New US & Japan Partnership Will Make the World’s Most Powerful Telescope Even More Sensitive
Nov 14, 2023
The National Science Foundation’s National Radio Astronomy Observatory (NRAO) and the National Astronomical Observatory of Japan (NAOJ) are joining efforts to expand the capabilities of the world’s most powerful millimeter/ submillimeter telescope, the Atacama Large Millimeter/submillimeter Array (ALMA).
How Radio Astronomy Sees Magnetic Fields
Sep 21, 2023
When magnetic fields are extremely strong, charged particles caught in these fields can be accelerated to incredible speeds. As they accelerate around the magnetic field, the charges can emit light directly. It’s known as synchrotron radiation, and it’s often seen coming from the heated accretion disks of black holes.
A Surprise Chemical Find by ALMA May Help Detect and Confirm Protoplanets
Jun 30, 2023
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of protoplanets. The discovery will provide astronomers with an alternate method for detecting and characterizing protoplanets when direct observations or imaging are not possible.
