Exoplanet Search Techniques Needs To Be Refined
2014-02-20 04:11:01

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year. The holy grail, of course, would be the detection of an Earth-like world. Specifically, astronomers are looking for a planet of similar size to our...

Hot Jupiters More Nuanced Than Expected

April Flowers for redOrbit.com - Your Universe Online In addition to the eight beloved planets circling our Sun, our galaxy is literally teeming with an enormous variety of planets. More than 800 of the so-called exoplanets have been identified circling stars beyond our solar system. And several different “species” of exoplanets have been discovered as well, including so-called ℠roasters´ or ℠hot Jupiters,´ which are gas giants like our own Jupiter that...

Exoplanet's Atmosphere Unveiled Through New Observing Technique
2012-06-27 13:04:31

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com Astronomers have uncovered a clever new way of studying the atmosphere of an exoplanet in more detail. An international team of astronomers used the European Space Observatory's Very Large Telescope to see the faint glow from the planet Tau Boötis b. For the first time, the team reported that it has been able to study the planet's atmosphere, and was able to measure its orbit and mass precisely. They wrote in...

Astronomers claim to have discovered an exoplanet that is the most similar to Earth in terms of mass than any previously discovered. Found in the constellation Libra, the planet known as Gliese 581 represents about twice the mass of Earth. Astronomers have previously identified some 300 exoplanets, but most are much larger than Earth. "This is by far the smallest planet that's ever been detected," said Michael Mayor, from the Geneva Observatory, Switzerland. "This is just one more step in the...

A harvest of low-mass exoplanets discovered with HARPS Today, at an international conference, a team of European astronomers announced a remarkable breakthrough in the field of extra-solar planets. Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307. Moreover, looking at their entire sample studied with HARPS, the astronomers count a total of 45 candidate planets with a mass below 30 Earth masses and an orbital...

AMES, Iowa -- An international team of astronomers that includes Steve Kawaler of Iowa State University has announced the first discovery of a planet orbiting a star near the end of its life. The announcement, culminating seven years of research, will be published in the Sept. 13 issue of the journal Nature. The news provides a preliminary picture of what could be the Earth's destiny in four to five billion years. That's when the sun will exhaust its hydrogen fuel, expand enormously as a red...

Earth's inhabitants are used to temperatures that vary, sometimes greatly, between day and night. New measurements for three planets outside our solar system indicate their temperatures remain fairly constant "“ and blazing hot "“ from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent darkness. The reason apparently is supersonic winds, perhaps as strong as 9,000 miles an hour, that constantly churn the planets'...

The launch of COROT on December 21, 2006 is a long awaited event in the quest to find planets beyond our Solar System. Searching from above the Earth's atmosphere, COROT "“ the CNES project with ESA participation - will be the first space mission specifically dedicated to the search for extrasolar planets. COROT is expected to greatly enlarge the number of known exoplanets during its two-year mission and provide the first detection of rocky planets, perhaps just a few times the mass of...

Medusa had been one of three beautiful sisters. Athena was angered that Medusa met with Poseidon in one of her temples. She changed Medusa into a terrible monster. Zeus kept Pegasus out of the world to placate Athena. Pegasus (and the warrior Chrysaor) sprang from...
