<h5>What do we know about NASA’s James Webb telescope?</h5><p>NASA’s <a target="_blank" rel="noopener noreferrer" href="https://www.newsahoot.com/articles/nasa-releases-first-photo-by-the-james-webb-telescope">James Webb Space Telescope</a> is the largest, most powerful space telescope ever built, orbiting the Sun 1.5 million kilometres away from the Earth. It studies every phase in the history of our universe, from the first luminous glows after the Big Bang to the formation of solar systems and exoplanets and the evolution of our own Solar System. It was launched on December 25, 2021.</p><p>The James Webb Telescope is as tall as a 3-story building! It sees the universe in light that is invisible to human eyes and which we feel as heat, called infrared radiation. The Webb telescope uses its infrared cameras to see through dust clouds in our universe, inside which stars and planets are formed.</p><p>The Webb Telescope’s cameras are sensitive to heat from the Sun. Just like you might wear a hat or glasses to block the Sun from your eyes, the Webb Telescope has a sun shield to protect its instruments and mirrors. The telescope’s sunshield is about the size of a tennis court. It uses giant, gold-coated mirrors to see the universe.</p><figure class="image"><img src="https://firebasestorage.googleapis.com/v0/b/newsahoot.appspot.com/o/spiral-galaxies-captured-by-the-webb-telescope%2FJames.jpg?alt=media&amp;token=d34865d8-63e1-4238-8b60-d13358a1a471"><figcaption>The James Webb Telescope.

The photos were made public on Monday by a team of scientists involved in a project called Physics at High Angular Resolution in Nearby GalaxieS (PHANGS), supported by more than 150 astronomical observatories worldwide.</p><p>The closest of the 19 galaxies is called NGC5068, about 15 million light-years from Earth, and the most distant of them is NGC1365, nearly 60 million light-years from Earth.</p><figure class="image"><img src="https://firebasestorage.googleapis.com/v0/b/newsahoot.appspot.com/o/spiral-galaxies-captured-by-the-webb-telescope%2F19-spiral-galaxies-Webb-January-29-2024.jpg?alt=media&amp;token=f3e3d34c-a660-49a4-8a81-f58be0481d82"><figcaption>The nineteen spiral galaxies.

It is a galaxy where the stars and gas clouds are concentrated mainly in one or more spiral arms. It has a rotating disc with spiral 'arms' that curve out from a dense central region.</p><p>The Milky Way – the galaxy that includes Earth and our solar system – is an example of a spiral galaxy.</p>
