Archaeologists have uncovered 1,900 stone artifacts in Chiquihuite Cave, a high-altitude site in the Astillero Mountains in northern Mexico. DNA analysis of the plant and animal remains from the sediment packed around the tools dates the human occupation of the site to 25,000-30,000 years ago. These findings challenge the commonly held theory that the Clovis people were the first human inhabitants of the Americas 15,000 years ago. Team members entering...

This image, captured by the SPHERE instrument on ESO’s Very Large Telescope, shows TYC 8998-760-1 accompanied by two giant planets, TYC 8998-760-1b and TYC 8998-760-1c. The two planets are visible as two bright dots in the center (TYC 8998-760-1b) and bottom right (TYC 8998-760-1c) of the frame. Other bright dots, which are background stars, are visible in the image as well. Image credit: ESO / Bohn et al.

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.

This two-panel illustration shows a black hole surrounded by a disk of gas, before and after the disk is partially dispersed. In the left panel, the ball of white light above the black hole is the black hole corona, a collection of ultra-hot gas particles that forms as gas from the disk falls into the black hole. The streak of debris falling toward the disk is what remains of a star that was torn apart by the black hole’s gravity. The right panel shows the black hole after the debris from the star has dispersed some of the gas in the disk, causing the corona to disappear. Image credit: NASA / JPL-Caltech.

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.
