Astronomers have studied a perplexing cosmic blast with a worldwide collection of telescopes, including ALMA and the VLA, but still are not sure exactly what it is.

ALMA is revealing new insights into the relationship between star-forming clouds and their host galaxies.

Using data from ALMA, a team of astronomers studied the growth and evolution of bubbles of hot plasma produced by active quasar HE 0515-4414. The bubble was analyzed by observing its effect on light from the cosmic microwave background. It is the first time this method was used to study quasar dynamics.

As comet 46P/Wirtanen neared Earth on December 2, astronomers using ALMA took a remarkably close look at its innermost regions.

ALMA has detected a star in a binary system that may have formed like a planet.

ALMA has conducted a survey of protoplanetary disks, the planet-forming dust belts around young stars.

New ALMA data reveal distinct streamers of material being pulled from three smaller galaxies into the larger galaxy W2246-0526, the most luminous known galaxy in the universe.

A billion light-years from Earth lies one of the universe’s most massive structures, a giant surrounded by a sprawling…

New ALMA images show never-before-seen surface details on Europa, including an enigmatic “cold spot.”

Using ALMA, an international team of astronomers found evidence that a white dwarf and a brown dwarf collided in a short-lived blaze of glory.
