Mystery over identity of dead boy found on beach

  Mystery over identity of dead boy found on beach Mystery surrounds the death of a young child whose body was discovered on a beach in Texas. The boy, who is believed to be three to five years old, was found on the island city of Galveston on Friday night with no clues as to his identity.Police have been unable to trace his parents or any family members, and no one has come forward to report a missing child. © Getty Police are treating the case as murder Pending the results of a post-mortem examination, detectives are treating the death as a homicide and described it is "an extremely unusual case for Galveston Island".

LOS ANGELES - A small asteroid or comet that has been spotted racing through our solar system may have come from elsewhere in the galaxy, US space scientists say, possibly marking the first such interstellar visitor observed from Earth. The mystery object , so far known only as A/2017 U 1

The mystery object, so far known only as A/2017 U1, was discovered earlier this month by a researcher using a sophisticated telescope system at the University of Hawaii that continually scans the universe for such phenomenon.

"We have been waiting for this day for decades," said Paul Chodas, manager of the National Aeronautics and Space Administration's Center for Near Earth Object Studies at the Jet Propulsion Laboratory in Pasadena, California.

"It's long been theorized that such objects exist -- asteroids or comets moving around between the stars and occasionally passing through our solar system -- but this is the first such detection," Chodas said.

The mass, a quarter mile (400 meters) in diameter, quickly stood out for scientists because of its extreme orbit, coming from the direction of the constellation Lyra, almost directly above the elliptical plane where the planets and other asteroids orbit the sun.

Researchers observe the first known interstellar comet

  Researchers observe the first known interstellar comet To date, every comet humanity has seen inside the Solar System has come from the Solar System, whether it's the Kuiper Belt or the billions of comets believed to make up the Oort Cloud. These are preliminary findings, and there's more work to be done before researchers can be completely sure. If they confirm the orbit, though, it'll expand our understanding of space: we'll have tangible evidence that star systems can "swap" comets if the circumstances are right. The concept wasn't far-fetched given that comets are fairly common, but it's good to have tangible proof.

LOS ANGELES (Reuters) - A small asteroid or comet that has been spotted racing through our solar system may have come from elsewhere in the galaxy, U.S. space scientists say, possibly marking the first such interstellar visitor observed from Earth. The mystery object , so far known only as A/2017

It crossed under that plane just outside Mercury's orbit on Sept. 2 before being slung by the sun's massive gravity into a sharp turn under our solar system. The closest the object came to Earth was about 15 million miles away on Oct. 14.

"It is going extremely fast and on such a trajectory that we can say with confidence that this object is on its way out of the solar system and not coming back," NASA's Davide Farnocchia said. Astronomers were urgently tracking A/2017 U1 with telescopes as it makes its journey through our solar system, hoping to use that data to confirm the object's interstellar origins and learn what they can about its composition.

If the object is formally established as the first of its kind spotted from Earth, rules for naming it would have to be set out by the International Astronomical Union, NASA scientists said.

NASA has found another 20 promising planets for humans to colonize .
An international team of scientists has found 20 more exoplanets that might sustain human life.  The space telescope, Kepler, was launched in 2009 with the specific mission to find extrasolar planets. And scientists have used its data to confirm thousands of them. Kepler broke in 2013, but the area of space it recorded over the four years it was operational contained over 150,000 stars, so there’s still a lot of data to go through.
