Milky Way’s Stellar Streams Highlight Dark Matter

Jan 19, 2022 | Daily Space, Dark Matter, Earth, Globular Cluster, Guest Interview, Milky Way, Rockets, Space China

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.

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.

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.

40 Hours of Observations Finds No Dark Matter in Galaxy AGC 114905

Astronomers using the Very Large Array in New Mexico spent 40 hours observing galaxy AGC 114905, which seemed to have little to no dark matter in 2019 observations. The new evidence shows there is no dark matter in the galaxy at all. Plus, more Hubble and JWST updates, an eclipse over Antarctica, and an interview with Dr. Franck Marchis about citizen science.

Dark Matter Delays Supernova Signal

A supernova first observed in 2016 will be replayed in a few years because of the light’s journey through a galaxy cluster and how dark matter gravitationally warps space-time. Plus, inactive centaurs, a Scottish ice wall, and a review of “Countdown: Inspiration4 Mission to Space”.

Simple Physics Explains Diamond Shapes of Ryugu and Bennu

Using a simple model based on granular physics, like those used for modeling sand or sugar deposits, scientists have recreated the diamond shape of asteroids Ryugu and Bennu in computer simulations. Plus, the origins of loner dwarf galaxies and this week’s What’s Up.
