Astronomers at Planetary Habitability Laboratory at the University of Puerto Rico have said they have detected some very “peculiar signals” likely coming from a star just 11 light-years away.
While these peculiar signals gave rise to discussions leaning towards possible alien life, astronomers who detected these signals say that recurrent aliens hypothesis is at the bottom of many other better explanations.
The signals are coming from a red dwarf star known as Ross 128 and doesn’t seems to have any planets, but astronomers say there have been some very peculiar signals in the 10-minute dynamic spectrum that were obtained from Ross 128
Something unusual first came to light in April and May, when the team was studying a series of small and relatively cool red dwarf stars, some of which are known to have planets circling them. The signals were observed May 13 at 0053 GMT, and “consisted of broadband quasi-periodic non-polarized pulses with very strong dispersion-like features,” astronomers wrote.
According to the astronomers, the signals are not local radio frequency interferences (RFI) since they are unique to Ross 128 and observations of other stars immediately before and after did not show anything similar.
There are three main possibilities to explain the bursts: 1) they could be emissions similar to solar flares; 2) they could be emissions from another object in the field of view of Ross 128; or 3) they might be a burst from a high orbit satellite.
Since the signals are likely too dim to be picked up by other radio telescopes in the world, Mendez said that scientists at the Arecibo Observatory joined with astronomers from SETI (Search for ExtraTerrestrial Life) would use the Allen Telescope Array and the Green Bank Telescope to observe the star for a second time late Sunday.
The results of these observations could be posted at the end of this week.
