WASHINGTON, April 16, 2013 /PRNewswire-USNewswire/ -- Researchers using the airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured the most detailed mid-infrared images yet of a massive star condensing within a dense cocoon of dust and gas. (Logo - http://photos.prnewswire.com/prnh/20081007/38461LOGO) The star is G35.20-0.74, commonly known as G35. It is one of the most massive known protostars and is located relatively close to Earth at a distance of 8,000...

Big Bang In High Fidelity Sound
2013-04-10 10:53:15

[ Watch the Video: The Sounds of the Big Bang in High Fidelity ] April Flowers for redOrbit.com - Your Universe Online "If the Universe started with a bang, and no one was alive yet to observe it, would it still make a sound?" It sounds like the start of a really cliché joke, but the answer, surprisingly, is yes. Scientists believe the expanding early Universe produced waves of sound that echoed through the dense plasma and hydrogen that filled it at the time....

International Dark Sky Week
2013-04-06 05:30:50

Lee Rannals for redOrbit.com - Your Universe Online International Dark Sky Week (IDSW) is kicking off this weekend in an attempt to show the world just how dark our skies can be without light pollution. The International Dark-Sky Association´s (IDA) week long festivities began on April 5 and continue through April 11. The week is designed to promote ways to help put a dent in light pollution, such as directing light downward instead of up towards the sky, which washes out the stars...

New Light Shed On The Earliest Moments Of The Universe Using New Radio Telescope
2013-03-27 10:47:16

Square Kilometre Array (SKA) Africa In the week that saw the release of the first results from the European Space Agency's Planck satellite, astronomers at the Hartebeesthoek Radio Astronomy Observatory (HartRAO) near Johannesburg are working on a new radio telescope that will also shed new light on the very earliest moments of universe. The C-Band All-Sky Survey (C-BASS) is a project to map the sky in microwave (short-wavelength radio) radiation. Like Planck, it will survey the whole...

Black Hole And Red Dwarf Intertwined In 2-Hour Tango Of Death
2013-03-19 18:35:43

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using ground and space telescopes around the world have revealed a black hole and a star, intertwined in a cosmic tango together. Astronomers writing in Astronomy & Astrophysics say they have observed a black hole, known as MAXI J1659-152, and a red dwarf with a mass only 20 percent that of the Sun orbiting each other every 2.4 hours. The two cosmic bodies sit over half a million miles away from each other, but...

Project 1640 Imaging System Allows Astronomers To See Distant Exoplanets
2013-03-13 21:39:14

Brett Smith for redOrbit.com — Your Universe Online Using a state-of-the-art telescopic imaging system, astronomers are now able to see planets that orbit distant stars, known as exoplanets, more easily and in greater detail, according to a report in the Astrophysical Journal. Scientists gather information from distant planets via the light they radiate, referred to as their spectra, and previously, astronomers have only been able to analyze planets as they pass in front of, or...

Revolutionary Telescope Will Enable Unprecedented Views Of The Cosmos
2013-03-13 14:29:02

ESO [ Watch The Video Scenes from the ALMA Inauguration day ] Today, in a remote part of the Chilean Andes, the Atacama Large Millimeter/submillimeter Array (ALMA), was inaugurated at an official ceremony. This event marks the completion of all the major systems of the giant telescope and the formal transition from a construction project to a fully fledged observatory. ALMA is a partnership between Europe, North America and East Asia in cooperation with the Republic of Chile....

Closest Star System In A Century Found 6.5 Light Years Away
2013-03-11 16:28:34

Brett Smith for redOrbit.com - Your Universe Online Using data obtained from a NASA satellite, a Pennsylvania State University astronomer has identified the closest solar system to be found within the past 97 years. According to astronomer Kevin Luhman´s report in the Astrophysical Journal Letters, the newly identified system is a pair of brown dwarf stars and the third-closest system to the Sun. “The distance to this brown dwarf pair is 6.5 light years -- so close that...

Virtual Press Conference To Be Held For ALMA Inauguration
2013-03-06 08:33:42

ESO On 13 March 2013 the Atacama Large Millimeter/submillimeter Array (ALMA), the largest astronomical project in the world, will be inaugurated in Chile, celebrating ALMA´s transition from a construction project to a fully fledged observatory. For members of the media who cannot be present at the inaugural event, the ALMA partner organizations will host an online press meeting via Adobe Connect on 12 March 2013 at 12:00 CET. Presentations about the development, inauguration and...

Giants Like Jupiter May Have Formed In The Gas Disk Of Young Stars
2013-03-06 06:18:35

Lawrence LeBlond for redOrbit.com - Your Universe Online New research from Carnegie Institution for Science looks at how gas giants similar to Jupiter and Saturn formed and evolved. Using theoretical modeling, lead researcher Alan Boss provides clues that gas giants may form in the presence of gas disks that surround stars in their infancy. The work was recently published in the Astrophysical Journal. By observing young stars that are surrounded by gas disks, Boss demonstrated that...

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...
