Three-dimensional printers are transforming the business, medical, and consumer landscape by creating a vast variety of objects, including airplane parts, football cleats, lamps, jewelry, and even artificial human bones.
A team of scientists led by astronomers at the University of California, Riverside has used NASA's Hubble Space Telescope to uncover the long-suspected underlying population of galaxies that produced the bulk of new stars during the universe's early years.
An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.
A newly discovered system of two white dwarf stars and a superdense pulsar–all packed within a space smaller than the Earth’s orbit around the sun–is enabling astronomers to probe a range of cosmic mysteries, including the very nature of gravity itself.
Galaxies can be remarkably dusty places and supernovas are thought to be a primary source of that dust, especially in the early Universe. Direct evidence of a supernova's dust-making capabilities, however, has been slim and cannot account for the copious amount of dust detected in young, distant galaxies.
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) have discovered a unique stellar system of two white dwarf stars and a superdense neutron star, all packed within a space smaller than Earth's orbit around the Sun.
Several sources confirm that the first discovered asteroid in 2014, designated 2014 AA, entered Earth’s atmosphere late Jan. 1 (Jan. 2 Universal time) over the mid-Atlantic Ocean.
Eighth graders didn't have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning's Channel One news in her Fredericksburg, Texas, classroom caught her eye.
Climbing robots that mimic the stickiness of gecko lizard feet could work in space as well as on Earth, ESA has shown, raising the prospect of hull-crawling automatons tending future spacecraft.
The second year of an unprecedented balloon campaign in Antarctica has just begun. The NASA-funded mission – called the Balloon Array for Radiation belt Relativistic Electron Losses, or BARREL – is led by Dartmouth College in Hanover, N.H. The mission is unique, as it relies not on one gigantic balloon, but on many smaller ones, 20 in total.
China's Chang'e 3 landed on Mare Imbrium (Sea of Rains) just east of a 450 m diameter impact crater on 14 December 2013. Soon after landing, a small rover named Yutu (or Jade Rabbit in English) was deployed and took its first tentative drive onto the airless regolith.
Weather forecasters on exoplanet GJ 1214b would have an easy job. Today's forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds.
Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery gives strong support for one of the competing explanations for how double-star systems form.
Located some 25 million light-years away, this new Hubble image shows spiral galaxy ESO 373-8. Together with at least seven of its galactic neighbors, this galaxy is a member of the NGC 2997 group. We see it side-on as a thin, glittering streak across the sky, with all its contents neatly aligned in the same plane.
The NASA Wallops Flight Facility and Virginia’s Mid-Atlantic Regional Spaceport are set to support the launch of Orbital Sciences’ Corp. Antares rocket at 1:55 p.m. EST, Jan. 7. The Antares rocket will carry Orbital’s Cygnus cargo spacecraft to the International Space Station.
To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system. To determine if any of these far-off worlds are habitable requires knowing an exoplanet’s mass — which can help tell scientists whether the planet is made of gas or rock and other life-supporting materials.
Late this month, ESA’s Mars Express will make the closest flyby yet of the Red Planet’s largest moon Phobos, skimming past at only 45 km above its surface.
Environmental research and weather forecasting are about to get a significant technology boost as NASA and the Japan Aerospace Exploration Agency (JAXA) prepare to launch a new satellite in February.
A NASA observatory that will make the most precise, highest-resolution and most complete, space-based measurements of carbon dioxide in Earth's atmosphere to date has marked a key milestone in preparation for its planned July 2014 launch.
When satellites reach the end of their working lives, they may pose a threat to other spacecraft as they continue to orbit in a dormant state for many decades. But now a new way to deorbit ageing satellites in a safe manner is nearing its first test in space.
