A brilliant orange flame cast against a sky of thick, gray clouds is captured in glorious new images of the launch of a SpaceX Falcon 9 rocket on Feb. 19.
For Houston, it will be a homecoming; for St. Louis, a product of its past. In Pittsburgh, it will be seen as a symbol of innovation; and in Seattle, an arrival worthy of a celebration.
SpaceX's Dragon cargo ship arrived at the International Space Station this morning after a 24-hour delay. Astronauts Thomas Pesquet and Shane Kimbrough grappled the cargo craft using the station's Canadarm2 robotic arm at 5:44 a.m. EST (1044 GMT).
A SpaceX Dragon cargo ship will rendezvous with the International Space Station today (Feb. 23), one day later than planned after a GPS navigation software issue prevented a docking on Wednesday. Watch Live here.
After waving off a docking attempt on Feb. 22nd, 2017 due to a software glitch, the SpaceX cargo spacecraft was successfully berthed to the International Space Station on Feb. 23. NASA PAO commentator Rob Navias makes the call.
The discovery of seven Earth-size worlds circling the nearby star TRAPPIST-1 could be a watershed moment in humanity's quest to find alien life, scientists say.
Come along for a tour of the remarkable TRAPPIST-1 system, which harbors seven planets about the same size of Earth.
A SpaceX Dragon cargo ship filled with tons of NASA supplies arrived at the International Space Station early Thursday (Feb. 23) after a one-day delay due to a navigation software glitch.
Scientists aren't the only ones excited about the discovery of seven Earth-size exoplanets around the star TRAPPIST-1. It turns out, the folks at Google are fans, too, and they celebrated with an adorable Google Doodle.
The discovery of seven Earth-size planets around a nearby star, TRAPPIST-1, is certainly exciting news. But what would it take to visit one of these potentially Earth-like alien worlds?
TRAPPIST-1, a small red-dwarf star, hosts at least seven rocky planets the size of Earth and smaller.
Snow plays an important role in Earth's water cycle, and NASA has launched a new initiative to investigate snow and its relationship to readily available liquid water.
NASA's first orbital spaceflight 55 years ago asked big questions about the unknowns of human spaceflight — many of which we're still asking today.
There's a powerful gamma-ray signal blasting from the massive galaxy's core, possibly revealing a compact region filled with annihilating dark matter particles.
The hunt for signs of life on seven exoplanets in the TRAPPIST-1 system, which lies just 39 light-years from Earth, will likely begin just a few years from now.
Scientists on NASA's New Horizons mission, which performed the first-ever flyby of Pluto in July 2015, will officially propose a new definition of "planet" next month — one that gives Pluto its planethood back.
Astronomers have never seen anything like this before: Seven Earth-size alien worlds orbit the same tiny, dim star, and all of them may be capable of supporting life as we know it, a new study reports.
On Feb. 22, 2017, scientists announced the discovery of TRAPPIST-1, an alien solar system with at least seven Earth-sized planets. See pictures of the discovery here.
An dwarf star named TRAPPIST-1, which is located about 39 light-years from Earth, harbors more planets than previously observed.
The NASA telescope sights were set on the system for 500 hours (about 21 days) and transits of the planets identified and characterized them. TRAPPIST-1 is 39 light years away and harbors 7 earth-sized planets.
