Quasar Discovery Sets New Distance Record
An international team of astronomers has discovered the most distant quasar yet found — a cosmic monster more than 13 billion light-years from Earth powered by a supermassive black hole more than 1.6 billion times more massive than the Sun and more than 1,000 times brighter than our entire Milky Way Galaxy.
IMAGE RELEASE: A Blazar In the Early Universe
The supersharp radio “vision” of the National Science Foundation’s Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material ejected at three-quarters the speed of light from the core of a galaxy some 12.8 billion light-years from Earth.
VLA Sky Survey Reveals Newborn Jets in Distant Galaxies
Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys.
NRAO and GBO Saddened at Loss of Arecibo Telescope
The National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO) are saddened by the announcement of the decommissioning of the Arecibo Telescope in Puerto Rico due to recent and devastating structural damage.
IMAGE RELEASE: Galaxies in the Perseus Cluster
New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.
ALMA Shows Volcanic Impact on Io’s Atmosphere
New radio images from the Atacama Large Millimeter/submillimeter Array (ALMA) show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter’s moon Io.
ALMA Discovers Misaligned Rings in Planet-Forming Disk Around Triple Stars
Using the Atacama Large Millimeter/submillimeter Array (ALMA), two teams of astronomers have for the first time discovered a planet-forming disk with misaligned rings around a triple star system, called GW Orionis. The astronomers give two possible scenarios for the...
Radio Telescope is So Powerful it Can See the Surface of Other Worlds
Get ready for close-up surface images of distant planets in our solar system.
Next Generation VLA Endorsed by Canadian Panel
The Canadian Astronomy Long Range Plan 2020-2030, a report on priorities and recommendations for Canadian astronomy over the next decade, has recommended that Canada support the National Radio Astronomy Observatory’s (NRAO) proposed Next Generation Very Large Array (ngVLA), saying the new facility will enable transformational science across many areas of astrophysics.
This Insane Picture of The Moon Was Actually Taken From Earth
A test of a powerful new space imaging instrument has given us a gloriously detailed new perspective of the Apollo 15 Moon landing site.
Successful Test Paves Way for New Planetary Radar
The National Science Foundation’s Green Bank Observatory (GBO) and National Radio Astronomy Observatory (NRAO), and Raytheon Intelligence & Space conducted a test in November to prove that a new radio telescope system can capture high-resolution images in near-Earth space.
