Kepler-421b
2014-07-22 05:09:31

April Flowers for redOrbit.com - Your Universe Online The time that it takes for a planet, or planetary satellite, to orbit its star is considered the planet's year. For example, Earth's year is approximately 365 days, while Mercury's is 88 days and Mar's year is 687 days long. A group of astronomers working at the Harvard-Smithsonian Center for Astrophysics (CfA) has discovered a transiting exoplanet, named Kepler 421b, with the longest known year of any of the 1,800 exoplanets...

Exoplanets Come In Three "Neapolitan" Flavors
2014-06-02 03:09:48

Harvard-Smithsonian Center for Astrophysics The planets of our solar system come in two basic flavors, like vanilla and chocolate ice cream. We have small, rocky terrestrials like Earth and Mars, and large gas giants like Neptune and Jupiter. We're missing the astronomical equivalent of strawberry ice cream - planets between about one and four times the size of Earth. NASA's Kepler mission has discovered that these types of planets are very common around other stars. New research...

Kepler Space Telescope Marks Five Years in Space
2014-03-07 11:47:49

NASA's Jet Propulsion Laboratory Exactly five years ago, on March 6, 2009, NASA's Kepler Space Telescope rocketed into the night skies above Cape Canaveral Air Force Station in Florida to find planets around other stars, called exoplanets, in search of potentially habitable worlds. Since then, Kepler has unveiled a whole new side of our galaxy -- one that is teeming with planets. Because of Kepler, we now know that most stars have planets, Earth-sized planets are common, and planets...

WASHINGTON, Feb. 26, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized...

NASA WASHINGTON, Feb. 6, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler space telescope mission will be honored with the National Space Club's preeminent award, the Robert H. Goddard Memorial Trophy, in March. The National Space Club is recognizing Kepler for revolutionizing astrophysics and exoplanet science by expanding the census of planets beyond our solar system and fundamentally altering our understanding of our place in the Milky Way galaxy. The award citation acknowledges the...

Planet's Wild Ride Caught By Kepler Space telescope
2014-02-05 05:09:28

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Kepler space telescope has located a new planet that wobbles wildly on its axis much like a spinning toy top, with its tilt varying by as much as 30 degrees over an 11 year span, the US space agency announced Tuesday. The planet, which has been named Kepler-413b, follows an unusual 66-day orbit around a binary system comprised of an orange and red dwarf star. The planet, which is located 2,300 light-years away in the...

WASHINGTON, Feb. 4, 2014 /PRNewswire-USNewswire/ -- Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child's top. The tilt of the planet's spin axis can...

Rocky Exoplanets Too Hot To Support Life: Kepler Data
2014-01-07 05:07:34

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Kepler spacecraft team reported details about five new rocky planets on Monday at the American Astronomical Society meeting in Washington. Kepler has helped scientists discover hundreds of exoplanets, and astronomers at the event reported on four years of follow-up observations, as well as describing the new rocky planets discovered. According to the latest findings, Kepler-99b and Kepler-406b are 40 percent larger in size...

Scientists Meet To Discuss 833 New Exoplanets

Lee Rannals for redOrbit.com - Your Universe Online An international group of scientists are gathering for the second Kepler Science Conference this week at NASA’s Ames Research Center in Moffett Field, California. Researchers will be discussing the latest findings from the Kepler Space Telescope data, which includes the discovery of 833 new candidate planets. Ten of the new exoplanets are less than twice the size of Earth and orbit in the habitable zone. New Kepler data shows that...

Explanet Same Size As Earth
2013-10-30 16:15:10

Brett Smith for redOrbit.com - Your Universe Online In August, an international team of researchers announced the discovery of a planet outside our solar system - also referred to as an exoplanet - that orbits its star in just 8.5 hours and is roughly the same size as Earth. Now, the same research team members that found the planet, dubbed Kepler 78b, have made another startling discovery: the planet’s mass is roughly the same as our own. "This planet is a complete mystery," said...

Lyra Constellation -- Lyra (the lyre) is a prominent, although fairly small, northern constellation. It was one of Ptolemy's 48 constellations, and also counts among the modern 88 constellations. Its brightest star is Vega (Alpha Lyrae), which together with Altair (Alpha Aquilae) and Deneb (Alpha Cygni) forms the large asterism known as the Summer Triangle. Beta Lyr is a half separated (i.e. one of the stars reached its Rochevolume) eclipsing binary of a cream-white colour. The...

Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....

Ring Nebula -- Discovered by Antoine Darquier de Pellepoix in 1779. The famous ring nebula M57 is often regarded as the prototype of a planetary nebula, and a showpiece in the northern hemisphere summer sky. Recent research has confirmed that it is, most probably, actually a ring (torus) of bright light-emitting material surrounding its central star, and not a spherical (or ellipsoidal) shell, thus coinciding with an early assumption by John Herschel. Viewed from this equatorial...
