How Many Habitable Exoplanets Exist
2013-11-26 13:17:30

John P. Millis, PhD for redOrbit.com - Your Universe Online In the last decade, exoplanet scientists have been finding new worlds at a brisk pace. But as the number of planetary bodies in our galaxy rises, questions about how many of these may, in fact, be habitable have been reaching a crescendo. The debate centers on the criteria for what it takes for a planet to be considered habitable. It seems the presence of liquid water on the surface is necessary, though some researchers are now...

Sunny Outlook For NASA Kepler's Second Light
2013-11-26 12:09:10

NASA You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again. A new mission concept, dubbed K2, would continue Kepler's search for other worlds, and introduce new opportunities to observe star clusters, young and old stars, active galaxies and supernovae. In May, the Kepler spacecraft lost the second of four gyroscope-like reaction wheels, which are used to precisely point the...

In The Hunt For Habitable Planets, A New Model May Be Key
2013-11-14 13:54:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers using new theoretical models have created a new method to simplify the search for Earth-like planets. The new models help rule out the possibility of Earth-like conditions on certain planets outside of our solar system. Yann Alibert, of the Center for Space and Habitability (CSH) at the University of Bern, and colleagues based the study on the mass and radius of a planet, helping to determine criteria that exclude the...

Alien Worlds: How Common Are Habitable Planets?

[ Watch the Video: Earth May Not Be So Unique After All ] redOrbit Staff & Wire Reports - Your Universe Online New statistical analysis of data obtained by NASA’s now-retired Kepler spacecraft has revealed that one out of every five sun-like stars have at least one Earth-sized planet in the habitable zone. “What this means is, when you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only...

Scientists Meet To Discuss 833 New Exoplanets
2013-11-04 16:21:02

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...

NASA will video stream a news briefing at 10:15 a.m. PST (1:15 p.m. EST) Monday, Nov. 4, to announce new results from the agency's Kepler mission. The briefing, taking place during the Kepler Science Conference, will be in building 152 at NASA Research Park in Moffett Field, Calif. With its 2009 launch, Kepler became the first NASA mission capable of finding Earth-sized planets in or near the habitable zone -- the region around a star in which orbiting planets may have surface temperatures...

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...

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...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

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...

penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
