Significant progress in Big Bang cosmology have been made since the late 1990s as a result of advances in telescope technology as well as the analysis of data from satellites such as COBE, the Hubble Space Telescope and WMAP.

Several space observatories did the same, including the Hubble Space Telescope, the ROSAT X-ray observing satellite, and significantly the Galileo spacecraft, then on its way to a rendezvous with Jupiter scheduled for 1995.

* 1993 – Space Shuttle program: STS-61 – NASA launches the Space Shuttle Endeavour on a mission to repair the Hubble Space Telescope.

Hubble Space Telescope and MOST have also found or confirmed a few planets.

At a meeting of the Royal Astronomical Society in Britain, a team from University of Queensland described 40 unknown " dwarf " galaxies in this constellation ; follow-up observations with the Hubble Space Telescope and the European Southern Observatory's Very Large Telescope revealed that ultra compact dwarfs are much smaller than previously known dwarf galaxies, about across.

* 1997 – Space Shuttle Discovery is launched on a mission to service the Hubble Space Telescope.

Beginning in the 1990s, the Hubble Space Telescope yielded improved observations.

Reflection nebula IRAS 10082-5647 taken by Hubble Space Telescope.

Most known debris discs around other stars are fairly young, but the two images on the right, taken by the Hubble Space Telescope in January 2006, are old enough ( roughly 300 million years ) to have settled into stable configurations.

* 2005 – A second photo from the Hubble Space Telescope confirms that Pluto has two additional moons: Nix and Hydra.

This image spans about two light-years and was taken by the orbiting Hubble Space Telescope in 1999.

The final result will be a musical “ history of the universe ", from the Big Bang onwards through galaxy and star formation, up until modern times, including images from the Hubble Space Telescope and rhythms derived from the cosmic background radiation, supernovae, quasars, and many other astrophysical phenomena.

The companion star was resolved by the Hubble Space Telescope in 1995, when it was 70 astronomical units from the primary ; results were announced in 1997.

* 2001 – A hydrogen atmosphere is discovered on the extrasolar planet Osiris by the Hubble Space Telescope, the first atmosphere detected on an extrasolar planet.

Shortly before his death, Mount Palomar's giant reflector Hale Telescope was completed, and Hubble was the first astronomer to use it.

Bush, the launch of the Hubble Telescope, the savings and loan crisis, the election of Bill Clinton and the 1990s economic boom, the longest recorded expansion of GDP in the history of the United States.

The Hubble Space Telescope has a 2. 4 m ( 7 ft 10 in ) primary mirror. The correctly ground backup primary mirror built by Eastman Kodak for the Hubble space telescope ( the mirror was never coated with a reflective surface, hence its Honeycomb mirror | honeycomb support structure can be seen ).

Hubble also became a member of the Kappa Sigma Fraternity ( and in 1948 was named the Kappa Sigma " Man of the Year ").

Hubble was also a dutiful son, who despite his intense interest in astronomy since boyhood, surrendered to his father ’ s request to study law, first at the University of Chicago and later at Oxford, though he managed to take a few math and science courses.

Hubble also served in the U. S. Army at the Aberdeen Proving Ground during World War II.

Wilson, Hubble identified Cepheid variables ( a kind of star ; see also standard candle ) in several spiral nebulae, including the Andromeda Nebula and Triangulum.

Hubble also devised the most commonly used system for classifying galaxies, grouping them according to their appearance in photographic images.

Discovery also flew the Hubble Space Telescope into orbit.

The second and third Hubble service missions were also conducted by Discovery.

Giacconi also applied his expertise to other fields of astronomy, becoming the first director of the Space Telescope Science Institute, the science operations center for the Hubble Space Telescope.

She was also the Principal Investigator the Nuker Team, which used the Hubble Space Telescope to search for supermassive black holes at the centers of galaxies.

It would also see the introduction of space based telescopes, such as the Hubble Space Telescope.

* Eagle Nebula ( also known as M16 ), an astronomical object the subject of a famous Hubble Space Telescope picture

Gold and Bondi also stated that the issues with time scale that had plagued other cosmological theories – such as the discrepancy between the age of the universe as calculated by Hubble and dating of radioactive decay in terrestrial rocks – were absent for the Steady State theory.

Delta Cephei is also of particular importance as a calibrator of the Cepheid period-luminosity relation since its distance is among the most precisely established for a Cepheid, thanks in part to its membership in a star cluster and the availability of precise Hubble Space Telescope / Hipparcos parallaxes.

Elliptical galaxies are ( together with lenticular galaxies ) also called " early-type " galaxies ( ETG ), due to their location in the Hubble sequence, and are found to be less common in the early Universe.

The museum also holds the backup mirror for the Hubble which, unlike the one that was launched, was ground to the correct shape.

He was also the first to derive what is now known as the Hubble's law and made the first estimation of what is now called the Hubble constant which he published in 1927, two years before Hubble's article.

Another record-holder for most distant object is a galaxy observed through and located beyond Abell 2218, also with a light travel distance of approximately 13 billion light years from Earth, with observations from the Hubble telescope indicating a redshift between 6. 6 and 7. 1, and observations from Keck telescopes indicating a redshift towards the upper end of this range, around 7.

Unique to universes described by the FLRW metric, a de Sitter universe has a Hubble Law which is not only consistent through all space, but also through all time ( since the deceleration parameter is equal to ), thus satisfying the perfect cosmological principle that assumes isotropy and homogeneity throughout space and time.

A spacewalk was also performed during the mission to evaluate tools and techniques for the STS-61 Hubble Space Telescope servicing mission later that year.

At UCSD she also helped develop the faint object spectrograph in 1990 for the Hubble Space Telescope.

While administrator, he also approved the Hubble Space Telescope program.

The mission also featured a test of a procedure that was later used during the second Hubble Space Telescope servicing mission to raise the telescope ’ s altitude without damaging the satellite ’ s solar arrays.
