The full findings of the study were published in the journal Nature Astronomy. ESO officials said in the statement that this initial amount of time regarding star formation in our galaxy was followed by six billion years during which "very few" stars were formed.

In contrast, one or two stars are formed now in the Milky Way every year, the research team explains.

Michael Brown, an observational astronomer at Monash University in Melbourne, Australia who is not affiliated with the said research explained that it has been a long-running debate in astronomy whether star populations are built up gradually over billions of years or in a sequence of shorter bursts.

'Our unprecedented gaze of a gargantuan section of the Galactic centre has given us detailed insights into the formation course of of stars on this converse of the Milky Ability, ' acknowledged creator Rainer Schödel of the Institute of Astrophysics of Andalusia in Spain.

Scientists have discovered a spectacular explosion of stars in our early galaxy, a burst of formation that resulted in 100,000 supernova explosions. Thanks to the VLT observations, the researchers have found evidence for a dramatic event in the life of our Galaxy: a burst of star formation so intense that it resulted in over a hundred thousand supernova explosions.

But then, like Lazarus himself, the galaxy finally sprung back to life about one billion years ago, furiously churning out stars like the glory days of yore - with a combined mass of up to 42 million times that of our sun.

The European Southern observatory (ESO) constructed the strongest telescope ever made within the Atacama Barren converse of northern Chile.

"The conditions in the studied region during this burst of activity must have resembled those in "starburst" galaxies, which form stars at rates of more than 100 solar masses per year", said Francisco Nogueras-Lara of the Max Planck Institute for Astronomy in Germany.

It's known as the Very Giant Telescope (VLT) and is broadly considered one of the superior optical devices ever made.

The large telescopes are called Antu, Kueyen, Melipal and Yepun.

This research was possible because of observations of the Galactic central region carried out with ESO's HAWK-I instrument on the VLT within the Chilean Atacama Desert.

The major of the Unit Telescopes, "Antu", went into routine scientific operations on April 1, 1999.

It has been involved in spotting the first image of an extrasolar planet as well as tracking individual stars moving around the supermassive black hole at the centre of the Milky Way.
