Pulsars as the Particle Accelerators of the Universe
Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake. Plus, missions close to home, large and distant objects, some pretty Hubble photos, and laser simulations of fast radio bursts.

Rocket Roundup for January 20, 2021
Join us for this week’s Rocket Roundup with host Dr. Pamela Gay as we look back at the launches that happened over the last week, including Blue Origin’s New Shepard, Virgin Orbit’s Launch Demo 2, one Chinese launch, and the Green Run test of the SLS.
Anatomical Dissection of Planetary Nebula Using Hubble Images
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.
Climate Change Affects Harvest, Rocks, Shorelines… and Truffles?
Climate change is a leading problem in today’s society, and today we have a quartet of stories on its effect on the world around us. Plus, more coverage from the AAS meeting with three stories on black holes, as well as dating supernovae, breaking a star, and magnetic chaos in a galaxy.
Powerful GRB is Actually Giant Flare From Magnetar in Nearby Galaxy
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.
Rocket Roundup for January 13, 2021
Join us for this week’s Rocket Roundup with guest host Dr. Pamela Gay as we look back at the launches and missions that happened over the last two weeks, including one from China, one from Arianespace, and one from SpaceX. Plus, the possibility of wooden satellites with community member Gordon Dewis.
Rocky Planet Found Orbiting Extremely Old Milky Way Star
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.
