All the Rockets and All the Rocks
With the release of JWST’s first science images behind us, we now catch up on all the rocket launches of the past few days. Meanwhile, Bennu continues to be a favorite research topic and is the subject of three new papers released this week. Plus, pulsar-orbiting planets, and this week in rocket history, we look back at GEOTAIL.

JWST Launch Still Scheduled for Christmas Eve
Dr. Pamela takes a deep dive into her feelings about the JWST, its pending launch, and just what the telescope means to the astronomical community. Plus, general relativity is still true, a huge filament of gas in the Milky Way, and we interview Hamed Valizadegan, project lead for ExoMiner.
Sublimating Nitrogen Responsible for Pluto’s Icy Polygons
New models of sublimating nitrogen show that the process creates enough heat to drive the formation and texture of the polygons in Sputnik Planitia. Plus, black holes, star formation, and an interview with Dr. Jonathan McDowell, orbital police.
Massive Thwaites Glacier in Antarctica at Risk of Collapse
A team of scientists collected cores and modeled ice cliff failure and found that Thwaites Glacier in Antarctica is melting more quickly than ever and could be at risk of collapse, threatening global coastlines with almost a meter of sea-level rise. Plus, new results from Percy, and this week’s What’s Up.
Rocket Roundup for December 15, 2021
On Rocket Roundup, launches include the latest from Rocket Lab, a Blue Origin crewed launch, several Chinese launches, and a pair of Russian communication satellites. Plus, this week in rocket history, we look back at Apollo 17.
New, Deep Images of Milky Way’s Black Hole Show Stars Moving
Using the ESO’s Very Large Telescope Interferometer, scientists have obtained the deepest and sharpest images of Sagittarius A*, the black hole at the center of the Milky Way. They tracked the orbits of stars and were able to more precisely measure the mass of the black hole. Plus, new ways to research meteors, and a review of a Peak Design camera anchor system.
Overlooked Exoplanet Found by Citizen Scientists
Using data provided by the Backyard Worlds: Planet 9 citizen science project, volunteers found a possible large planet or brown dwarf orbiting its star at a distance of more than 1,600 astronomical units. Plus, NASA launches the Imaging X-ray Polarimetry Explorer, and we review Ghostbusters: Afterlife.
