This is the first neutron star in which an extended signal has been seen only in infrared light. The remarkable discovery was made by a team of international researchers who have offered two possible explanations for the extended infrared signal – a dusty disk or an energetic wind known as a pulsar wind.
Scientists observed an extended area of infrared emissions around this particular neutron star, which belongs to a group of seven nearby X-ray pulsars — nicknamed ‘the Magnificent Seven.’
Lead author of the study Bettina Posselt said one possible explanation is that there is a disk of material – most likely dust – surrounding the pulsar.
“Such a disk would be composed of matter from the progenitor massive star. Its subsequent interaction with the neutron star could have heated the pulsar and slowed its rotation,” Posselt said.
This phenomenon is known as supernova fallback disk, and if confirmed as the source of the signal it could change our general understanding of neutron star evolution, according to Posselt.
Another theory is that the emission was caused by a pulsar wind slamming into the neutron star as it sped through interstellar space. The shocked particles would then emit synchrotron radiation, causing the extended infrared signal that we see. read more…
The French Navy’s newest frigate, FS Auvergne, fired rockets around 8pm GMT Monday, the Russian military said. “Airspace control has recorded rocket launches from the French frigate Auvergne,” the ministry’s statement read. The Auvergne is deployed in the Mediterranean Sea, off the coast of Syria.
Auvergne is a ‘European multi-purpose frigate’ (FREMM) which entered the service of the French Navy in February this year. Prior to its official commissioning, the Aquitaine class warship witnessed deployment across the globe, including the Mediterranean Sea, the Indian Ocean, the Persian Gulf, the South China Sea and the Pacific Ocean.
The launch was detected around the same time as air traffic controllers at the Khmeimim Air Base “lost contact” with a military Il-20 aircraft during an attack of Israeli F-16 fighters on Latakia. Fourteen people were on board the plane at the time of the disappearance. A search and rescue mission is underway.
The IDF has refused to comment on the report. Despite the fact that Israel rarely acknowledges striking specific targets inside Syria, earlier this month the IDF admitted to hitting at least 202 “Iranian targets” in the country. read more…
Sunspot Solar Observatory to reopen Monday morning 9/17/18 after FBI investigation
The visitor’s centre of the Sunspot Solar Observatory, which is located near the Sacramento Mountains, apparently no longer faces a security threat and has reopened. Staff at the observatory confirmed to RT that the grounds and visitor’s centre are open to the public, however they are still awaiting permission from authorities to reopen the observatory.
The solar observatory – equipped with a one-of-a-kind telescope that produces some of the sharpest images of the sun – found itself making global headlines after its abrupt closure by the FBI on September 6.
The lack of details over the observatory’s shock closure sparked a flurry of speculation and conspiracy theories online – and now the internet wants answers: is the government trying to cover up evidence of aliens, imminent solar flares, or even the sun dying?
The FBI has remained tight-lipped, declining to comment or elaborate on the closure and evacuation of the space research facility, as well as a dozen residents living around the site, and a nearby post office.
Otero County Sheriff Benny House detailed to local media just how intense it was having the FBI descend on the observatory. “There was a Blackhawk helicopter, a bunch of people around antennas and work crews on towers, but nobody would tell us anything,” he said, adding that the FBI was “secretive” and there “there was a lot of stuff going on” at the observatory.
In a statement to announce Monday’s reopening, the Association of Universities for Research in Astronomy (AURA) said the closure was due to a concern “that a suspect in the investigation [of criminal activity at Sacramento Peak] potentially posed a threat to the safety of local staff and residents. For this reason, AURA temporarily vacated the facility and ceased science activities at this location.”
AURA added that, “given the significant amount of publicity the temporary closure has generated and the consequent expectation of an unusual number of visitors to the site,” additional security services would help patrol the reopened facility. The move comes as curious conspiracy theorists crossed police lines during the closure to take a peek at the hush-hush goings-on taking place at the observatory. read more…
