The United Nations has declared 2015 the International Year of Light in order to “highlight to the citizens of the world the importance of light and optical technologies in their lives, for their futures, and for the development of society.”
NASA seems more than eager to help with the effort. It’s just released a set of spectacular photos (see below) taken by its Chandra X-Ray Observatory space telescope.
“From a distant galaxy to the relatively nearby debris field of an exploded star, these images demonstrate the myriad ways that information about the universe is communicated to us through light,” the agency said.

A group of ornithologists led by Dr Manuel Schweizer from the Natural History Museum of Bern in Switzerland has described a new cryptic species of owl that inhabits the desert areas of Israel, Egypt, Saudi Arabia, Jordan, Oman and Yemen. The newly-discovered species, named the Desert Tawny Owl, belongs to the earless owl genus, Strix. [...] —> Read More Here

In many ways Breno Washington is a typical 15-year-old boy. He has the look of someone whose body grew slightly too quick for him, but he wears it easy anyway, like a pair of good jeans; he likes the Chicago Bulls and sometimes he smokes marijuana with his friends. Unlike most boys his age, however, Breno can never go home. If he does, he says, he will be killed by military police.
We are talking in an empty classroom in Rio de Janeiro’s Lapa neighborhood at the head office of Brazilian NGO São Martinho, which runs various programmes to help street children in the city. Outside, a football match is underway, and whistles and sneaker-squeaks pierce through the walls.
After leaving school in the fifth grade, Breno began sniffing paint thinner. Together with a group of friends, he committed a spate of robberies, until one day about a year ago Breno stole a motorcycle from a neighborhood police officer. “He tried to kill me, so I ran away from the community and started living —> Read More Here

On January 5 NASA captured a1.5 billion pixel image (69,536 x 22,230) that requires more than 4 GB of disk space. Its is an image of the Andromeda Galaxy and it was captured using the NASA/ESA Hubble Space Telescope. One image contains 100 million stars and takes you to more than 40,000 light years.
