Recent observations of twelve different stellar streams around the Milky Way have revealed the effects of dark matter, similar to how lights on a Christmas tree reveal the shape of the tree in dark. Plus, globular clusters, volcanoes, and an interview with Dr. Cathy Olkin from the Southwest Research Institute’s Lucy mission.
Researchers have potentially found a Neptune-sized exomoon orbiting a Jupiter-sized planet in a system with a Sun-like star, making it the second such potential exomoon discovered to date. Plus, rocket launches, This Week in Rocket History, and What’s Up.
China’s Chang’e-5 lunar lander has made the first in situ detection of water on the Moon, using reflectance spectroscopy from the surface of our natural satellite. Plus, all the news from the AAS virtual press conferences, including black holes and galaxies.
Scientists examined over 80,000 images from large telescopes and their sensitive instruments and found over 70 free-floating planets with the possibility for even more. Plus, a red giant supernova, new images of the Flame Nebula, and a review of Netflix’s “Don’t Look Up”.
With the successful launch of the JWST, the focus turns to the complicated process of unfurling the sunshield and unfolding the mirror. We’ll look at just where NASA is in the process and how much farther we have to go before first light. Plus, Earth and supernovae, and in this week’s What’s Up, we look forward to 2022’s astronomy events.
The Rocket Roundup team takes a look back at the rockets that launched in 2021, with a review of the statistics and some highlights (including that one telescope that could have ruined Christmas).
