The formation and growth of galaxies in the early universe is a key research topic for future giant telescopes like the Giant Magellan Telescope and space missions like the James Webb Spa...

When a star like our Sun gets to be old, in another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining it...

The Arches cluster is a massive star cluster located in the Galactic Center region of our galaxy, about one hundred light-years from the galaxy's supermassive blackhole, SgrA*, and about ...

A Public Collection for Science With a large number of scientific journals ranging from general science to small subfields, it’s impossible for researchers or libraries to subscribe...

Our Milky Way galaxy has probably collided or otherwise interacted with other galaxies during its lifetime; such interactions are common cosmic occurrences. Astronomers can deduce the his...

Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three billion years after the big bang. Their ...

Mark Reid, a Senior Radio Astronomer at the Smithsonian Astronomical Observatory, which is a part of the Center for Astrophysics | Harvard Smithsonian, was elected to the membership of th...

Low mass stellar objects include both low-mass stars (less than about one half of the Sun's mass) and substellar brown dwarfs which, having less than about eighty Jupiter-masses, are unab...

Washington, DC The Smithsonian today made available a new online interactive that allows users to explore a three-dimensional (3D) visualization of the remnants of a supernova, or explod...

X-ray observations have found copious amounts of very hot gas in galaxy clusters, and in the central regions more than was expected. While supernovae and shock excitation will heat the ga...
