With a deadly embrace, 'Spidery' pulsars consume their mates

Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.

NASA finds planet-sized space weather explosions on Venus

Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth’s magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they’re bigger than the entire planet and they can happen multiple times a day.

NASA's Curiosity adds reverse driving for wheel protection on Mars

Terrain that NASA's Curiosity Mars rover is now crossing is as smooth as team members had anticipated based on earlier images from orbit. On Tuesday, Feb. 18, the rover covered 329 feet (100.3 meters), the mission's first long trek that used reverse driving and its farthest one-day advance of any kind in more than three months.

NASA's NuSTAR untangles mystery of how stars explode

One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR).

NASA responds to potential asteroid redirect mission targets

One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb.

IBEX helps paint picture of the magnetic system beyond the solar wind

Understanding the region of interstellar space through which the solar system travels is no easy task. Interstellar space begins beyond the heliosphere, the bubble of charged particles surrounding the sun that reaches far beyond the outer planets. Voyager 1 has crossed into this space, but it’s difficult to gain a complete global picture from measurements in only one direction.

NASA moves longest-serving Mars spacecraft for new observations

NASA's Mars Odyssey spacecraft has tweaked its orbit to help scientists make the first systematic observations of how morning fogs, clouds and surface frost develop in different seasons on the Red Planet.

NASA's Curiosity rover drives on after crossing Martian dune

NASA's Curiosity Mars rover is continuing its traverse toward enticing science destinations after climbing over a dune spanning a gap in a ridge.

NASA spacecraft get a 360-degree view of Saturn's auroras

NASA trained several pairs of eyes on Saturn as the planet put on a dancing light show at its poles. While NASA's Hubble Space Telescope, orbiting around Earth, was able to observe the northern auroras in ultraviolet wavelengths, NASA's Cassini spacecraft, orbiting around Saturn, got complementary close-up views in infrared, visible-light and ultraviolet wavelengths. Cassini could also see northern and southern parts of Saturn that don't face Earth.

NASA wants better batteries for electric vehicles

Electricity producing batteries are a vital part of daily life on Earth and in space. Power storage devices keep spacecraft operating, cars running, cell phones connected and flashlights lit. The Advanced Research Projects Agency-Energy (ARPA-E) now is funding 22 projects across 15 states with a total of $36 million to develop better, more efficient power sources for electric vehicles (EV).

NASA Mars Orbiters spots clues to possible water flows

NASA spacecraft orbiting Mars have returned clues for understanding seasonal features that are the strongest indication of possible liquid water that may exist today on the Red Planet.

NASA completes radar study of Icelandic glacier movement

The cold of an Icelandic winter did not stop one NASA science aircraft from completing a mission to map glaciers on the island during the past week. NASA's C-20A, based at the Dryden Aircraft Operations Facility in Palmdale, Calif., flew four radar missions from Keflavik International Airport near Reykjavik, Iceland.

Looking back to the cradle of our Universe

NASA's Spitzer and Hubble Space Telescopes have spotted what might be one of the most distant galaxies known, harkening back to a time when our universe was only about 650 million years old (our universe is 13.8 billion years old). The galaxy, known as Abell2744 Y1, is about 30 times smaller than our Milky Way galaxy and is producing about 10 times more stars, as is typical for galaxies in our young universe.

WASP gives NASA's planetary scientists new observation platform

Scientists who study Earth, the sun and stars have long used high-altitude scientific balloons to carry their telescopes far into the stratosphere for a better view of their targets. Not so much for planetary scientists. That's because they needed a highly stable, off-the-shelf-type system that could accurately point their instruments and then track planetary targets as they moved in the solar system.

NASA's Mars Orbiter spots dramatic new crater

Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.

NASA boards the 3D-manufacturing train

Given NASA's unique needs for highly custom­ized spacecraft and instrument components, additive manufacturing, or "3-D printing," offers a compelling alternative to more traditional manufacturing approaches.

NASA's Mars Rover eyes possible westward route

NASA's Curiosity Mars rover reached the edge of a dune on Jan. 30 and photographed the valley on the other side, to aid assessment of whether to cross the dune.

Searching space dust for life's ingredients

While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life. Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life.

NASA's Curiosity Mars Rover checks for smoother route

The team operating NASA's Mars rover Curiosity is considering a path across a small sand dune to reach a favorable route to science destinations. A favorable route would skirt some terrain with sharp rocks considered more likely to poke holes in the rover's aluminum wheels.

Where the wild stars are

A storm of stars is brewing in the Trifid nebula, as seen in this view from NASA's Wide-field Infrared Survey Explorer, or WISE. The stellar nursery, where baby stars are bursting into being, is the yellow-and-orange object dominating the picture. Yellow bars in the nebula appear to cut a cavity into three sections, hence the name Trifid nebula.
