have discovered one of the oldest objects in the universe.
It’s
what they call a black hole. They found it using two telescopes on Mauna Kea.
The
light detected in Hawaii left the black hole 13 billion years ago, says Gemini
Observatory scientist Paul Hirst.
He
says the discovery provides information about the early universe, even back to
its creation, the so-called “big bang.”

Hirst
says the discovery was a team effort. First, a British telescope on Mauna Kea
detected something promising. The data was then passed along to a team using
the Gemini North telescope, its neighbor on Mauna Kea.
Getting
just two hours of “telescope time” on Gemini North to confirm the discovery was
an undertaking. Hirst says “telescope time” is competitive and scientists must
write a proposal about why they should be allotted time.
When
the team got its two hours – one night several months ago – the significance of
the data coming in was immediately apparent to astronomers on night watch at
the telescope.

The
discovery by 17 black hole researchers was published Thursday in the science journal
Nature.
