Icy Comets Can Alter Exoplanet Atmospheres and Shape Habitability
Earth's history was shaped by the bombardment of icy and rocky bodies. These impacts delivered volatiles and organic compounds to the planet. They also brought water, helping Earth become the life-supporting planets it is today. Could the same thing happen on exoplanets?
Little Red Dots Eat Fast, But Not Faster Than Eddington
Little Red Dots are thought to be young supermassive black holes at the center of early galaxies. That would make them young versions of Active Galactic Nuclei. But Little Red Dots don't emit much x-ray light, and we're starting to learn why.

Rare Type of Black Hole Snacks on Star
Rare Type of Black Hole Snacks on Star
NASA’s Hubble Space Telescope and NASA’s Chandra X-ray Observatory teamed up to identify a new possible example of a rare class of black holes, identified by X-ray emission (in purple) in this image released on July 24, 2025. Called NGC 6099 HLX-1, this bright X-ray source seems to reside in a compact star cluster in a giant elliptical galaxy. These rare black holes are called intermediate-mass black holes (IMBHs) and weigh between a few hundred to a few 100,000 times the mass of our Sun.
Learn more about IMBHs and what studying them can tell us about the universe.
