Há 4 dias · telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
23 de mai. de 2024 · The two key telescope properties are: 1.45 × 0.5 m primary mirror for each telescope; 1.0 × 0.5 m focal plane array on which light from both telescopes is projected. This in turn consists of 106 CCDs of 4500 × 1966 pixels each, for a total of 937.8 megapixels (commonly depicted as a gigapixel-class imaging device).

It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets.
23 de mai. de 2024 · Planck. (spacecraft) Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013. It was an ambitious project that aimed to map the anisotropies of the cosmic microwave background (CMB) at microwave and infrared frequencies, with high sensitivity and angular resolution.
6 de mai. de 2024 · The James Webb Space Telescope is the largest, most powerful space telescope ever built. It will allow scientists to look at what our universe was like about 200 million years after the Big Bang. The telescope will be able to capture images of some of the first galaxies ever formed.
21 de mai. de 2024 · Hubble Space Telescope, the first sophisticated optical observatory placed into Earth’s orbit. Some of its many triumphs included the Hubble Deep Field, a photograph of about 1,500 galaxies revealing galactic evolution, and the discoveries of Hydra and Nix, small moons orbiting the dwarf planet Pluto.
Há 3 dias · Erik Gregersen. James Webb Space Telescope (JWST), satellite observatory designed as the successor to the Hubble Space Telescope (HST) and launched by an Ariane 5 rocket in 2021. The JWST has a mirror 6.5 meters (21.3 feet) in diameter, seven times larger than that of the HST.
