The Hubble Space Telescope has uncovered a mysterious solitary dwarf galaxy - a type that is smaller and messier than its cosmic cousins, lacking the majestic swirl of a spiral or the coherence of an elliptical
Coral reefs have almost always been studied up close, by scientists in the water looking at small portions of larger reefs to gather data and knowledge about the larger ecosystems. But NASA's Jet Propulsion Laboratory is taki
Astronauts aboard the International Space Station on Monday floated inside an experimental inflatable module that will test a less expensive and potentially safer option for housing crews during long stays in space, NASA said
Coronal holes are low-density regions of the Sun's atmosphere, known as the corona. They contain little solar material and have lower temperatures, thus appearing much darker than their surroundings, researchers said.
The mosaic strip - extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto on July 14, 2015 - now includes all of the highest-resolution images taken by the NASA probe.
During summertime in the planet's north, the remaining northern polar cap is all water ice; the southern cap is water ice as well, but remains covered by a relatively thin layer of carbon dioxide ice even in southern summerti
NASA hit a snag while releasing air into an experimental inflatable room at the International Space Station on Thursday and put everything on hold for at least a day. Mission Control ordered astronaut Jeffrey Williams to call
Scientists are able to piece together the history of the Sun by searching for similar stars in our galaxy. By placing these Sun-like stars in order according to their age, the stars appear as a functional timeline of how our
NASA has successfully launched a super pressure balloon on a potentially record-breaking, around-the-world test flight aimed at providing inexpensive access to the near-space environment for science and technology research.
After making a historic Pluto flyby last July and now in deep space, NASA's New Horizons spacecraft has twice observed a first object in Kuiper Belt - a region of the solar system beyond the orbit of Neptune.
In the largest finding of planets to date, NASA has announced the discovery of 1,284 new planets outside our solar system, more than doubling the number of exoplanets found by the Kepler space telescope.
