New ALMA observation uncover compelling evidence that two planets orbit young star.

Astronomers studying a cluster of still-forming protogalaxies seen as they were more than 10 billion years ago have found that a giant galaxy in the center of the cluster is forming from a surprisingly-dense soup of molecular gas.

Glancing collision produces galactic “eyelids.”

Astronomers using the super-sharp radio vision of the National Science Foundation’s Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy’s nearly-naked supermassive black hole to emerge and speed away at more than 2,000 miles per second.

For the first time, astronomers have seen a dusty disk of material around a young star fragmenting into a multiple-star system.
