For rocket engineer Edward Miyashiro, inspiration came from the space race and a curious mind — but do U.S. students have the inspiration to eventually take his place?

The newfound object, called 2012 VP113, joins the dwarf planet Sedna as a resident of a far-flung region called the "inner Oort Cloud." Further, 2012 VP113 and Sedna may have been pulled into their odd orbits by a big, undiscovered planet.

Volunteers with no astronomy experience can pick out craters on the moon as accurately as a researcher with five to 50 years' experience, a new study reports. The finding could give a further boost to the use of citizen scientists in research projects.

A new telescope tool for peering into the cosmos and creating three-dimensional views of the universe has passed its first major test at a European observatory in Chile's high desert.
21 March 2014, 12:08 PM ET caught up with John Kovac recently to talk about his team's detection of gravitational waves, the find's implications and what the discovery means to him and his team on a personal level.

NASA is distancing itself from a new study that investigates how resource exploitation andincome inequality could lead to the collapse of civilization. The paper just used research tools developed for other NASA activities, agency officials say.

The confirmation of cosmic inflation gives researchers a new window onto a realm of extreme physics, potentially aiding their quest to devise a theoretical framework that can explain all aspects of the universe.

This space wallpaper shows an unusually bright gamma-ray burst, which produced a jet that emerged at nearly the speed of light. Gamma-ray bursts are the most powerful type of explosions in the universe and typically mark the destruction of a massive star.

Spring has officially sprung in the Northern Hemisphere and NASA is celebrating with a dazzling new view of the Earth from space today (March 20).

The new infrared mosaic from Hubble shows knotty curls of dust and gas in the Monkey Head Nebula, a star-forming region that lies about 6,400 light-years away from Earth and is also known as NGC 2174 and Sharpless Sh2-252.
19 March 2014, 06:17 PM ET
The new mosaic — which was captured by NASA's Lunar Reconnaissance Orbiter — resolves features as small as 6.5 feet, providing information that could be used for landing-site scouting or to answer various questions about the lunar surface.

From space tourism to mining asteroids, space exploration has entered the commercial era. Tonight, aerospace industry leaders and space historians will gather at the American Museum of Natural History for a live debate about "selling space."

As galaxies speed through gigantic cauldrons, they occasionally jumble the gas and forge it into lop-sided shapes. An example is revealed in this space wallpaper, which is a composite image of the galaxy group NGC 5044.

The first direct evidence of cosmic inflation — a rapid period of expansion that occurred a fraction of a second after the Big Bang — could also help support the idea that this universe exists in a multiverse, scientists suggest.
18 March 2014, 09:25 AM ET
The find suggests that space-time really did expand at many times the speed of light in the first few tiny fractions of a second after the Big Bang, as predicted by the theory of cosmic inflation, researchers say.

The Nobel laureate talks about the apparent detection of gravitational wave signatures in the cosmic microwave background radiation, as well as what it was like to spot the CMB in 1964, putting the Big Bang theory on solid ground.

The Dasht-e Lut salt desert in southeast Iran is captured in this stunning space wallpaper. The desert is often called the ‘hottest place on Earth’ as satellites measured record surface temperatures there for several years.

Astronomers have found the first direct evidence of cosmic inflation, the theorized dramatic expansion of the universe that put the "bang" in the Big Bang 13.8 billion years ago. The find also confirms the existence of gravitational waves.
17 March 2014, 12:09 PM ET
Evidence that the universe rapidly expanded in its first few nanoseconds has been found by an instrument in Antarctica: Gravitational waves, which have long eluded astronomers, were spotted, supporting this cosmic inflation model.
