official news from : https://bit.ly/2QkyIbY This NASA/ESA Hubble Space Telescope image features a spiral galaxy, named UGC 10043. We don’t see the galaxy’s spiral arms because we are seeing it from the side. Located roughly 150 million light-years from Earth in the constellation Serpens, UGC 10043 is one of the somewhat rare spiral galaxies thatContinue reading “Hubble Captures an Edge-On Spiral with Curve Appeal”

The International Space Station is humanity’s home in space and a research station orbiting about 250 miles above the Earth. NASA and its international partners have maintained a continuous human presence aboard the space station for more than 24 years, conducting research that isContinue reading “FAQ: The Real Story About Astronaut Health Care in Space”

official news from : https://bit.ly/2QkyIbY This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations forContinue reading “Ring Around Tabby’s Star”

official news from : https://bit.ly/2QkyIbY NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before.  The animation shows the strength of the turbulent motionsContinue reading “Ready, Set, Action!

official news from : https://bit.ly/2QkyIbY In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our Sun. Unlike an exploding star though, it has declined inContinue reading “NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis”

official news from : https://bit.ly/2QkyIbY The mystery of why life uses molecules with specific orientations has deepened with a NASA-funded discovery that RNA — a key molecule thought to have potentially held the instructions for life before DNA emerged — can favor making the building blocks of proteins in either the left-hand or the right-handContinue reading “NASA: Mystery of Life’s Handedness Deepens”
