Early in the history of the universe, the Milky Way galaxy collided with a dwarf galaxy, left, which helped form our galaxy's ring and structure as it's known today.
An artist's illustration of a thin disc embedded in a supermassive black hole at the center of spiral galaxy NGC 3147, 130 million light-years away.
Hubble captured this view of a spiral galaxy named NGC 972 that appears to be blooming with new star formation. The orange glow is created as hydrogen gas reacts to the intense light streaming outwards from nearby newborn stars.
This is jellyfish galaxy JO201.
The Eta Carinae star system, located 7,500 light-years from Earth, experienced a great explosion in 1838 and the Hubble Space Telescope is still capturing the aftermath. This new ultraviolet image reveals the warm glowing gas clouds that resemble fireworks.
'Oumuamua, the first observed interstellar visitor to our solar system, is shown in an artist's illustration.
An artist's impression of CSIRO's Australian SKA Pathfinder radio telescope finding a fast radio burst and determining its precise location.
The Whirlpool galaxy has been captured in different light wavelengths. On the left is a visible light image. The next image combines visible and infrared light, while the two on the right show different wavelengths of infrared light.
Electrically charged C60 molecules, in which 60 carbon atoms are arranged in a hollow sphere that resembles a soccer ball, was found by the Hubble Space Telescope in the interstellar medium between star systems.
These are magnified galaxies behind large galaxy clusters. The pink halos reveal the gas surrounding the distant galaxies and its structure. The gravitational lensing effect of the clusters multiplies the images of the galaxies.
This artist's illustration shows a blue quasar at the center of a galaxy.
The NICER detector on the International Space Station recorded 22 months of nighttime X-ray data to create this map of the entire sky.
