Image 1 - RXTE Captures Thermonuclear Behavior Of Unique Neutron Star
2012-03-11 07:04:11

A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. In October 2010, a neutron star near the center of our galaxy erupted with hundreds of X-ray bursts that were powered by a barrage of thermonuclear explosions on the star's surface. NASA's Rossi X-ray Timing Explorer (RXTE) captured the month-long fusillade in extreme detail. Using this data, an international team of...

Image 1 - Earth's Reflection From Moon Helps Search For Life Outside Our Solar System
2012-03-01 05:28:12

[ Video 1 ] | [ Video 2 ] An international team of astronomers has found evidence of life in the Universe — right here on Earth — after pointing one of the world´s largest telescope at the Moon.  While the observation might seem trivial, it has helped perfect a technique that could lead to future discoveries of life outside our solar system. The researchers used the European Southern Observatory´s Very Large Telescope (VLT) to look at Earthshine reflected from...

Image 1 - APEX Images Cosmic Dust Filament Light-years Long

[ Video 1 ] | [ Video 2 ] Star formation in “dark markings of the sky” A new image from the APEX (Atacama Pathfinder Experiment) telescope in Chile shows a sinuous filament of cosmic dust more than ten light-years long. In it, newborn stars are hidden, and dense clouds of gas are on the verge of collapsing to form yet more stars. It is one of the regions of star formation closest to us. The cosmic dust grains are so cold that observations at wavelengths of around one...

Twenty-six educators from the United States have been selected for research flights aboard SOFIA, NASA's Stratospheric Observatory for Infrared Astronomy. As participants in the Airborne Astronomy Ambassadors program, the educators will partner with professional astronomers using SOFIA for scientific observations in 2012 and 2013. SOFIA is a modified Boeing 747SP jetliner equipped with a 100-inch (2.5-meter) diameter telescope. The observatory enables the analysis of infrared light to...

What Color Is The Milky Way?
2012-01-12 11:04:45

Astronomers from University of Pittsburgh seeking to find the true color of our very own Milky Way have revealed that it is so white that it would resemble a fresh blanket of snow to the naked eye. The astronomers said the color of the galaxy is important because it reveals age, ranging from young blue galaxies with new stars still being born, to older red ones that rarely form new stars. It seems we are right in the middle of this range. The Pittsburgh University team wanted to find...

Image 1 - Fermi Explores New Energy Extremes
2012-01-11 04:12:57

After more than three years in space, NASA's Fermi Gamma-ray Space Telescope is extending its view of the high-energy sky into a largely unexplored electromagnetic range. On Tuesday, the Fermi team announced its first census of energy sources in this new realm. Fermi's Large Area Telescope (LAT) scans the entire sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form of light. While the energy of visible light falls between about 2 and 3...

[ Watch the Video ] Using observations from NASA's Rossi X-ray Timing Explorer (RXTE) satellite and the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) radio telescope, an international team of astronomers has identified the moment when a black hole in our galaxy launched super-fast knots of gas into space. Racing outward at about one-quarter the speed of light, these "bullets" of ionized gas are thought to arise from a region located just outside the black hole's...

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...

A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...

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...

The Reverend Thomas William Webb (December 14, 1807 "“ May 19, 1885) was a British astronomer and faithful clergyman. The lone son of a clergyman, the Rev. John Webb was raised and educated by his father in absence of his mother who died in Webb's early childhood. He travelled to Oxford to attend Magdalen College. Soon after, he was ordained a minister by the Anglican Church in 1829. In 1843, he married Henrietta Montague. Mrs. Webb died on September 7, 1884. Webb followed shortly...
