Latest Observational astronomy Stories
A team of astronomers is working on a technique capable of detecting faint dust clouds around other stars where Earth-like planets could be hiding. This new technology could dramatically improve the odds of discovering planets with conditions suitable for life.
New data from NASA’s Chandra X-ray Observatory and NASA’s infrared Spitzer Space Telescope, has revealed that the early Universe may have contained more black holes than previously expected.
In an important milestone for the Thirty Meter Telescope (TMT) project, Japan, one of the project's five international partners, has indicated its strong national backing for the next-generation astronomical observatory.
The International Dark-Sky Association was recently awarded a grant from the Uwingu Fund in support of the organization's new program called "Save Our Stars."
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.
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.
Uwingu announced on Wednesday the launch of the world's first "Adopt-a-Planet" campaign, allowing the public an opportunity to adopt planets.
For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies.

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...
