The cool Y dwarfs are also close to the Sun. They are 40 light years away, making them one of the closets to our solar system. The closest, Proxima Centauri, is about four light years away.
Just as a Russian company announced its big idea to build an orbiting hotel 217 miles above earth, A Russian Progress M-12M cargo ship has failed to reach orbit, according to the Interfax news agency.
NASA's Wide-field Infrared Survey Explorer has discovered six dwarf stars, which are colder than any of the others it has discovered.
Scientists have discovered the coldest class of star-like bodies with temperatures as cool as the human body. It is nearly impossible to see these stars with a visible-light telescope.
NASA's human-like 300-pound robot, Robonaut 2 or R2, which reached the International Space Station six months ago to act as an astronaut's assistant, has been powered up for the first time.
With maximum sustained winds of 110 miles (175 kilometers) per hour, hurricane Irene is heading toward the Carolina states in the U.S. and is just 955 miles (1,535 kilometers) of North Carolina.
Though Hurricane Irene has weakened to a Category 1 hurricane, it is expected to hit along the North Carolina coast, heading north into Virginia and up the Chesapeake Bay by Sunday morning.
The astronauts at the International Space Station have got a new company, a humanoid robot, which was activated on Monday, six months after it got delivered to the space station.
the Russian company Orbital Technologies is building a space hotel that will accommodate up to seven celestial travelers.
NASA has teamed up with Tor/Forge Books in a project to publish and develop Sci-Fi novels, the NASA Space Flight center has announced.
NASA has re-estimated the cost for flying the James Webb Space Telescope that is set to operate at the Earth-Sun L2 Lagrange point by 2018 as $8.7 billion.
Hurricane Irene is heading towards the U.S. East Coast and is forecast to make a possible landfall in mainland U.S. in Florida, Georgia or California by the end of the week.
At a time when Obama administration has asked federal agencies to plan for budgets that are at least 10 percent below their current appropriation level, NASA has raised the total estimated cost of the James Webb Space Telescope (JWST) to $8.7 billion.

With NASA's space shuttle program at an end, artists Neil DaCosta and Sarah Phillips have visualized the loss of the American icon in Astronaut Suicides.
It may take a while to get there, but it seems that the prospect of a space hotel is not that far off as a Russian company announces plans to build an orbiting hotel 217 miles above Earth.
When a team of geologist unearthed 3.4-billion-year-old fossils, the microfossils preserved in the form of tiny circles and tubes meant much more than mere discovery of the oldest fossils on earth.
NASA's satellite captures Irene from space and shows how it grew from a tropical storm to a hurricane.
The oldest known fossils on earth have been discovered by a team of British and Australian geologists in the Australian Outback, giving clues about the origin of life on earth and hinting that similar lifeforms could exist on other planets like mars.
Researchers have discovered fossils of microbial organisms that were living on Earth 3.4 billion years ago. Earth's oldest fossils have been found in Australia by a team from the University of Western Australia and Oxford University. The microscopic fossils show convincing evidence for cells and bacteria living in an oxygen-free world over 3.4 billion years ago.
NASA's Mars Exploration Rover (MES) Opportunity, which recently reached the Red Planet's Endeavor crater, sent back interesting snapshots of the planet's crust.
Predictions of extraterrestrials invading Earth to destroy our civilization and save the rest of the universe, attributed to NASA, have been disavowed by their author.
