Galaxies Discovered Buried In Dust
2013-06-01 05:33:58

redOrbit Staff & Wire Reports - Your Universe Online Approximately 80 percent of all unidentifiable millimeter wave signals emitted in the universe actually originate from galaxies, according to new research published in Saturday´s edition of the Astrophysical Journal Letters. Based on observations collected using Atacama Large Millimeter/sub-millimeter Array (ALMA) telescopes, professor Kouji Ohta and postdoctoral researcher Bunyo Hatsukade of Kyoto University in Japan and...

Planetary Dance In The Sunset Sky
2013-05-24 04:15:11

[ Watch the Video: ScienceCasts: Sunset Triangle ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Fans of stargazing are in for a treat this weekend. Over the next several days the planets, Venus, Jupiter, and Mercury will approach each other in the fading sunlight to form a triple conjunction — where three bodies appear to converge in the sky. The events will culminate on the evening of the 26th, and will appear to form a triangle just above the horizon....

Uwingu Kicking Off 'Adopt-A-Planet' Campaign
2013-05-02 17:53:25

Lee Rannals for redOrbit.com — Your Universe Online Uwingu announced on Wednesday the launch of the world's first "Adopt-a-Planet" campaign, allowing the public an opportunity to adopt planets. The space company's new open-ended campaign allows the public to adopt exoplanets in astronomical databases through Uwingu's website. The campaign coincides with its other campaign aimed at naming a planet. Uwingu has asked participants to vote on names for exoplanets, which costs money....

Pinpointing Radio Wave Origins In The Distant Universe
2013-05-01 05:04:41

April Flowers for redOrbit.com - Your Universe Online For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies. This was achieved by more than 50 hours of observations with the ultra-sensitive Karl G. Jansky Very Large Array (VLA). The researchers found that approximately 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores. The remaining 37 percent...

New Android App Gathers Light Pollution Data For Scientists
2013-04-29 18:58:49

Lee Rannals for redOrbit.com — Your Universe Online Researchers have developed an app for smartphones powered by Google's Android operating system capable of measuring night sky brightness. The new application, called "Loss of the Night," will gather data so scientists can better understand light pollution on a worldwide scale. "In natural areas you can see several thousand stars with the naked eye" says Dr. Christopher Kyba, physicist at the Freie Universität....

Slooh To Broadcast Saturn Show This Weekend
2013-04-25 19:06:02

[ Watch the Video: ScienceCasts: Saturn Close Up ] Lee Rannals for redOrbit.com — Your Universe Online This weekend, stargazers should dust-off their telescopes and catch a glimpse of Saturn at its best and brightest. On Sunday, April 28th, Saturn will be making its closest approach to Earth, appearing bigger and brighter than at any other time in 2013. Astronomers refer to this event as "an opposition," because Saturn will be opposite the sun in the skies of Earth. The...

Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Lee Rannals for redOrbit.com — Your Universe Online Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old. The team wrote in the journal Nature that HFLS3 sits at about 12.8 billion light-years from Earth. They said the distant galaxy is producing about 3,000 Suns per year, which is more than 2,000 times that of our own Milky Way galaxy. "This is the...

Early Star Forming Galaxies
2013-04-17 05:09:48

Lee Rannals for redOrbit.com - Your Universe Online Astronomers report in The Astrophysical Journal that they have determined the positions of over 100 of the most fertile star-forming galaxies in the early Universe. The group used the new Atacama Large Millimeter/submillimeter Array (ALMA) telescope during their observations. This telescope can capture just as many observations of this group of galaxies in just a few hours as similar telescopes can in more than a decade. [ Video:...

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...

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...
