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.

Researchers hypothesize that blobs in post-Big Bang fields of energy, known as Q-balls, could explain how matter came to dominate over antimatter in our Universe, and they plan to use gravitational waves to find their evidence. Plus, a crewed launch to the ISS features Japanese tourists, NASA selects the latest astronaut class, and What’s Up is the Geminids.

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.
