Using an infrared video camera developed by researchers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., surgeons are testing thermal imaging and image processing to see if they can create useful maps of brain tumors.

Astronomers have directly measured the mass of a single star — the first time such a feat has been accomplished for any solitary star other than our own Sun.

The Orange County Astronomers will host AstroImage 2004 on August 27 and 28 at the Curtis Theater in Brea, California.

DIY astronomical images with the expert touch using a software tool created by developed by imaging scientists at the European Space Agency, the European Southern Observatory and NASA...

The National Radio Astronomy Observatory pulls back the curtain on the very center of our galaxy and helps put the right spin on just how fast we're spinning...

NASA’s Chandra X-ray Observatory has uncovered evidence that a single star in a foreground galaxy may have magnified X-rays coming from a rare quadruple quasar. About 11 billion light years from Earth, the Cloverleaf quasar is a single object that appears as four images. The Marshall Center manages the Chandra program.

This odd atmospheric phenomenon, primarily only visible in the skies over North America, has delighted and fascinated observers since the first recorded sighting in 1776...

What would our Milky Way galaxy look like if we could travel outside it and snap a picture?

The first pictures taken by the Cassini spacecraft after it began orbiting Saturn show breathtaking detail of Saturn's rings...

NASA's Hubble Space Telescope captures this iridescent tapestry of star birth in a neighboring galaxy in this panoramic view of glowing gas, dark dust clouds, and young, hot stars.

Amateur Astronomers Group to Build Observatory

Astronomers studying gas clouds in the famous Whirlpool Galaxy have found important clues supporting a theory that seeks to explain how the spectacular spiral arms of galaxies can persist for billions of years.

From the News Archives: On a sultry August night in 1877, U. S. Naval Observatory astronomer Asaph Hall discovered the two moons of Mars, Phobos and Deimos, using the Observatory's 26-inch "Great Equatorial" refracting telescope (by Alvin Clark), then the largest of its kind in the world.

The Cassini spacecraft has beamed back a new, more detailed image of smog-enshrouded Titan. This view represents an improvement in resolution of nearly three times over the previous Cassini image release of Titan.

Astronomers using a global combination of radio telescopes to study a stellar explosion some 30 million light-years from Earth have likely discovered either the youngest black hole or the youngest neutron star known in the Universe. Their discovery also marks the first time that a black hole or neutron star has been found associated with a supernova that has been seen to explode since the invention of the telescope nearly 400 years ago.
