- A very bright black hole shines in deep space.
- The black hole is active and sends radiation outward.
- Its strong radiation can reach nearby galaxies far away.
- Nearby galaxies show less new star formation than usual.
- Radiation and heat can break cold gas in clouds.
- Cold gas is the fuel that makes new stars.
- Breaking the gas stops star birth for some time.
- Scientists use telescopes to study galaxy systems nearby now.

When a Star Is Torn Apart by a Black Hole
A new study explains how a star that wanders too close to a supermassive black hole is stretched into a thin debris stream. Collisions and later accretion make bright flares called tidal disruption events (TDEs), which simulations now model in detail.
Astronomers image two collisions at Fomalhaut
Astronomers imaged the dusty aftermath of two collisions between large bodies around the nearby young star Fomalhaut, the first such images beyond the solar system. Teams will track the expanding dust with Hubble and the James Webb Space Telescope.
New models rethink the insides of Uranus and Neptune
A University of Zurich team created new interior models for Uranus and Neptune. The work shows the planets could be rock-rich or water-rich, helps explain their odd magnetic fields, and says we need dedicated missions to learn more.
