Photo depicting gravitational lensing around galaxy cluster CL0024+1654, located around 5 billion light years from Earth. The multiple blue loops scattered across the image are actually copies of the same distant spiral galaxy.

The Double Helix Nebula, located only 300 light-years from the supermassive black hole at the center of the Milky Way. Incredibly strong and twisted magnetic fields in this region of the galaxy give the nebula its unique geometry.

Dwarf planet Eris situated near Pluto in the Kuiper Belt. Discovered in 2005, its atmosphere freezes into snow when it is farther from the Sun and thaws when it gets closer. Eris is slightly smaller than Pluto, but more massive.

An interacting pair of galaxies known as IC 1623. As the galaxies merge, intense star formation is triggered which is accompanied by bright outbursts of radiation.

Photo of Pluto’s surface taken by the New Horizons spacecraft in 2015. Evidence can be seen for a cryovolcano, a type of volcano that spews out icy water, methane, or ammonia instead of molten rock.

The Red Spider Nebula viewed through the James Webb Space Telescope. It was produced by a star like our Sun reaching the end of its life and shedding its outer layers into space. Radiation from the star’s exposed core continues to ionize clouds of outflowing gas.
