NASA reports visitor from another solar system

A study from the Max Planck Institute in Germany published Thursday, Sept. 12, 2019, in the journal Science uses a new technique to come up with a rate that the universe is expanding that is nearly 18% higher than the number scientists had been using since the year 2000.

CAPE CANAVERAL, Fla. (AP) — The solar system may have another foreign guest.

Both NASA and the European Space Agency are reporting that a newly discovered comet zooming toward the sun is likely from another star.

Astronomers said Thursday it’s traveling 93,000 mph, so fast it likely originated outside our solar system. It’s 260 million miles from the sun and getting closer.

It’s expected to completely sidestep Earth, remaining beyond Mars’ orbit.

Scientists predict the comet will hurtle past the sun in December and keep going until it’s back in interstellar space. It should be visible with professional telescopes well into next year. Its nucleus is estimated between 1.2 miles and 10 miles across.

Officially known as C/2019 Q4, the comet was discovered two weeks ago by an amateur astronomer at an observatory on the Crimean Peninsula. In 2017, a telescope in Hawaii spied our first known interstellar visitor.

With another so soon, these interstellar passers-by could be more common than thought.

“We are now working on getting more observations of this unusual object,” Marco Micheli of ESA’s Near-Earth Object Coordination Center said in a statement. “We need to wait a few days to really pin down its origin with observations that will either prove the current thesis that it is interstellar, or perhaps drastically change our understanding.”
