Using A Stellar Ultrasound To Determine Ages Of Young Stars
2014-07-04 11:40:33

Brett Smith for redOrbit.com - Your Universe Online Before they become full-fledged stars, young embryonic stars are essentially contracting molecular clouds of gas and dust particles. The age of these ‘baby stars’ is difficult to gauge, but a newly published study in the journal Science has revealed scientists used a technique similar to ultrasound technology to determine the age of these young stars. "Think of it as ultrasound of stellar embryos," explained study author Jaymie...

Exoplanet Hunter Selected By European Space Agency
2014-02-20 04:31:01

[ Watch the Video: The Newest Exoplanet Hunter - PLATO ] April Flowers for redOrbit.com - Your Universe Online One of the hottest topics in 21st century science is the exploration of planets around stars other than our own Sun. These planets are known as extrasolar planets, or "exoplanets." One of the key goals of such research is to discover and learn about the properties of Earth-like worlds in the Sun's neighborhood. The European Space Agency (ESA) is preparing a new space mission,...

Pulsating Star Observations Shed New Light On Planetary Systems
2013-07-30 09:10:51

April Flowers for redOrbit.com - Your Universe Online An international team of scientists, including physicists at New York University, Princeton University and the Max Planck Institute for Solar System Research, has devised a method for measuring the internal properties of a star that offers more accurate assessments of the star's orbiting planets. The team examined a star approximately 92 light-years away and almost 20 percent more massive than our Sun, called HD 52265. Scientists...

Solar Twin Revealed By CoRoT
2013-05-20 06:06:03

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Our knowledge of how stars evolve arises out of our survey of billions of stars within and outside of our galaxy. As we piece together the snapshots of these stars of various sizes and masses, at various stages of their evolution, we begin to get a complete picture of how stars are born, live, and die. Of course, stars most similar to our Sun are perhaps the most relevant as they can tell us about our Sun´s past...

Astronomers Study Venus Atmosphere During Transit

[WATCH VIDEO: Ultra-High Definition View of 2012 Venus Transit] Lee Rannals for redOrbit.com — Your Universe Online It won't happen again until 2117, but one team ensured everyone at the 44th meeting of the American Astronomical Society's Division for Planetary Sciences in Reno, Nevada that they got plenty of data as Venus transited the Sun earlier this year. Jay Pasachoff of the Williams College and Caltech, Glenn Schneider of University of Arizona, Thomas Widemann of Paris...

Distant Planet Blasted With X-rays From Nearby Star
2011-09-14 05:56:33

  A nearby star is pummeling a companion planet with a barrage of X-rays 100,000 times more intense than the Earth receives from the sun. New data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope suggest that high-energy radiation is evaporating about 5 million tons of matter from the planet every second. This result gives insight into the difficult survival path for some planets. The planet, known as CoRoT-2b, has a mass about...

The French-led CoRoT (Convection, Rotation and planetary Transits) satellite has found ten new planets outside our Solar System. The new find brings the total number of known exoplanets to 561.  CoRoT launched in 2006 and it spots planets by measuring the tiny dip in stellar light that occurs when planets pass between the stars and the Earth. The spacecraft has added 23 planetary systems to the roster so far. CoRoT went into orbit shortly after NASA's Kepler, which is a similar...

Star known as HD49933 is located 100 light years away from Earth In a bid to unlock long-standing mysteries of the sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star. By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the sun's solar cycle. Results of the study, conducted by scientists at the U.S. National Center for Atmospheric Research (NCAR) in Boulder, Colo., and...

By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the Sun's solar cycle.The study, conducted by scientists at the National Center for Atmospheric Research (NCAR) and colleagues in France and Spain, is being published this week as a "Brevia" in Science.The scientists studied...

By detecting the faint dimming in the light emitted by stars during a transit event, CoRoT has detected six new exoplanets - each with its own peculiar characteristics - and one brown dwarf. One of these exoplanets, designated CoRoT-11b, has twice the mass of Jupiter and orbits a rapidly rotating star; this type of star is an extremely difficult target for exoplanet searches and its detection marks a significant achievement for the CoRoT team. In order to detect planets orbiting other suns,...
