The Tibet ASγ Experiment Finds Evidence of PeVatrons

The Tibet ASγ Experiment Finds Evidence of PeVatrons

Using substantial ground arrays and underground muon detectors, the Tibet ASγ Collaboration has captured evidence of ultra-high-energy gamma rays that are thought to be the result of nuclear interactions between cosmic rays and interstellar gas. Plus, OSIRIS-REx, Ingenuity, InSight, comet 2I/Borisov, and things getting hit (or not) by other things.

Event Horizon Telescope Captures New Image of Black Hole in M87

The Event Horizon Telescope collaboration released a new image yesterday that shows the black hole in M87 once again, but this time, with new details. Using polarized light, the team was able to capture photographic evidence of magnetic fields. Plus, Jupiter’s winds, baby stars, fossilized plants under Greenland’s ice, and our weekly What’s Up segment.

Iceland Has a New Volcanic Fissure Erupting in Fagradalsfjall

After much “will it / won’t it” over the last few weeks in the wake of increased (and then decreased) seismic activity, an eruption in Iceland finally started with a brand new fissure near Fagradalsfjall. No lives are threatened, so Pamela is ecstatic. Plus, arctic methane, a new basalt type, spiders on Mars, Titan’s atmosphere, and an interview with PSI scientist Dr. Nick Castle about volcanoes

LPSC: Studying Microorganisms Trapped in Salt as Martian Analog

We interview a pair of scientists who have examined microorganisms embedded in halite crystals to determine the feasibility of finding similar evidence of past life in return samples from Mars. Plus, ‘Oumuamua, Bennu, Ryugu, winds on Jupiter and a space jellyfish.
