Introduction: Invisible Universe Revealed (02:18)


One of the Boldest experiments ever undertaken, and responsible for countless historic discoveries, the Hubble Space Telescope has changed the way we understand the universe.

Hubble Space Telescope (03:14)

Matt Mountain describes the Hubble Space Telescope. Amber Straughn and Mario Livio speak about the spectacular images that the Hubble produces.

Mother of the Hubble (01:54)

Nancy Roman tells of her start at NASA and her belief in the possibility of the getting a telescope into space.

Atmospheric Distortion (01:19)

Jim Crocker gives an analogy explaining the effect of the atmosphere on the images telescopes can see. Roman gathers a committee to begin work on designing a space telescope.

Edwin Hubble (03:14)

Edwin Hubble searched the heavens for a specific type of star in order to measure the size of the universe. Livio describes some of Hubble's discoveries.

Making the Hubble (03:29)

Roman talks about the salesmanship necessary to convince Congress to fund the Hubble program. Faber talks about the limited view NASA had of the creation of the Hubble Mirror.

Launching the Hubble (03:05)

NASA launches the Hubble Space Telescope into orbit via the Space Shuttle. Astronomers are shocked when the first images from the telescope are out of focus.

Spherical Aberration (03:24)

Sandra Faber explains what went wrong to create the poor images from the HST. A NASA board of inquiry searches for the causes of the problem.

Blue Ribbon Committee (03:51)

Faber and Crocker speak about the committee that was tasked with finding a method to fix the HST. Story Muskgrave talks about training for the mission to fix the Hubble.

Fixing the Telescope (02:43)

Astronauts ride the Space Shuttle into orbit to perform repairs on the HST. Mountain explains the necessity of precision as Kathryn Thornton installs COSTAR.

First Images (02:12)

With the installation of COSTAR, scientists are ecstatic with the high quality images coming from the HST.

Birthplace of Stars (01:56)

Hubble images reveal the stellar crucibles which give birth to stars and solar systems. Straughn explains the findings in a Hubble image of the Orion Nebula.

The Deep Field (02:23)

Mountain explains the idea of the using the Hubble to stare at a blank portion of the sky. Mountain and Livio explain how many stars are in the universe.

The Age of the Universe (07:05)

Saul Perlmutter and Adam Riess lead opposing teams searching for the age of the Universe. Perlmutter and Riess are jointly awarded the Nobel Prize in physics for discovering that the expansion of the universe is accelerating.

Galaxies and Black Holes (02:47)

Faber talks about observing super massive black holes and measuring their speed and mass. Faber's team measure multiple galaxies and found black holes at the center of them all.

Maintenance and Upgrades (05:33)

NASA astronauts encounter unique problems while installing new equipment on the Hubble Space Telescope. Astronauts Mike Massimino and John Grunsfeld speak about the space walks they've performed on the Hubble.

Legacy of the HST (01:39)

Regarded as the most productive scientific instrument in history, the HST has cemented its legacy in the annals of science.

25 years ago, NASA launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. This single telescope has helped astronomers pinpoint the age of the universe, revealed the birthplace of stars, and uncovered black holes lurking at the heart of galaxies. In honor of its anniversary, NOVA tells the remarkable story that forever changed our understanding of the cosmos and our place in it.
