Gas ‘Waterfalls’ Reveal Infant Planets around Young Star

National Radio Astronomy Observatory

For the first time, astronomers using ALMA have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into gaps that are most likely caused by planets in formation. These gas flows have long been predicted and would directly influence the chemical composition of planet atmospheres. This research is published in the latest issue of the journal Nature.

Newswise: Going Against the Flow Around a Supermassive Black Hole

Going Against the Flow Around a Supermassive Black Hole

National Radio Astronomy Observatory

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe. “Thanks to the spectacular resolution of ALMA, we measured the movement of gas in the inner orbits around the black hole,” explains Violette Impellizzeri of the National Radio Astronomy Observatory (NRAO), working at ALMA in Chile and lead author on a paper published in the Astrophysical Journal. “Surprisingly, we found two disks of gas rotating in opposite directions.”

Towering Balloon-like Features Discovered near Center of the Milky Way

National Radio Astronomy Observatory

An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way – a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the central region of our galaxy. This hourglass-like feature, which dwarfs all other radio structures in the galactic center, is likely the result of a phenomenally energetic burst that erupted near the Milky Way’s supermassive black hole a few million years ago.

ALMA Shows What’s Inside Jupiter’s Storms

National Radio Astronomy Observatory

New radio wave images made with the Atacama Large Millimeter/submillimeter Array (ALMA) provide a unique view of Jupiter’s atmosphere down to fifty kilometers below the planet’s visible (ammonia) cloud deck.

ALMA Dives into Black Hole’s ‘Sphere of Influence’

National Radio Astronomy Observatory

New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) provide an unprecedented close-up view of a swirling disk of cold interstellar gas rotating around a supermassive black hole.

Planetary Rings of Uranus ‘Glow’ in Cold Light

National Radio Astronomy Observatory

Summary: Using the both ALMA and the VLT, astronomers have imaged the cold, rock-strewn rings encircling the planet Uranus. Rather than observing the reflected sunlight from these rings, ALMA and the VLT imaged the millimeter and mid-infrared “glow” naturally emitted by the frigidly cold particles of the rings themselves.

Black Hole's Tug on Space Pulls Fast-Moving Jets in Rapid Wobble

National Radio Astronomy Observatory

A spinning black hole pulls in material from a companion star, and its gravitational effect causes ejected jets of material to wobble like a child's spinning top.
