One of the great discoveries of the coming century will be the direct detection of dark matter. This mysterious substance, thought to compose some 23% of the mass of our universe, is currently one of the most-sought substances in existence, the source of thousands of scientific papers and endless hours of speculation over the last half of the last century, despite the fact that it has not yet been directly detected. Now an analysis of 41 billion cosmic rays striking a state-of-the-art instrument called the Alpha Magnetic Spectrometer (AMS) particle detector aboard the International Space Station (ISS) may have come close to detecting dark matter.
Lethal aggression is something that chimpanzees naturally do, the study says, regardless of whether human impacts are high or low
Here’s a Friday FAQ in honor of the passing of the summer.
NASA’s Dawn spacecraft – now in route to the dwarf planet Ceres, the largest object in the asteroid belt – unexpectedly went into safe mode on September 11, 2014, but it has now recovered. It is now due to reach Ceres in April 2015. That’s a month later than originally scheduled, thanks to this month’s setback.
Here’s a collection of 10 unexpected, intriguing facts about the stars of our universe – including our sun – that you probably didn’t know!
September 18, 1977. Previous images had shown a part of the Earth, and a part of the moon, together. But – until this image by Voyager 1, taken on today’s date 37 years ago – we had never seen the Earth and moon as whole worlds in space, in the same frame and in color.
Officials from the U.S. Geological Survey and Hawaii’s Civil Defense Agency flew over the new lava flow at Kilauea – Hawaii’s largest volcano – on September 15 and 16, 2014 to get a close up view of the eruption. Their observations have confirmed that the lava flow from Kilauea, which began on June 27, 2014, is continuing to advance in the northeast direction across the Big Island of Hawaii and has now entered a vacant portion of the Kahoe Homesteads.
Our friend Eileen Claffey captured this fogbow over a field in Massachusetts yesterday (September 17, 2014). She said it appeared as the fog was lifting over a field. Fogbows and rainbows are made from the same configuration of sunlight and moisture. That is, you see a fogbow in the direction opposite the sun. But fogbows are caused by the small droplets inside a fog or cloud rather than the larger raindrops that cause rainbows.
