The National Aeronautics and Space Administration's Hubble Space Telescope (HST) is the first major infrared-optical-ultraviolet telescope to be placed into orbit around Earth. The telescope is named after American astronomer Edwin P. Hubble,...

April 25, 1990 The Hubble Space Telescope (HST) is the most significant advance in astronomy since Italian astronomer Galileo Galilei (1564–1642) perfected the telescope in the seventeenth century. (An astronomer is a scientist who studies...

From the age of the universe to the existence of black holes and the discovery of new galaxies, the Hubble Space Telescope (HST) is providing a multitude of data for astronomers eager to understand the cosmos. While the telescope is providing images...

Hubble Space Telescope Launched April 24, 1990 The Hubble Space Telescope (HST) was named for Edwin P. Hubble, the first astronomer to prove the existence of galaxies beyond Earth’s galaxy, the Milky Way. Launched from the United States space...

The Hubble Space Telescope (HST) is a large Earth-orbiting astronomical telescope designed by the United States National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). Hubble observes the heavens from 380 mi (612 km)...

The Hubble Space Telescope (HST) is a large Earth-orbiting astronomical telescope designed by the U. S. National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). Hubble observes the heavens from 380 miles above Earth,...

the most sophisticated optical observatory ever placed into orbit around Earth. Earth's atmosphere obscures ground-based astronomers' view of celestial objects by absorbing or distorting light rays from them. A telescope stationed in outer space is...

One of the unavoidable problems facing ground-based telescopes if a phenomenon astronomers call seeing: distortions of the image of a celestial object by the passage of its light through Earth's turbulent atmosphere. This the same phenomenon that...

Most sophisticated optical observatory ever placed into orbit around Earth. Because it is above Earth's obscuring atmosphere, it can obtain images much brighter, clearer, and more detailed than ground-based telescopes can. Named for Edwin Hubble, it...

The Hubble Space Telescope (HST) is a telescope in orbit around the Earth, named after astronomer Edwin Hubble. Its position outside the Earth's atmosphere provides significant advantages over ground-based telescopes — images are not blurred by the...
