"The brightness difference between the two stars made it even more
difficult to resolve them," said astronomer Howard Bond of the Space Telescope
Science Institute, Baltimore. Knowing their mass is the most important ingredient in
this understanding.

WASHINGTON, By stretching the capabilities of
NASA's Hubble Space Telescope to the limit, astronomers photographed Polaris,
the close companion of the North Star, for the first time.

"With Hubble, we've pulled the North Star's companion out of the shadows and
into the spotlight," he said.nasa.

The North Star is thought to be a steady, solitary point of light that
guided sailors for ages, but there is more to this star than meets the eye. It also supports research aimed
toward understanding the geochemical nature of the solar system's bodies, such
as planets, Earth 's moon, satellites of the outer planets, and small bodies.

"It is that clear vision that makes these types of discoveries possible," he
added. The
companion proved to be less than two-tenths of an arcsecond from Polaris.

Polaris is a super-giant more than two thousand
times brighter than the sun, while its companion is a main-sequence star.
"Our ultimate goal is to get the accurate mass for Polaris," Evans said.

The researchers plan to continue observing the Polaris system for several
years.

"The star we observed is so close to Polaris that we needed every
available bit of Hubble's resolution to see it," said astronomer Nancy Evans
of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass., for a grant to support the agency's Cosmochemistry Research
Program .
The research also supports the Vision for Space Exploration, NASA's long-
term plan to return astronauts to the moon and extend exploration to Mars and
beyond.

"Hubble's exceptional pointing capabilities combined with the wonderful
performance of its instruments allow scientists to see the universe in finer
detail than ever before," said Michael Moore, NASA's Hubble program executive. While one companion is easily
viewed with small telescopes , the other hugs Polaris so tightly that it has
never been seen until now. At the system's distance of 430 light-years from Earth,
that translates into a separation of about 2 billion miles. Astronomers want to determine the mass of Polaris,
because it is the nearest Cepheid variable star.
The program also covers cosmochemical studies concerned with the formation and
chemical development of the solar system.

"To do that, the next milestone is to measure the motion of the companion in
its orbit," she added. Cepheids' brightness
variations are used to measure the distances of galaxies and the expansion
rate of the universe .
