Initial designs for the telescope, then named the Next Generation Space Telescope, began in 1996. Two concept studies were commissioned in 1999, for a potential launch in 2007 and a US$1 billion budget. The program was plagued with enormous cost overruns and delays.

2023年1月14日 · There are a number of exciting new observatories coming online in the coming months and years, including the European mission Euclid and NASA's Nancy Grace Roman Space Telescope that will...

2025年1月31日 · The SPHEREx space telescope will shed light on a cosmic phenomenon called inflation. In the first billionth of a trillionth of a trillionth of a second after the big bang, the universe increased in size by a trillion-trillionfold. Called inflation, this nearly instantaneous event took place almost 14 billion years ago, and its effects can be ...

2024年8月22日 · Webb is the premier observatory of the next decade, serving thousands of astronomers worldwide. It studies every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

2023年2月21日 · Mark Clampin, director of NASA’s astrophysics division, says the Habitable Worlds Observatory, the notional name for an $11 billion space telescope that would launch in the 2040s, should be...

2011年4月15日 · NASA engineer Ernie Wright looks on as the first six flight ready James Webb Space Telescope’s primary mirror segments are prepped to begin final cryogenic testing at NASA’s Marshall Space Flight Center. This represents the first six of 18 segments that will form NASA’s James Webb Space Telescope’s primary mirror for space observations.

2024年11月30日 · Scientists working on NASA's Nancy Grace Roman Space Telescope have achieved a significant milestone in assembling the next-generation observatory, which aims to address critical questions...

2024年2月20日 · Not just the next space telescope to be launched — likely NASA’s Nancy Grace Roman telescope in 2027 —but the next Webb-like telescope: a big flagship project for the future,...

2016年7月18日 · Finding and characterizing dozens of Earth-like planets will require a super-stable space telescope whose optical components move or distort no more than a few picometers — a measurement smaller than the size of an atom. It also will require next-generation tools with which to assure that level of stability.

The James Webb Space Telescope (JWST), NASA's next flagship infrared observatory, developed in partnership with ESA and CSA, successfully launched on December 25, 2021. After deploying in space and alignment and calibration of the mirrors and instruments, JWST began science operations in July 2022.
