Early disk galaxy found by ALMA is hard to explain

Disk galaxies like our own Milky Way grew faster than most astronomers expected. That’s the surprising conclusion of a new ALMA discovery. After the Big Bang, some 13.8 billion years ago, atoms first clumped together into small, irregular galaxies. These ‘galactic building blocks’ later merged intolarger and larger systems....

ALMA helps discover strange sideways structure in distant black hole jet

Astronomers have obtained the sharpest image ever of the powerful jet of material from a giantblack hole, and they made a surprising discovery.Black holes are regions in space with so much gravity that they gobble up everything in theirneighborhood. Almost all of the gas is falling into the black...
