New NASA program called Scout could detect objects in space near Earth and calculate their potential risk. ...

At a Glance A computer program being developed by NASA will act as an asteroid intruder alert.The program, Scout, detects Near Earth Objects and calculates the potential risk. Scout detected a possible threat this month. The possibility of an asteroid colliding with the Earth is a threat that scientists have become increasingly interested in avoiding. A computer program called Scout is helping them keep an eye out. Scout is essentially to determine if there are any reports of Near Earth...

The image above is an artist's rendition of exoplanet HD 189733 b. Scientists say its light blue hue is caused by its nightmarish weather conditions. (ESO/M. Kornmesser) At a Glance Exoplanet HD 189733 b may look like Earth from a distance, but is a nightmarish alien world up close.Astronomers say the planet's weather features deadly winds and "rains of terror." A far-off exoplanet circling the Earth may appear to be a bright blue similar to the hues of our home...

It turns out the white stuff visible on the satellite is known as glacial flour because it resembles the kind you cook with. Meteorologist Ari Sarsalari explains why this only happens at certain times of the year. ...

At a Glance The "Beaver" supermoon will be the largest in almost 70 years.The moon won't come this close to Earth again until 2034. Sky gazers are about to be treated to a celestial event that won't come again for many years to come. The "record-breaking" supermoon slated for Nov. 14, known as the Beaver Moon or Frost Moon, will be the largest in almost 70 years, will appear exceptionally large and bring with it higher than normal tides. November's...

The image above shows massive stars slowly destroying the pillars of dust and gas from which they are born in the star formation region R44 in the Carina Nebula. At a Glance Images captured by the European Space Observatory show "pillars of destruction" as stars destroy the region in which they were born. The structures are in contrast to the iconic Pillars of Creation in the Eagle Nebula. Researchers are still learning the intricacies of the feedback mechanisms between the...

JPL developed a proof of concept for robotic microspines that can anchor to and core surfaces regardless of gravitational orientation. ...

This image of Saturn and its rings was taken by NASA's Cassini spacecraft. (NASA/JPL/Space Science Institute) At a Glance A new study has found that Saturn's rings likely formed during a period of heavy bombardment some four billion years ago.The rings may be composed of fragments of thousands of dwarf planets, which invaded the solar system from its outer edges. Humans have been mesmerized by Saturn's iconic rings for centuries, but astronomers have long studied how they formed without a...

The LES1 satellite that was once lost has come back to life. ...

At a Glance LES1 never reached its intended orbit due to a launch failure.It remains a mystery why the satellite resumed sending signals after 46 years. An American satellite left for dead as space junk almost 50 years ago has come alive again, transmitting signals back to earth. According to NASA, — LES1 through LES9 — designed and built by Lincoln Laboratory between 1965 and 1976. The purpose of the unmanned space crafts was to test techniques for military satellite...

Astronomers say they’ve never seen anything like it, a supermassive black hole, naked and alone and hurtling through the universe at 2,000 miles per second. ...

A NASA satellite that’s orbiting Mars has sent back pictures of the site where a European spacecraft crashed on the Red Planet. ...
