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 public relations boon for astronomy.
Composite image showing how the M87 system looked, across the entire electromagnetic spectrum, during the Event Horizon Telescope's April 2017 campaign to take the first image of a black hole. Requiring 19 different facilities on the Earth and in space, this image reveals the enormous scales spanned by the black hole and its forward-pointing jet.
The Habitable Exoplanet Imaging Mission (HabEx) is a concept for a mission to directly image planetary systems around Sun-like stars. [5] [6] HabEx will be sensitive to all types of planets; however its main goal is to directly image Earth-size rocky exoplanets, and characterize their atmospheric content. By measuring the spectra of these ...
Positioning an optical telescope in space eliminates the distortions and limitations that hamper that ground-based optical telescopes (see Astronomical seeing), providing higher resolution images. Optical telescopes are used to look at planets , stars , galaxies , planetary nebulae and protoplanetary disks , amongst many other things.
The Large-aperture Synoptic Survey Telescope (LSST) is a 6.5-m-class optical telescope designed to survey the visible sky every week down to a much fainter level than that reached by existing surveys. It will catalog 90 percent of the near-Earth objects larger than 300 m and assess the threat they pose to life on Earth.
NASA’s Hubble Space Telescope recently captured a breathtaking image of the spiral galaxy NGC 2566. Astronomers use detailed Hubble images to study star clusters and active star-forming regions.
Exoplanets have been discovered using several different methods for collecting or combining direct images to isolate planets from the background light of their star. Non-Redundant Aperture Masking Interferometry is a method of combining the views of multiple telescopes into a single image, while the other methods are algorithms for combining ...
Details of galactic dust and stars captured by telescope offer a picture to astronomers of the early universe Webb telescope’s new image of eerie nearby galaxy reveals what early universe may ...
