HD Black Holes Probe & Hubble Telescope

Awesome stunning video of Huge Black Holes. Sources from: 1. How the Universe Works, a mini-series that originally seen on the Discovery Channel April 25, 2010 to May 24, 2010. narrated by Mike Rowe. This (edited) small part from episode "Black Holes" (May 2, 2010) directed by Peter Chinn. 2.HubbleCast. For centuries, scientists imagined objects so heavy and dense that their gravity might be strong enough to pull anything in, including light. They would be, quite literally, a black hole in space. But it's only in the past few decades that astronomers have conclusively proved their existence. Today, Hubble lets scientists measure the effects of black holes, make images of their surroundings and glean fascinating insights into the evolution of our cosmos. In science fiction, black holes are often portrayed as some kind of menacing threat to the safety of the whole Universe, like giant vacuum cleaners that somehow suck up all of existence. Now, in this episode, we're going to separate the fiction from the facts and we're going to look at the real science behind black holes and how Hubble has contributed to it. Now, could these objects be supermassive black holes, that is, black holes which are millions or even billions of times more massive than the stellar ones? Or was there perhaps a simpler, less exotic explanation, like giant star clusters? Fortunately, Hubble was on its way, along with a range of other high-tech telescopes. When the space telescope was being planned, the search for supermassive black holes was in fact one of its main objectives.... ... In fact, around the very centers of these galaxies, Hubble discovered rotating discs of gas and dust. When Hubble observed the disc at the center of a nearby galaxy, Messier 87, the astronomers saw that its color was not quite the same on both sides. One side was shifted towards blue and the other towards red, and this told the scientists that it must have been rotating very quickly. This is because the wavelength of light is changed by the motion of an object emitting it. Think about how the pitch of an ambulance siren drops as it drives past you, because the sound waves are more spaced out as the vehicle moves away. Similarly, if an object is moving towards you, the light's wavelength is squashed, making it bluer; if it's moving away, it's stretched, making it redder. This is also known as the Doppler effect. So, by measuring how much the colours had shifted on either side of the disk, astronomers were able to determine its speed of rotation. And it turned out that this disk was spinning at a rate of hundreds of kilometers per second. This in turn allowed astronomers to deduce that, hidden at the very center, there must be some kind of object which was two to three billion times the mass of the Sun - and this was very likely a supermassive black hole. Now, along with a lot of other observations, this was a key piece of evidence that led to the notion that there is a supermassive black hole lurking at the center of most, if not all, giant galaxies, including our own Milky Way. Well, the science of black holes has moved along a lot since then. The mystery now isn't whether they exist, but why they behave in the strange ways they do. For example, Hubble observations have helped to show that the mass of a supermassive black hole is closely related to the mass of its surrounding host galaxy. The bigger the black hole, the bigger the galaxy. So a big area in science just now is trying to find out what's going on here, and why the two are linked. Do black holes regulate the size of galaxies, or do galaxies regulate the size of black holes? Or is something altogether different happening? music: The Last Secret (from Midsummer Century) artist: Jonn Serrie album: Century Seasons "Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research.

It is named after the American astronomer Edwin Hubble. Although not the first space telescope, the Hubble is one of the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy. The HST is a collaboration between NASA and the European Space Agency, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. Space telescopes were proposed as early as 1923. The Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. Hubble's Ultra Deep Field image, for instance, is the most detailed visible-light image ever made of the universe's most distant objects. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe. The Hubble is the only telescope ever designed to be serviced in space by astronauts. There have been five servicing missions, the last occurring in May 2009. Servicing Mission 1 took place in December 1993 when Hubble's imaging flaw was corrected. Servicing missions 2, 3A, and 3B repaired various sub-systems and replaced many of the observing instruments with more modern and capable versions. However, following the 2003 Space Shuttle Columbia accident, the fifth servicing mission was canceled on safety grounds. After spirited public discussion, NASA reconsidered this decision, and administrator Mike Griffin approved one final Hubble servicing mission. STS-125 was launched in May 2009, and installed two new instruments and made numerous repairs. The latest servicing should allow the telescope to function until at least 2014, when its successor, the James Webb Space Telescope (JWST), is due to be launched. The JWST will be far superior to Hubble for many astronomical research programs, but will only observe in infrared, so it will complement (not replace) Hubble's ability to observe in the visible and ultraviolet parts of the spectrum. • http://en.wikipedia.org/wiki/Hubble_Space_Telescope .

Journey to the Edge of the Universe [Full - HD 1080p]

National Geographic presents the first accurate non-stop voyage from Earth to the edge of the Universe using a single, unbroken shot through the use of spectacular CGI (Computer-Generated Imagery) technology. Building on images taken from the Hubble telescope, Journey to the Edge of the Universe explores the science and history behind the distant celestial bodies in the solar system. This spectacular, epic voyage across the cosmos, takes us from the Earth, past the Moon and our neighboring planets, out of our Solar System, to the nearest stars, nebulae and galaxies and beyond -- right to the edge of the Universe itself. When you finish this video, you will walk away from it with an awareness that you never had before, of the unseen astronomically massive universe that we float around on like a spec of dust in the ocean. This video takes you on a journey through the universe as if you are watching a Sci Fi adventure. Yet you constantly have to remind yourself that what you're seeing is really out there.

The Hubble Deep Field: The Most Important Image Ever Taken

Get astronomy tweets! http://twitter.com/DeepAstronomy In 2003, the Hubble Space Telescope took the image of a millenium, an image that shows our place in the universe. Anyone who understands what this image represents, is forever changed by it. How Can the universe be 78 billion LY across? I explain that in this article: http://www.deepastronomy.com/hubble-deep-field.html There is also a link to a science paper on the topic, that paper actually states 96 billion LY. http://arxiv.org/abs/astro-ph/0310233

The Hubble Ultra Deep Field in 3D

http://gplus.to/TonyDarnell http://twitter.com/DeepAstronomy http://facebook.com/SpaceFan I've recently discovered an animation that was rendered using the measured redshift of all 10,000 galaxies in the Hubble Ultra Deep Field image. I've written a short script that leads you through a quick history of both deep field images and this video ends with a fly-through of the Ultra Deep Field. Every galaxy in the image is in its proper distance as viewed from the telescope line of sight. As if this image wasn't amazing enough.
