NASA Attempts 'Hail Mary' To Recover Kepler Space Telescope
2013-07-19 14:23:40

Lee Rannals for redOrbit.com - Your Universe Online NASA is launching a last-ditch "Hail Mary" attempt to try and bring its Kepler mission back to life. The US space agency said that over the next week, the Kepler team will attempt tests to explore recovery of the spacecraft's reaction wheels, which failed back in May. Kepler needs its reaction wheels to help stabilize it as it searches for exoplanets around distant stars. The team will be continuing its efforts to conduct tests on...

Planets May Keep Warmer In A Cool Star System
2013-07-19 13:49:17

Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Astrobiology, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. Stars emit different types of light, with hotter stars emitting high-energy visible and ultraviolet light, and cooler stars giving off infrared and near-infrared light. A new climate model found that planets orbiting cool stars actually may be warmer and less icy than...

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...

Stellar Magnetic Fields Affect Possibility For Life Beyond Earth
2013-07-05 04:31:00

John P. Millis, PhD for redOrbit.com - Your Universe Online The presence of an atmosphere - among many other factors - is vital for the evolution of life as we know it on a planet. However, this seemingly simple requirement is bathed in a multitude of variables that can affect its creation and existence. Thus, establishing an atmosphere is by no means a trivial detail. Scientists believe mechanisms such as volcanic eruptions, other tectonic activity and even comet impacts could all play...

New Super Earth Found 70 Light Years Away
2013-07-02 14:19:36

Brett Smith for redOrbit.com - Your Universe Online Using the Canadian Microvariability & Oscillations of Stars (MOST) telescope, an international team of researchers has uncovered new details about a relatively close Earth-sized planet, according to a new report in the Astrophysical Journal Letters. The star, known as HD 97658, sits just 70 light-years away from Earth and can almost be seen with the naked eye. In 2011, astronomers first discovered a planet orbiting the nearby star,...

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...

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...

NEW YORK, June 18, 2013 /PRNewswire/ -- Lone Signal launches the first continuous mass METI (Messaging to Extraterrestrial Intelligence) initiative via the newly recommissioned Jamesburg Earth Station in Carmel, California. Lone Signal will provide anyone with an Internet connection the opportunity to compose and transmit messages to stars suspected to harbor habitable planets orbiting within their circumstellar habitable zones - otherwise referred to as "goldilocks zones." Lone Signal's...

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...
