Hunting For Exoplanets
2013-07-19 10:34:45

redOrbit Staff & Wire Reports - Your Universe Online The hunt is on for planets that, like Earth, have the conditions necessary for life to survive on their surfaces. But what exactly are scientists looking for? Earlier this week, NASA officials shed a little light on precisely what conditions they are seeking on worlds located beyond our solar system. These worlds, which are also known as exoplanets, have to meet a handful of different criteria in order to be considered potentially...

Clouds May Help Reveal More Habitable Planets
2013-07-02 05:48:46

April Flowers for redOrbit.com - Your Universe Online According to a new study from the University of Chicago and Northwestern University, the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting the most common type of stars in the universe, red dwarfs. In the Milky Way alone, the findings suggest, 60 billion planets may be orbiting red dwarf stars in the habitable zone. The study, published in Astrophysical Journal Letters, is based on...

Red Dwarf Stars May Destroy Possibility Of Life In Their Systems
2013-07-01 18:43:05

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Most of the stars in the Universe are classified as red dwarf stars - stars considerably smaller and cooler than our Sun. About 75 percent of the main sequence stars in our galaxy are classified as such, so they represent an exciting population to study in the search for life beyond Earth. If it were found that Earth-like planets formed around red dwarf stars, then the door would be opened to the possibility we might soon...

Sterilized Mars spacecraft largely a waste of money Two university researchers say environmental restrictions have become unnecessarily restrictive and expensive–on Mars. Writing in the journal Nature Geoscience, astrobiologists Alberto Fairén of Cornell University and Dirk Schulze-Makuch of Washington State University say the NASA Office of Planetary Protection's "detailed and expensive" efforts to keep Earth microorganisms off Mars are making missions to search for...

Three Habitable Super-Earths Discovered In Multi-Planetary Star System
2013-06-25 10:50:04

WATCH VIDEOS: [Gliese 667C Planetary Orbits] | [Animation of Gliese 667C System] Lee Rannals for redOrbit.com – Your Universe Online Astronomers have discovered a record-breaking planetary system with at least six planets orbiting its host star. New observations of Gliese 667C show for the first time that three of these six new planet candidates are super-Earths. In order for a planet to qualify as a super-Earth, it must exist within the "habitable zone," which is the zone around...

White Dwarf Star Cooling Rates Updated By New Data
2013-05-29 16:00:35

Lee Rannals for redOrbit.com — Your Universe Online University of British Columbia (UBC) astronomers have determined that white dwarfs cool more slowly in the early stages of their life than models have previously predicted. White dwarfs are the dense, hot remnant cores of stars that have used up all of their fuel and lost their outer layers during the red giant phase. When these objects form, their surface temperatures are very hot, but cool over time as they radiate their...

Earth-Like Planets Discovered In Atmospheres Of Dead Stars
2013-05-09 14:38:45

[ Watch the Video: Ring of Rocky Debris Around a White Dwarf Star ] Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has helped astronomers spot signs of Earth-like planets in an unlikely place. Astronomers say they found the planets sitting in the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them, and the researchers say this discovery...

NASA's Charles Bolden Speaks At Humans To Mars Summit
2013-05-07 04:47:08

[ Listen to the Podcast Series: Is A Mission To Mars Possible? ] Lee Rannals for redOrbit.com - Your Universe Online During the Humans to Mars Summit at George Washington University yesterday, NASA Administrator Charles Bolden laid down some thoughts about the US space agency sending man to the Red Planet. Bolden started off his keynote speech by addressing the growing international interest in sending humans to Mars, while also pointing out how even President Barack Obama has...

What Really Makes A Habitable Planet?
2013-05-04 05:41:48

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The Holy Grail in the search for planets outside our solar system is finding one that could potentially support life. Traditionally, this means finding a planet with features similar to Earth, which is just the right distance from its host star that liquid water could be supported on the surface. Scientists believe the presence of liquid water on the surface is a necessary component for the proliferation of life. And a...

NASA, NatGeo To Celebrate Earth Day With Special Events
2013-04-20 08:00:02

Lee Rannals for redOrbit.com — Your Universe Online We all feel the pain of what has taken place in Boston and Texas this week, and for some we need to find a little bit of joy to help get out of the funk these disasters have caused. Fortunately, Earth Day is right around the corner, and it can allow us to help find a little peace from such an unpleasant week. Events such as the Boston Marathon bombings can unify the people impacted, as well as any resident of this planet who has...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
