TESS spacecraft finds its first Earth-sized planet around nearby star

Mon, 04/15/2019 - 04:00
The next generation of exoplanet hunting has arrived in the form of NASA’s Transiting Exoplanet and Survey Satellite. TESS looks at closer and brighter stars than Kepler, the spacecraft that first turned the trickle of exoplanet discoveries into a deluge. While TESS, which launched last year, is just beginning its sky search, it’s already started discovering new planets. Astronomers say they’ve discovered an Earth-sized planet dubbed HD 21749 c that sits just 52 light-years fro

Meteors slamming into the Moon reveal underground water

Mon, 04/15/2019 - 04:00
When NASA astronauts first landed on the Moon in 1969, they saw a desiccated world, bone-dry and devoid of any life-giving water. The Apollo astronauts, planning to stay only a few days, had brought plenty of water for their own needs. So this finding was disappointing for the hazy plans of future lunar outposts, but not immediately concerning. Decades later, humans have learned that the only economical way to explore space longterm is to use the resources we find along the way. And luckily, we&

Israel's Beresheet lander crashes into Moon

Thu, 04/11/2019 - 04:00
Israel’s Beresheet spacecraft, which was set to land on the Moon today, suffered an engine and communications failure, causing it to instead crash into the lunar surface. Details are still emerging about what exactly went wrong. Within the last five minutes or so of the landing procedure, mission control reported temporarily losing telemetry data before regaining it again. Shortly after, the main engine shut off, but engineers managed to restart it. Then, they reported a communications fai

It’s a monumental undertaking and if it succeeds, Beresheet and its creators will join the select ranks of those who have safely landed on the Moon – thus far only the United States, China, and the former Soviet Union. NASA and its Deep Space Network are aiding the mission in tra
