At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. In the first decades of the century, it became brighter and brighter, until, by April 1843, it was the second brightest star in the sky, outshone only by Sirius (which is almost a thousand times closer to Earth). In the years that followed, it gradually dimmed again and by the 20th century was totally invisible to the naked eye.

This simulation shows the future behaviour of a gas cloud that has been observed approaching the supermassive black hole at the centre of the Milky Way. This is the first time ever that the approach of such a doomed cloud to a supermassive black hole has been observed and it is expected to break up completely during 2013.

Geomagnetic storms due to coronal mass ejections (CMEs) earlier in the week have increased in strength, and are now rated a G3 on a scale from G1 to G5. This space weather is due to the March 7 activity from the sun that caused rapid changes to the shape of Earth's magnetosphere – the bubble of protective magnetic fields surrounding the planet -- resulting in a geomagnetic storm.

Martian Sand Dunes Caught in Motion | Wired Science | Wired.com
A rippled dune front in Herschel Crater moved about 1 meter between March 3, 2007 and Dec. 1, 2010. NASA’s Mars Reconnaissance Orbiter has caught sand dunes on the surface of Mars in the act of shifting.
The largest storm seen on Saturn in more than 21 years has now been encircling the planet for a record-breaking 200 days.

The European Space Agency’s Herschel space telescope has captured this gorgeous new view of the famed Eagle Nebula. The Eagle Nebula, located 6,500 light-years away in the constellation Serpens, is visible as a fuzzy red spot to backyard astronomers with a modest telescope.

Titan: A Wet World Not Far From Earth | Wired Science | Wired.com
Astronomers weekly announce the discovery of new exoplanets, some similar in size or temperature to our planet –- but Earth-like worlds are not always far away. Though Saturn's largest moon, Titan, is a small, cold world orbiting on the outskirts of the solar system, it actually boasts many familiar features. “Titan is fascinating because it has some surprising properties so similar to Earth,” said planetary scientist Oded Aharonson from the California Institute of Technology.There’s something about old photographs. The perfect combination of faded light, outdated coloring, and nostalgia seems to make them more beautiful with age.
