Radio Astronomy in the News
The National Science Foundation has provided funding to repair damage to the Very Long Baseline Array station on St. Croix caused by Hurricane Maria in 2017.
Astronomers have used the VLA to detect a possible planetary-mass object with a surprisingly powerful magnetic field some 20 light-years from Earth. It can help scientists better understand magnetic processes on stars and planets.
Astronomers have made the first definitive detection of a radioactive molecule in interstellar space: a form, or isotopologue of aluminum monofluoride. The new data reveal that this radioactive isotopologue was created by the collision of two stars, a tremendously rare cosmic event that was witnessed on Earth as a “new star,” or nova, in the year 1670.
Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
Image of the Week:
Across the Milky Way (teal version)A radio and infrared wave panorama of a section of the Milky Way in the constellations of Scutum and Aquila. Normal stars show up as the myriad of aqua-white points. Radiation from the newborn stars heats surrounding dust into infrared temperatures (in teal), while the ultraviolet light from these stars separates electrons from hydrogen atoms, and gives off radio waves (in red). More mature stars have destroyed nearby dust, leaving red cores surrounded by pink, then teal, shells as the temperature drops far from the stars. Massive stars have died in titanic explosions and blasted their gas light years into space at thousands of miles per second, leaving blast arcs (in red). The diffuse infrared glow (teal) comes from the tiny dust particles scattered through space.
