Active Black Hole’s Surge in Brightness Due to Magnetic Flip

Active Black Hole’s Surge in Brightness Due to Magnetic Flip

A luminous black hole already classified as an active galactic nucleus brightened suddenly in recent ground and space observations, and the cause may be due to a sudden flip in the magnetic poles. Plus, community science, rockets, Ingenuity, and an interview with Dr. Cathy Weitz from Planetary Science Institute.

Massive Thwaites Glacier in Antarctica at Risk of Collapse

A team of scientists collected cores and modeled ice cliff failure and found that Thwaites Glacier in Antarctica is melting more quickly than ever and could be at risk of collapse, threatening global coastlines with almost a meter of sea-level rise. Plus, new results from Percy, and this week’s What’s Up.

Perseverance Images Confirm Jezero Crater as Ancient Lake

A newly completed analysis of Perseverance’s first images from Mars finds that the landing site, Jezero Crater, was really a lake that was fed by a river, with sedimentary layers, flash floods, and strewn boulders. Plus, Central African biomass burning, Arctic permafrost melting, and we look at jewelry that celebrates upcoming missions.
