PARIS ‘Strong sig­nal’ stirs in­ter­est in hunt for alien life

The Myanmar Times - - World -

A “STRONG sig­nal” de­tected by a ra­dio tele­scope in Rus­sia that is scan­ning the heav­ens for signs of ex­trater­res­trial life has stirred in­ter­est among the sci­en­tific com­mu­nity.

“No one is claim­ing that this is the work of an ex­trater­res­trial civ­i­liza­tion, but it is cer­tainly worth fur­ther study,” said Paul Gil­ster, au­thor of the Cen­tauri Dreams web­site which cov­ers peer­re­viewed re­search on deep space ex­plo­ration.

The sig­nal is from the di­rec­tion of a HD164595, a star about 95 light years from Earth. The star is known to have at least one planet, and may have more.

The ob­ser­va­tion is be­ing made pub­lic now, but was de­tected last year by the RATAN-600 ra­dio tele­scope in Ze­lenchuk­skaya, Rus­sia.

Ex­perts say it is far too early to know what the sig­nal means or where, pre­cisely, it came from.

“But the sig­nal is provoca­tive enough that re­searchers are call­ing for per­ma­nent mon­i­tor­ing of this tar­get,” wrote Mr Gil­ster.

The dis­cov­ery is ex­pected to fea­ture in talks at the 67th In­ter­na­tional Astro­nau­ti­cal Congress in Guadala­jara, Mex­ico, on Septem­ber 27.

“Based on the sig­nal’s strength, the re­searchers say that if it came from an iso­tropic beacon, it would be of a power pos­si­ble only for a Kar­da­shev Type II civ­i­liza­tion,” Mr Gil­ster wrote, re­fer­ring to a scale-sys­tem that in­di­cates a civ­i­liza­tion far more ad­vanced than our own.

Mr Gil­ster, who broke the story on Au­gust 27, said he had seen a pre­sen­ta­tion on the mat­ter from Italian as­tronomer Clau­dio Mac­cone. –
