(MSNBC) Scientists are using X-ray vision to focus on mysteries that the
comic-book heroes of the 1930s didn’t even know existed: black holes, dark
matter and the most violent explosions in the universe. The Chandra X-Ray
Observatory, ready for launch on the space shuttle Columbia, should make that
superhuman vision at least 10 times sharper.
THE TECHNOLOGICAL leap in X-ray astronomy represented by Chandra is
equivalent to the leap from the naked eye to Galileo’s first telescope, or
from ground-based observatories to the Hubble Space Telescope, says Ed Weiler,
NASA’s associate administrator for space science.
“Chandra has the potential to equal or even surpass these examples of
previous major leaps in scientific capability,” he says. “It will
study the most extreme conditions in the universe — the near environs of
black holes, the most powerful continuous sources of energy in space, known as
quasars, and it will test the laws of physics under conditions impossible to
duplicate on the earth.”
NASA ranks Chandra as one of its
four “great observatories” in space, along with Hubble, the Compton
Gamma-Ray Observatory and the yet-to-be-launched Space Infrared Telescope
Facility.
Chandra, which is named after the late Indian-American
astrophysicist Subrahmanyan Chandrasekhar, has an incredible angular resolution
of 0.25 to 0.5 arc-seconds. How incredible is that? It’s the equivalent of
reading a newspaper from a half-mile away, or seeing a stop sign from 12 miles
away. “We can make Superman jealous, I guess, with our X-ray
vision,” says Ken Ledbetter, director of the mission and payload
development division at NASA’s Office of Space Science.
