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.
A dense whirling mass orbiting what almost certainly is a black hole of truly Brobdingnagian proportions has been discovered at the heart of an active galaxy some 21 million light years from Earth.
Researchers using the Very Large Array have discovered that a small, powerful object in our own cosmic neighborhood is shooting out material at nearly the speed of light — a feat previously known to be performed only by the massive cores of entire galaxies.
