is about the collapse of the Arecibo telescope platform and its dish. Plus magnetars, gamma-ray bursts, sunspots, asteroids, dark matter, and a Kickstarter to preserve an historic observatory in Japan.
