Best Art in the Universe? Hubble Space Telescope's Amazing Pics From 2010
(Dec. 15) -- You might think that taking highly detailed photographs of the darkest corners of the universe would be a purely scientific job. Turns out, there's an art to it.
For the past 20 years, the Hubble Space Telescope has been orbiting the planet and wowing earthlings with breathtaking images of outer space, from jaw-dropping pictures of clusters of newborn stars to fantastic photos of colliding galaxies.
But it's not just Hubble's cutting-edge optics that are responsible for these stunning photographs. Behind each image is the hard work of a team of researchers in Baltimore, who balance art and astronomy to capture out-of-this-world pictures that further our knowledge of outer space.
OK, that was very clever
You win a cookie :-)
The yellow galaxies in this image belong to the cluster itself, however, the red and blue distorted streaks are background galaxies gravitationally lensed by the cluster. Some of the lensed galaxies are over 13 billion light years (4000 megaparsec) distant. The lensing zone itself is 2 million light years (0.60 megaparsec) across.
The original troll perhaps?
Re #6: I can see my house. Neat!
Funny you should say that...
Astronomers using NASA's Hubble Space Telescope took advantage of a giant cosmic magnifying glass to create one of the sharpest and most detailed maps of dark matter in the universe. Dark matter is an invisible and unknown substance that makes up the bulk of the universe's mass.
The new dark matter observations may yield new insights into the role of dark energy in the universe's early formative years. The result suggests that galaxy clusters may have formed earlier than expected, before the push of dark energy inhibited their growth. A mysterious property of space, dark energy fights against the gravitational pull of dark matter. Dark energy pushes galaxies apart from one another by stretching the space between them, thereby suppressing the formation of giant structures called galaxy clusters. One way astronomers can probe this primeval tug-of-war is through mapping the distribution of dark matter in clusters.
A team led by Dan Coe at NASA's Jet Propulsion Laboratory in Pasadena, Calif., used Hubble's Advanced Camera for Surveys to chart the invisible matter in the massive galaxy cluster Abell 1689, located 2.2 billion light-years away. The cluster's gravity, the majority of which comes from dark matter, acts like a cosmic magnifying glass, bending and amplifying the light from distant galaxies behind it. This effect, called gravitational lensing, produces multiple, warped, and greatly magnified images of those galaxies, like the view in a funhouse mirror. By studying the distorted images, astronomers estimated the amount of dark matter within the cluster. If the cluster's gravity only came from the visible galaxies, the lensing distortions would be much weaker.
They've grown up seeing pictures like this, and they expect to see something like that through the scope, and instead when they look at the Orion Nebula with their naked eye for the first time, their reaction is "But...it's just some green fuzz! Shouldn't it look like the Mutara Nebula in Star Trek II?"
Thanks for putting these on here, I had no idea how and they are so fantastic!
As the title of this thread proclaimed,
Best Art in the Universe.
Perty stuff. :-) Thanks!
Look like my colonoscopy photos taken last week. Gee, didn’t know my insides were so pretty.
IMO everyone should take a week or so and go out to the Hubble site and flip through the images. They're magnificent.
They better not pull Hubble down until they got something better to replace it with. Hubble's given us a mind-boggling amount of knowledge about the solar system and the universe that we can get from no other source.
My UCLA astrophysicist son tells me that new ground-based telescopes will soon outdo Hubble, except in the x-ray band, where the atmosphere is too absorptive. Computational methods can now correct for the distorting effects of the atmosphere in real time. Soon you’ll be able to do Hubble-like photos using larger mirrors that you couldn’t possibly launch into space.
That is amazing but I totally see a face in that picture. Just imagination I know but it’s so clear to me. A man, mouth open.
