COS­MIC EX­PLO­SIONS FLING GOLD ACROSS UNI­VERSE

The Gulf Today - Panorama - - HAVE YOU HEARD? -

Nasa sci­en­tists have spot­ted what they think are im­mense ex­plo­sions caused by neu­tron stars col­lid­ing into each other in dis­tant space.

When that cat­a­strophic event hap­pened, it sent an in­tense jet of of high-en­ergy par­ti­cles through space that made their way past the sci­en­tists who spot­ted them us­ing Nasa’s ar­ray of space tele­scopes.

Look­ing at the data from those tele­scopes could shed more light on some of the most spec­tac­u­lar and in­tense col­li­sions found in space. And it could sug­gest that sig­nif­i­cant events of the kind de­scribed by sci­en­tists are rel­a­tively com­mon.

The re­searchers think the ex­plo­sion could be a “kilo­nova.” That is a bright flash of ra­dioac­tive that flings out huge quan­ti­ties of im­por­tant el­e­ments like sil­ver, gold, plat­inum and ura­nium.

The an­nounce­ment comes af­ter sci­en­tists an­nounced last Oc­to­ber that they had seen the first ex­plo­sion of this kind.

At the time, that dis­cov­ery was hailed as a “new chap­ter in as­tro­physics” and an un­ex­pected dis­cov­ery.

Now, sci­en­tists have found what they think might be a re­lated event, known as GRB150101B — and one that sug­gests such spec­tac­u­lar ex­plo­sions could be far more com­mon than we had re­alised.
