The dazzling Perseid meteor shower has not yet reached its peak, but NASA cameras planted on the ground in the United States have already witnessed some early fireballs streaking across the summer... sky.

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near... the black hole, called the corona, has moved closer to the black hole over a period of just days.

Apollo 11 moonwalker Buzz Aldrin paid his respects to comedian Robin Williams today with a post on Facebook. The Oscar-winning actor was found dead of an apparent suicide in his home in California on... Monday (Aug. 11). He was 63 years old.

Who doesn't love an upgrade? Newer, better and oh so shiny is great, but what's really fantastic is when a change unlocks new possibilities. That's the case with NASA's fix-it investigation on the... International Space Station, the Robotic Refueling Mission (RRM). The award-winning endeavor moved one step closer to its 2.0 update with the delivery of new RRM hardware aboard the European Automated Transfer Vehicle-5, which docked with the space station today. The RRM module, affixed to an exterior space station platform since 2011, now awaits the robotic transfer of two new task boards and a borescope inspection tool that will equip RRM for a new round of satellite-servicing demonstrations.

Of all species that have existed on Earth, 99.9 percent are now extinct. Many of them perished in five cataclysmic events. The classical "Big Five" mass extinctions identified by Raup and Sepkoski are... widely agreed upon as some of the...

Google is paying tribute to the annual Perseid meteor shower -- peaking tonight (Aug. 12) -- with a special doodle honoring the usually spectacular cosmic display.

The actor/comedian recorded a wake-up call for the STS-26 crew that was relayed on September 30th, 1988 by CAPCOMs Kathy Sullivan (standing) and Kathy Thornton (seated on console). Full Story:... ://goo.gl/cQDaQN

Michael Gass, the former Lockheed Martin executive who has led United Launch Alliance since the Boeing-Lockheed Martin joint venture was created in 2006, has been replaced as president and chief... executive officer and will retire at the end of this year

I firmly believe that our next greatest discovery will be detecting an exomoon in orbit around a distant exoplanet. Although no one has been able to confirm an exomoon -- yet -- the hunt is on. Now, a... research team thinks following a trail of radio wave emissions may lead astronomers to this groundbreaking discovery. […]

The international Cassini-Huygens mission scanned a gathering cloud mass over the methane sea known as Ligeia Mare on Saturn's largest moon Titan between July 20th and 22nd 2014.

The annual best-of-summer meteor shower peaks late Tuesday and into the wee hours Wednesday morning.

Swoosh! At long last, and later than models predicted, clouds are starting to appear on Titan’s nothern hemisphere. The region is just starting to enter a seven-year-long summer, and scientists... say this could be an indication of coming summer storms there. This moon of Saturn is of particular interest to astrobiologists because it has hydrocarbons […]

As NASA's Cassini spacecraft sped away from Titan following a relatively close flyby, its cameras monitored the moon's northern polar region, capturing signs of renewed cloud activity....

On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away--which would be like a comet passing about 1/3 of the distance between Earth and the Moon.

NASA's Jet Propulsion Laboratory News and Features: A supermassive black hole is grabbing and stretching light to an extreme degree never seen before.

An extraordinary amount of ultraviolet light appears to be missing from the universe, scientists have found.One potential source of this missing light might be the mysterious dark matter that makes up... most of the mass in the cosmos.

Scientists have used NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), an orbiting X-ray telescope, to capture an extreme and rare event in the regions immediately surrounding a supermassive... black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the black hole over a period of just days. The researchers publish their results in Monthly Notices of the Royal Astronomical Society. An artist's impression of a supermassive black hole and its surroundings. The regions around supermassive black holes shine brightly in X-rays. Some of this radiation comes from a surrounding disk, and most comes from the corona, pictured here as the white light at the base of a jet. This is one possible configuration for the Mrk 335 corona, as its...

NASA's Jet Propulsion Laboratory News and Features: NASA's Cassini spacecraft recently captured images of clouds moving across the northern hydrocarbon seas of Saturn's moon Titan.

The U.S. Navy has honored the nation's first woman in space, christening its new ocean research ship after the late astronaut Sally Ride.

Hylas 4 will deliver up to 28 gigahertz of throughput to 66 fixed beams plus four steerable beams.

Here's a great video from a camera mounted on the exterior of the TechDemoSat-1, an in-orbit technology demonstration mission from the UK. It launched on July 8, 2014 on a Soyuz-2, and the video shows... the satellite moments after separation from the upper stage. The satellite even took a selfie, below. The video shows the […]

TechDemoSat-1 was launched on July 8th, 2014 aboard a Soyuz-2 launch vehicle. Its inspection camera captured the Soyuz upper stage (gold object) and another satellite it was launched with (white dot @... 34 seconds) over the Pacific Ocean.
