New observations with the National Science Foundation’s Very Long Baseline Array radio telescope have deepened the mystery surrounding water molecules in a galaxy 65 million light- years away.
An extraordinary cosmic laboratory 21 million light-years away is providing radio astronomers their best opportunity yet to decipher the mysteries of the ultra-powerful engines at the hearts of many galaxies and quasars.
A VLA upgrade proposes an essentially new instrument, created from two existing instruments, with power and capability far exceeding that of either one alone.
Observations of Comet Hyakutake with the National Science Foundation’s millimeter-wave radio telescope in Arizona have revealed new information about our Solar System’s original material, including the first detection of the Carbonyl Sulfide molecule in a comet.
Do nearby stars have planetary systems like our own? How do such systems evolve? How common are such systems? Proposed radio observatories operating at millimeter wavelengths could start answering these questions within the next 6-10 years, according to scientists at the National Radio Astronomy Observatory.
Astronomers using the Very Large Array radio telescope have found some of the best evidence to date that small, new galaxies can form from material pulled out of older galaxies.
Astronomers using an international network of radio telescopes have produced a movie showing details of the expansion of debris from an exploding star.
In a technical feat thought impossible when Galileo was launched in 1989, the National Science Foundation’s Very Large Array will record the faint radio signal from the probe to help scientists measure the giant planet’s winds.
As scientists from the NRAO analyze a timelapse of powerful jets of material emerging from a double-star system 10,000 light-years away, new evidence from other research confirms that the source of the jets is a black hole.
Images made with the Very Long Baseline Array radio telescope show the mysterious X-ray nova in Scorpius as it ejected blobs of material at tremendous speeds over the period from August 18 to September 22, 1994.
