NASA protects its super heroes from space weather

It's not a bird or a plane but it might be a solar storm. We like to think of astronauts as our super heroes, but the reality is astronauts are not built like Superman who gains strength from the sun. In fact, much of the energy radiating from the sun is harmful to us mere mortals.

TDRS: An era of continuous space communications

More than 50 years ago, at the dawn of human spaceflight, the first brave astronauts were only able to communicate with mission control operators on Earth for about 15 percent of each orbit. If this were true today, the International Space Station would only be in contact with the ground for less than 15 minutes out of its 90-minute orbit. Show More Summary

Jellyfish galaxies may feed black holes with their long tendrils

Cosmic winds that form the long tentacles of jellyfish galaxies may also create the perfect conditions to sustain highly active supermassive black holes

TDRS: An era of continuous space communications

(NASA/Goddard Space Flight Center) When NASA created Tracking and Data Relay Satellite system in the 1980s, it revolutionized space communications. As NASA launches the 13th TDRS satellite, it looks forward to the next communications innovation.

NASA's LRO team wants you to wave at the moon

NASA's Lunar Reconnaissance Orbiter (LRO) team invites the public to wave at the Moon on Aug. 21 as LRO turns its camera toward Earth.

Can't see the solar eclipse? Tune in online or on TV

Ronald Dantowitz has been looking forward to Monday's solar eclipse for nearly 40 years.

?ould life begin in oil?

Paul Bracher, Ph.D., assistant professor in the department of chemistry at Saint Louis University, and his research team have been awarded a three-year $597,380 grant from the National Science Foundation (NSF) to study what life might look like on other planets - or, here on earth - if it began in oil.

Supermassive black holes feed on cosmic jellyfish

An Italian-led team of astronomers used the MUSE (Multi-Unit Spectroscopic Explorer) instrument on the Very Large Telescope (VLT) at ESO's Paranal Observatory in Chile to study how gas can be stripped from galaxies. They focused on extreme...Show More Summary

A New Look At the 1977 WOW! Signal 6EQUJ5 --A Message from the 'Cosmic Watering Hole'? (VIEW Today's 'Galaxy' Stream)

"If those civilizations are out there – and we don't know that they are – those that inhabit star systems that lie close to the plane of the Earth's orbit around the sun will be the most motivated to send...        

Harnessing rich satellite data to estimate crop yield

(University of Illinois College of Agricultural, Consumer and Environmental Sciences) Without advanced sensing technology, humans see only a small portion of the entire electromagnetic spectrum. Satellites see the full range -- from high-energy gamma rays, to visible, infrared, and low-energy microwaves. Show More Summary

Could the total solar eclipse reveal a comet?

Next week's solar eclipse will reveal the Sun's corona, nearby bright planets and stars, and, if we get extremely lucky, a comet!

Mars 2020 mission to use smart methods to seek signs of past life

NASA's Mars 2020 mission, which will look for signs of past life on Mars, will use smart methods originally developed to find the oldest life on Earth, according the mission's Deputy Project Scientist, Dr Ken Williford. The 2020 mission...Show More Summary

Image: Gaia's first full-colour all-sky map

While surveying the positions of over a billion stars, ESA's Gaia mission is also measuring their colour, a key diagnostic to study the physical properties of stars. A new image provides a preview of Gaia's first full-colour all-sky map, which will be unleashed in its highest resolution with the next data release in 2018.

A SpaceX shipment arrived at the International Space Station on Wednesday, delivering a bonanza of science experiments.

Radio relic discovered in a low-mass merging galaxy cluster

Astronomers have detected a new single radio relic in a low-mass merging galaxy cluster known as PLCK G200.9?28.2. The finding, presented Aug. 5 in a paper published on the arXiv pre-print server, could offer some hints about merging processes in galaxy clusters.

Meals for Your Eclipse Menu

In parts of the United States, the eclipse will occur around lunchtime. Consider planning a picnic. (At least, have a crescent-shaped cookie.)

Team redefines cosmic velocity web

The cosmic web—the distribution of matter on the largest scales in the universe—has usually been defined through the distribution of galaxies. Now, a new study by a team of astronomers from France, Israel and Hawaii demonstrates a novel approach. Show More Summary
