For many years the Hubble Space Telescope has collected breathtaking images of the cosmos with remarkable clarity. Now, ground based telescopes are fighting back. They are combining the precision of several instruments and correcting for atmospheric shimmer. This program presents and explains the designs, uses, and outputs of different types of telescopes.

The Atacama large Millimeter/Sub-millimeter Array, or ALMA, is a vast array of radio telescopes and the most powerful observatory of its kind. ALMA is stationed in the Atacama Desert of Chile which is one of the world’s best sites for observational astronomy because of the high altitude, nearly non-existent cloud cover, dry air and lack of light pollution and radio interference due to the small populations. ALMA peers into previously hidden regions of space with unprecedented sharpness and sensitivity.
The world's largest digital camera is currently being assembled at a warehouse in California, and host Dianna Cowern is there for the revealing of the lenses for this camera. These lenses will go on the Large Synoptic Survey Telescope, which will conduct a giant sky survey by taking panorama photos. Part of the "Physics Girl" series.
At first glance, the bone-dry landscape of the Atacama Desert in Chile might seem inhospitable. But, it’s prime real estate for astronomers. This desert is now home to the largest ground-based radio telescope in the world called the Atacama Large Millimeter/submillimeter Array or “ALMA for short. And, it’s allowing astronomers to see the universe like never before. Part of the National Science Foundation Series "Science Nation."
Today's telescopes study the sky across the electromagnetic spectrum. Each part of the spectrum tells scientists different things about the universe, giving them more pieces of the cosmic jigsaw puzzle. The most powerful telescopes on the ground and in space have joined forces over the last decade in a unique observing campaign, known as the Great Observatories Origins Deep Survey, or GOODS, which reaches across the spectrum and deep back into cosmic time.
The Hubble Space Telescope, flawed when launched in 1990 and repaired in 1993, helps scientists study the universe. Highlights Hubble from design, construction, and repair to a range of spectacular images taken from beyond earth's atmosphere.
Discover how the James Webb Space Telescope will help scientists studying the formation of stars. The telescope will provide infrared observations and give astronomers an unprecedented view of stellar birth. Computer models show how a giant cloud of gas and dust collapses to form stars and planets.
In 1990, when the first images from NASA's Hubble Space Telescope were too blurry to use, JPL scientists and engineers went to work to devise a fix. They created a camera with corrective vision to bring Hubble images into sharp focus. Part of the “Crazy Engineering” series.
How far is a star or a galaxy? Scaling and measuring the cosmos is a complex problem. Scientists are integrating mathematical applications and scientific technology to create measurement standards. Distances are so vast they are described in light years, and nearby stars are measured by trigonometry. Farther out, astronomers use standard candle measurement for deep space exploration.
Students explore the outer planets of the solar system. Vivid, colorful images transmitted by exploratory spacecraft serve as the basis of this video tour of Jupiter, Saturn, Uranus, and Neptune. Often referred to as the "gas giants," the unique features of these large and distant planets are described. Jupiter's Giant Red Spot, Saturn's colorful rings, and the fierce storms of Neptune are highlights of the program. Important terminology includes: sun, rotation, revolution, orbit, ellipse, gravity, inertia, telescope, Hubble telescope, exploratory spacecraft, asteroid belt, meteoroid, and comet.
In the conquest of space today, it is robots, not humans, who get the glory. Describes missions that represent the foreseeable future in space exploration: sensor-filled craft and remotely operated devices going where people can't. The program features Deep Impact, a comet-blasting probe; Cassini-Huygens, pioneer of Saturn's moon, Titan; Robonaut, a machine designed to perform human tasks; Ranger, a huge mechanical spider that could conceivably repair the Hubble Space Telescope; the Hubble itself, aging but carrying on; and the planned Webb Space Telescope, Hubble's eventual successor on the vanguard of deep-space science.
Using crisp images and lifelike animations, this program introduces students to the intriguing realm of stars and galaxies. The main characteristics of galaxies and stars are discussed. Special attention is given to the features of stars, including size, temperature, and brightness. The life cycle of a star is also highlighted, as are the tools used by astronomers to study space. Additional concepts and terminology illustrated in the video include: universe, telescope, satellites, constellations, star color, spectrum, gas, light-year, and black hole.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The friends experience a very beautiful phenomenon known as a star cluster. Maqui tells them that it is an accumulation of stars that holds together as a family. They try to watch it with a telescope, but the telescope gets loose from the spaceship and lands in a planet close by. Their plan is to recover it during the night so they are not seen, but soon they discover that the star cluster prevents the sky from getting dark.
The engineers at NASA are studying two new technologies to help image distant Earth-like planets. Coronagraphs are tiny instruments fitted inside telescopes to block light and help scientists study clues as to whether life is present on a planet. Starshades also block light and produce clearer photographs of distant planets. Both of these technologies are used with telescopes and provide scientists with enhanced photographs of space.

With support from the National Science Foundation, astronomers Marc Buie and John Keller are involving citizen scientists from throughout the western United States to participate in the Research and Education Cooperative Occultation Network (RECON). The project has provided telescope equipment and training to 14 small western U.S. communities north and south of Reno, Nevada, where night skies are clear and dark. When RECON students look out at the night sky, they look way out to the Kuiper Belt, a ring of icy debris that litters the Solar System out beyond Neptune. The network is looking to determine the sizes of Kuiper Belt objects as they pass in front of distant stars. Part of the National Science Foundation Series “Science Nation.”
What are stars, and where do they come from? Briefly discusses the life cycle of a star, their colors, and super nova. Includes the Hubble Space Telescope, how stars were used in history, and constellations. Offers a short review.
The invention of the lens goes far beyond the glasses that sit on one’s nose. Galileo used lenses to create the telescope and bring faraway things closer to mankind. At the opposite end of the spectrum, the lens exposed the microscopic world, leading to medical advancements including vaccination, anesthetics, and antibiotics.
Carl Pennypacker at UC Berkeley runs Universe Quest, a summer program supported by the National Science Foundation to engage girls in science exploration. Some of the summer activities include: looking through a world-class telescope, going out to the beach to measure tides, and designing online games.
Learn about the discovery Saturn's largest ring. In 2009, astronomers announced the discovery of an enormous, diffuse ring that starts about 6 million kilometers away from Saturn and extends another 12 million kilometers. The ring is so dark that it had escaped observation until the Spitzer Space Telescope detected its infrared radiation.
Part of the Project-Based Inquiry Science "Earth Science Content Videos" series.
