The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a …

2025年1月17日 · Named in honor of the trailblazing astronomer Edwin Hubble, the Hubble Space Telescope is a large, space-based observatory that has changed our understanding of the cosmos since its launch and deployment by the space shuttle Discovery in 1990.

Hubble is a Cassegrain telescope — a type of reflecting telescope. Light enters the telescope and strikes the large primary, or main, mirror.

2025年1月25日 · Hubble Space Telescope (HST), the first sophisticated optical observatory placed into orbit around Earth. Earth’s atmosphere obscures ground-based astronomers’ view of celestial objects by absorbing or distorting light rays from them.

3 天之前 · In an effort spanning a decade and over 1,000 orbits, Hubble has captured the Andromeda galaxy in stunning detail—revealing everything from young stars to remnants of past galactic collisions. Get your passports and spacesuits ready — you’re going on a …

Hubble Space Telescope – An Overview NASA’s Hubble Space Telescope was the first astronomical observatory to be placed into orbit around Earth with the ability to record images in wavelengths of light spanning from ultraviolet to near-infrared. Launched on April 24, 1990, aboard the Space Shuttle Discovery, Hubble is currently located about

The Hubble Space Telescope is a joint ESA/NASA project and was launched in 1990 by the Space Shuttle mission STS-31 into a low-Earth orbit 569 km above the ground. During its lifetime Hubble has become one of the most important science projects ever.

Hubble is a Cassegrain reflector telescope. Light from celestial objects travels down a tube, is collected by a bowl-like, inwardly curved primary mirror and reflected toward a smaller, dome-shaped, outwardly curved secondary mirror.

Hubble takes sharp pictures of objects in the sky such as planets, stars, and galaxies. Hubble has made more than one million observations. These include detailed pictures of the birth and death of stars, galaxies billions of light years away, and comet pieces crashing into …

2015年4月23日 · Hubble’s telescope is powerful enough to spot the light of a firefly at a distance of some 7,000 miles, and scientists have used these enormous capabilities to unlock many of the secrets of...
