It was tweeted in January by the commander of the International Space Station, Canadian astronaut Chris Hadfield. He's been making it his job to not only lead Expedition 35 of the ISS but also amass a dazzling collection of images of the Earth from space.
(Here's a full map of his images taken high above locations all over the world)

The group of scientists working with NASA's Curiosity rover made a big announcement during a press conference today: "We have found a habitable environment that is so benign" if there was water there, "you be able to drink it," John P. Grotzinger, professor of geology at Caltech, said summing up the rover's latest findings.
That is, at one point Mars had the right conditions to support living microbes.

Scientists have discovered a world much fancier than our homely, little Earth.
New research that will published in the journal Astrophysical Journal Letters details a planet that is eight times heavier than Earth and with twice its radius. But instead of being covered in water and granite, it is encrusted in graphite and diamond.
NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.
"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.
The Voyager 1 spacecraft's 35th anniversary is proving to be unexpectedly exciting, as scientists gathered this week to examine new hints that the spacecraft is on the verge of leaving our solar system.
Voyager 1 is now more than 11 billion miles away from Earth. It blasted off in September 1977, on a mission to Jupiter and Saturn. But it also carried a Golden Record filled with music and the sounds of our planet, in case it encountered intelligent life as it moved out toward the stars.

Before we run through the news of the day, let's pause for something spectactular: a new video from NASA's Solar Dynamics Observatory. It shows a "massive filament" eruption on the sun that occurred last Friday. As Britain's The Register says, it is "mind-bogglingly gorgeous."

Former astronaut Neil Armstrong, known for his words, "That's one small step for man, one giant leap for mankind," has died. The first man ever to walk on the moon was 82.
Update at 5:15 p.m. ET:
Armstrong's family has released a statement, saying he died following cardiovascular procedures. NASA published it here. They say, "Armstrong was also a reluctant American hero who always believed he was just doing his job."
In 1983, Sally Ride became the first American woman in space. She blasted off aboard Challenger, culminating a long journey that started in 1977 when the Ph.D. candidate answered an ad seeking astronauts for NASA missions.
