Australian astronomers find the oldest Star: 13.6 billion years old, making it the most ancient star seen. It lies in our own galaxy, the Milky Way, at a distance of around 6,000 light years from Earth. story dated: 10 Feb 2014

The Sword Of Orion - The Orion constellation is noticeable for three medium-bright stars in a short, straight row. These stars represent Orion’s Belt. If you look closely, you’ll notice a curved line of stars “hanging” from the three Belt stars. These stars represent Orion’s Sword. Look for the Orion Nebula about midway down in the Sword of Orion, otherwise known as M42, a stellar nursery where new stars are being born.

The bright, pinkish-white star at upper left of Orion is Betelgeuse. A red supergiant, it is one of the largest and most luminous stars known. If it were at the center of our solar system, its surface would extend to the orbit of Jupiter and beyond, wholly engulfing Mercury, Venus, Earth and Mars. Betelgeuse is approximately 640 light-years away from Earth.

Standing out: The bright, pinkish-white star at upper left of Orion, known as the hunter, is Betelgeuse. AKA a red supergiant, Betelgeuse is in the last stages of its life; increasing in size and sending its stellar material into space at a tremendous rat

Dark matter is an invisible material that emits or absorbs no light but betrays its presence by interacting gravitationally with visible matter. This image from Dark Universe shows the distribution of dark matter in the universe, as simulated with a novel, high-resolution algorithm at the Kavli Institute of Particle Astrophysics & Cosmology at Stanford University and SLAC National Accelerator Laboratory.

Scientists Have Discovered A Planet They Thought Was Impossible - Based on what we know about how solar systems form researchers thought that a giant rocky planet could not exist. but they just found one that's 17 times Earth's mass. They're calling it the Mega-Earth. Scientist say the new planet may have "profound implications for the possibility of life" on extra-solar planets, according to a the Harvard-Smithsonian Center for Astrophysics.

Astronomers find a new type of planet: The 'mega-Earth' The newly discovered 'mega-Earth' dominates the foreground of this artist's conception. has a diameter of about miles, times larger than Earth and weighs 17 times as much.

The Eridanus Void. This area shows almost no signs of cosmic matter, meaning no stars, planets, solar systems or clouds of cosmic dust. Researchers couldn't even find dark matter, which is invisible but measurable by its gravitational pull. There were also no signs of black holes that might have gobbled up the matter once present in the region.

The carina nebula - where stars born

ESO’s Very Large Telescope has delivered the most detailed infrared image of the Carina Nebula stellar nursery taken so far. Many previously hidden features, scattered across a spectacular celestial landscape of gas, dust and young stars, have emerged.
