The moon likely had an ancient, temporary atmosphere — similar to the pocket of gases that surround Earth — around 3 to 4 billion years ago, according to a new study. Scientists at NASA’s Marshall Space Flight Center and the Lunar and Planetary Institute (LPI) in Houston found that the atmosphere was caused by ancient […]Read more "The Moon Once Had an Atmosphere"
Thanks to an amplified image produced by a gravitational lens, and the Gran Telescopio CANARIAS, a team of scientists has discovered one of the brightest galaxies known from the epoch when the universe had 20 percent of its present age. Astronomers have discovered possibly the most luminous ‘new star’ ever — a nova discovered in […]Read more "Scientists spot one of the brightest New Stars Ever"
The aurora is an incredible light show caused by collisions between gaseous particles with charged particles. Variations in color are due to the type of gas particles that are colliding. The most common aurora color which is green, is produced by oxygen molecules located about 60 miles above the earth.Read more "The Aurora"
The Expedition 53 crew members continued testing a new exercise device today while also exploring how their bodies are adapting to living in space. The station residents are also gearing up for three spacewalks planned in October. Commander Randy Bresnik joined Paolo Nespoli for a workout session on the new Miniature Exercise Device-2 (MED-2). The […]Read more "Astronauts Research Adapting to Space and Plan for Spacewalks"
AFP reports the US and Russia will work together on a NASA program to build the Deep Space Gateway, a space station in orbit around the moon. NASA and Russia’s Roscosmos signed an agreement to cooperate on the station—which will be “an invaluable pit stop for human and robotic exploration of the lunar surface” and […]Read more "Russia and the US plan a lunar space station"
NASA’s Cassini spacecraft ended a nearly 20-year mission Sept. 15 with a plunge into the atmosphere of the planet Saturn intended to protect the planet’s potentially habitable moons from contamination. The last signals from the Cassini spacecraft arrived at NASA’s Deep Space Network antennas near Canberra, Australia, at 7:55 a.m. Eastern, 83 minutes after the […]Read more "Cassini Mission Ends"
Six NASA-backed research subjects who have been cooped up in a Mars-like habitat on a remote Hawaii volcano since January emerged from isolation Sunday. They devoured fresh-picked tropical fruits and fluffy egg strata after eating mostly freeze-dried food while in isolation and some vegetables they grew during their mission. The crew of four men and […]Read more "Mars Research Crew Emerge"
