Cassini completes final -- and fateful -- Titan flyby: Dive to Saturn next
NASA's Cassini spacecraft has had its last close brush with Saturn's hazy moon Titan and is now beginning its final set of 22 orbits around the ringed planet.

Lull in Mars' giant impact history
From the earliest days of our solar system's history, collisions between astronomical objects have shaped the planets and changed the course of their evolution. Studying the early bombardment history of Mars, scientists have discovered a 400-million-year lull in large impacts early in Martian history.

NASA's Cassini, Voyager missions suggest new picture of Sun's interaction with galaxy
New data from three NASA missions show that the heliosphere -- the bubble of the Sun's magnetic influence that surrounds the inner solar system -- may be much more compact and rounded than previously thought.

In experiments on Earth, testing possible building blocks of alien life
Extraterrestrial life, if it exists, could use different amino acid building blocks than living things here on Earth. To better understand what alien life might look like, researchers are studying which amino acids stand up to the types of extreme conditions found on other planets and moons.

Space technologies improve surgeries back on earth
A novel surgical robotic system has been developed that provides tactile feedback and is capable of single-incision and natural orifice (incision-free) robotic surgery. The system minimizes surgical trauma and is safer than currently available robotic systems.

Light rays from a supernova bent by the curvature of space-time around a galaxy
Astronomers have detected for the first time multiple images from a gravitationally lensed Type Ia supernova. The new observations suggest promising new avenues for the study of the accelerated expansion of the universe, gravity and distribution of dark matter in the universe.

Searching for ET: Breakthrough Listen initiative publishes initial results
Breakthrough Listen -- the initiative to find signs of intelligent life in the universe -- has released its 11 events ranked highest for significance as well as summary data analysis results. It is considered unlikely that any of these signals originate from artificial extraterrestrial sources, but the search continues.

Hubble celebrates 27 years with two close friends
This stunning cosmic pairing of the two very different looking spiral galaxies NGC 4302 and NGC 4298 was imaged by the NASA/ESA Hubble Space Telescope. The image brilliantly captures their warm stellar glow and brown, mottled patterns of dust.

Detailed map of potential Mars rover landing site
Mineral deposits in a region on Mars called Northeast Syrtis Major suggest a plethora of once-habitable environments. By mapping those deposits in the region's larger geological context, the research could help set the stage for a possible rover mission.

Living with a star: NASA and partners survey space weather science
Storms from the sun can affect our power grids, railway systems and underground pipelines. Now scientists and engineers from NASA have assessed the state of science surrounding space weather.

Newly discovered exoplanet may be best candidate in search for signs of life
An exoplanet orbiting a red dwarf star 40 light-years from Earth may be the new holder of the title 'best place to look for signs of life beyond the solar system.' Using ESO's HARPS instrument, and other telescopes, astronomers discovered a 'super-Earth' orbiting in the habitable zone around the star LHS 1140. This world is larger and more massive than the Earth and has likely retained most of its atmosphere. This makes it one of the most exciting targets for atmospheric studies.

Milky Way: Hydrogen halo lifts the veil of our galactic home
Astronomers have reported the first detections of diffuse hydrogen wafting about in a vast halo surrounding the Milky Way.

Mission control: Salty diet makes you hungry, not thirsty
We've all heard it: eating salty foods makes you thirstier. But what sounds like good nutritional advice turns out to be not true in the long run. In a study carried out during a simulated mission to Mars, an international group of scientists has found exactly the opposite to be true. 'Cosmonauts' who ate more salt retained more water, weren't as thirsty, and needed more energy.

Landslides on Ceres reflect hidden ice
Massive landslides, similar to those found on Earth, are occurring on the asteroid Ceres. That's according to a new study adding to the growing evidence that Ceres retains a significant amount of water ice.

Supermassive black holes found in two tiny galaxies
Astronomers have found two ultra-compact dwarf galaxies with supermassive black holes, the second and third such galaxies found to harbor the objects. Together, the three examples suggest that black holes lurk at the center of most ultra-compact dwarfs, potentially doubling the number of supermassive black holes known in the universe. The tiny galaxies were likely leftovers of larger galaxies stripped of their outer layers after colliding into other, larger galaxies.

NASA team explores using LISA Pathfinder as 'comet crumb' detector
Scientists hope to take advantage of LISA Pathfinder's record-breaking sensitivity to acceleration to map out the distribution of tiny dust particles shed by asteroids and comets far from Earth.

Hubble sees starbursts in Virgo
Starburst galaxies contain regions where stars are forming at such a breakneck rate that the galaxy is eating up its gas supply faster than it can be replenished.

New insights into 'ocean worlds' in our solar system
Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other "ocean worlds" in our solar system and beyond. Scientists announce that a form of chemical energy that life can feed on appears to exist on Saturn's moon Enceladus, and researchers also report additional evidence of plumes erupting from Jupiter's moon Europa.

Meet 'DeeDee,' a distant, dim member of our solar system
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have revealed extraordinary details about a recently discovered far-flung member of our solar system, the planetary body 2014 UZ224, more informally known as DeeDee.
