Despite space observatories such as theHubble Space Telescope(HST) andJames Webb Space Telescope(JWST) being closer to the action, ground-based telescopes can achieve greater dimensions and are far less restricted by weight. When telescopes onEarthare built in a good location, with wide sky views...
A large optical telescope we we have in orbit right now is NASA’sHubble Space Telescope, which was launched in in 1990. It has a 2.4-meter (7.9-foot) mirror that, along with other instruments, has allowed it to refine the age of the Cosmos and show that the universe’s expansion is...
Time to power up the largest radio telescope in the world. China’s Five-hundred-metre Aperture Spherical Telescope, or FAST, began spying on outer space on 25 September. FAST will measure radio waves in space, allowing us to study the rotation of galaxies, monitor the behaviour of pulsars...
To simplify matters greatly, we may consider a telescope to be a collector of photons (a funnel that captures and concentrates the light of the stars). The bigger the mouth of the funnel, the more photons it can gather and, therefore, the greater its capacity for capturing light (...

A prototype part of the software system to manage data from the Square Kilometre Array (SKA) telescope has run on the world's second fastest supercomputer in China. The complete system, currently being designed by an international consortium, will process raw observations of distant stars and gala...

discovered recently, but the world’s largest radio telescope, the Square Kilometre Array (SKA), began construction in Australia and South Africa in December 2022 and will soon open its sensitive radio eye on the universe. This suggests that detecting and using the 21-cm forest may soon be ...

In 2016, China's Five-hundred-meter Aperture Spherical radio Telescope—the largest single-aperture radio telescope in the world—gathered its first light. Since then, the telescope has undergone extensive testing and commissioning and officially went on
