Nasa: Moon's Crust Being Pulled Apart - In Places. Last updated 09:44 21/02/2012 New images acquired by NASA's Lunar Reconnaissance Orbiter spacecraft show that the moon's crust is being slightly stretched.
The moon's crust is being pulled apart in places, according to surprising new Nasa findings. Minute valleys have been discovered on the moon's surface. Scientists believed the geologic activity occurred less than 50 million years ago - recent compared to the moon's age of more than 4.5 billion years. Supernova Blast: Giant Star Eta Carinae to Explode Any Day. When the sun finally dies some 5 billion years from now, the end will come quietly, the conclusion of a long, uneventful life.
Our star will, in a sense, go flabby, swelling first, releasing its outer layers into space and finally shrinking into the stellar corpse known as a white dwarf. Things will play out quite differently for a supermassive star like Eta Carinae, which lies 7,500 light-years from Earth. Weighing at least a hundred times as much as our sun, it will go out more like an adolescent suicide bomber, blazing through its nuclear fuel in a mere couple of million years and exploding as a supernova, a blast so violent that its flash will briefly outshine the entire Milky Way. The corpse this kind of cosmic detonation leaves behind is a black hole. For Eta Carinae, that violent end might not be long in coming, according to a report in the latest Nature. But as the Nature report makes clear, that understanding may now be at hand. The future of space with Bill Nye, Neil deGrasse Tyson, Pamela Gay, and Lawrence Krauss discuss our future in space.

Rare Sight! See All 7 Planets in the Night Sky This Week. This week presents a rare opportunity to see all the major planets of the solar system in a single night. Just after sunset tonight (Dec. 21) the two brightest planets will be shining, weather permitting. Venus, the brightest, rides low in the southwest just above the setting sun. Jupiter, the second brightest planet, is high in the south. The Promise of Kepler-22b Video. SpaceX. Two Suns? Twin Stars Could Be Visible From Earth By 2012.

Dr. Dark alien planet discovered by NASA. Astronomer discovers 18 giant alien planets the size of Jupiter orbiting massive dying stars outside our own solar system. By Michael Zennie Updated: 00:08 GMT, 4 December 2011 A patient astronomer has discovered 18 massive new alien planets orbiting dying giant stars outside our solar system.
It is a finding that could help scientists better understand the origins of our own sun and the planets that orbit it. This is the second-largest batch of such planets ever found -- and increases the number of known alien bodies orbiting massive stars by 50 percent. California Institute of Technology Professor John Johnson and his team of astronomers spent nearly 10 years staring at 300 solar systems, searching for a tell-tale wobble caused by the gravitational pull from planets. Gas giants: All 18 planets found by Professor John Johnson and his team are roughly the size of Jupiter. Record-Breaking Photo Reveals a Planet-sized Object as Cool as the Earth.

These two infrared images were taken by the Spitzer Space Telescope in 2004 and 2009. They show a faint object moving through space together with a white dwarf. The brown dwarf, named WD 0806-661 B, is the coldest companion object to be directly imaged outside our solar system. Credit: Kevin Luhman, Penn State University, October 2011 19 October 2011 — The photo of a nearby star and its orbiting companion -- whose temperature is like a hot summer day in Arizona -- will be presented by Penn State Associate Professor of Astronomy and Astrophysics Kevin Luhman during the Signposts of Planets conference at NASA's Goddard Space Flight Center on 20 October 2011.
"This planet-like companion is the coldest object ever directly photographed outside our solar system," said Luhman, who led the discovery team. Click on either image below for a high-resolution version. Gravity Probe B - Special & General Relativity Questions and Answers. No.
Experiments continue to show that there is no 'space' that stands apart from space-time itself...no arena in which matter, energy and gravity operate which is not affected by matter, energy and gravity. General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field. This is not speculation, but sound observation. Return to the Special & General Relativity Questions and Answers page. An SUV Heads to Mars - The Top 10 Everything of 2011.

Radio telescopes capture best-ever snapshot of black hole jets. An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.
