GREENBELT, Md., March 10, 2015 /PRNewswire-USNewswire/ -- NASA has awarded the Mark IV and the Next Generation Very Long Baseline Interferometry Systems contract to the Massachusetts Institute
The South Pole Telescope is now ready for use in the search for black holes and will be joining its buddy, The Event Horizon Telescope.
The largest and most luminous black hole ever seen has been discovered, with a mass about 12 billion times that of the sun.
Reports published last year claiming to have detected evidence of gravitational waves emitted immediately following the Big Bang were inaccurate, new analysis of the data has revealed.
Someone dimmed the lights in space. Scientists observe a dimming quasar for the first time ever, and this could lead to a understanding of the mysterious black holes and their lifespans.
The intermittent light emitted by pulsars, the most precise timekeepers in the universe, allows scientists to verify Einstein's theory of relativity, especially when these objects are paired up with another neutron star or white dwarf that interferes with their gravity.
A team led by Damien Hutsemékers from the University of Liège in Belgium used the FORS instrument on the VLT to study 93 quasars that were known to form huge groupings spread over billions of light-years, seen at a time when the Universe was about one third of its current age.
In 1987 astronomers witnessed the violent death of a giant star in the form of a supernova, and now researchers have published results of their extensive ‘autopsy’ which yielded surprising results.
The first images captured with the Atacama Large Millimeter/submillimeter Array's new high-resolution capabilities have given researchers their best look ever at the process of planet formation around an infant star.

This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...
Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...
Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
Yakov Borisovich Zel'dovich (March 8, 1914 "“ December 2, 1987) was a productive Soviet physicist. He was instrumental in the advancement of Soviet nuclear and thermonuclear weapons, and also was an invaluable assistance in the fields of adsorption and catalysis, shock waves, nuclear physics, particle physics, astrophysics, physical cosmology, and general relativity. In 1914, he was born into a Jewish family in Minsk, now called Belarus. Four months after his birth, he and his family...
Radio Telescope -- In contrast to an ordinary telescope, which produces visible light images, a radio telescope "sees" radio waves emitted by radio sources located anywhere in the Universe, typically by means of a large parabolic ("dish") antenna, or arrays of them. The best-known (and largest) radio telescope is in Arecibo, Puerto Rico. A well-known radio telescope being an array of antennae is the Very Large Array (VLA) in Socorro, New Mexico. The largest (100-meter diameter) and most...
