Latest Observational astronomy Stories
NASA’s Spitzer Space Telescope will celebrate its 10th anniversary of scientific research on Sunday, the US space agency announced on Friday.
Despite its remoteness and unique scientific work environment, the ALMA observatory in Chile is not immune to the disputes between workers and management that affect every other industry.
Astronomers have used a new type of telescope camera to capture the highest-resolution images of the night sky ever – answering some longstanding questions about planetary formation in the process.
Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable.
Astronomers say they have used the ALMA telescope to obtain a close-up view of material streaming away from a newborn star.
NASA's SOFIA observatory program manager Eddie Zavala reflects on the myriad details of preparing for and then executing the flying observatory's first Southern Hemisphere mission in the summer of 2013.
Las Cumbres Observatory Global Telescope (LCOGT), with first lights at nine new 1-meter telescopes since April of 2012, achieved another critical milestone by capturing the first on-sky image with a production Sinistro camera.
Understanding how the Milky Way formed is one of the central scientific questions in astronomy. Yet given the scale and complexity of the galaxy, there is a lot to consider.
Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time.

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...
