This new picture of the Cosmic Microwave Background, the oldest light in the Universe, was taken by the Atacama Cosmology Telescope. This covers a swath of the sky 50 times as wide as the Moon, representing a region of space 20 billion light-years across. The light, emitted just 380,000 years after the Big Bang, varies in polarization (represented here by redder or bluer colors). Image credit: ACT Collaboration.

A high-resolution image from the Extreme Ultraviolet Imager (EUI) on Solar Orbiter, taken with the HRIEUV telescope on May 30, 2020. The circle in the lower left corner indicates the size of Earth for scale. The arrow points to one of the ubiquitous features of the solar surface, called ‘campfires’ and revealed for the first time by these images. On May 30, Solar Orbiter was roughly halfway between the Earth and the Sun, meaning that it was closer to the Sun than any other solar telescope has ever been before.

An artist’s impression of a thermonuclear supernova: the material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas; eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across our Milky Way Galaxy.
