Iz udaljene galaksije dopiru tajanstveni signali [alias] => astronomi-detektirali-vanzemaljski-svemirski-brod-iz-udaljene-galaksije-dopiru-tajanstveni-signali [catid] => 423 [published] => 1 [introtext] => [fulltext] =>

Astronomi su otkrili detalje tajanstvenih signala koji izviru iz daleke galaksije, koje je pokupio teleskop u Kanadi, prenosi britanski Daily Mirror.

Točna priroda i podrijetlo eksplozija radio valova nije poznato.

Među 13 brzih radijskih rafala, poznatih kao FRB, bio je vrlo neobičan ponavljajući signal, koji je dolazio iz istog izvora udaljenog oko 1,5 milijardi svjetlosnih godina.

Takav je događaj zabilježen samo jednom, drugim teleskopom.

- Spoznaja da postoji još jedan, sugerira da bi vani moglo biti više - rekla je Ingrid Stairs, astrofizičarka sa Sveučilišta British Columbia (UBC).

- S više ponavljanja i više izvora dostupnih za proučavanje, možda ćemo moći razumjeti ove kozmičke zagonetke, odakle su i što ih uzrokuje - kazala je.

Opservatorij CHIME, koji se nalazi u dolini Okanagan u Britanskoj Kolumbiji, sastoji se od četiri polucilindrične antene duge 100 metara, koje svakodnevno skeniraju cijelo sjeverno nebo.

Teleskop je pokrenut tek prošle godine, detektirajući 13 radijskih rafala gotovo odmah, uključujući repetitor.

Istraživanje je objavljeno u časopisu 'Nature'.

- Otkrili smo drugi repetitor i njegova svojstva su vrlo slična prvom - rekao je Shriharsh Tendulkar sa Sveučilišta McGill u Kanadi.

- Ovo nam govori više o svojstvima repetitora kao populacije - dodao je.

FRB su kratki, svijetli bljeskovi radio valova.

Dosad su znanstvenici otkrili oko 60 pojedinačnih brzih radijskih rafala i dva koja se ponavljaju. Vjeruju da bi na nebu moglo biti čak tisuću FRB-ova svaki dan.

Postoje brojne teorije o tome što bi ih moglo uzrokovati.

Oni uključuju neutronsku zvijezdu s vrlo jakim magnetskim poljem koje se vrti vrlo brzo, dvije neutronske zvijezde koje se spajaju i, među manjim brojem promatrača, neki oblik vanzemaljskog svemirskog broda, piše Daily Mirror.

Astronomi su otkrili detalje tajanstvenih signala koji izviru iz daleke galaksije, koje je pokupio teleskop u Kanadi, prenosi britanski Daily Mirror.

Točna priroda i podrijetlo eksplozija radio valova nije poznato.

Među 13 brzih radijskih rafala, poznatih kao FRB, bio je vrlo neobičan ponavljajući signal, koji je dolazio iz istog izvora udaljenog oko 1,5 milijardi svjetlosnih godina.

Takav je događaj zabilježen samo jednom, drugim teleskopom.

- Spoznaja da postoji još jedan, sugerira da bi vani moglo biti više - rekla je Ingrid Stairs, astrofizičarka sa Sveučilišta British Columbia (UBC).

- S više ponavljanja i više izvora dostupnih za proučavanje, možda ćemo moći razumjeti ove kozmičke zagonetke, odakle su i što ih uzrokuje - kazala je.

Opservatorij CHIME, koji se nalazi u dolini Okanagan u Britanskoj Kolumbiji, sastoji se od četiri polucilindrične antene duge 100 metara, koje svakodnevno skeniraju cijelo sjeverno nebo.

Teleskop je pokrenut tek prošle godine, detektirajući 13 radijskih rafala gotovo odmah, uključujući repetitor.

Istraživanje je objavljeno u časopisu 'Nature'.

- Otkrili smo drugi repetitor i njegova svojstva su vrlo slična prvom - rekao je Shriharsh Tendulkar sa Sveučilišta McGill u Kanadi.

- Ovo nam govori više o svojstvima repetitora kao populacije - dodao je.

FRB su kratki, svijetli bljeskovi radio valova.

Dosad su znanstvenici otkrili oko 60 pojedinačnih brzih radijskih rafala i dva koja se ponavljaju. Vjeruju da bi na nebu moglo biti čak tisuću FRB-ova svaki dan.

Postoje brojne teorije o tome što bi ih moglo uzrokovati.

Oni uključuju neutronsku zvijezdu s vrlo jakim magnetskim poljem koje se vrti vrlo brzo, dvije neutronske zvijezde koje se spajaju i, među manjim brojem promatrača, neki oblik vanzemaljskog svemirskog broda, piše Daily Mirror.

Astronomi detektirali vanzemaljski svemirski brod? Iz udaljene galaksije dopiru tajanstveni signali

Astronomi su otkrili detalje tajanstvenih signala koji izviru iz daleke galaksije, koje je pokupio teleskop u Kanadi, prenosi britanski Daily Mirror.

Točna priroda i podrijetlo eksplozija radio valova nije poznato.

Među 13 brzih radijskih rafala, poznatih kao FRB, bio je vrlo neobičan ponavljajući signal, koji je dolazio iz istog izvora udaljenog oko 1,5 milijardi svjetlosnih godina.

Takav je događaj zabilježen samo jednom, drugim teleskopom.

- Spoznaja da postoji još jedan, sugerira da bi vani moglo biti više - rekla je Ingrid Stairs, astrofizičarka sa Sveučilišta British Columbia (UBC).

- S više ponavljanja i više izvora dostupnih za proučavanje, možda ćemo moći razumjeti ove kozmičke zagonetke, odakle su i što ih uzrokuje - kazala je.
