Half of all light in the universe is in millimeter-wavelength light between the far infrared and radio waves. ALMA can detect this light, which is emitted by cool objects and distant objects. It's possible thanks to the telescope's location at 16,400 feet in the driest desert on Earth, and because of the incredible precision of its 66 antennas.

The Thirty-Meter Telescope to be constructed on Mauna Kea in Hawaii will surpass even theHubble Space Telescope in some ways, giving scientists a new view of some of the oldest stars and galaxies in the universe, as well as planets orbiting nearby stars.
This instrument will be so powerful it will bring into view galaxies forming at the edge of the observable universe, near the beginning of time (i.e. near zero time)>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The James Webb Space Telescope
Replacement for Hubble Space Telescope
The project is working to a 2018 launch date.
The James Webb Space Telescope (sometimes called JWST) is a large, infrared-optimized space telescope.
Webb's instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.
Webb will have a large mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court.
Webb will find the first galaxies that formed in the early Universe,

DRONE VIDEO: THE GIGANTIC NEW TELESCOPE CHINA'S BUILDING TO HUNT ALIENS
MAKING FAST PROGRESS
By Sarah Fecht
Posted October 13, 2015
Bigger is better when it comes to radio telescopes--and China is building the biggest."">
China began constructing the world's largest and most sensitive radio telescope this past summer. New drone footage released by China Central Television shows they are making rapid progress. The telescope is expected to be ready by September of next year.
When it's finished, the Five-hundred-meter-Aperture Spherical radio Telescope (FAST) dish's diameter will surpass the current record holder, the Arecibo Observatory in Puerto Rico, by 200 meters. It will be able to detect radio signals from planets a billion miles away, potentially widening the search for alien life. It could also detect new exoplanets, pulsars, and galaxies, while helping to shed light on the evolution of the cosmos.
The telescope dish will be supported and moved around by a system of poles and cables, which can be seen in the video. Read more about how it will work.

ReplyDeleteNASA’s latest image of the James Webb Space Telescope is beautiful

Now that spring has arrived, NASA has released a new image of the largest and most expensive space telescope in history — and, in our eyes, it’s the most glorious yet.After two decades of construction, the agency announced the completion of the James Webb Space Telescope last November, following the first important pretest to measure its primary mirror. Over the next few months, the telescope went through a series of grueling trials that shook, rattled, and froze the state-of-the-art machine, subjecting it to conditions it will have to face in outer space. Now, with the final gold-coated segment of its 21-foot-wide mirror array in place, the telescope sprawls like an enormous sunflower.
Scheduled to launch in October 2018, the Webb telescope will be the most powerful telescope in existence, built to capture infrared light from the first galaxies of the ancient universe.To launch the satellite, the Webb telescope’s sunshield will be folded a dozen times before being packed into a bullet-shaped capsule. Once 930,000 miles distant from Earth (at the Earth-Sun L2 Lagrange point), the array will unravel in a glorious, sky-gazing display.“The groundbreaking sunshield design will assist in providing the imaging of the formation of stars and galaxies more than 13.5 billion years ago,” Webb sunshield manager Jim Flynn said in a statement last November. “The delivery of this final flight sunshield membrane is a significant milestone as we prepare for 2018 launch.”At $8.7 billion in construction and operating costs, the Webb telescope is more than four time as expensive as its predecessor, the Hubble Space Telescope, and 100 times more powerful. However, where the Hubble was within reach of astronauts who could spacewalk to the telescope if anything were to wrong, the Webb will be too far into space for an easy mission. For that reason, it’s imperative that everything work as planned before the Webb telescope is sent on its journey.
