On 24 April 2015 a 7.9 magnitude earthquake struck Nepal - a nation woefully unprepared to respond to such an event. Nearly 300 aftershocks of magnitude 4.0 or greater have rattled the country for the past month.

Long, sinuous, tendril-like structures seen in the vicinity of Saturn's icy moon Enceladus originate directly from geysers erupting from its surface, according to scientists studying images from NASA's Cassini spacecraft.

Since its capture by the gravity of dwarf planet Ceres on March 6, NASA's Dawn spacecraft has performed flawlessly, continuing to thrust with its ion engine as planned.

A new high-energy X-ray image from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has pinpointed the true monster of a galactic mashup. The image shows two colliding galaxies, collectively called Arp 299, located 134 million light-years away. Each of the galaxies has a supermassive black hole at its heart.

NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8, 2014, the new views of the object designated "2014 HQ124" are some of the most detailed radar images of a near-Earth asteroid ever obtained.

Images taken by NASA's Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the sun glinting off a rock or cosmic rays striking the camera's detector.

JPL's RoboSimian

Miami Speedway in Homestead, Fla., was the place to be late last month for an unusual two-day competition: the DARPA Robotics Challenge Trials.

Curiosity Drills Second Rock Target

NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland."

Opportunity is in Standby Mode

During a moratorium on commanding this month while Mars passed nearly behind the sun - a phase called solar conjunction -- NASA's Mars Exploration Rover Opportunity entered a type of standby mode.

A gauge on the Voyager home page tracks levels of two of the three key signs scientists believe will appear when the spacecraft leave our solar neighborhood and enter interstellar space. When the three signs are verified, scientists will know that one of the Voyagers has hurtled beyond the magnetic bubble the sun blows around itself, which is known as the heliosphere.

An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar.

A Storm on Saturn Chokes on Its Own Tail

Call it a Saturnian version of the Ouroboros, the mythical serpent that bites its own tail.

The NASA Mars Exploration Rover Opportunity is beginning its 10th year roving Mars, completing nine years of "shocking" performance and historic discoveries that began with a bouncing airbag roll into tiny Eagle crater on Jan. 24, 2004.

Titan's siblings must be jealous. While most of Saturn's moons display their ancient faces pockmarked by thousands of craters, Titan -- Saturn's largest moon -- may look much younger than it really is because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research using observations from NASA's Cassini spacecraft.

NASA scientists have announced that new observations of 2011 AG5 show that this asteroid, once thought to have a worrisome potential to threaten Earth, no longer poses a significant risk of impact.

Radar Images of Asteroid Toutatis

Sequences of Goldstone delay-Doppler radar images of Toutatis from the 2012 observing campaign. In each image, range increases down and Doppler frequency increases toward the right, so rotation is counterclockwise.

Radar Images of Asteroid 2007 PA8

A collage shows nine radar images of near-Earth asteroid 2007 PA8 that were obtained between Oct. 31 and Nov. 13, 2012, with data collected by NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif.

Forecasters could soon be better able to predict how intense tropical cyclones like Hurricane Sandy will be by analyzing relative-humidity levels within their large-scale environments, finds a new NASA-led study.

NASA's car-sized rover, Curiosity, has taken significant steps toward understanding how Mars may have lost much of its original atmosphere.

Dawn Sees 'Young' Surface on Vesta

Like a Hollywood starlet constantly retouching her makeup, the giant asteroid Vesta is constantly stirring its outermost layer to present a young face. Data from NASA's Dawn mission show that a form of weathering that occurs on the moon and other airless bodies we've visited in the inner solar system does not alter Vesta's outermost layer in the same way.
