The oldest stars in the halo have ages of 12 to 13 billion years, so we estimate that the formation of the Galaxy began about that long ago. (See the chapter on The Big Bang for other evidence that galaxies in general began forming a little more than 13 billion years ago.) Then, ...
NASA's Research on the Blue Dunes NASA has been at the forefront of studying the blue dunes on Mars. Through a series of missions, including the Mars Reconnaissance Orbiter (MRO), NASA has been able to capture high - resolution images of these dunes. The MRO is equipped with advanced came...
drawing with it unconsolidated fines from beneath the ice in the form of a plume, and depositing the material as relatively low albedo fans and spots. A combined effort by Piqueux3who identified and described spiders, and Kieffer, who developed a formation hypothesis, linked araneiform formation...
Nature's series of review articles on astronomy, marking the International Year of Astronomy 2009, continues with a look at the 'final frontier' in observational astronomy: the formation of the first stars, galaxies and massive black holes. At present th
NASA is finally headed back to Venus. On June 2, 2021, NASA Administrator Bill Nelson announced that the agency had selected two winners of its latest Discovery class spacecraft mission competition, ...more Mars rover to move south after testing ...
NASA formation NASA was officially formed through the National Aeronautics and Space Act of 1958 to in part, pursue "activities in space [that] should be devoted to peaceful purposes for the benefit of all mankind." (Today, NASA recognizes a diverse workforce and uses terms such as "humans"...
from the formation of the solar system about 4.6 billion years ago. Most of the time, these ancient rocks pose no danger to Earth, includingDimorphos, the one NASA just used for target practice. But at least three have caused mass extinctions, the most infamous of which wiped out the...
Jupiter was probably the first planet to form in thesolar system, made up of gasses left over from theformation of the sun. If the planet had been about 80 times more massive during its development, it would have actuallybecome a star in its own right, according to NASA. ...
Millions of space rocks orbit the sun. They're the rocky rubble left over from the formation of the solar system about 4.6 billion years ago. Most of that ancient detritus is too far away to pose a threat to this planet. The majority are in the main asteroid belt between Mars and Jupit...
NASA’s InSight mission is the first lander to deploy a seismometer on a planetary body since more than 40 years. With a year of seismic data from Mars, new discoveries on Mars’ tectonics and interior structure are just emerging.
