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.
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
Cosmic winds that form the long tentacles of jellyfish galaxies may also create the perfect conditions to sustain highly active supermassive black holes
(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 Lunar Reconnaissance Orbiter (LRO) team invites the public to wave at the Moon on Aug. 21 as LRO turns its camera toward Earth.

Ronald Dantowitz has been looking forward to Monday's solar eclipse for nearly 40 years.
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.
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
"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...
(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
Next week's solar eclipse will reveal the Sun's corona, nearby bright planets and stars, and, if we get extremely lucky, a comet!
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

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.
Human spaceflight and robotic exploration image of the week: Expedition 52/53 crew on the International Space Station
A SpaceX shipment arrived at the International Space Station on Wednesday, delivering a bonanza of science experiments.
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.
In parts of the United States, the eclipse will occur around lunchtime. Consider planning a picnic. (At least, have a crescent-shaped cookie.)
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
