Description
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...

Aunt Larlie has sent Wibbly a present - a long telescope! Wibbly loves the way it can make things look so much closer than they are! First we try looking at Pigley, then we try looking at the trees in the garden and then, that night, we start looking at space! There, in front of our eyes, there are some space pigs dancing in the starry sky! This telescope really is one of the best presents ever! But then a huge comet starts falling towards us, it...

Humans constantly use radio transmission these days, for everything from military communications to garage-door openers. How can scientists determine which signals come from Earth and which come from space? Learn how the 300-foot telescope was built quickly and cheaply. It ended up studying pulsars and hydrogen in distant galaxies, and made the case for dark matter.

Description
At 17 million pounds, and with more than 2,000 surface panels that can be repositioned in real time, this telescope is one of the largest moveable, land-based objects ever built. The dish could contain two side-by-side football fields, but when its panels are brought into focus, the surface has errors no larger than the thickness of a business card. Welcome to this rare insider's view.

Learn how astronomers use very-long-baseline interferometry (VLBI) with telescopes thousands of miles apart to essentially create a radio telescope as big as the Earth. With VLBI, scientists not only look deep into galactic centers, study cosmic radio sources, and weigh black holes, but also more accurately tell time, study plate tectonics, and more - right here on planet Earth.

Description
Visible light, which can be seen with our eyes, comprises a small sliver of the electromagnetic spectrum. The rest of the spectrum, from short wavelength gamma rays to long-wavelength radio waves, requires special instruments to detect. ALMA uses and array of radio telescopes to detect and study radio waves from space. Radio telescopes are typically large parabolic dish antennas used singly or in an array. Radio observatories are preferentially located...

Here, focus on the story of Edwin Hubble's most famous namesake: the Hubble Space Telescope. Among the heroes who helped make this vision a reality were the astrophysicist Lyman Spitzer; Nancy Roman, NASA's first chief of astronomy; and a team of astronomers and telescope builders who helped repair a critical problem post-launch.

Description
Consider the problem of gleaning information from the severely limited number of optical photons originating from astronomical sources. Our eyes can only do it so well, and telescopes have several major advantages: increased light-gathering power, greater sensitivity of telescopic cameras and sensors such as charge-coupled devices (CCDs), and enhanced angular and spectral resolution.

Radio telescopes are so large because radio waves contain such a small amount of energy. For example, the signal from a standard cell phone measured one kilometer away is five million billion times stronger than the radio signals received from a bright quasar. Learn how each of these fascinating instruments is designed to meet a specific scientific goal.

Non-visible wavelengths compose by far the largest part of the electromagnetic spectrum. Even so, many astronomers assumed there was nothing to see in these bands. The invention of radio and X-ray telescopes proved them spectacularly wrong. Examine the challenges of detecting and focusing radio and X-ray light, and the dazzling astronomical phenomena that radiate in these wavelengths.
