This year's Penn State SETI Summit kicked off with a a lecture on how history will remember SETI pioneer Frank Drake, creator of the famous Drake Equation and leader of Project Ozma.

One of the outstanding mysteries in astronomy is how supermassive black holes gained so much mass so early in the Universe. The traditional theory is that stellar mass black holes merge, building up to supermassive levels. Another theory suggests that supermassive black holes might have collapsed directly out of enormous clouds of gas and dust. Astronomers using JWST and Chandra think they've discovered a black hole that's too massive, too early, and could only have formed from direct collapse.

Don't miss one of the best meteor displays of 2023, as the Perseids peak this coming weekend.

A portion of the metallic meteorites found on Earth have traces of magnetism. This is surprising since you need a larger world with an internal dynamo like the Earth. New research suggests that iron-heavy asteroids can collect into piles of rubble, with other space rocks forming a cold inner pile surrounded by a warmer liquid outer layer. As the core draws heat from the outer layer, it initiates convection and a small magnetic field that is detectable in the iron meteorites billions of years later.

Our modern technological civilization wouldn't have been possible without open-air combustion, which can only happen when atmospheric oxygen levels reach at least 18%. A new study asks if this could be a bottleneck for developing other advanced civilizations. Without at least 18% oxygen, fires won't easily burn, so technologies like steam power and combustion engines wouldn't be possible. Earth has only reached that level of atmospheric composition in the last 500 million years.

The coronal mass ejection on October 28th, 2021, was measured by missions on Earth, the Moon, and Mars for the very first time.
