Telegram and Signal messaging services are both down

  Telegram and Signal messaging services are both down Two of the more popular encrypted messaging apps, Signal and Telegram, are both experiencing service issues today. Telegram appears to be inaccessible for users in Europe, the Middle East, and North Africa, while Signal has been down for hours across Europe, the US, Asia, and Australia. “Some of our users in Europe and the MENA region are currently experiencing connection issues,” says Telegram spokesperson.

Updated | Scientists have spotted three new fast radio bursts ( FRBs ) in less than two weeks—and one is the brightest ever observed. FRBs are mysterious signals that appear to come from deep space . Twinkling for just milliseconds, their sources are, as yet, unknown.

FRBs are mysterious signals that appear to come from deep space. Twinkling for just milliseconds, their sources are, as yet, unknown.

Astronomers use the world’s largest radio telescopes to detect the elusive flashes. But even these capture relatively small slivers of sky, so astronomers have to be lucky to catch the bursts. So far, just 33 have been spotted since the first in 2001.

The three latest bursts were spied on March 1, March 9 and March 11 using the Parkes Observatory in Australia, according to the FRB Catalogue. They were recorded in the Astronomer’s Telegram.

Alien life or astrophysics?

The Breakthrough Listen project spotted the March 1 FRB while hunting for intelligent alien life. “BL is foremostly a search for technologically-capable life beyond Earth; however, a real-time search for FRBs runs in tandem,” the team wrote in the Telegram.

Danny Price of the Berkeley SETI Research Center and one of the astronomers behind the March 1 spot wrote in a blog post that, while the team would love aliens to be behind the signals, they need to “rule out all plausible astrophysical theories first.”

Extremely bright FRB

Last Friday (March 9), saw the brightest FRB ever observed. It had the "highest signal-to-noise ratio" ever recorded, researcher Stefan Oslowski of the Swinburne University of Technology in Melbourne, Australia wrote in a tweet. Oslowski and colleagues also recorded the March 11 FRB, which occurred within 50 hours of March 9's.

Aliens Would Be Dead Before Their Messages Reach Us

  Aliens Would Be Dead Before Their Messages Reach Us Radio waves are fast, but not fast enough to reach us before a civilization goes extinct.That assessment is the conclusion of an unpublished study posted on arXiv. The study expands on the current mathematical model used to consider the search for extraterrestrial intelligence, or SETI. That model, known as the Drake equation, was created by astronomer and astrophysicist Frank Drake in 1961 to estimate the number of planets in the galaxy that might harbor extraterrestrial intelligence.

Scientists detect strange repeating radio burst on the other side of the cosmos Fast radio bursts , or FRBs , have baffled scientists for the past decade. Just a few years ago we didn’t even know that the cosmic phenomena known as fast radio bursts (FRB) — rare, bright , and inexplicable signals from

Unknown source

Although their sources remain unknown, scientists are learning more about FRBs all the time. One of the signals has been found to repeat, which has let scientists take a deeper look at the evasive bursts.

Earlier this year, researchers reported the flashing signal might be caused by a neutron star sitting in an extreme environment like a powerful nebula or the remains of a supernova.

Some astronomers predict that all FRBs repeat, but most of their flashes are just too dim to see. Maura McLaughlin, an astronomer from West Virginia University in Morgantown, thinks the March 9 signal could be a promising target for further bursts, New Scientist reports. She said: “If we believe that all FRBs repeat and it’s just a matter of waiting long enough for one to be bright enough, we should be able to detect more pulses from this one because it’s so bright.”

McLaughlin thinks far more FRB discoveries are on the cards. “Everyone’s sort of jumping on this bandwagon of looking for FRBs in the background all the time no matter what else is going on,” she said. “This should lead to a huge uptick in detections in the next year or so.”

Justin Bieber's Blonde Mystery Woman Identified: Meet Baskin Champion! .
Justin Bieber may have moved on from his on-again, off-again relationship with Selena Gomez. On Tuesday night, 24-year-old Bieber was spotted at singer Craig David's concert at The Roxy in West Hollywood, California, with a blonde woman, who has now been identified as 22-year-old model Baskin Champion. And the two weren't hiding their close relationship -- an eyewitness told ET that Bieber wrapped his arm around her waist during one song, and that she was dancing up on him throughout the show.
