Planets capable of supporting life could start out as gaseous worlds similar to Neptune, only to be transformed by the combination of two phenomena that individually can inhibit their potential habitability, University of Washington astronomers have discovered in a new study.

Astronomers have discovered the oldest known planetary system ever – a star that is more than 11 billion years old and orbited by at least five rocky planets that are all smaller than Earth.

Finding the next earth just got one step easier. A new NASA instrument designed to study dust in the so-called habitable zone around a star may help future missions centered around capturing images of planets similar to Earth.

One of the key factors in the search for life on other worlds is a planet’s ability to sustain liquid water, and researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) have for the first time revealed that this possibility exists on the type of planets known as super-Earths.

Provided by Dr. Robert Massey, Royal Astronomical Society Astronomers could soon be able to find rocky planets stretched out by the gravity of the stars they orbit, according to a group of researchers in the United States. The team, led by Prabal Saxena of George Mason University, describe how to detect these exotic worlds in a paper in the journal Monthly Notices of the Royal Astronomical Society. An artist’s impression of a stretched rocky planet in orbit around a red dwarf star....

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Sagan, Carl

Carl Edward Sagan (November 9, 1934 - December 20, 1996) was an American astronomer who pioneered exobiology and promoted the Search for Extraterrestrial Intelligence (SETI) and science in general. He is less well known for his skepticism. Born in Brooklyn, New York, Sagan attended the University of Chicago, where he received a bachelor's degree (1955) and a master's degree (1956) in physics, before earning his doctorate (1960) in astronomy and astrophysics. He taught at Harvard University...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...

Search for Extra-Terrestrial Intelligence (SETI) -- SETI (pronounced SEH-tee) stands for for Search for Extra-Terrestrial Intelligence. Interstellar travel is a common theme in science fiction stories, but the obstacles to such journeys are in practice enormous. An alternative approach to interstellar exploration is to survey the sky in hopes of finding transmissions from a civilization on a distant planet, but such an effort has obstacles as well. Overview Visiting another...

Radio Telescope -- In contrast to an ordinary telescope, which produces visible light images, a radio telescope "sees" radio waves emitted by radio sources located anywhere in the Universe, typically by means of a large parabolic ("dish") antenna, or arrays of them. The best-known (and largest) radio telescope is in Arecibo, Puerto Rico. A well-known radio telescope being an array of antennae is the Very Large Array (VLA) in Socorro, New Mexico. The largest (100-meter diameter) and most...
