Latest Observational astronomy Stories
Two identical FLOYDS spectrographs, installed in recent weeks at telescopes 6,000 miles apart, robotically acquired a supernovae target this week.
The International Dark-Sky Association and Loch Ness Productions are giving attendees of the International Astronomical Union Congress in Beijing a sneak peak of a full dome video on light pollution called "Losing the Dark."
Associated Universities Inc. (AUI) and the National Radio Astronomy Observatory (NRAO) have made a preliminary examination of the report released today from the National Science Foundation (NSF) Astronomy Portfolio Review Committee (PRC).
The largest-ever 3-D map of massive galaxies and distant black holes was released this week in the hopes that it will help explain the mysteries of "dark matter" and "dark energy."
Light pollution has been a growing problem recently, and as skylines continue to grow, the night sky becomes dimmer and dimmer. A new shift is taking place in lighting though, and researchers estimate that the color of the night sky may be changing as well.
Led by Berkeley Lab scientists, the Sloan Digital Sky Survey’s BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure
Astronomers have identified an X-ray signal that followed an observation made last year of a quiescent black hole in a distant galaxy. The black hole discovered by the team last year was seen erupting after shredding and consuming a passing star.
While some find it as the source of inspiration for wrapping gifts, Scotch tape inspired one scientist at NASA to build a special X-ray mirror.
Researchers announced Friday that they had successfully achieved "first light" at low frequencies using the Jansky Very Large Array (JVLA) radio astronomy telescope.

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...
