It is a simulation of two spiral black holes that merge together and emit gravitational waves.
This artist illustration shows the unexpected darkening of the star Betelgeuse.
This extremely distant galaxy, which resembles our own Milky Way, appears as a ring of light.

The blue dot in the center of this image marks the approximate location of a supernova event that occurred 140 million light years from Earth, where a white dwarf exploded and created an ultraviolet flash. It was located near the tail of the constellation Draco.
This radar image captured by NASA’s Magellan mission to Venus in 1991 shows a corona, a large circular structure 120 miles in diameter, named the Aine Corona.
When a star’s mass is ejected during a supernova, it expands rapidly. Eventually, it will slow down and form a hot bubble of glowing gas. A white dwarf will emerge from this gas bubble and cross the galaxy.
The afterglow of a short gamma-ray burst detected 10 billion light-years away is shown in a circle. This image was taken by the Gemini-North Telescope.
This image from the Hubble Space Telescope shows NGC 7513, a barred spiral galaxy 60 million light years away. Due to the expansion of the universe, the galaxy appears to be moving away from the Milky Way at an accelerating rate.
This artist’s concept illustration shows what the bright blue variable star looked like in the dwarf galaxy Kinman before it mysteriously vanished.
This is an artist’s illustration of a supermassive black hole and its surrounding gas disc. Inside this disc are two small black holes orbiting each other. Researchers identified an eruption of light believed to originate from one of these binary pairs shortly after they merged into a larger black hole.
This image, taken from a video, shows what happens when two objects of different masses merge and create gravitational waves.
This is an artist’s impression showing the detection of a repetitive rapid radio burst seen in blue, which is in orbit with an astrophysical object seen in pink.
The rapid radio bursts, which cause a sensation by leaving their host galaxy in a bright burst of radio waves, have helped detect “missing matter” in the universe.
A new type of explosion has been discovered in a tiny galaxy 500 million light years from Earth. This type of explosion is called a fast blue optical transient.

This illustration shows the core of a star, known as a white dwarf, driven into orbit around a black hole. During each orbit, the black hole plucks more material from the star and drags it into a disc of glowing material around the black hole. Prior to its encounter with the black hole, the star was a red giant in the later stages of stellar evolution.

This is an artist’s impression of two white dwarfs merging together. While astronomers expected it could cause a supernova, they found an example of two white dwarf stars that survived the merger.

After the stars die, they expel their particles into space, which in turn form new stars. In one case, stardust embedded itself in a meteorite that fell to Earth. This illustration shows that stardust could flow from sources like the Egg Nebula to create the grains recovered from the meteorite, which landed in Australia.
