Our Space has been a mystery for
long and the journey to decode its
secrets has intrigued many. Ever
wondered why our heavenly bodies
looked so spectacular and
breathtaking. Telling us the story are
the stunning photos of celestial
objects, many of which are several
light-years away. Track the recent
research on this field, which has
been a total enigma for all of
mankind. From the recent comets,
to striking craters to the 'Eye of the
God' - here's an attempt at
unraveling the mysteries of the
universe...
Recently, a brilliant spectacle of the 'Eye of
God' was observed by astronomers. The
cosmic formation is a mixture of gas and dust
that comes from a fading central star. Its size
is believed to be quarter the size of the moon.
The 'Eye of God' image lies close to 700 lightyears away and it is present in the
constellation of Aquarius. It is believed that
our solar system to could meet a similar fate
five billion years from now. In this image
provided by NASA shows a newly expanded
image of the Helix nebula lending a festive
touch to the fourth anniversary of the launch
of NASA's Spitzer Space Telescope. This
spectacular object, a dying star unraveling
into space, is a favorite of amateur and
professional astronomers alike. Spitzer has
mapped the expansive outer structure of the
six-light-year-wide nebula, and probed the
inner region around the central dead star to
reveal what appears to be a planetary system
that survived the star's chaotic death throes.
Spitzer launched from Cape Canaveral, Fla.
This image provided by NASA
shows a Hubble Space Telescope
image of thousands of sparkling
young stars nestled within the
giant nebula NGC 3603. This stellar
"jewel box" is one of the most
massive young star clusters in the
Milky Way Galaxy. NGC 3603 is a
prominent star-forming region in
the Carina spiral arm of the Milky
Way, about 20,000 light-years
away. This latest image from
NASA's Hubble Space Telescope
shows a young star cluster
surrounded by a vast region of
dust and gas. The image reveals
stages in the life cycle of stars.
This photo from the Hubble Space
Telescope, supplied by NASA and the
European Space Agency shows bright
blue newly formed stars that are
blowing a cavity in the center of a starforming region known as N90 that has
fascinated scientists. The high energy
radiation blazing out from the hot
young stars in N90 is eroding the outer
portions of the nebula from the inside,
as the diffuse outer reaches of the
nebula prevent the energetic outflows
from streaming away from the cluster
directly. Because N90 is located far from
the central body of the Small
Magellanic
Cloud,
numerous
background galaxies in this picture can
be seen, delivering a grand backdrop for
the stellar newcomers. The dust in the
region gives these distant galaxies a
reddish-brown tint.
Using
NASA's
Chandra
X-ray
Observatory, scientists have created a
stunning new image of one of the
youngest supernova remnants in the
galaxy. This new view provided by NASA
shows the debris of an exploded star
that helps astronomers solve a longstanding mystery, with implications for
understanding how a star's life can end
catastrophically and for gauging the
expansion of the universe. Chandra's
latest image marks a new phase in
understanding the object now known as
Kepler's supernova remnant. By
combining nearly nine days of Chandra
observations,
astronomers
have
generated an X-ray image with
unprecedented detail of one of the
brightest recorded supernovas in the
Milky Way galaxy.
This image provided by NASA's Hubble
Space Telescope shows the galaxy Zwicky
18. NASAs Hubble Space Telescope has
found the galaxy is the equivalent of the
painting of Dorian Gray, a portrait in an
Oscar Wilde novel that appears
mysteriously to age. Like the fictional
painting, the galaxy I Zwicky 18 appears
to look older the more astronomers
study it. New Hubble data have quashed
that possibility. The telescope found faint
older stars contained within the galaxy,
suggesting its star formation started at
least one billion years ago and possibly
as much as 10 billion years ago. The
galaxy, therefore, may have formed at
the same time as most other galaxies.
Although the galaxy is not as youthful as was once believed, it is certainly
developmentally challenged and unique in the nearby universe, said
astronomer Alessandra Aloisi from the Space Telescope Science Institute and
the European Space Agency in Baltimore, Md., who led the new study.
This image provided by NASA shows
the striking Maunder crater lying at
approximately 50 degrees South and
2 degree East, in the Noachis Terra
region on Mars. The High Resolution
Stereo Camera (HRSC) on ESA's Mars
Express orbiter took pictures of the
Noachis Terra region during orbits
2412, with a ground resolution of
approximately 15 metres per pixel.
The sun illuminates the scene from
the north-east (top left in the image).
Maunder crater, named after the
british astronomer Edward W.
Maunder, is located halfway between
Argyre Planitia and Hellas Planitia on
the southern highlands of Mars.
In this image provided by
NASA shows the very deep
image taken with the
NASA/ESA Hubble Space
Telescope shows the spiral
galaxy NGC-4921 along with
a spectacular backdrop of
more distant galaxies. It
was created from a total of
80
separate
pictures
through yellow and nearinfrared filters.
This image provided by NASA
shows the spiral galaxy Messier
101 and is a composite of views
from
the
Spitzer
Space
Telescope,
Hubble
Space
Telescope, and Chandra X-ray
Observatory. The red color
shows Spitzer's view in infrared
light. It highlights the heat
emitted by dust lanes in the
galaxy where stars can form.
The yellow color is Hubble's
view in visible light.
Most of this light comes from stars, and they trace the same spiral
structure as the dust lanes. The blue color shows Chandra's view in Xray light. Such composite images allow astronomers to see how
features seen in one wavelength match up with those seen in another
wavelength.
This image provided by NASA
shows an artist concept of an
Iridium satellite in earth
orbit.
Two
big
communications
satellites
collided in the first-ever crash
of its kind in orbit over
Siberia Tuesday Feb. 10,
2009, shooting out a pair of
massive debris clouds and
posing a slight risk to the
international space station.
The collision involved an Iridium commercial satellite, which was
launched in 1997, and a Russian satellite launched in 1993 and
believed to be nonfunctioning.

Kourou, French Guiana. The
Ariane-5 rocket shuttled one
satellite
for
Eutelsat
Communications,
a
French
operator of satellites, and the
other for global operator SES. The
mission also launched two microsatellites
for
the
French
government's arms procurement
agency, the DGA.
