Watch the moon shadow the sun with an eclipse seen from space
"Get on board with the Solar Dynamics Observatory for a close look at a spectacular partial solar eclipse.
It's always an event when we can see a solar eclipse on Earth, but NASA's Solar Dynamics Observatory gets a much better view of the sun from its vantage point in space. The SDO caught sight of a lovely partial solar eclipse on Sunday when the moon blocked out a good chunk of our closest star.
NASA posted a GIF of the action on Monday, noting "the shadow's edge is sharp and distinct, since the moon has no atmosphere which would distort sunlight." The lunar transit lasted for one hour.
There's slight shimmy to the sun in the animated image. NASA assures us the sun was not "spooked by this near-Halloween sight," but that the shaking comes from small adjustments in the SDO's guidance system triggered by the shadow covering part of the sun.
The SDO sees the sun in extreme ultraviolet light. The red colorization helps to translate the image into something human eyes can understand. It also simply looks cool to see the sun represented as a blazing ball of fire."

DNA data offer evidence of unknown extinct human relative
VANCOUVER — Traces of long-lost human cousins may be hiding in modern people’s DNA, a new computer analysis suggests.
People from Melanesia, a region in the South Pacific encompassing Papua New Guinea and surrounding islands, may carry genetic evidence of a previously unknown extinct hominid species, Ryan Bohlender reported October 20 at the annual meeting of the American Society of Human Genetics. That species is probably not Neandertal or Denisovan, but a different, related hominid group, said Bohlender, a statistical geneticist at the University of Texas MD Anderson Cancer Center in Houston. “We’re missing a population or we’re misunderstanding something about the relationships,” he said ...
