Very Large Telescope’s Observations Show Dusty Cloud G2 is Very Compact

Fresh data from the European Southern Observatory's (ESO) Very Large Telescope (VLT) showed that the dusty gas cloud G2 did not appear to be significantly stretched and is very compact.

There are higher possibilities that the object could be a young star with a massive core that is still accreting material. And the black hole itself has not shown any increase in activity so far.

A supermassive black hole with a mass 4 million times that of the Sun lies at the heart of the Milky Way Galaxy, said scientists.

This black hole is orbited by small group of bright stars and dusty cloud known as G2, which has been tracked during its fall towards the black hole over the last few years, they added.

The best observations so far of the dusty gas cloud showed that the G2 has made its closest approach to the supermassive black hole in May 2014.

The great tidal forces in this region of strong gravity were expected to tear the cloud apart and disperse it along its orbit.

Some of this material would feed the black hole and lead to sudden flaring and other evidence of the monster enjoying a rare meal.

Researchers in order to study these unique events, observed the galactic center very carefully for past few years using large telescopes around the world.

It was found that a team led by Andreas Eckart from the University of Cologne in Germany has observed the region using ESO's VLT over many years, including new observations during the critical period from February to September 2014, just before and after the peribothron event in May 2014.

The images of infrared light coming from glowing hydrogen show that the cloud was compact both before and after its closest approach as it swung around the black hole.
