Astronomers have found a giant magnetic loop stretched outward from one of the stars making up the famous double-star system Algol. The scientists used an international collection of radio telescopes to discover the feature, which may help explain details of previous observations of the stellar system.
Astronomers Get New Tools for Gravitational-Wave Detection
Teamwork between gamma-ray and radio astronomers has produced a breakthrough in finding natural cosmic tools needed to make the first direct detections of the long-elusive gravitational waves predicted by Albert Einstein nearly a century ago.
Giant Intergalactic Gas Stream Longer than Thought
A giant stream of gas flowing from neighbor galaxies around our own Milky Way is much longer and older than previously thought, astronomers have discovered.
Record-Breaking Precision Radio Astronomy
Astronomers will tie together the largest collection of the world’s radio telescopes ever assembled to work as a single observing tool in a project aimed at improving the precision of the reference frame scientists use to measure positions in the sky.
Blast from the Past Gives Clues About Early Universe
Astronomers using the National Science Foundation’s Very Large Array radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe — a gigantic stellar explosion known as a Gamma Ray Burst.
Student Discovers Strange Astronomical Object
A West Virginia high-school student analyzing data from a giant radio telescope has discovered a new astronomical object — a strange type of neutron star called a rotating radio transient.
