Milky Way has four spiral arms: Study

Researchers have said that a 12-year-old study of massive stars has reaffirmed that Milky Way has four spiral arms.

Early universe was less dusty than believed

Dust may be more rare - even 100 times less - than expected in galaxies of the early Universe, a new study has found.

`Young` Milky Way star shone 100 times brighter while growing up

Researchers have shown that a young, newly formed star in the Milky Way - formed within the past 100,000 years- underwent such an explosive growth, that it was initially about 100 times brighter than it is now.

Stars move in peanut-shell shaped orbits at center of galaxy

A new study suggests that the stars probably move in peanut-shell or figure of eight-shaped orbits instead.

Evidence of jet in Milky Way`s supermassive black hole found

Astronomers, who have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles, have finally found it.

The Herschel Space Observatory has revealed that the star forming sites across the Milky Way are riddled with filaments.

One in five Milky Way stars may have Earth-like planets: Study

One out of every five sun-like stars in the Milky Way galaxy has a planet about the size of Earth that is properly positioned for water, a key ingredient for life, a study released on Monday showed.

Magnetic `force field` to shield giant gas cloud during crash with Milky Way Galaxy

Astronomers have found that doom may be averted for the Smith Cloud, a gigantic streamer of hydrogen gas that is on a collision course with the Milky Way Galaxy, because of a magnetic field deep in the cloud`s interior may protect it during its plunge.

New methods could make Milky Way supernova visible from Earth in next 50 yrs

Astronomers have deduced that sometime during the next 50 years, a supernova occurring in Milky Way galaxy is going to be visible from Earth.

Milky Way `swallows gas clouds wrapped in magnetic field` to give birth to stars

Milky Way may have been swallowing "pills" - clouds of gas with a magnetic wrapper - to keep creating stars for the past eight billion years.

Violent past of Milky Way`s giant black hole revealed

NASA`s Chandra X-ray Observatory has helped find evidence that the normally dim region very close to the supermassive black hole at the center of the Milky Way Galaxy, flared up with at least two luminous outbursts in the past few hundred years.

Best 3D map of Milky Way`s centre created

Astronomers have created the best three-dimensional map yet of the central parts of the Milky Way - and found that the inner regions take on a peanut-like, or X-shaped, appearance.

Astronomers using NASA`s Chandra X-ray Observatory have made a major breakthrough in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays.

200 bn free-floating starless planets roam Milky Way

Scientists have found that planets with no parent star can be born freely, outside of an existing solar system - and there are 200 billion of them in our galaxy.
