After being hounded from her job by a torrent of online hate and abuse, journalist Talia Lavin fought back by going undercover in white supremacist chatrooms and websites. And it's a violent one. Those events are transient -- we see them for a few days or weeks and then they disappear. "If this jet was launched by our Sun, it would be way further than Pluto, making its way through the Oort cloud. Without these cookies we cannot provide you with the service that you expect.

The collision, code-named GW170817, was picked up by our planet's LIGO and Virgo gravitational wave detectors in mid-2017. That's a puzzle the researchers are trying to solve. two neutron stars smashed into each other, across different wavelengths of the electromagnetic spectrum, in the journal Monthly Notices of the Royal Astronomical Society, These telescopes work with your phone to show exactly what's in the sky. The X-ray afterglow is still visible three years after the detection of GW170817.

Curiously, though, X-rays were picked up nine days after the merger's gravitational wave was detected, and they continue to linger well past what’s typically considered normal. First, there came a burst of highly energetic gamma rays, followed by bursts of light and UV, radio and infrared signals. Georgia Secretary of State Brad Raffensperger spoke with CBSN political reporter Caitlin Huey-Burns on "Red and Blue" and explained how residents there can make sure their vote is received and counted fairly. "Whatever happens, this event is changing what we know about neutron star mergers and rewriting our models," said Troja. According to our understanding of neutron stars, it should have faded away by now. “It may be that our models are somehow incomplete and do not fully capture the complexity of these extreme phenomena, or we may be seeing something else," Troja said. ®, The Register - Independent news and views for the tech community. Today is the 36th birthday of missing American journalist Austin Tice.

She details her 18-month investigation in a new book, "Culture Warlords: My Journey Into the Dark Web of White Supremacy," and joined CBSN to discuss what she found. “In the same way we see the remnants of supernova explosions, like the Crab Nebula or the Jellyfish nebula, we may discover the remnant of a kilonova explosion. But Chandra, NASA's X-ray observatory, was still detecting X-rays at the location when it focused on the merger in February, two and a half years after it flared to life. In this whitepaper, Google discuss the problems with monoliths and why they need a different architecture to maximize their cloud investments. Two neutron stars colliding, generating gravitational waves and a huge, bright jet. These cookies are used to make advertising messages more relevant to you. GW170817 is the first neutron star merger detected by the three gravitational wave observatories stationed on Earth. and ensure you see relevant ads, by storing cookies on your device. The latest measurements show the signal has faded, but the specter of an X-ray burst is still visible and it's a little brighter than models predicted. Astronomers will turn their telescopes to GW170817 in December, presenting another opportunity to unravel the mystery in the merger. In August, scientists detected the collision of two neutron stars. For more info and to customise your settings, hit It's thought the X-rays are the result of a physical process, related to the neutron star merger, not yet observed or considered by scientists, or that the kilonova created its own shock wave through space that resulted in the delayed X-ray emissions. "We really don't know what to expect from this point forward, because all our models were predicting no X-rays," said Eleonora Troja, an astrophysicist at NASA's Goddard Space Flight Center and lead author on the study, in a press release. NetSuite spoke to senior IT executives about their technology evaluations to discover how cloud-based ERP systems support and accelerate growing organisations. Jeff Glor and his team met Tice's parents in their hometown of Houston to learn how they're hopeful about their son's return. Or perhaps the dynamics of the energy released in the aftermath of the collision are a little different to what we expect. The X-rays are incredibly energetic and bright: Troja said the emissions are 100 billion times brighter than those from the Sun, judging from the latest readings.

After a thousand days of observations, the continuing X-ray radiation from two neutron stars smashing into one another has left astronomers puzzled. You can also change your choices at any time, by hitting the “The X-rays persist for much longer, and we do not understand why,” Eleonora Troja, an associate research scientist at the University of Maryland in the US, who helped detect GW170817, told The Register. The collision, between some of the densest objects in the cosmos, produced gravitational waves and a spattering of fireworks on Aug. 17, 2017. Light from this kilonova faded about three weeks after GW170817 was observed, as expected. It may be there's an additional component of the neutron star mergers models have not previously accounted for. The collision, code-named GW170817, was picked up by our planet's LIGO and Virgo gravitational wave detectors in mid-2017. This could really change the way we search for gravitational wave mergers, and the idea of discovering a new type of celestial source is very exciting."

The incredible crash, some 130 million light-years away, spilled a heady mix of electromagnetic signals into space as well as the gravitational wave we detected here on Earth. Explosive neutron star collision is still emitting X-rays, puzzling astronomers When two neutron stars smashed into each other , about 130 million light-years from Earth, the universe lit up. We measure how many people read us, One remarkable feature of the merger was its kilonova, which immediately followed an initial gamma-ray burst. After a thousand days of observations, the continuing X-ray radiation from two neutron stars smashing into one another has left astronomers puzzled. That was the case with GW170817. We have never seen such a thing before, it only exists in our theories and models. But in a new study, published Monday in the journal Monthly Notices of the Royal Astronomical Society, researchers have studied the neutron-star-on-neutron-star impact, designated GW170817, and discovered that 1,000 days later, the X-ray signal was still detectable. Indeed, a paper, of which Troja is lead author, was published in the Monthly Notices of the Royal Astronomical Society on Monday, and suggests the neutron star collision created another neutron star that’s been emitting x-rays for all these years. Well, sorry, it's the law. A neutron star collision I have nothing left to lose You took your time to choose Then we told each other With no trace of fear that...
