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

Lee Rannals for redOrbit.com — Your Universe Online 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. NASA said the best explanation is that the galaxy is shrouded in so much dust that the stars are completely hidden everywhere. As stars aged and burned out in the early universe, they filled interstellar space with dust as they lost their atmosphere. The quasar dates back to an...

2012-10-19 08:33:13

[ Watch the Video: Atomic Interferometer To Predict Gravitational Waves ] April Flowers for redOrbit.com - Your Universe Online NASA is pursuing a pioneering technology capable of atomic-level precision to detect gravitational waves or ripples in space-time caused by cataclysmic events, including the Big Bang itself. Researchers at NASA's Goddard Space Flight Center, AOSense, Inc and Stanford University have been awarded funding under NASA's Innovative Advanced Concepts (NIAC)...

Integral Space Observatory Celebrates Ten Years
2012-10-15 10:06:45

This week, ESA´s Integral space observatory celebrates ten years since launch on 17 October 2002. Integral, short for International Gamma-Ray Astrophysics Laboratory, is equipped with two gamma-ray telescopes, an X-ray monitor and an optical camera. All four of Integral´s instruments point simultaneously at the same region of the sky to make complementary observations of high-energy sources. Integral is often bathed in gamma-ray bursts, the death cries of massive stars that...

[ Watch the Video: X-ray Nova Reveals a New Black Hole in Our Galaxy ] Lee Rannals for redOrbit.com - Your Universe Online A new stellar-mass black hole has been discovered in our galaxy by NASA's Swift satellite. High-energy X-rays emanating from a source towards the center of our Milky Way galaxy were observed, indicating the presence of a previously unknown black hole. "Bright X-ray novae are so rare that they're essentially once-a-mission events and this is the first one...

2012-10-05 13:20:20

Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) is celebrating 50 years since it was founded on October 5, 1962. The signing of the ESO Convention and the founding of ESO was the culmination of the dream of leading astronomers from five European countries, including Belgium, France, Germany, the Netherlands and Sweden. These astronomers decided to join forces with the goal of building a large telescope that would give them great access to...

6-Hour Webcast For ESO’s 50th Anniversary With Live Very Large Telescope Observations
2012-09-29 10:00:24

On 5 October 2012, the European Southern Observatory (ESO) will broadcast A Day in the Life of ESO, a free, live event on the web, as part of its 50th Anniversary celebrations. There will be live observations from ESO´s flagship observatory, the Very Large Telescope (VLT), on Cerro Paranal in Chile´s Atacama Desert, as well as fascinating talks from astronomers at ESO´s Headquarters in Germany. Members of the public are invited to ask questions in advance of the event, or...

New Comet Discovery May Be Brightest Visitor In Past Hundred Years

Lawrence LeBlond for redOrbit.com - Your Universe Online Hale-Bopp, Haley´s, McNaught. These are just a few of the more well-known modern comets that have blazed across the night sky in our lifetime. Another comet that has been recently discovered could be added to that list next year when it makes a pass by the Sun in late 2013. The comet, named C/2012 S1 (ISON), is due to come within 1.1 million miles of the Sun on, or around, November 29, 2013. Vitali Nevski and Artyom...

Ancient Starlight Recorded By Dark Energy Camera
2012-09-18 04:19:18

April Flowers for redOrbit.com - Your Universe Online Approximately 8 billion years ago, the light from distant galaxies began streaming towards Earth. Now, at a mountaintop observatory in Chile, the newly constructed Dark Energy Camera (DECam), the most powerful sky-mapping machine ever created, has captured that ancient starlight and recorded it for the first time. Early on September 12, 2012, the DECam, mounted atop the Victor Blanco Telescope at the Cerro Tololo Inter-American...

Planets Can Form In The Center Of Violent, Unstable Galaxies

April Flowers for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. The center of the Milky Way seems like the last place to form a new planet, inhospitable and violent even. Stars crowd each other, whizzing through space like cars on a rush hour freeway while supernova explosions blast out shock waves and bathe the region in intense...

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...
