Gravitational lensing occurs when the gravity of a massive object, like a galaxy, warps the fabric of spacetime, bending the light from a more distant background object.

A light echo is created when a star explodes or erupts, flashing light into surrounding clumps of dust and causing them to shine in an ever-expanding pattern.

Using IRAS and NuSTAR telescopes, scientists identify hundreds of obscured black holes hidden behind gas and dust.

The images let scientists resolve the structure of the clouds of dust and gas from which stars and planets form at a high level of detail in galaxies considered galactic satellites of the Milky Way.

While the rings won't be visible to the naked eye any small backyard telescope should show the rings, which will appear as bright oval-shaped disks.

The images were captured by the James Webb Space Telescope, which was developed to view objects too old, distant, or faint for the Hubble Telescope. 

Gravitational lensing has the practical effect of a magnifying glass, microscope, or binoculars, and enables scientists to observe celestial bodies that would otherwise be too distant to discern.

This method could revolutionize the way we discover extrasolar planets, especially those that are challenging to detect due to their distance, mass, or orientation relative to Earth.

By 2027, a pair of space telescopes will be probing deep space to investigate why the universe's rate of expansion is increasing.

A new theoretical model made by Israeli astrophysicists reveals an excess of massive galaxies, in contrast to previously accepted theories.
