[ Watch the Video: Fight Between Tiny Star And Giant Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found evidence that a tiny star 37,000 light-years away from Earth is being bombarded by asteroids. Scientists say PSR J0738-4042, a star located in the constellation of Puppis, has been hit with an asteroid that had a mass of about a billion tons. The team used CSIRO's Parkes Observatory telescope and another telescope in South Africa to make the...

Exoplanet Hunter Selected By European Space Agency

[ 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,...

Exoplanet Search Techniques Needs To Be Refined

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...

WASP Gives NASA's Planetary Scientists New Observation Platform

April Flowers for redOrbit.com – Your Universe Online High-altitude balloons have long been used by scientists who study the Earth, the sun and the stars to gain a better view of their targets by carrying their telescopes far into the stratosphere. For planetary scientists, however, this doesn't work, as they need a highly stable, off-the-shelf type system that could accurately point their instruments and then track planetary targets as they move around in the solar system. Such a...

NASA WASHINGTON, Feb. 6, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler space telescope mission will be honored with the National Space Club's preeminent award, the Robert H. Goddard Memorial Trophy, in March. The National Space Club is recognizing Kepler for revolutionizing astrophysics and exoplanet science by expanding the census of planets beyond our solar system and fundamentally altering our understanding of our place in the Milky Way galaxy. The award citation acknowledges the...

Planet's Wild Ride Caught By Kepler Space telescope
2014-02-05 05:09:28

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Kepler space telescope has located a new planet that wobbles wildly on its axis much like a spinning toy top, with its tilt varying by as much as 30 degrees over an 11 year span, the US space agency announced Tuesday. The planet, which has been named Kepler-413b, follows an unusual 66-day orbit around a binary system comprised of an orange and red dwarf star. The planet, which is located 2,300 light-years away in the...

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...
