Latest Observational astronomy Stories
This weekend, stargazers should dust-off their telescopes and catch a glimpse of Saturn at its best and brightest.
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.
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.
"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.
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.
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.
Astronomers using ground and space telescopes around the world have revealed a black hole and a star, intertwined in a cosmic tango together.
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.
Today, in a remote part of the Chilean Andes, the Atacama Large Millimeter/submillimeter Array (ALMA), was inaugurated at an official ceremony.

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...
