The Knotty Problem of Matter Asymmetry Might Be Solved By Extending Physics
Why is the Universe filled with matter? Why isn't it an equal amount of matter and antimatter? We still don't know the answer, but a new approach looks at the symmetries of extended models of particle physics and finds a possible path forward. It's a knotty problem that may just have a knotty solution.

New Radar Data Dries Up Hope For Subsurface Liquid Water On Mars
Remember back in 2018 when there was a discovery of a briny “lake” underground near the Martian south pole? Pepperidge Farm probably does, and anyone that works there that’s interested in space exploration will be disappointed to hear that, whatever might be causing the radar signal that finding was based on, it’s most likely not a lake. At least according to new data collected by the Mars Reconnaissance Orbiter (MRO) and published recently in Geophysical Research Letters by lead author Gareth Morgan of the Planetary Science Institute and his colleagues.

Sun-watcher SOHO celebrates thirty years
On 2 December 1995 the ESA/NASA Solar and Heliospheric Observatory (SOHO) blasted into space – on what was supposed to be a two-year mission.
From its outpost 1.5 million km away from Earth in the direction of the Sun, SOHO enjoys uninterrupted views of our star. It has provided a nearly continuous record of our Sun’s activity for close to three 11-year-long solar cycles.
