N. Korean defectors show locations of mass graves using Google Earth

Much of what happens in North Korea remains hidden from the outside world. But commercial satellite imagery and Google Earth mapping software are helping a human-rights organization take inventory of the worst offenses of the North Korean regime and identify sites for future investigation of crimes against humanity. A new report from the South Korea-based Transitional Justice Working Group (TJWG) —a non-governmental organization that tracks human-rights abuses and crimes against humanity by the world’s most oppressive regimes—details how the organization’s researchers used Google Earth in interviews with defectors from North Korea to identify sites associated with mass killings by the North Korean regime. Google Earth imagery was used to help witnesses to killings and mass burials orient themselves and precisely point out the locations of those events. Entitled “Mapping Crimes Against Humanity in North Korea: Mass Graves, Killing Sites and Documentary Evidence,” the report does not include the actual locations of what the researchers deemed to be sensitive sites out of concern that the North Korean regime would move evidence from those sites. But it does provide location data of other sites with potential documentary evidence of crimes, including police stations and other government facilities that may have records of atrocities.

After 40 years, scientists discover first-ever white dwarf pulsar

After decades of speculation, students at Warwick University have now found the first ever white dwarf pulsar. Since 1967’s discovery of the first pulsar (a rotating star that emits electromagnetic radiation), scientists have only been able to find evidence of larger neutron stars as pulsars. For those of you who aren’t astronomers, a neutron star is the last stage a celestial body goes through after a supernova before collapsing into a black hole . While scientists had yet to find any proof, many argued that the smaller dying white dwarf star could also become a pulsar. Now 40 years later, that theory has become fact. The discovery was made by Tom Marsh and Boris Gansicke from Warwick University’s Astrophysics Group alongside David Buckley from the South African Astronomical Observatory. The trio managed to spot a white dwarf pulsar 380 light years from Earth, located in the constellation of Scorpius. AR scorpii is the name they gave to the binary star that confirmed the aging hypothesis. This historic binary star is made up of both a white dwarf around the size of Earth (but around 200, 000 times denser) and a ‘nearby’ red star. With a distance only three times greater than that of the Earth and the Moon between them, the two celestial bodies are practically neighbors in galactic terms. Thanks to this relatively close proximity, the white dwarf pulsar bombards its poor red dwarf neighbor with all manner of electrical energy and particles during its two-minute rotational period.
