RIT professor co-authors Nature article and Gemini Observatory's 1,000th paper The discovery of 13 diffuse interstellar bands with the longest wavelengths to date could someday solve a 90-year-old mystery. Astronomers have identified the new bands using data collected by the Gemini North telescope of stars in the center of the Milky Way. Nature reports on its website today findings that support recent ideas about the presence of large, possibly carbon-based organic...

[ Watch the Video ] NASA's Fermi team recently released the second catalog of gamma-ray sources detected by their satellite's Large Area Telescope (LAT). Of the 1873 sources found, nearly 600 are complete mysteries. No one knows what they are. "Fermi sees gamma rays coming from directions in the sky where there are no obvious objects likely to produce gamma rays," says David Thompson, Fermi Deputy Project Scientist from Goddard Space Flight Center. Gamma rays are by their very nature...

[ Watch Video 1 ] | [ Watch Video 2 ] On Saturday 15 October, the European Southern Observatory (ESO) opened the doors of its headquarters in Garching bei München, Bavaria, Germany, to the public. Throughout the day, thousands of visitors had the chance to help build a full-size mock-up mirror of the largest planned telescope in the world – the European Extremely Large Telescope (E-ELT) – and to experience many other aspects of ESO´s work. Around 3100...

[ Watch the Video ] New VLT observations chart timeline of deionization Scientists have used ESO´s Very Large Telescope to probe the early Universe at several different times as it was becoming transparent to ultraviolet light. This brief but dramatic phase in cosmic history – known as deionization – occurred around 13 billion years ago. By carefully studying some of the most distant galaxies ever detected, the team has been able to establish a timeline for deionization...

For the first time, observations coordinated by ESA's space hazards team have found an asteroid that comes close enough to Earth to pose an impact threat. The space rock was found by amateur astronomers, highlighting the value of 'crowd-sourcing' to science and planetary defense. The discovery of asteroid 2011 SF108 was made by the volunteer Teide Observatory Tenerife Asteroid Survey (TOTAS) team during an observation slot sponsored by ESA's Space Situational Awareness (SSA) program in...

New Telescope Opens For Business In Chile's Atacama Desert

[ Watch the Video ] Astronomers have opened up its doors to a new ground-base telescope that will help give scientists a peak at the places that have never been explored. The Atacama Large Millimeter/submillimeter Array (ALMA) has released an image of a merging pair of galaxies as part of its grand opening. ALMA is the largest and most expensive radio observatory on Earth and was funded by several different space agencies. Radio observatories collect tiny waves given off by the...

A New Atlas Of The Milky Way

  Sino-German research group draws a new map at the Urumqi radio telescope and discovers two supernova remnants It may not be much use to hitchhikers through the galaxy, but it is extremely valuable to astronomers: the new radio atlas of the Milky Way. After almost ten years of work, researchers at the Max Planck Society and the Chinese Academy of Sciences have completed their investigation into the polarized radio emission in the galactic plane. The atlas is based on observations...

  NASA said on Wednesday that its Swift orbital telescope has captured a black hole ripping apart a star. Two studies appearing in the August 25th issue of the journal Nature show off a cosmic accident that has been streaming X-rays toward Earth since late March. The satellite first alerted astronomers of the intense and unusual high-energy flares from the new source of the constellation Draco. "Incredibly, this source is still producing X-rays and may remain bright enough...

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...
