To put up first Brazilian geostationary satellite

Brazilian aircraft manufacturer Embraer and state telecommunications Telebras signed the shareholders agreement that gives life to the company that developed and built the first geostationary satellite for military and civilian communications the country. The new company, dubbed Space Visiona SA, will be controlled by Embraer (51 percent), which is the third largest worldwide manufacturer of aircraft and military and space technologies developed, and will have as a minority partner (49 percent) Telebras, a state telephone company whose main assets were privatized over a decade.

A new calculate of potentially dangerous asteroids

Comments approved out by the Wide Field Infrared Explorer to Survey (Wide-field Infrared Survey Explorer, or WISE, for its acronym), NASA, have yielded the best on record count Today the population of potentially hazardous asteroids in our solar system. Also known as "PHAs" (acronym for Potentially Hazardous English Asteroids), these asteroids have orbits within about eight million kilometers (five million miles) from Earth's orbit and are large enough to survive passing through the Earth's atmosphere and cause damage on a regional,

A cosmic collision might fade away the water

A cosmic impact might have been the cause of a temporary warming of Mars and, therefore, the disappearance of water on its surface, according to a study published in international 'Astrobiology Magazine. Experts have said that this discovery could help explain how a planet so cold and dry ever could contain liquid water and potentially favorable conditions for life.

From the center of the galaxy Ghost beams of gamma rays rising

The center of the Milky Way shows little activity in contrast. It was not always so peaceful. New evidence of ghost beams of gamma rays suggests that the central black hole of our galaxy was much more active in the past.

"These jets are faint ghost or just a sequel to what existed for millions of years," said Meng Su, an astronomer at the Harvard-Smithsonian Center for Astrophysics (CfA), and author of a new article in the Astrophysical Journal. "But it reinforces the evidence that there was an active galactic nucleus in the relatively recent past of the Milky Way," he added.

Seagrasses , healthier 'enterradoras' forest carbon

The green meadow of Posidonia underwater that exist close to coastlines, and are seriously damaged by polluting discharges, trawling and pleasure craft facilities, are capable of capturing and storing carbon twice the lush tropical forests. A study of seagrass, thousand around the world has shown that under the sea there are 'sinks' that help fight climate change.

The work has been developed by a team of scientists from several countries, including experts from the Spanish National Research Council (CSIC) and has been published in the journal Nature Geoscience. "

A garden center of stars the "nebula of war and peace”

The Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Chile has allowed a group of astronomers to find an extraordinary image of the nebula NGC 6357, a nursery of stars known as the "nebula of war and peace”

The scientific body said, this new panoramic, obtained from the ESO Observatory at Cerro Paranal has, in the Atacama Desert, shows numerous hot young stars, glowing clouds of gas and dust strange formations sculpted by ultraviolet radiation and stellar winds.

The outline of "Mickey Mouse" on Mercury

This is not any joke or false move. The U.S. space agency shared his Flickr account this unique picture with the title "Mickey Mouse found on Mercury". The photograph is from the surface of the planet from the sun and the silhouette resembles the popular character created by Disney Studios. NASA explained that the photograph was taken by the MESSENGER spacecraft and is the result of a whimsical combination of craters and shadows in the global south. "The shadow helps define the striking resemblance to" Mickey Mouse ", created by the longest accumulation of craters on the geologic history of Mercury," NASA said in describing the picture. Messenger is the first spacecraft to orbit Mercury and during their first year of mission took 88,746 images and other data sets.
