Earth-like Planets May Be Scarce In Systems With Hot Jupiters
2012-05-08 12:54:38

Solar systems that have “hot Jupiter-type” planets closely orbiting host stars likely do not have Earth-like planets neighboring them, according to a new study by researchers from University of Florida (UF), Fermilab, and Carnegie Institution. “Hot Jupiters” are giant planets that are roughly the size of Jupiter but orbit more closely to their parent stars, making them much hotter than Earth or Jupiter, according to Eric Ford, researcher at UF. These planets have...

Reports Confirm Existence Of Habitable Exo-Planet
2012-04-28 03:28:20

After re-evaluating information collected back in February, scientists reportedly confirmed on Friday that they had indeed discovered a planet outside of our solar system that is capable of supporting life. The planet, which was been dubbed Gliese 667Cc, orbits around a red dwarf star located 22 light years away from Earth, according to published reports from the Telegraph. Scientists told the newspaper that Gliese 667Cc lies in what they refer to as the "habitable zone," which means that...

Super-Earth Transfer Of Life Unlikely
2012-03-22 04:04:10

While scientists believe conditions suitable for life might exist on the so-called "super-Earth" in the Gliese 581 system, it's unlikely to be transferred to other planets within that solar system. "One of the big scientific questions is how did life get started and how did it spread through the universe," said Jay Melosh, distinguished professor of earth and atmospheric sciences. "That question used to be limited to just the Earth, but we now know in our solar system there is a lot of...

Leading Exoplanet Hunters Awarded Science Prize

Winners are the astronomers behind La Silla´s world-leading HARPS instrument World-renowned Swiss astronomers Michel Mayor and Didier Queloz of the Geneva Observatory have been awarded the 2011 BBVA Foundation Frontiers of Knowledge Award in Basic Sciences for their work on exoplanets. The foundation recognized their groundbreaking efforts in developing “new astronomical instruments and experimental techniques that led to the observation of planets outside the solar...

An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed. Their work will be published by the Astrophysical Journal...

Image 1 - Microlensing Survey Finds A Multitude Of Planets
2012-01-12 03:54:16

[ Watch the Video ] Planets around stars are the rule rather than the exception An international team, including three astronomers from the European Southern Observatory (ESO), has used the technique of gravitational microlensing to measure how common planets are in the Milky Way. After a six-year search that surveyed millions of stars, the team concludes that planets around stars are the rule rather than the exception. The results will appear in the journal Nature on 12 January 2012....

Astronomers Launch Online Database Of Habitable Planets
2011-12-06 05:02:07

Only 15 planets and 30 moons could potentially support alien life, according to a new online catalog of habitable planets launched by astronomers on Monday. The Habitable Exoplanets Catalog (HEC) website describes the project as "an online database for scientists, educators, and the general public focused on habitable exoplanets discoveries." "The catalog uses various habitability indices and classifications to identify, rank, and compare exoplanets, including their potential...

Forming Planet Captured By Astronomer
2011-10-20 10:34:22

A University of Hawaii astronomer is credited with capturing the first direct image of a planet in the process of being formed around its star, reports the Associated Press (AP). Astronomer Adam Kraus, from UH at Manoa, made the discovery using the twin 10-meter Keck telescopes on Mauna Kea. He also used mirrors to cancel out starlight to view the phenomenon, a technique called aperture mask interferometry. It is usually impossible to capture such planetary births because the parent...

Distant Planet Blasted With X-rays From Nearby Star
2011-09-14 05:56:33

  A nearby star is pummeling a companion planet with a barrage of X-rays 100,000 times more intense than the Earth receives from the sun. New data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope suggest that high-energy radiation is evaporating about 5 million tons of matter from the planet every second. This result gives insight into the difficult survival path for some planets. The planet, known as CoRoT-2b, has a mass about...

Image 1 - HARPS Finds Fifty New Exoplanets
2011-09-12 12:45:58

  Richest haul of planets so far includes 16 new super-Earths [ View Video ] Astronomers using ESO´s world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star. By studying the properties of all the HARPS planets found so far, the team has found that about 40% of stars similar to the Sun have at least one planet lighter than Saturn. The...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...

Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...

La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...
