In recent times, the European space mission uncovered some of the mysteries behind Milky Way galaxy by spotting star formation and mysterious microwave emissions. NASA is hopeful that the discovery would prove helpful in understanding other mysteries of the galaxy.

Krzysztof M. Gorski from NASA's Jet Propulsion Laboratory said, "The images reveal two exciting aspects of the galaxy in which we live. They show a haze around the center of the galaxy, and cold gas where we never saw it before".

It has been informed that haze appears from area nearby our galaxy. When electrons pass through the haze at high speed, the haze looks like a form of light energy. It has been unveiled that this particular haze, discovered by the astronauts, is different from others as it is brighter and has shorter wavelengths.

It is unclear about the source of the haze. But the scientists are of the view that the supernovae, galactic winds and annihilation of dark-matter particles could be potential sources for haze. However, the source of radiation is still a mystery for the scientists.

An observatory called Planck space observatory has helped a lot in unveiling the mysteries behind the Milky Way galaxy. The observatory was launched in 2009. The observatory was established with the aim of analyzing small fluctuations in the omnipresent cosmic microwave background (CMB).

But in actuality, it has helped in creating a galaxy map. The Planck was put in an orbit, which is 937,000 miles away from the Earth. The Planck has been performing quite well. It was designed to observe minute changes in the temperature in microwave energy released after the Big Bang that created the universe some 14 billion years ago.
