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.

Q-balls Knock Matter Into Dominance Over Antimatter After Big Bang

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.

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.
