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.
Radio Telescopes Reveal Youngest Stellar Corpse
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.

Findings from a historic encounter between NASA's Stardust spacecraft and a comet have revealed a much stranger world than previously believed. The comet's rigid surface, dotted with towering pinnacles, plunging craters, steep cliffs, and dozens of jets spewing violently, has surprised scientists...
Young Galaxy in the Very Early Universe
Astronomers using a combination of data sets from the Mayall telescope at Kitt Peak, including the NOAO Deep Wide-Field Survey (see image), have found a galaxy that formed when the Universe was just six percent of its present age, suggesting the "dark ages" of the early universe ended in a patchy, gradual process...
