Some “peculiar signals” have been noticed coming from a star 11 light-years away, scientists in Puerto Rico said.
The mystery has gripped the Internet as speculation mounts about the potential for a discovery of alien life on the red dwarf star known as Ross 128, despite the best attempts of astronomers to put such rumors to rest.
“In case you are wondering, the recurrent aliens hypothesis is at the bottom of many other better explanations,” said a blog post by Abel Mendez, director of the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.
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 orbiting them.
Ross 128 is not known to have planets, but “we realized that there were some very peculiar signals in the 10-minute dynamic spectrum that we obtained from Ross 128.”
The signals were observed on May 13 at 12:53am GMT and “consisted of broadband quasi-periodic, non-polarized pulses with very strong dispersion-like features,” he wrote. “We believe that the signals are not local radio frequency interferences, 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:
They could be emissions similar to solar flares. They could be emissions from another object in the field of view of Ross 128. Or they might be a burst from a high-orbit satellite, Mendez wrote.
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 and astronomers from the Search for ExtraTerrestrial Life (SETI) would use the Alien Telescope Array and the Green Bank Telescope to observe the star for a second time on Sunday.
The results of these observations should be posted by the end of next week, he said.
“I have a Pina Colada ready to celebrate if the signals result to be astronomical in nature,” Mendez said.
As the sun sets on another scorching Yangon day, the hot and bothered descend on the Myanmar city’s parks, the coolest place to spend an evening during yet another power blackout. A wave of exceptionally hot weather has blasted Southeast Asia this week, sending the mercury to 45°C and prompting thousands of schools to suspend in-person classes. Even before the chaos and conflict unleashed by the military’s 2021 coup, Myanmar’s creaky and outdated electricity grid struggled to keep fans whirling and air conditioners humming during the hot season. Now, infrastructure attacks and dwindling offshore gas reserves mean those who cannot afford expensive diesel
Does Argentine President Javier Milei communicate with a ghost dog whose death he refuses to accept? Forced to respond to questions about his mental health, the president’s office has lashed out at “disrespectful” speculation. Twice this week, presidential spokesman Manuel Adorni was asked about Milei’s English Mastiff, Conan, said to have died seven years ago. Milei, 53, had Conan cloned, and today is believed to own four copies he refers to as “four-legged children.” Or is it five? In an interview with CNN this month, Milei referred to his five dogs, whose faces and names he had engraved on the presidential baton. Conan,
French singer Kendji Girac, who was seriously injured by a gunshot this week, wanted to “fake” his suicide to scare his partner who was threatening to leave him, prosecutors said on Thursday. The 27-year-old former winner of France’s version of The Voice was found wounded after police were called to a traveler camp in Biscarrosse on France’s southwestern coast. Girac told first responders he had accidentally shot himself while tinkering with a Colt .45 automatic pistol he had bought at a junk shop, a source said. On Thursday, regional prosecutor Olivier Janson said, citing the singer, that he wanted to “fake” his suicide
Indian Prime Minister Narendra Modi reaffirmed his pledge to replace India’s religion-based marriage and inheritance laws with a uniform civil code if he returns to office for a third term, a move that some minority groups have opposed. In an interview with the Times of India listing his agenda, Modi said his government would push for making the code a reality. “It is clear that separate laws for communities are detrimental to the health of society,” he said in the interview published yesterday. “We cannot be a nation where one community is progressing with the support of the Constitution while the other
