The observations of the young star system offer a glimpse into the violent process of making rocky planets like Earth.
Moving forward, the agency's schedule includes an initial Space Launch System flight no later than November 2018.
The distance to the “Seven Sisters” of 443 light-years is accurate, the astronomers said, to within 1 percent.
The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.
The "keystone" proton-proton reaction, which created the detected neutrinos, is the first step of a reaction sequence responsible for about 99 percent of the Sun's power.
This star system is extremely volatile and is expected to have at least one supernova explosion in the future.
The new studies show that this distant object looks surprisingly like the comparatively nearby pair of colliding galaxies known as the Antennae.
This is its last major crossing en route to becoming the first probe to make a close encounter with distant Pluto on July 14, 2015.
Using detailed information, five locations have been identified as candidate sites to set down the Philae lander in November.
The production of the new map was inspired by anticipation of NASA's New Horizons encounter with Pluto.
Astronomers have discovered a low-mass star that exhibits the peculiar chemical abundance ratios associated with the process of creating new atomic nuclei in a first-generation massive star.
The European Southern Observatory captured two dramatic star formation regions in the southern Milky Way — NGC 3603 and NGC 3576.
A team of astronomers obtained the most sensitive image of this galaxy below 1 gigahertz.
The survey’s five-year mission is to unravel the fundamental mystery of dark energy and its impact on our universe.
Astronomers have succeed in accurately measuring — and thus confirming the existence of — an intermediate-mass black hole.
The comet’s head exhibits parallel linear features that resemble cliffs, its neck displays scattered boulders, and its body exhibits a multivariable terrain with peaks and valleys.
The seven particles were perhaps created in a supernova explosion millions of years ago.
Scientists ruled out that the explosion was caused by a white dwarf continuously pulling material from a companion star.
IC 4499’s mass lies somewhere between low-mass globulars, which show a single generation build-up, and the more complex and massive globulars, which can contain more than one generation of stars.
The shadow cast by the rock in midafternoon sunlight reveals it is about 20 feet (6 meters) tall and about 11.5 feet (3.5 meters) wide.
