Roughly 500 million light-years away, near the constellation Delphinus, two galaxies are colliding. Known as merging galaxy IIZw096, the luminous phenomenon is obscured by cosmic dust, but ...

Among the most abundant sources of light on Earth is life itself. ... In this case, the fish doesn’t make the light itself. Instead, luminous bacteria, which live within the lure, ...

Gas is being expelled from the centre of two ultra-luminous x-ray sources in nearby galaxies. INTERNATIONAL ... Ultra-luminous x-ray sources seen spewing out gas at a quarter of the speed of light.

An AGN is powered by a supermassive black hole actively feeding on gas in the center of a galaxy, and it is usually an extremely bright source of light (quasars being the most luminous AGNs in visible ...

“We think these ‘ultra-luminous X-ray sources’ are somewhat special binary systems, sucking up gas at a much higher rate than an ordinary X-ray binary,” said Ciro Pinto, a research ...

A light source’s luminous intensity is different from its luminous flux. The latter measures the power output - expressed in lumens (lm) - according to the Vλ of a light source in every direction.

Ultra-luminous X-ray sources (ULXs, for short) ... The finding confirms that these light emitters are indeed as bright as they seem and that they break the Eddington limit.

In the latest discovery, H.E.S.S. found three extremely luminous gamma-ray sources in the Large Magellanic Cloud (LMC), a satellite dwarf galaxy of the Milky Way.

Using a telescope in Chile, astronomers have captured a high-speed collision between two galaxies located more than 11 billion light-years away, getting a rare direct glimpse into how the universe ...
