A two-stage SpaceX Falcon 9 rocket lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida for Demo-1, the first uncrewed mission of the agency’s Commercial Crew Program. The on-time liftoff occurred at 2:49 a.m., Saturday, March 2, 2019. Photo credit: NASA

SpaceX Crew Dragon spacecraft launched

For the first time in history, a commercially-built and operated American crew spacecraft and the rocket is underway to the International Space Station, following...
NASA's Curiosity Mars took this image with its Mastcam on Feb. 10, 2019 (Sol 2316). The rover is currently exploring a region of Mount Sharp nicknamed "Glen Torridon" that has lots of clay minerals. Credits: NASA/JPL-Caltech/MSSS

After a reset, Curiosity is operating normally

On Feb 13, NASA's Opportunity rover on Mars was declared ‘dead’, leaving Curiosity as NASA’s only functioning rover left on the planet Mars. Now,...
This image shows the merger of two galaxies, known as NGC 7752 (larger) and NGC 7753 (smaller), also collectively called Arp86. In these images, different colors correspond to different wavelengths of infrared light. Blue and green are wavelengths both strongly emitted by stars. Red is a wavelength mostly emitted by dust.

Why do some galactic unions lead to doom?

NASA's Spitzer Space Telescope recently releases some pictures that show pairs of galaxies on the cusp of cosmic consolidations. Even though the galaxies appearing...
Research using data from NASA's ARTEMIS mission suggests that lunar swirls, like the Reiner Gamma lunar swirl imaged here by NASA's Lunar Reconnaissance Orbiter, could be the result of solar wind interactions with the Moon's isolated pockets of magnetic field. Credits: NASA LRO WAC science team

NASA mission reveals origins of Moon’s ‘Sunburn’

What happens when the Sun’s radiation hits our rocky moon, where there is no magnetic field to protect it. Scientists used NASA's ARTEMIS mission and...
An image of Saturn's moon Enceladus backlit by the Sun, taken by the Cassini mission. The false color tail shows jets of icy particles and water that spray into space from an ocean that lies deep below the moon's icy surface. Future missions could search for the ingredients for life in an ocean on an icy moon like Enceladus. Credits: NASA/JPL/Space Science Institute

Study reproduces origins of life on ocean floor

Since years, scientists believe that life originated in the oceans, as the primary divisions and the events of evolution took place there. Now, NASA...
The most detailed images of Ultima Thule -- obtained just minutes before the spacecraft's closest approach at 12:33 a.m. EST on Jan. 1 -- have a resolution of about 110 feet (33 meters) per pixel. Their combination of higher spatial resolution and a favorable viewing geometry offer an unprecedented opportunity to investigate the surface of Ultima Thule, believed to be the most primitive object ever encountered by a spacecraft. This processed, composite picture combines nine individual images taken with the Long Range Reconnaissance Imager (LORRI), each with an exposure time of 0.025 seconds, just 6 ½ minutes before the spacecraft’s closest approach to Ultima Thule (officially named 2014 MU69). The image was taken at 5:26 UT (12:26 a.m. EST) on Jan. 1, 2019, when the spacecraft was 4,109 miles (6,628 kilometers) from Ultima Thule and 4.1 billion miles (6.6 billion kilometers) from Earth. The angle between the spacecraft, Ultima Thule and the Sun – known as the “phase angle” – was 33 degrees.

The sharpest views of Ultima Thule

The scientists behind NASA’s New Horizons spacecraft have released the sharpest possible view of the Ultima Thule. Just before making the closest approach to...

Moon could be a chemical factory for water

Using a computer program, NASA scientists have recreated a chemical procedure through which elements for water could be made on the surface of the...
Bright green sources of high-energy X-ray light captured by NASA's NuSTAR mission are overlaid on an optical-light image of the Whirlpool galaxy (in the center of the image) and its companion galaxy, M51b (the bright greenish-white spot above the Whirlpool), taken by the Sloan Digital Sky Survey.Credit: NASA/JPL-Caltech, IPAC

In colliding galaxies, a pipsqueak shines bright

In the nearby Whirlpool galaxy and its companion universe, M51b, two supermassive black holes heat up and devour encompassing material. These two beasts ought...
This artist’s impression shows the outermost planet of the Solar System, Neptune, and its small moon Hippocamp. Hippocamp was discovered in images taken with the NASA/ESA Hubble Space Telescope. Whilst the images taken with Hubble allowed astronomers to discover the moon and also to measure its diameter, about 34 kilometres, these images do not allow us to see surface structures.

Hubble helps uncover origin of Neptune’s smallest moon Hippocamp

Astronomers using the NASA/ESA Hubble Space Telescope, along with older data from the Voyager 2 probe, have revealed more about the origin of Neptune’s...
