Thanks to the ESO for the image of
the Helix Nebula, also NASA, ESA and the Hubble Heritage Team for the image of NGC 3808B (ARP 87).
As seen by NASA's Spitzer Space Telescope,
the Helix Nebula appears to peer out from space in the shape of a giant eye.
CD - 23 17699 is located about 26.6 light - years (ly) away from our Sun, Sol, in the southwest corner (23:00:16.1 - 22:31:27.6, ICRS 2000.0) of Constellation Aquarius, the Water Bearer — southwest of Skat (Delta Aquarii), northwest of Fomalhaut (Alpha Piscis Austrini), north of Epsilon Piscis Austrini, and east of
the Helix Nebula.
One landmark example is the major effort to tackle common challenges in the era of big data:
the Helix Nebula project, for instance, brought together three EIROforum partners — CERN, ESA and EMBL — along with private data service providers to deliver cloud computing services for science.
The new near - infrared image of
the Helix Nebula, showing comet - shaped knots within, was released July 2, 2009.
This is a color enhanced version of the infrared signal to make the Double
Helix Nebula's features easier to see.
The Helix Nebula, for example, resembles a doughnut in colorful images.
He admits to being fascinated by the fine, comet - shaped knots recently observed inside
the Helix nebula - they are clumps of molecular gas that escaped being ionized by the star's ultraviolet blast - but only because they relate to the big picture.
The main ring of
the Helix Nebula is about 2 light - years across, about half the distance from our sun to the nearest star.
A new infrared image of
the Helix Nebula in the constellation Aquarius is shedding light on the enigmatic object's structure.
In March of 2006, astronomers reported an 80 light year - long nebula near the center of the Milky Way Galaxy, the Double
Helix Nebula, which is, as the name implies, twisted into a double spiral shape.
Not exact matches
The three bands then correspond to the galactic center of a galaxy in the Hubble field and the interacting galaxy, the center of a bright star in the Magellanic cloud and a star cluster and the last band corresponds to the white dwarf in the
Helix and Cat's eye
nebulae.
And inside some of the
nebulas - the
Helix or Eskimo, say - you see peculiar knots and clumps of gas that look like comets plunging in toward the star.
