PokerStars: why does the hubble or ptolemy tournament continue after the last 72/9000 or 56/7000 people already have their ticket? You don’t get (more) points or anything, do you?
@AnteSavant:
It is a sattelite, to the weekly round.
And even if it’s not a sattelite, i still would like to know why. Because there seems no gain.
because a free roll isn’t a satellite. they have it setup to end when one person is left, like all free rolls are.

Hubble 3D
Through the power of IMAX® 3D, Hubble 3D will enable movie-goers to journey through distant galaxies to explore the grandeur and mysteries of our celestial surroundings, and accompany space-walking astronauts as they attempt the most difficult and important tasks in NASAs history. The film will offer an inspiring and unique look into the Hubble Space Telescopes legacy and highlight its profound impact on the way we view the universe and ourselves. Hubble 3D is an IMAX and Warner Bros. Pictures production, in cooperation with National Aeronautics and Space Administration (NASA). The film reunites the Space Station 3D filmmaking team, led by Producer/Director Toni Myers. Hubble 3D will blast off exclusively to IMAX and IMAX 3D theatres on March 19th, 2010.

How to determine Hubble’s constant from redshift?
If you observed the redshifts of galaxies at a given distance to be twice as large as they are now, then you would determine a value for Hubble’s constant that is:
a) twice as large as its current value.
b) equal to its current value.
c) half its current value.
I thought the answer was half its current value but it came back as wrong? Is it twice as large as its current value??
Thanks!
(a) twice as large as its current value
Hubble’s law is v= H d. So if H is twice as big, then so is the velocity v, and therefore the redshift, for a given distance d.
Hubble 3D Trailer/Commercial
Trailer for the upcoming movie Hubble 3DHubble Views Saturn’s Northern/Southern Lights [HD]
In January and March 2009, Hubble took advantage of a rare opportunity to record Saturn when its rings are edge-on, resulting in a unique movie featuring both of the giant planet’s poles. Saturn is only in this position every 15 years and this favourable orientation has allowed a sustained study of Saturn’s almost symmetric northern and southern lights. At the same time Saturn was approaching its equinox so both poles were equally illuminated by the Sun’s rays.
These recent observations have allowed researchers to monitor the behaviour of both Saturn’s poles in the same shot over a sustained period of time and to study the planet’s northern and southern aurorae simultaneously. Given the rarity of such an event, this new footage will likely be the last and best equinox movie that Hubble captures of our planetary neighbour. Besides the double aurora show, the movie also features an added bonus, as some of Saturn’s moons, or satellites, are seen passing the disc of their parent planet.

How is the space station in an "unreachable orbit" for the Atlantis space shuttle currently repairing hubble?
All the news articles are saying that space shuttle Endeavor is on standby to rescue folks from Atlantis should something go wrong. They specifically say this is necessary because the International Space Station is in an "unreachable orbit". I’m curious as to what this means. What physics would prevent a space vehicle such as Atlantis from moving from Hubble’s orbit to the ISS should it wish to?
amount of fuel available – they only have enough fuel to reach the orbit desired, make adjustments necessary to reach the Hubble, and then to return to earth.
The space station would require fuel to get to a different orbit, stop the shuttle, and then chase down the space station – much more required than to just return to earth.
Hubblecast 05: Hubble finds ring of dark matter
An international team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a ghostly ring of dark matter formed long ago during a colossal collision between two galaxy clusters. This is the first time that dark matter has been found with a distribution that differs substantially from the distribution of ordinary matter.

Hubble’s Successor: The James Webb Space Telescope
Science@ESA (Episode 4): Following The Redshift (Part 2) – Hubble’s Successor: The James Webb Space Telescope.
In this fourth episode of the Science@ESA vodcast series Rebecca Barnes will identify some of the key discoveries achieved with the famous Hubble Space Telescope, look at the concept of redshift, and meet a new telescope that will be used to uncover the early Universe.

Named in 2002 in honour of NASA’s administrator during the Apollo programme, the James Webb Space Telescope (JWST) mission is a collaborative project between the National Aeronautics and Space Administration, the European Space Agency and the Canadian Space Agency.
JWST will address many of the outstanding issues of modern astronomy related to the ‘Early Universe’ and is expected to yield scientific breakthroughs as did its predecessor, the Hubble Space Telescope. JWST will be a general-purpose observatory with a suite of astronomical infrared-sensitive instruments.
Compared to existing or planned observatories, JWST will have the unique advantage of combining superb image quality throughout a wide wavelength range, a wide field of view and unparalleled photon sensitivity due to its 6.5-metre diameter telescope primary mirror.

The James Webb Space Telescope (JWST) is a planned infrared space observatory, the partial successor to the aging Hubble Space Telescope. The JWST will not be a complete successor, because it will not be sensitive to all of the light wavelengths that Hubble can see.
The main scientific goal is to observe the most distant objects in the universe, those beyond the reach of either ground based instruments or the Hubble. The JWST project is a NASA-led international collaboration with contributors in fifteen nations, the European Space Agency (ESA) and the Canadian Space Agency (CSA).
Originally called the Next Generation Space Telescope (NGST), it was renamed in 2002 after NASA’s second administrator, James E. Webb (1906-1992). Webb had headed NASA from the beginning of the Kennedy administration through the Johnson administration (1961-68), thus overseeing all the manned launches in the Mercury through Gemini programs, until just before the first manned Apollo flight.
Current plans call for the telescope to be launched on an Ariane 5 rocket in June 2014, on a five-year mission (10 year goal). The JWST will reside in solar orbit near the Sun-Earth L2 point, which is on a line passing from the Sun to the Earth, but about 1.5 million km farther away from the Sun than is the Earth.
This position, which moves around the Sun in exact orbital synchrony with the Earth, will allow JWST to shield itself from infrared from both Sun and Earth, by using a single radiation shield positioned between the telescope and the Sun-Earth direction.
