In addition to gazing at the early universe, Hubble also helped astronomers gauge how much time had passed since the Big Bang. Patel Leiden Universityand the 3D-HST Team This composite image shows examples of galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.
April 25, Servicing Mission 1: By measuring a special kind of pulsing star known as a Cepheid variablethey were able to narrow down the age of the universe from its pre-HST range of 10 to 20 billion years to a more precise When one of Hubble's data-handling units failed, the mission was pushed back to to include a replacement part for that, too.
Hubble also examines individual stars in various stages of their evolution — from the clouds of dust that form infant stars to the corpses of those long since detonated, and those in between. Illustration of Present Milky Way Credit: Also see the news release policy. To reduce Hubble space telescope risk, a nitrogen gas purge was performed before launching the telescope into space.
The astronauts on Mission 4 repaired or replaced several systems and installed two new instruments: Recent Hubble discoveries Here are some additional highlights of Hubble's discoveries for the past five years: Should a shuttle be damaged upon liftoff, there was no safe haven for astronauts to retreat to in case of emergency.
Conception, design and aim[ edit ] Proposals and precursors[ edit ] Astronaut Owen Garriott works next to Skylab's manned solar space observatory, InHermann Oberth —considered a father of modern rocketry, along with Robert H. Participation in this program is open to all categories of organizations, both domestic and foreign, including educational institutions, profit and nonprofit organizations, NASA Centers, and other Government agencies.
Fundamental Physics with HST Over the last three decades the Hubble Space Telescope has played a crucial role in probing key parameters relevant to fundamental physics and cosmology. Some prominent features are clearly visible, including the heavily eroded Arabia Terra in the center of the image and the small southern polar cap.
Optical telescopes typically have mirrors polished to an accuracy of about a tenth of the wavelength of visible lightbut the Space Telescope was to be used for observations from the visible through the ultraviolet shorter wavelengths and was specified to be diffraction limited to take full advantage of the space environment.
February Servicing Mission 4: OAO-1's battery failed after three days, terminating the mission. It took three years before NASA could mount a repair mission. Yet inHubble captured pictures of the planet Fomalhaut b, the first time an extrasolar planet was directly imaged in visible light.
Second, a space-based telescope could observe infrared and ultraviolet light, which are strongly absorbed by the atmosphere. With the completion of the last servicing mission inHubble remains in good health and is pegged to continue operations well past the launch of a successor observatory — the James Webb Space Telescope — in Sifon Leiden ObservatoryR.
Thomas Cornell University ; L. More than just pretty pictures, the dozens of terabytes of data collected has provided insight into the universe, from objects as close as the moon to the most remote galaxies, with incredible photos of supernovas and nebulas in between.
Made fresh observations of the " Pillars of Creation " to see how they changed over time, captured the sharpest view ever of the Andromeda Galaxyperformed the best 3-D view of the deep universeand observed a dark vortex on the planet Neptune.
A proposed precursor 1. Therefore, its mirror needed to be polished to an accuracy of 10 nanometers 0. Windhorst Arizona State University and H. With the completion of the last servicing mission inHubble remains in good health and is pegged to continue operations well past the launch of a successor observatory — the James Webb Space Telescope — in When the comet Shoemaker-Levy crashed into the Jupiter inHubble photographed the fatal collision.
Second, a space-based telescope could observe infrared and ultraviolet light, which are strongly absorbed by the atmosphere.
Mirror polishing continued until May This region is full of star clusters, glowing gas, and thick dark dust. Breathtaking photos and science-changing discoveries from 25 years of exploration.
The Hubble Space Telescope Program resides at the NASA Goddard Space Flight Center, Greenbelt, MD. The creation of material for this website through the years has mostly been linked to the Hubble servicing missions.

View All Usage of ESA/Hubble Images and Videos. Hubble's Universe Unfiltered is a collection of video podcasts. Each episode offers an in-depth explanation of the latest news story or image from the Hubble Space Telescope, presented by. The Large Space Telescope was renamed the Hubble (HST) in honor of Edwin Hubble, an American astronomer who, among other things, determined that the universe extended beyond the borders of.
