[center]Where is the Largest Protected Park on Earth?[/center]
The largest protected park on Earth is Greenland‘s Northeast
Greenland National Park, which is approximately 357,917 square
miles (927,000 square km) or about two times the size of the
state of California. It was established in 1974 and contains an
estimated 40% of the worldwide population of musk ox. Other
animal species that live in Northeast Greenland National Park
include walruses, snowy owls, polar bears, and arctic foxes. Due
to its Arctic location, the park area barely reaches above
freezing temperatures in the summertime, has little sunlight,
and is in extreme darkness for around four months of the year.
More about nature reserves:
•Australia’s Great Barrier Reef Marine Park is home to the Great
Barrier Reef coral reef, which is the largest living structure
in the world.
•The largest marine reserve on Earth is the Chagos Marine
Protected Area, located in the British Indian Ocean
Territory--it’s around twice the size of the United Kingdom and
contains the biggest coral atoll, or circular-shaped coral
formation, in the world.
•Greenland’s Northeast Greenland National Park is larger in size
than all but 30 countries in the world.

[center]HD 162826: Astronomers Discover Second Sun

Astronomers from the United States, Russia and Australia have
discovered the first true solar sibling – HD 162826.
D 162826, a star born in the same star cluster as our Sun, is
located in the constellation Hercules, about 110 light-years
away from Earth. It has a mass about 1.15 times that of the Sun.
The star is not visible to the unaided eye but can be seen with
low-power binoculars, not far from Vega.
The astronomers led by Dr Ivan Ramirez from the University of
Texas at Austin identified HD 162826 as our Sun’s sibling by
following up on 30 possible candidate stars. In addition to
chemical analysis, they also analyzed information about orbits
of these stars.
Considering both chemistry and orbits narrowed the field of
candidates down to one – HD 162826.
“No one knows whether this star hosts any life-bearing planets,”
said Dr Ramirez, who reported the discovery in the Astrophysical
Journal (arXiv.org version).
Dr Ramirez’s team has ruled out any massive planets orbiting
close to the star.
“It’s unlikely that a Jupiter analog orbits the star,” Dr
Ramirez said.
However, he and his colleagues do not rule out the presence of
smaller terrestrial planets.
“The finding of a single solar sibling is intriguing, but the
project has a larger purpose: to create a road map for how to
identify solar siblings, in preparation for the flood of data
expected soon from surveys such as ESA’s Gaia.”
Gaia will provide accurate distances and proper motions for a
billion stars, allowing scientists to search for solar siblings
all the way to the center of our Milky Way Galaxy.
“The number of stars that we can study will increase by a factor
of 10,000,” Dr Ramirez said.
“Don’t invest a lot of time in analyzing every detail in every
star. You can concentrate on certain key chemical elements that
are going to be very useful. These elements are ones that vary
greatly among stars, which otherwise have very similar chemical
compositions. These highly variable chemical elements are
largely dependent on where in the Galaxy the star formed.”
“We want to know where we were born. If we can figure out in
what part of the Galaxy the Sun formed, we can constrain
conditions on the early Solar System. That could help us
understand why we are here,” Dr Ramirez said.
Once many more solar siblings have been identified, astronomers
will be one step closer to knowing where and how the Sun formed.
