From BBC News:
Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada.
The precise nature and origin of the blasts of radio waves is unknown.
Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away.
Such an event has only been reported once before, by a different telescope.
“Knowing that there is another suggests that there could be more out there,” said Ingrid Stairs, an astrophysicist from the University of British Columbia (UBC).
“And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles – where they’re from and what causes them.”
The CHIME observatory, located in British Columbia’s Okanagan Valley, consists of four 100-metre-long, semi-cylindrical antennas, which scan the entire northern sky each day.
The telescope only got up and running last year, detecting 13 of the radio bursts almost immediately, including the repeater.
It’s not Lunar New Year yet, but there is something new on the moon. In a major milestone for space exploration, China announced that its lunar program has successfully soft-landed a probe on the far side of the moon, making it the first country to do so. The historic landing was reported by Xinhua, China’s…

YouTube channel SpaceTime has been running an excellent series on String Theory and explains, in simplistic-yet-detailed language, what it is and how it’s taken the science world by storm over the past thirty years.
Also (for some reason WordPress are not allowing me to embed more than one video) How to Detect Extra Dimensions, Why String Theory is Right and Why String Theory is Wrong.
My favourite YouTube channel just got even better. New series.

US space agency Nasa has launched its mission to send a satellite closer to the Sun than any before.
The Parker Solar Probe rocket lifted off from Cape Canaveral, Florida.
The probe is set to become the fastest-moving manmade object in history. Its data promises to crack longstanding mysteries about the Sun’s behaviour.
It is the first space craft to be named after a living person – astrophysicist Eugene Parker, 91, who first described solar wind in 1958.
“Wow, here we go! We’re in for some learning over the next several years,” he said after watching the lift-off from the scene. The University of Chicago professor said he had been biting his nails in anticipation.

The US National Science Foundation (NSF) is hosting an announcement today to reveal exciting findings from its IceCube observatory at the South Pole. At 11am EDT (3pm GMT) today, they’ll be streaming live from the NSF headquarters in Virginia, as scientists discuss a groundbreaking discovery in astronomy. The NSF said that the announcement concerns “multi-messenger astrophysics findings” from IceCube.
More than 20 observatories took part in the research, and leading astrophysicists from these will be present at the event. Aside from that, no other details have been revealed.
NASA announced yesterday that its highly anticipated James Webb Space Telescope is delaying its launch — again. It was announced in March that the mission would be delayed until 2020, which is already two years past its original launch date of October 2018. But after accepting the recommendations of an independent review board, NASA has…

NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet’s surface and subsurface.
The new findings – “tough” organic molecules in three-billion-year-old sedimentary rocks near the surface, as well as seasonal variations in the levels of methane in the atmosphere – appear in the June 8 edition of the journal Science.
Organic molecules contain carbon and hydrogen, and also may include oxygen, nitrogen and other elements. While commonly associated with life, organic molecules also can be created by non-biological processes and are not necessarily indicators of life.
A new report in The Astrophysical Journal claims that two stars may have just collided to create a black hole. If this is true, it may radically alter our understanding of how these super structures are formed. The alternative is potentially just as crazy sounding, that two neutron stars can fuse. Either way, something very […]
