Mystery of 'alien megastructure' is baffling scientists

By Patrick Jones, Buzz60

Scientists are digging deep into their creative sides to figure out the mystery of Boyajian's star.

The rapidly dimming star has dimmed dramatically over the past seven years, once by as much as 22%.

But the dimming is too great to be caused by an orbiting planet, so scientists are getting creative with other possible explanations.

Right now the leading theory is that the dimming is caused by an interstellar cloud passing between earth and the star

However, even that theory is shaky.

Jason Wright, an astronomer from Penn State, says "that would have to be some crazy interstellar cloud," adding, "I think it's very likely we haven't heard the right answer yet."

If they need new options they should start asking kids, that's where real creativity lives.

ANTARCTICA - OCTOBER 31: A section of ice near the coast of West Antarctica is viewed from a window of a NASA Operation IceBridge airplane on October 31, 2016 in-flight over Antarctica. NASA's Operation IceBridge has been studying how polar ice has evolved over the past eight years and is currently flying a set of 12-hour research flights over West Antarctica at the start of the melt season. Researchers have used the IceBridge data to observe that the West Antarctic Ice Sheet may be in a state of irreversible decline directly contributing to rising sea levels. NASA and University of California, Irvine (UCI) researchers have recently detected the speediest ongoing Western Antarctica glacial retreat rates ever observed.
