The Milky Way galaxy, home to our planet Earth and the solar system harbours a lot of secrets about the universe that we may never know. 

Even then, scientists continue to confront the question of our existence including the origins of our solar system. Now, scientists have traced strange signals coming from the centre of the Milky Way.

Why the signals are strange

The Earth is nowhere close to this region and scientists are perplexed owing to the repetitive nature of this radio signal. In a new study set to be published in The Astrophysical Journal soon, scientists claim that these signals represent energy signatures unlike anything ever recorded. 

The source of this energy is extremely bipolar, for it appears strongly on the radio spectrum strongly for weeks and then completely disappears within a day. Its behaviour isn't in sync with known profiles of any space object.

Why is this big? It could be a new space object unknown to mankind sending these signals. The scientists refer to it as potentially a "a new class of objects" that are being discovered through radio imaging.

Officially named "ASKAP J173608.2−321635", the source was detected with help from the Australian Square Kilometre Array Pathfinder (ASKAP) telescope, which is situated in the remote regions of Australia. 

Between April 2019 and August 2020, the ASKAP survey recorded the strange signal 13 times. Every time, the signal would appear only for a few weeks before disappearing completely.

What's sending the signal from the centre of Milky Way? 

We really don't know. But scientists have a few guesses. For instance, the source of this radio signal could be a mysterious space object classified as galactic center radio transient (GCRT), which is a radio source which brightens and then dims out in the center of Milky Way.
