Astronomy: October 2017 Archives

Something Visited Our Solar System From Interstellar Space, NASA

"A small, recently discovered asteroid -- or perhaps a comet -- appears to have originated from outside the solar system, coming from somewhere else in our galaxy. If so, it would be the first "interstellar object" to be observed and confirmed by astronomers. This unusual object -- for now designated A/2017 U1 -- is less than a quarter-mile (400 meters) in diameter and is moving remarkably fast. Astronomers are urgently working to point telescopes around the world and in space at this notable object."

NASA Internal Memo: Next Steps for WFIRST Program

"I have reviewed the findings of the independent review team and have accepted them. As a result, I believe reductions in scope and complexity are needed. I am directing the Goddard Space Flight Center to study modifying the current WFIRST design, the design that was reviewed by the WIETR, to reduce cost and complexity sufficient to have a cost estimate consistent with the $3.2B cost target set at the beginning of Phase A."
