The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos.
Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour — so fast it could travel the distance between Earth and the Moon in just 6 minutes.
A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid’s surface.
Telesat and Blue Origin have signed a multi-launch agreement that paves the way for the powerful New Glenn rocket to play a key role in Telesat’s deployment of its global LEO satellite constellation that will deliver fiber-like broadband services anywhere on Earth.
The SpaceX Dragon cargo craft had its stay extended at the International Space Station a few more days. Mission managers observed inclement weather at Dragon’s splashdown site in the Pacific Ocean and decided against Dragon’s return to Earth today.
The December 2018 close approach by the large, near-Earth asteroid 2003 SD220 has provided astronomers an outstanding opportunity to obtain detailed radar images of the surface and shape of the object and to improve the understanding of its orbit.
NASA’s InSight lander is due to set its first science instrument on Mars in the coming days But engineers here on Earth already saw it happen — last week.
Before a NASA technology makes it to orbit or lands on another planet, researchers test – and retest – it in space-like conditions. These tests often take place on Earth, but some payloads take a trip to suborbital space for a few minutes of valuable microgravity testing.
Some night skies are serene and passive — others shimmer and flash. The later, in the form of auroras and meteors, haunted skies over the island of Kvaløya, near Tromsø Norway on 2009 December 13. This 30 second long exposure records a shimmering auroral glow gently lighting the wintery coastal scene.
One of the most spectacular meteor showers is making its annual return on Thursday night. The Geminid meteor shower occurs every December, when the Earth passes through the tail of debris from a 3-mile-wide rocky object in space named 3200 Phaethon.
For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.
As local, federal, and international policies targeting the quality of the air we breathe continue to evolve, questions arise of how effective existing policies have been in improving human health.
This Hubble Space Telescope mosaic is of a portion of the immense Coma cluster of over 1,000 galaxies, located 300 million light-years from Earth.
NASA’s InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA’s Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST).
An international team of researchers, including a NASA glaciologist, has discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in northwest Greenland.
Shadows on Earth can be mysterious and foreboding, but when they occur in space, they can convey information we otherwise could not know. In a stellar nursery called the Serpens Nebula, nearly 1,300 light-years away, a young star’s game of shadow play is revealing secrets of its unseen planet-forming disk.
This image from NASA’s Spitzer Space Telescope shows the Cat’s Paw Nebula, so named for the large, round features that create the impression of a feline footprint. The nebula is a star-forming region in the Milky Way galaxy, located in the constellation Scorpius. Estimates of its distance from Earth range from about 4,200 to about 5,500 light-years.
