This artist's impression shows the view from the surface of one of the planets in the TRAPPIST-1 system. At least seven planets orbit this ultracool dwarf star 40 light-years from Earth and they are all roughly the...
Simulations of the cosmic web. The filaments connecting structures are shown. Such structures are predicted by numerical simulations of matter distribution in the universe at different times through the age of the universe.

By using NASA's Spitzer Space Telescope, astronomers have found that the varying glow of brown dwarfs over time can be explained by bands of patchy clouds rotating at different speeds.

This cartoon shows how gas falling into distant starburst galaxies ends up in vast turbulent reservoirs of cool gas extending 30 000 light-years from the central regions. ALMA has been used to detect these turbulent reservoirs of...
This image shows the recovered nova of March 11, 1437 and its ejected shell. It was taken with the Carnegie SWOPE 1-meter telescope in Chile using a filter that highlights the hot hydrogen gas of the shell....
Astronomers observed the magnetic field of a galaxy five billion light-years away. The galaxy provides important insight into how magnetism in the universe formed and evolved.

The central region of the Perseus galaxy cluster. The mosaic image is composed of many "tiles" of long-exposure images taken with the 4.2 metre William Herschel Telescope on the island of La Palma. Ultra-diffuse galaxies...
Illustration shows a likely configuration of a gravitational lensing system discovered by OVRO. The 'milli-lens' is located in or near the intervening spiral galaxy. The lens is magnifying blobs of jet material within the active galaxy PKS1413+135, but the...
