Two years ago, CfA astronomers reported the discovery of giant, twin lobes of gamma-ray emission protruding about 50,000 light-years above and below the plane of our Milky Way galaxy, and centered on the supermassive black hole at our galaxy’s core.The scientists
This few animations show the relative sizes of some planets and stars in our known Universe with VY Canis Majoris as the biggest known
From NASA Goddard Space Flight Center. NASA’s The Fermi Gamma-ray Space Telescope has been catching brief outbursts of high-energy light that are mysteriously produced above thunderstorms. The outbursts, known as terrestrial gamma-ray flashes (TGFs), last only a few
ESA’s Venus Express spacecraft orbited at 66 000 km above the Venus south pole and captured bright and dark cloud bands wind around the poles of Venus, staring down into the south polar vortex. Venus Express has been orbiting the planet since 2006. It carries seven
Launched on 5 July, Meteosat-10 is the latest satellite in the Meteosat Second Generation (MSG) series, which provides operational weather and climate monitoring services over Europe and Africa.In April 2013, Meteosat-9 will take over the Rapid Scanning Service (RSS)
A pulsar is a neutron star that emits beams of radiation that sweep through Earth’s line of sight. Like a black hole, it is an endpoint to stellar evolution. The “pulses” of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star’s
Observations of spectrometer data from NASA’s Mars Reconnaissance Orbiter (MRO) provide new evidence of a wet underground on Mars, NASA reported on January 20, 2013. Crater McLaughlin, the one under observation, is 57 miles (92 kilometers) in diameter and 1.4 miles
Spirit, MER-A (Mars Exploration Rover – A), is a robotic rover on Mars, active from 2004 to 2010. It was one of two rovers of NASA’s ongoing Mars Exploration Rover Mission. It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its
According to the press release issued on January 17, 2012 NASA demonstrated laser communication with a satellite by beaming image of Leonardo Da Vinci’s iconic painting Mona Lisa 240,000 miles to Lunar Reconnaissance Orbiter (LRO) orbiting the Moon. Lunar Orbiter
The “keys” to NASA’s Mars rovers are in the capable hands of the official rover drivers. Learn how they operate the vehicles from millions of miles away in this 60-second video from NASA’s Jet Propulsion Laboratory.Source:
