redOrbit Staff & Wire Reports - Your Universe Online Astronomers have located a new terrestrial planet in a binary star system located roughly 3,000 light-years from Earth, according to new research appearing in the July 4 edition of the journal Science. Ohio State University professor Andrew Gould and four international teams of scientists used the technique of gravitational microlensing to discover the new planet, which is roughly twice the mass of Earth and orbits one of its...

In their quest to find solar systems analogous to ours, astronomers have determined how common our solar system is. They've concluded that about 15 percent of stars in the galaxy host systems of planets like our own, with several gas giant planets in the outer part of the solar system. "Now we know our place in the universe," said Ohio State University astronomer Scott Gaudi. "Solar systems like our own are not rare, but we're not in the majority, either." Gaudi reported the results of the...

Astronomers now have a new "eye" for determining the distance to certain mysterious bodies in and around our Milky Way galaxy. By taking advantage of the unique position of NASA's Spitzer's Space Telescope millions of miles from Earth, and a depth-perceiving trick called parallax, they were able to pin down the most probable location of one such object. The findings will ultimately help astronomers better understand the different components of our galaxy. "Forty years ago a visionary...

Though he couldn't be observed directly, the Invisible Man knew his presence could be betrayed by his effect on visible things. Employing a similar principle, a team led by Andrew Gould of Ohio State University will hunt for hard-to-see celestial objects, like black holes and dark matter, by observing how they affect light coming from stars behind them. This "gravitational lens" effect, predicted by Albert Einstein, has been observed repeatedly from the ground. But NASA's SIM PlanetQuest...

WASHINGTON (Reuters) - A cold, heavy "super-Earth" has been found orbiting a distant star, using a method that holds promise for detecting faraway planets that closely resemble our own, astronomers said on Monday. The planet weighs 13 times as much as Earth and is orbiting a star about 9,000 light-years away. But instead of circling close to its star, as Earth does, this "super-Earth" is about as distant from its star as Jupiter and Saturn are from the Sun. An international team of...

Cambridge, MA -- Astronomers have discovered a new "super-Earth" orbiting a red dwarf star located about 9,000 light-years away. This newfound world weighs about 13 times the mass of the Earth and is probably a mixture of rock and ice, with a diameter several times that of Earth. It orbits its star at about the distance of the asteroid belt in our solar system, 250 million miles out. Its distant location chills it to -330 degrees Fahrenheit, suggesting that although this world is similar in...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
