Space Radiation Threat to Astronauts Explained (Infographic)
How Radiation in Space Poses a Threat to Human Exploration (Infographic) by Karl Tate, SPACE.com Infographics Artist
Earth's 6-Year Twitch Changes Day Length
Supercomputer model of Earth's magnetic field. Scientists believe that gyrating iron fluid generates Earth's magnetic field, like a giant dynamo. Both yearly and millennial-scale changes in the field have been attributed to the swirling, spinning outer core. Tracking changes in the magnetic field helps researchers create models of how the dynamo may work.
The Guardian On 'The Grand Design'
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
NASA astronauts capture rare 'red sprites' above Earth
Astronauts on board the International Space Station recently captured two photos of rare, mysterious "red sprites" — atmospheric phenomenon associated with powerful thunderstorms on Earth
Chasing Wormholes: The Hunt for Tunnels in Space-Time
Chasing Wormholes: The Hunt for Tunnels in Space-Time. Folding of Space-Time, Science fiction literature is full of stories in which tunnels in space-time — known as wormholes — are used for time travel. How much fact lies within the fiction? The answer is, more than you might think. Scientists are looking at ways to use traversable wormholes (if they exist) to travel faster than the speed of light — and even to travel through time itself.

NGC 6888 - Crescent Nebula, is a cosmic bubble about 25 ly across, blown by winds from its central, bright, massive star. NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). NGC 6888 is about 5000 ly away in the constellation Cygnus.

This all-sky view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. The image is derived from the 2MASS Extended Source Catalog, which contains more than 1.5 million galaxies, and the Point Source Catalog, which holds nearly 500 million stars in the Milky Way.
This is What 43,000 Galaxies Look Like On a Map
43,000 Galaxies on a Map / the most complete map of our local universe to date. It took more that ten years to create, has 43,000 galaxies and extends out 380 million light years from the earth. The 3D coordinates of each galaxy was recorded so the raw data could potentially be used to build a realistic 3D model of the universe.

In August of 2007, astronomers located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen. The large void in the Constellation Eridanus appears to be improbable given current cosmological models. A radical and controversial theory proposes that it is a "universe-in-mass black hole"

This is the highest resolution image of Earth ever made, 121 megapixels. That’s an amazing 0.62 miles per pixel. It was taken by Russia’s latest weather satellite, the Electro-L, which is orbiting Earth on a geostationary orbit 36,000 kilometers above the equator, sending photographs of the entire planet every 30 minutes.
