Future lunar explorers counting on the moon to shield themselves from galactic cosmic rays might want to think about Plan B.
In a surprising discovery, scientists have found that the moon itself is a source of potentially deadly radiation.
Measurements taken by NASA’s Lunar Reconnaissance Orbiter show that the number of high energy particles streaming in from space did not tail off closer to the moon’s surface, as would be expected with the body of the moon blocking half the sky.

It is April 12th 1961 and Yuri Gagarin is about to see what no other person has seen in the history of humanity – the Earth from space. In the next 108 minutes he’ll see more than most people do in a lifetime. What sights awaited the first cosmonaut silently gliding over the world below? [...]

A NASA center and the Pentagon’s lead research group are striking financial flint to steel in hopes of sparking a sustained effort to make interstellar space travel a reality.
On Thursday, an official with the Defense Advanced Research Projects Agency (DARPA) announced that the agency will award a $500,000 grant to the person or group who [...]

50 years ago, on April 12th, a human went into space for the first time. Let’s say that again, for emphasis: a human went into space. In a rocket. To space. His name was Yuri Gagarin and he is an undeniable legend.
Sure, his fame might be overshadowed somewhat by those showoff Americans Buzz Adrin and [...]

NASA has been implementing an Open Government Plan for nearly a year, and this week they held the first NASA Open Source Summit in Mountain View, CA. But the roots of open source at NASA go back much further, to its founding legislation in 1958, which designed NASA as a source that would “provide for [...]

In May of 2010, Astronomers using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton detected a vast reservoir of gas lying along a wall-shaped structure of galaxies about 400 million light years from Earth. In the image above the spiral and elliptical galaxies are shown in the Sculptor Wall along with the newly detected intergalactic gas, [...]

Everyone knows that “the moon on the breast of new-fallen snow gives the luster of mid-day to objects below.” That is, except during a lunar eclipse.
The luster will be a bit “off” on Dec. 21st, the first day of northern winter, when the full Moon passes almost dead-center through Earth’s shadow. For 72 minutes of [...]

NASA has discovered a new life form, a bacteria called GFAJ-1 that is unlike anything currently living in planet Earth. It’s capable of using arsenic to build its DNA, RNA, proteins, and cell membranes. This changes everything. Updated.
NASA is saying that this is [...]

The total number of stars in the Universe “is likely three times bigger than realized.” Yale University astronomer Pieter van Dokkum says there are “possibly trillions of Earths orbiting these stars,” dramatically increasing the possibility of finding alien civilizations.
According to the new study just published in Nature, new observations on the red end of the [...]

The two objects were only identified at the weekend by the Nasa-funded Catalina Sky Survey near Tucson, Arizona, during a routine sky scan.
The first asteroid, christened 2010 RX30, was about 65 feet (20 metres) in diameter and flew past at a distance of 154,000 miles early at 9:51am on Wednesday.
The second, called 2010 RF12, [...]
Using data from a NASA radar that flew aboard India’s Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon’s north pole. NASA’s Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to15 km) in diameter. Although [...]
