On Aug. 17, 2017, weak ripples in the fabric of space-time known as gravitational waves washed over Earth. Unlike previously detected gravitational waves, these were accompanied by light, allowing astronomers to pinpoint the source. NASA’s Hubble Space Telescope turned its powerful gaze onto the new beacon, obtaining both images and spectra. The resulting data will help reveal details of the titanic collision that created the gravitational waves, and its aftermath.News Article Type: Homepage ArticlesPublished: Wednesday, October 18, 2017 - 10:32

The answer is one 1 astronomical unit. How far is that?
Two methods that scientists use to measure the expansion of the universe produce different answers. A recent episode of NASA's ScienceCasts video series explores this conundrum.
Heat and light from the sun make life on Earth possible.
Astronomers have pinpointed five pairs of merging black holes using three different space and ground-based instruments and two sky surveys.
After spending months or years in space during future long-term missions, returning to Earth can be challenging for astronauts — and one set of researchers is finding out just how challenging using a life-size spacecraft model.
For the first time ever, scientists around the world detected gravitational waves and light from the collision of a pair of neutron stars. See the epic discovery in pictures here.
Four trailblazing figures from NASA's history are set to launch as new Lego minifigures. As-tronauts Sally Ride and Mae Jemison, as well as programmer Margaret Hamilton and astrono-mer Nancy Grace Roman, feature in the Lego Ideas set, "Women of NASA."
A new market for super high-speed weapons is fueling investments in rocket engine technologies as companies seek to gain an edge.
General Atomics is better known for building Predator combat drones and mining uranium than building spacecraft, but that could change as the company develops an interest in building defense-focused cubesats.
An international team of astronomers detected the first gravitational waves from merging neutron stars, and found proof they are the source of the universe's heavy elements, including gold and platinum.
Mission control on earth receives an urgent communication from Mars that an astronaut has fractured his shinbone. Using a handheld scanning device, the crew takes images of his damaged tibia and transmits them to earth.
A shift in focus in NASA's exploration plans to the moon won't have an immediate effect on planning for the first flight of the agency's Space Launch System rocket, now expected no sooner than late 2019.
