Distant Quasar Shows No Sign Of Feeding On Galaxy Of Stars
2012-10-24 12:05:36

While looking at one of the most distant quasars in the universe, astronomers were surprised to not see an underlying host galaxy of stars feeding it.

Dead Stars Could Guide Future Spacecraft

The European Space Agency (ESA) has commissioned researchers to investigate the use of dead stars to navigate in deep space. If it is found to be possible, this technique could revolutionize the way spacecraft navigate in the outer Solar System and beyond.

Pulsar Speed And Rotation Explained By New Model
2012-10-09 14:38:04

A new model developed by researchers at the University of Southampton explains how the spin of a pulsar slows down as the star gets older.

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. 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...

upstander
  • A person who stands up for something, as contrasted to a bystander who remains inactive.
  • One of the upright handlebars on a traditional Inuit sled.
The word 'upstander' in the first sense here is a play on the word 'bystander' and the idea of 'standing up' for something.
