Forbes: radio signal from distant galaxy detected

Αστρονόμοι που χρησιμοποιούσαν ραδιοτηλεσκόπιο στην Ινδία κατέγραψαν το πιο μακρινό ραδιοσήμα από έναν γαλαξία, τροφοδοτώντας τις ελπίδες ότι τα μυστικά του πρώιμου σύμπαντος μπορούν να αποκαλυφθούν χρησιμοποιώντας την υπάρχουσα τεχνολογία τηλεσκοπίων σύμφωνα με δημοσίευμα του Forbes.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 astronomy, underlines Forbes.

The technique they used

They used a technique called gravitational lensing, a ripple in space-time that allows background objects to be greatly magnified relative to foreground objects.

Radio signals get weaker the farther a galaxy is from Earth, making it difficult to detect with today's radio telescopes, but a new study published this week in the Monthly Notices of the Royal Astronomical Society gives hope that detecting galaxies at much greater distances from Earth may now be in close proximity.

"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." The Best Technology Site in Greece

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