NASA spacecraft swings by moon, snaps 200,000 stars

NASA spacecraft swings by moon, snaps 200,000 stars

Technology
NASA's new planet-hunting spacecraft has successfully completed a flyby around the moon - snapping a photograph revealing more than 200,000 stars along the way. The picture is the first taken since the Transiting Exoplanet Survey Satellite (TESS) lifted off from Cape Canaveral in April on a SpaceX Falcon 9 rocket.TESS completed its lunar flyby on 17 May and the science team completed a two-second test exposure using one of the spacecraft's four cameras. Image: The new NASA image shows 200,000 stars It is centred on the southern hemisphere constellation Centaurus and reveals more than 200,000 stars.The picture is just the beginning for NASA, as TESS is expected to cover 400 times as much sky during its mission to search...

TESS snaps image of the stars as it swings by the moon en route to its final orbit

Science
May 18 (UPI) -- TESS, or the Transiting Exoplanet Survey Satellite, NASA's next-generation planet hunter, snapped a picture of the stars as it swung within 5,000 miles of the moon on Thursday, using the moon's gravity to fling itself toward its final orbit. With the feat, the spacecraft moved closer to the beginning of its scientific mission: photographing transiting exoplanets. The two-second test exposure, captured on Thursday, suggests the planet hunter's cameras are working properly. The plethora of stars in the image -- at least 2,000 of them -- showcases the broad perspective provided by TESS's four cameras. At the center of the image lies the southern constellation Centaurus. While TESS's scientific mission is largely the same as NASA's veteran planet hunter Kepler's -- to take im...
Plumes of ocean spray are emanating from Jupiter's moon Europa

Plumes of ocean spray are emanating from Jupiter's moon Europa

Science
May 14 (UPI) -- New research offers additional evidence of plumes emanating from Europa's subsurface ocean. Images captured by the Hubble Telescope have previously suggested the presence of ocean plumes ejected through tissues in the icy crust of Jupiter's moon. Some astronomers were skeptical of the Hubble results, however. The newest proof was discovered among data collected by the Galileo mission in 1997 during a Europa flyby. Scientists detailed the new proof in a paper published Monday in the journal Nature Astronomy. Scientists with the Cassini mission were able to identify water plumes protruding from Saturn's moon Enceladus by measuring perturbations in the magnetic fields surrounding the satellite. Molecules and atoms ejected in a watery plume quickly become ionized as solar win...

Earth's water present before impact formed moon, study finds

Science
March 29 (UPI) -- Based on an extensive collection of lunar and terrestrial samples, researchers have determined that most of the water on Earth was already present at the time of the impact that created the moon.Scientists from the United States, Britain and France studied moon rocks brought back to Earth by astronauts on the six Apollo missions and volcanic rocks retrieved from the ocean floor by Earth-bound scientists. They published their findings Thursday in the journal Science Advances."The research discovered only a small difference in oxygen composition between the lunar and terrestrial rocks," Dr. Richard Greenwood, a research fellow at The New University in England and lead author of the new study, said in a press release. "This demonstrates how well mixed all of the pieces of ro...
