"Astronomers have built a new astro-camera that, when
fitted onto the largest observatories on Earth, can snap photos of the universe
twice as sharp as the famed Hubble Space Telescope.<br />
<br />
With the newly developed technology, giant telescopes can reach their
theoretical limits of resolution in visible light —something that was just not
possible, until now, because of atmospheric turbulence causing blurry visible
light images. (Related: The Largest Baby Star, Ever?)<br />
<br />
“It was very exciting to see this new camera make the night sky look sharper
than has ever before been possible,” said Laird Close, the project’s principal
scientist at the University of Arizona in a press statement.<br />
<br />
“We can, for the first time, make long-exposure images that resolve objects
just 0.02 arcseconds across — the equivalent of a dime viewed from more than a
hundred miles away. At that resolution, you could see a baseball diamond on the
Moon,” said Laird Close, lead astronomer for the MagAO project.<br />
<br />
Called Adaptive Secondary Mirror (ASM), this new imaging technology sits high
above the primary mirror of the telescope, working to counter the atmospheric
turbulence by changing the shape of its thin curved glass mirror 1,000 times
each second.<br />
<br />
“As a result, we can see the visible sky more clearly than ever before,” said
Close. “It’s almost like having a telescope with a 21-foot mirror in space.”<o:p></o:p></div>
