Einstein's Cross is an example of gravitational lensing.

Mappa della costellazione

known as UZC J224030.2+032131 — has not one but five different nuclei. In fact, the core of the galaxy is only the faint and diffuse object seen at the centre of the cross-like structure formed by the other four dots, which are images of a distant q...See More

Hubble Discovers Four Images of Same Supernova Split by Cosmic Lens

Astronomers using NASA’s Hubble Space Telescope have spotted for the first time a distant supernova split into four images.

The Cartwheel Galaxy, the result of two galaxies that collided about 700 million years ago. The outside ring is comprised of hot blue stars, formed from waves of density moving outwards following the collision. It's a bit larger than the Milky Way, and is located very far away in the constellation Sculptor. It's about 500 million light years distant, or nearly 3 sextillion miles. different shot.

The picture shows a famous cosmic mirage known as the Einstein Cross, and is a direct visual confirmation of the theory of general relativity. It is one of the best examples of the phenomenon of gravitational lensing — the bending of light by gravity as predicted by Einstein in the early 20th century. In this case, the galaxy’s powerful gravity acts as a lens that bends and amplifies the light from the quasar behind it, producing four images of the distant object.

Behemoth Black Hole Found in an Unlikely Place

Astronomers have uncovered a near-record breaking supermassive black hole, weighing 17 billion suns, in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe.

Sirius A and B.. Sirius B is a first discovered and closest to the Earth white dwarf. It is a small companion of Sirius A, the brightest star in the sky, with which it forms a dual system. Its distance from Earth is 8.6 light years, and its apparent brightness is about magnitude 8.
