Milky Way may not be the shape we thought - study

Over the years, astronomers have classified galaxies into three main shapes: elliptical, irregular and spiral.

 This illustration shows a stage in the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. In this image, representing Earth's night sky in 3.75 billion years, Andromeda (left) fills the field of view

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.

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.
