2013-09-18 15:05:45

[ Watch the Video: Jupiter Moon's Cracks Due To Tilted Axis ] Lee Rannals for redOrbit.com - Your Universe Online New evidence shows that Jupiter's moon Europa most likely was once spinning around on a tilted axis. NASA scientists analyzed distinctive cracks lining the surface of Europa and found that the moon used to have a small tilt in its spin axis. This information could influence calculations of how much of the moon's history is recorded in its frozen shell, how much heat is...

Was Life On Earth Jump-Started By Icy Comet Impact?

Lee Rannals for redOrbit.com - Your Universe Online A new image taken by the high-resolution stereo camera on the European Space Agency's (ESA) Mars Express shows an area on the Red Planet that features radiating patterns. The mosaic is composed of four images of the Becquerel crater located in Arabia Terra, which is an area between the southern highlands and the northern lowlands of Mars. The Becquerel crater is the largest feature in the picture with a diameter of about 100 miles and...

Trojan Asteroids Are More Common Than Previously Believed

[ Watch the Video: QF99 Motion Animation ] April Flowers for redOrbit.com - Your Universe Online The first Trojan asteroid sharing the orbit of Uranus has been discovered by University of British Columbia astronomers who believe the asteroid - 2011 QF99 - is part of a larger-than-expected population of transient objects temporarily trapped by the gravitational pull of the solar system's giant planets. Trojan asteroids share the orbit of a planet and occupy stable positions known as...

Cassini Data Reveals Unexpected Features In Titan’s Icy Outer Shell
2013-08-28 15:52:50

[ Watch the Video: A Titan View from Huygens ] Lee Rannals for redOrbit.com - Your Universe Online Cassini, a joint NASA/ESA/ASI orbiter, arrived at Saturn a little over nine years and has been observing the ringed planet and its moons ever since. The latest data from the spacecraft shows that the planet's largest moon, Titan, has some unexpected features. A new study published in the journal Nature reveals that Titan's rigid outer ice shell has some features quite different from any...

Twin Star Insights Into Sun's Future

[ Watch the Video: The Life Cycle of a Sun-Like Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified what they are calling the Sun's oldest twin, HIP 102152, sitting 250 light-years away from us. A team of astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) found that HIP 102152 is older but otherwise nearly identical to our Sun, giving astronomers a chance to see how our local star will look as it ages. Our Sun is...

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...
