Forbes: radio signal from distant galaxy detected

Astronomers using a radio telescope in India have recorded the most distant radio signal from a galaxy, fueling hopes that secrets of the early universe can be revealed using existing telescope technology, Forbes reported.andromeda galaxy

The signal came from a galaxy called SDSSJ0826+5630 located 8,8 billion light-years away. This essentially means that it exists closer to the Big Bang than any other galaxy previously detected using radio, underlines Forbes.

H that they used

They used a technique called gravitational , a ripple in space-time that allows background objects to become quite large relative to foreground objects.

Radio signals get weaker the further away one is από τη Γη, γεγονός που καθιστά δύσκολο την ανίχνευση από τα σημερινά ραδιοτηλεσκόπια, αλλά μια νέα μελέτη που δημοσιεύτηκε αυτή την εβδ in the Monthly Notices of the Royal Astronomical Society gives hope that the detection of galaxies at much greater distances from Earth may now be within reach.

"A galaxy emits different kinds of radio signals," said Arnab Chakraborty, a postdoctoral researcher studying cosmology in the Department of Physics at McGill University in Montreal, Canada. "Until now, it has only been possible to pick up this particular signal from a nearby galaxy, limiting our knowledge to those galaxies closest to Earth."

Although the press releases will be from very select to rarely, I said to go ... because sometimes the authors are hiding.
