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 video, originally shot back in July at TAM 2011 Las Vegas , is of a panel featuring Bill Nye, astronomers Neil DeGrasse Tyson & Pamela Gay, and theoretical physicist Lawrence Krauss—and the entire discussion is moderated by Bad Astronomy ‘s Phil Plait. The subjects raised are consequential, the discussions thought provoking, and the opinions of the panelists refreshingly diverse (and often conflicting). OMGIROTFLAIJSMP also a Geekation mod.
Discovered: The first habitable 'Earth-like' planet An artist's conception of Kepler-22b, a planet 600 light years away from Earth, and the first confirmed planet outside our solar system that could conceivably harbor life as we know it. NASA/Ames/JPL-Caltech ay hello to " Earth 2.0. " NASA's planet-hunting Kepler spacecraft has discovered an alien world that might just support life as we know it. Here's what you need to know about Earth's new celestial cousin, Kepler-22b: What exactly is the Kepler mission?
The Earth wobbles. Like a spinning top touched in mid-spin, its rotational axis fluctuates in relation to space. This is partly caused by gravitation from the sun and the moon. logy Magazine
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. Rare Sight! See All 7 Planets in the Night Sky This Week | Solar System Planets & Skywatching Tips | How to Spot Planets in Night Sky

By Dean Praetorius | HuffingtonPost.com Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au . Betelgeuse, one of the night sky’s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time.
An alien world blacker than coal, the darkest planet known, has been discovered in the galaxy. The world in question is a giant the size of Jupiter known as TrES-2b. NASA's Kepler spacecraft detected it lurking around the yellow sun-like star GSC 03549-02811 some 750 lightyears away in the direction of the constellation Draco. The researchers found this gas giant reflects less than 1 percent of the sunlight falling on it, making it darker than any planet or moon seen up to now. [ The Strangest Alien Planets ]
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.

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.

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. All answers are provided by Dr.
An SUV Heads to Mars - The Top 10 Everything of 2011 Think the existing Mars rovers or the lunar dune buggies from the Apollo days were fun? Wait till Curiosity — an SUV-size rover that left Cape Canaveral in November — arrives on Mars on Aug. 6. The rover will be the biggest, most capable machine on the Red Planet by far, and it will get there in an improbable way — plunging through the Martian atmosphere, slowing itself down with parachutes and air resistance and then being lowered by cables from a hovering propulsion shell. A first act like that will be hard to follow, but the second act — at least two years of Martian exploration — will probably be more than up to the job. Next ET Arrives — or at Least His Raw Material
Japan announced last week that its Akari infrared space telescope was switched off after five years of scanning the sky in search of star-forming dust clouds, ancient galaxies in the distant universe, and asteroids within the solar system. The Akari mission succumbed to trouble in its power generation system, which first appeared in May and ended the satellite's scientific observations in June. The observatory stopped receiving electricity on the night side of its orbit around Earth, an indication its batteries were not charging sufficiently. The craft remained powered in sunlight.

The International Space Station's commander has again seen the grandeur of comet Lovejoy in new pictures taken from the orbiting outpost, this time also capturing the Earth's horizon and background stars in exquisite detail. These shots were snapped Thursday, two nights after NASA astronaut Dan Burbank serendipitously witnessed comet Lovejoy rising from behind the Earth as the station orbited 250 miles above the planet and the following night after producing this pictures .

News in Science Monday, 12 December 2011 ABC/Reuters Zeroing in There are loud rumours that scientists at the CERN physics research centre in Europe have seen the first strong signs of a particle vital to support Einstein's ideas on the working of the universe. While warning there would be no announcement of a full scientific discovery, scientists say even confirmation that something like the long-sought Higgs boson had been spotted would point the way to major advances in knowledge of the cosmos.
