Space scientists reveal brightest gamma explosion ever

By Dan MartinBBC News

Scientists have revealed how Nasa satellites detected the brightest ever Gamma Ray explosion In Space .

The gamma-ray burst (Grb ) occurred Two billion lightyears from Earth and illuminated much of The Galaxy .

Images of the rare and powerful cosmic phenomenon show a halo and " bullseye" Like shapes.

Experts, including academics from the University of Leicester, say the Grb was ten times brighter than any other previously detected.

They have released detailed analysis of the powerful explosion, which happened on 9 October, 2022.

The blast was officially named Grb 221009A But has been nicknamed The Boat - Brightest Of All Time - by those working on a mission Nasa calls Swift.

X-ray astronomer Dr Phil Evans, who leads the University of Leicester's involvement in Swift, said: " We were really lucky to see something Like this. We estimate That events this bright occur roughly once every thousand years.

" By studying the evolution of this astonishingly bright Grb in great detail, we can learn a lot about The Physics of a Blast Wave .

" Just Like slow-mo cameras reveal details about movement, breaking our data into small Time Pieces allows us to see how the Grb changes and learn more. "

The Swift team said its Neil Gehrels Swift Observatory, a satellite telescope designed to study GRBs from space, was initially unable to observe the burst because The Earth was obstructing its view.

However 55 minutes later, when the satellite's orbit allowed it to have a clear view of the Grb , its systems successfully detected it and created images of it.

What are Gamma Ray bursts?

Dr Andy Beadmore, who is also part of the Swift team at the University of Leicester, said: " These patterns are not just beautiful But are also useful scientifically.

" We're seeing a significant amount of dust in our Galaxy being lit up by the intense burst of light from the Grb - Two billion lightyears Away - Like a torch Shining Through a cloud.

" This lets us study its nature and composition, which was found to extend to large distances from The Sun .

" The brightness of this Grb means That we can collect much better data than normal, and so move beyond simple models of the Grb physics That we normally use - They just can't explain these data. "

'Beautiful halo'

Dr Evans added: " Even after 18 years of operation, Swift can still surprise us with something unexpected, awesome, and scientifically powerful, and it can still challenge us.

" Those dust rings may look pretty But They gave us some headaches, They really complicated the Data Analysis .

" Even with those complications, though, this event gives us an opportunity to study a Grb in unprecedented detail.

" Then there's The Beautiful dust halo That Andy discovered.

" This is caused by massive clouds of dust in our Galaxy But it's The Light from the Grb , around Two billion lightyears Away That 's actually revealed those clouds to us.

" Now, we can measure Their Distance and their composition using this Grb 'backlight'.

" This discovery is a testament to The Power of careful observation and the potential of serendipitous discoveries.

" I'm thrilled That our team was able to contribute to our understanding of The Universe in such a meaningful way. "
