哈勃太空望远镜
The faraway galaxy HerS 020941.1+001557 (rolls off the tongue!) appears in this Hubble image as the red arc partially encircling the bright elliptical galaxy at center. Why does it look like that? This is an Einstein ring – an interesting type of gravitational lensing. Gravitational lenses occur when light from a very distant cosmic object bends (or is "lensed") around a massive (or "lensing") cosmic object located between us and the distant lensed galaxy. When the lensed object and the lensing object align, they create an Einstein ring. Uncover more at the link in our bio! Image description: A field full of distant galaxies on a dark background. Most of the galaxies are very small, but there are a few larger galaxies and some stars where detail is visible. In the very center is an elliptical galaxy with a brightly glowing core and a broad disk. A reddish, warped, ring of light, thicker at one side, surrounds its core. A small galaxy intersects the ring as a bright dot. Image credit: ESA/Hubble & NASA, H. Nayyeri, L. Marchetti, J.
