ALMA dives into black hole's 'sphere of influence'

What happens inside a black hole stays inside a black hole, but what happens inside a black hole's "sphere of influence"—the innermost region of a galaxy where a black hole's gravity is the dominant force—is of intense ...

As clouds fall apart, a new star is born

Using the ALMA observatory in Chile, a group of astronomers led by MPIA's Henrik Beuther has made the most detailed observation yet of the way that a giant gas cloud fragments into dense cores, which then act as the birthplaces ...

Revealing the black hole at the heart of the galaxy

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* at the center of the galaxy comes from a smaller region ...

ALMA gives passing comet its close-up

As comet 46P/Wirtanen neared Earth on December 2, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a remarkably close look the innermost regions of the comet's coma, the gaseous envelope around ...

Black hole 'donuts' are actually 'fountains'

Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut ...

First high-resolution look at the quiet Sun with ALMA at 3 mm

Observations of the radio continuum at millimeter (mm) wavelengths provide a unique chromospheric diagnostic. The quiet sun mm-wavelength emission mechanism is free-free and electrons are almost always in local thermodynamic ...
