A dramatic new Chandra image of the nearby galaxy Centaurus A provides one of the best views to date of the effects of an active supermassive black hole.

In the distant, young universe, quasars shine with a brilliance unmatched by anything in the local cosmos. Although they appear starlike in optical telescopes, quasars are actually the bright centers of galaxies located billions of light-years from Earth.

Shoes may not come in every color, but space objects do. All objects in space, everything from dust to distant galaxies, give off a rainbow of light - including light our eyes can't see. That's where NASA's Great Observatories come in. Together, they help astronomers see all the shades of the cosmos.

A team of scientists, including researchers in the University of Southampton’s School of Physics and Astronomy, has shown that black holes are not the only known objects in the universe to produce infrared light from beams of particles being shot into space at nearly the speed of light.

By Deborah Zabarenko WASHINGTON (Reuters) - Black holes turn out to be "green." These monstrous matter-sucking drains in space are the most fuel-efficient engines in the universe, researchers said on Monday.

Like traffic on a freeway, plasma spewing from the poles of newborn stars moves in clumps that travel at different speeds. When fast-moving particles run into slower material on these cosmic freeways, the resulting "traffic jams" create massive shock waves that travel trillions of miles.

Applied physicists at the California Institute of Technology have devised a plasma experiment that shows how huge long, thin jets of material shoot out from exotic astrophysical objects such as young stars, black holes, and galactic nuclei.

Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...

bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
