Far-infrared astronomy. Far infrared image of the Andromeda galaxy from the Herschel Space Observatory. Far-infrared astronomy is the branch of astronomy and astrophysics that deals with objects visible in far-infrared radiation (extending from 30 μm towards submillimeter wavelengths around 450 μm).

Dec 22, 2023 · NASA’s James Webb Space Telescope has revealed Rho Ophiuchi like never before, showing new features of the star-forming region to astronomers in this stunning 2023 image. Webb builds on the legacy of infrared telescopes like IRAS and Spitzer. NASA, ESA, CSA, STScI, Klaus Pontoppidan (STScI) Clouds of gas and dust in space – like Rho ...
Jul 27, 2021 · Infrared astronomy started seriously in the mid-twentieth century, but a few much earlier landmarks are worth mentioning. In 1800 William Herschel noted that when he explored the energy in the spectrum of sunlight using a thermometer, the maximum response was obtained when the thermometer was just off the edge of the visible light, at the red end of the spectrum.
Jul 20, 2020 · The study of celestial infrared radiation is an essential component of modern astronomy, providing knowledge of the Universe that is impossible to learn in any other way. William Herschel, 1738 - 1822. Credit: Royal Astronomical Society. It all began at the turn of the 19th century, when German-born musician turned English astronomer William ...
Infrared astronomy reveals the secrets of the Universe beyond visible light. A guide to infrared astronomy, why astronomers use infrared to study the Universe and the space telescopes that have paved the way.
Sep 11, 2003 · In our own Solar System, cold objects such as comets and asteroids reveal most of their characteristics to us in infrared light. Dark cloud seen by ISO, one of ESA's ghosts. Other things of great interest to astronomy are hidden within or behind vast clouds of gas and dust. These clouds hide stars and planets in early stages of formation and ...
Infrared astronomy originated in the early 19th century with the work of William Herschel ( see Herschel family), who discovered infrared radiation while studying sunlight. The first systematic infrared observations of other stars were made in the 1920s; modern techniques, such as the use of interference filters for ground-based telescopes ...
