Image: Black hole outburst in spiral galaxy M83

( -- NASA's Chandra X-ray Observatory has discovered an extraordinary outburst by a black hole in the spiral galaxy M83 (Messier 83), located about 15 million light years from Earth.

'Extremely little' telescope discovers pair of odd planets

Even small telescopes can make big discoveries. Though the KELT North telescope in southern Arizona carries a lens no more powerful than a high-end digital camera, it's just revealed the existence of two very unusual faraway ...

Kepler Telescope star data creates musical melody

Why stop at the dark side of the moon to make music when you can look thousands of light years into space? That's what a team of Georgia Tech researchers have done, using data from two stars in our galaxy to create sounds ...

One supernova type, two different sources

The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They're bright enough to see across large distances, and similar enough ...

NASA's Chandra sees remarkable outburst from old black hole

An extraordinary outburst produced by a black hole in a nearby galaxy has provided direct evidence for a population of old, volatile stellar black holes. The discovery, made by astronomers using NASA's Chandra X-ray Observatory, ...

Hubble's panoramic view of a turbulent star-making region

( -- Several million stars are vying for attention in this NASA/ESA Hubble Space Telescope image of a raucous stellar breeding ground in 30 Doradus, located in the heart of the Tarantula nebula.

Swift narrows down origin of important supernova class

( -- Studies using X-ray and ultraviolet observations from NASA's Swift satellite provide new insights into the elusive origins of an important class of exploding star called Type Ia supernovae.

Black hole jets

( -- Black holes are irresistible sinks for matter and energy. They are so dense that not even light can escape from their gravitational clutches. Massive black holes (equal to millions or even billions of solar ...
