April Flowers for redOrbit.com - Your Universe Online Three new Kuiper Belt objects (KPOs) that could possibly be visited by the New Horizons spacecraft have been uncovered by the Hubble Space Telescope. The KBO visit could happen after the spacecraft flies by Pluto in July 2015 as part of its primary mission. The New Horizons search team was awarded dedicated telescope time with Hubble to specifically search for such KPOs, which led to the current discovery. “This has been a very...

WASHINGTON, Oct. 9, 2014 /PRNewswire-USNewswire/ -- A team of scientists using NASA's Hubble Space Telescope has made the most detailed global map yet of the glow from a turbulent planet outside our solar system, revealing its secrets of air temperatures and water vapor. http://photos.prnewswire.com/prnVAR/20081007/38461LOGO Hubble observations show the exoplanet, called WASP-43b, is no place to call home. It is a world of extremes, where seething winds howl at the speed of sound from a...

Brett Smith for redOrbit.com - Your Universe Online A new analysis of images captured by the European Space Agency’s Rosetta spacecraft has revealed new details about the history of asteroid Lutetia and found evidence of a hidden impact crater on a part of the asteroid’s southern hemisphere which is hidden from view. Rosetta flew past the 62-mile wide Lutetia in July 2010 on the way to its destination, comet 67P/Churyumov-Gerasimenko. The ESA spacecraft was able to capture images of...

water in our Solar System

Chuck Bednar for redOrbit.com - Your Universe Online The water found on planet Earth predates the formation of the sun – a discovery that could have implications in the ongoing search for life on other planets, according to research appearing in Friday’s the journal Science. Scientists have long wondered whether the water found on our planet, in lunar craters and elsewhere originally came from ice ionized when the solar system was formed, or if it actually predated the solar system...

Lee J. Siegel, University of Utah What’s rocky, about a mile wide, orbits between Mars and Jupiter and poses no threat to Earth? An asteroid named “Univofutah” after the University of Utah. Discovered on Sept. 8, 2008, by longtime Utah astronomy educator Patrick Wiggins, the asteroid also known as 391795 (2008 RV77) this month was renamed Univofutah by the International Astronomical Union’s Minor Planet Center in Cambridge, Massachusetts. “It’s neat,” Wiggins says....

Chuck Bednar for redOrbit.com - Your Universe Online Pluto may no longer be a planet in the eyes of the International Astronomical Union (IAU), but as a recent debate hosted by the Harvard-Smithsonian Center for Astrophysics (CfA) revealed, not everyone agrees with the official assessment that led to its 2006 demotion. “What is a planet? For generations of kids the answer was easy. A big ball of rock or gas that orbited our Sun, and there were nine of them in our solar system,” the...

exoplanet sun wobble

April Flowers for redOrbit.com - Your Universe Online It would seem like a star couldn't be affected by anything less than another star, but new evidence from Cornell University reveals that "hot Jupiters," or large gaseous exoplanets, can cause their host stars to wobble as the planets wind their way through their own solar systems to snuggle up against their suns. "Although the planet's mass is only one-thousandth of the mass of the sun, the stars in these other solar systems are...

Jacqueline Faherty, Carnegie Institution A team of scientists led by Carnegie's Jacqueline Faherty has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets--Jupiter, Saturn, Uranus, and Neptune--but have not been seen outside of the planets orbiting our Sun until now. Their findings are published Tuesday, Sept. 9 by The Astrophysical Journal Letters and are available here. At the Las Campanas...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...
