Provided by Richard Hook, ESO Quasars are galaxies with very active supermassive black holes at their centers. These black holes are surrounded by spinning discs of extremely hot material that is often spewed out in long jets along their axes...

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.
CHARLOTTESVILLE, Va., Nov.
Imagine how brightly our Sun shines on a warm summer day. Now, try to imagine a star approximately 10 million times brighter. A team of astronomers have discovered such a pulsating star.
A new study has found that massive black holes which emit radio-frequency-emitting particles at near-light speed may possibly be able to block the formation of new stars in older galaxies.
The Nuclear Spectroscopic Telescope Array, or NuSTAR, recently spotted the brightest pulsar ever recorded using X-ray optics designed by a team that included researchers from the Lawrence Livermore
Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns.
As one team of experts has published a study claiming to have discovered hints of gravitational waves in stars, another has released a new galactic dust map that casts doubts on previous research claiming to have detected such waves earlier this year.
New work from Carnegie’s Hubble Fellow Yue Shen and Luis Ho of the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University solves a quasar mystery that astronomers have been puzzling over for 20 years.
New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built.

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...
