The telescope, “Spitzer” has captured a photo of a distant galaxy NGC 5866 in profile
A long beam in the center is a galaxy NGC 5866 in profile
Space telescope “Spitzer” from NASA has captured the most perfect image of the galaxy from the point of view of symmetry, which resembles a lightsaber from Star wars, if you look at it from the side. A long beam in the center is a galaxy NGC 5866 in profile.
See also the story about how NASA saw a large-scale fire century from space:
Galaxy located at a distance of 44 million light-years from Earth, and its diameter is about 60 thousand light years – slightly more than half the diameter of our milky way galaxy. Galaxy are based in our imagination as a huge spiral objects, long sleeves and a massive core in the center. But not all galaxies are oriented to us “face.” From our perspective, we see only the edge of NGC 5866, so most of its structural features invisible.
The galaxy NGC 5866 in the visible optical spectrum
“Spitzer” saw the photo in the infrared spectrum, so the red ray is emitted by the dust light. With a consistency similar to soot or dense smoke, the dust absorbs light from stars and then emits light at longer wavelengths, including the infrared range. While the blue haze is created by stars, which make up most of the mass of the galaxy.
Clean edges dust emission from NGC 5866 indicate that a very flat ring of dust surrounds the outer region of the galaxy. Rings of dust and disks are sometimes formed in the merger of galaxies, but there are no signs of bends or distortions that frequently appear in the merge result.
Scientists weighed the whole galaxy
Attempt to learn about the history and form of NGC 5866 is a challenging task due to its orientation. Our view of this galaxy is somewhat similar to the milky way: since the Earth is inside, we can only see its edge, but not entirely. But our proximity to the rest of the milky Way has allowed astronomers to reconstruct the look of our galaxy, trapped far from ideal.
A vivid example of what it’s like NGC 5866, can be seen in the Sombrero galaxy that is viewed nearly edge but tilted enough to expose the symmetric ring of dust around the galactic center.
The mysterious object hit our galaxy: what was it
“Spitzer” captured this image during its “cold” mission, which ended in 2009. But a picture published by NASA until now.
We will remind, on Earth hear the signals of the planet of the dead-zombies. Previously, NASA has published an exciting image of the approaching galaxy.
