Going Against the Flow Around a Supermassive Black Hole
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.”

New research sheds light on the ages of lunar ice deposits
The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study suggests…
Pressure runs high at edge of solar system
Out at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists…
Scientists observe year-long plateaus in decline of type Ia supernova light curves
This is a surprising finding as astronomers had expected that the light curve would not only continue decreasing but even experience a sharp drop, rather than flattening into a plateau. The discovery is a huge step forward for astronomers as…

A dusty lab in the sky
Joe Nuth loves dust. Among astronomers, that puts him in a minority. “The traditional astronomers — the people looking at galaxies and stars — they hate dust,” said Nuth, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt,…
The American Institute of Physics Announces 2019 Science Communication Award Winners
