Nearby Earth-like planet found: Gliese 832c

Nearby Earth-like planet found: Gliese 832c

A University of New South Wale (UNSW)-led team of researchers has discovered a potentially habitable Earth-like planet that is only 16 light years away. An artist’s impression of the new planet and Earth.

Earth's "Twin" Discovered, But Does it Host Life?

Earth’s “Twin” Discovered, But Does it Host Life?

  Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-sized planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable [continue reading]

An Exoplanet Discovered That Shouldn't Be There

An Exoplanet Discovered That Shouldn’t Be There

  The discovery of a giant planet orbiting its star at 650 times the average Earth-Sun distance has astronomers puzzled over how such a strange system came to be. This is an artist’s conception of a young planet in a distant orbit around its host star. The star still harbors a debris disk, remnant material [continue reading]

Signatures of Water on Five Hazy Exoplanets Found

Signatures of Water on Five Hazy Exoplanets Found

  Using the powerful eye of NASA’s Hubble Space Telescope, two teams of scientists have found faint signatures of water in the atmospheres of five distant planets. NASA scientists found faint signatures of water in the atmospheres of five distant planets orbiting three different stars. All five planets appear to be hazy. This illustration shows a star’s light [continue reading]

New Models Aid the Search for Earth-Like Planets

New Models Aid the Search for Earth-Like Planets

  Researchers from Bern have developed a method to simplify the search for Earth-like planets: By using new theoretical models they rule out the possibility of Earth-like conditions, and therefore life, on certain planets outside our Solar System – and limit their search by doing so. An artist’s perception of the planet Kepler-22b, discovered by the Kepler Space Telescope. [continue reading]

Inhabitable Exoplanets Might be Unveiled by New Tool

Inhabitable Exoplanets Might be Unveiled by New Tool

  Funding for SPIRou, a spectropolarimeter and a high-precision velocimeter optimized for both the detection of habitable Earth twins orbiting around nearby red dwarf stars and the study of the formation of Sun-like stars and their planets, was confirmed Monday November 4, 2013 by the Canada-France-Hawaii Telescope (CFHT) observatory. University of Montreal and France’s Institut [continue reading]
