Atmosphere detected on celestial body in solar system's far reaches

Astronomers have identified another object from this realm, with a diameter of roughly 310 miles (500 km), that has an atmosphere - albeit a thin one.

Scientists discover that galactic collisions cause quasars - study

Contrary to previous beliefs that the quasars are formed at the peak of galactic collision, researchers found that they are actually formed during the initial stages of collision.

 This artist’s impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked.

Detailed dark matter map provides further support for Einstein's theory of general relativity

Astronomers have created the most detailed map of dark matter distribution.

 One of the Unit Telescopes of ESO's Very Large Telescope (VLT) is producing artificial stars in the skies above the Atacama Desert, above the Milky Way.

What are mysterious cosmic objects shining brighter than the sun?

They produce way more energy than the sun and appear to break a physical boundary called the Eddington limit - now scientist found a possible explanation.

 Swift X-ray observations of galaxy NGC 5408 indicate its ultraluminous X-ray source undergoes periodic changes every 115.5 days. This cycle, astronomers suspect, is linked to the orbit of a donor star around a middleweight black hole, as shown in this artist's view.

Get your telescopes ready: Five planets to align on Monday

Scientists recommend finding a clear view of the western horizon and using binoculars to view the planets.

 This artist's impression shows two Earth-sized worlds passing in front of their parent red dwarf star, which is much smaller and cooler than our Sun. The star and its orbiting planets TRAPPIST-1b and TRAPPIST-1c reside 40 light-years away.
