“#Mystery signal coming from inside the Milky Way is repeating itself<\/strong>”
\n<\/p>\n

\n The first burst of cosmic radio waves to be detected within our galaxy is repeating, according to scientists, shedding new light on one of the great mysteries of the universe.<\/p>\n

The ultra-bright flashes of energy, more powerful than those emitted by the Sun, come from a young star about 30,000 light-years from Earth.<\/p>\n

Multiple telescopes detected a cosmic signal coming from the star in April and in a new paper scientists reveal that it has repeated twice in the months since.<\/p>\n

Known as fast radio bursts (FRB), these high-intensity emissions usually last only for a fraction of a second.<\/p>\n

FRBs were first detected in 2007 but almost all that have been detected so far were too far away to clearly make out where they came from.<\/p>\n

More than 100 have been discovered to date, but only a handful have repeated and fewer still in a predictable pattern.<\/p>\n

This makes them notoriously difficult to study, meaning their origins have eluded scientists for over a decade.<\/p>\n

Researchers say their recently-discovered radio flares are the closest FRBs identified to date and come from an object known as a magnetar.<\/p>\n

Magnetars are a type of neutron star with a hugely powerful magnetic field \u2013 only a handful of them are thought to be present in the Milky Way.<\/p>\n

Physicists have previously speculated that magnetars might produce FRBs but there was no evidence to prove that was the case.<\/p>\n

It means the signals don\u2019t come from alien civilizations, a theory touted by some UFO hunters but widely dismissed by the scientific community.<\/p>\n

The new research, published in the journal Nature Astronomy<\/a> on Monday, builds upon a ground-breaking paper released earlier this month about the FRB \u2013 known as FRB 200428.<\/p>\n

That study confirmed the signal from the magneton star SGR 1935+2154 was a fast radio burst.<\/p>\n

This week\u2019s research reveals that two new bursts of varying intensity have been emitted from the star since April \u2013 meaning the burst repeats.<\/p>\n

Using four European radio telescopes, researchers led by Chalmers University in Sweden, monitored the burst\u2019s source every night for four weeks following its discovery.<\/p>\n

On 24 May 2020, the Westerbork Radio Telescope in the Netherlands caught two millisecond-long radio bursts from the magnetar, 1.4 seconds apart.<\/p>\n

\u201cWe clearly saw two bursts, extremely close in time,\u201d said team member Dr. Kenzie Nimmo, of the University of Amsterdam.<\/p>\n

\u201cLike the flash seen from the same source on April 28, this looked just like the fast radio bursts we\u2019d been seeing from the distant universe, only dimmer. The two bursts we detected on May 24 were even fainter than that,\u201d she added.<\/p>\n

The study provides strong new evidence linking FRBs to magnestars, hinting that one of the universe\u2019s greatest mysteries is about to be solved.<\/p>\n

The fact that the bursts are of different strengths suggests that more than one process within the stars may produce the cosmic signals.<\/p>\n

However, questions still remain as to how magnetars produce FRBs.<\/p>\n

Dr. Kiyoshi Masui, a physicist who studies FRBs at Massachusetts Institute of Technology<\/a> in the US said earlier this year: \u201cWe\u2019re trying to piece together what it all means.\u201d<\/p>\n

\u201cWe\u2019ve got our eyes open for other magnetars, but the big thing now is to study this one source and really drill down to see what it tells us about how FRBs are made.\u201d\n <\/p><\/div>\n
