NASA spacecraft across the inner solar system captured new views of Comet 3I/ATLAS—the third known interstellar object

Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle that challenges existing theories about the formation of galaxies and black holes in the early Universe. The discovery connects early black holes with the luminous quasars we observe today.

A newly discovered cluster of objects called the “inner kernel” of the Kuiper belt could teach us about the early history of the solar system – including the movement of Neptune

Humans and their ancestors have likely been kissing for a very long time

Researchers tracked thousands of Americans for decades, finding no links between ingesting recommended levels of fluoride and lower cognitive skills

When engineers struggled to make 3D printer nozzles narrow enough for their needs, they turned to nature and found the proboscis of a female mosquito had exactly the properties they needed

Although these findings from JWST are yet to be confirmed, they mark the closest astronomers have come to locating the universe’s most ancient stars

Observations of a merging black hole further supports the Area Theorem of black hole thermodynamics, which states that the event horizon of a black hole produced by two merging black holes must have a surface area no less than the areas of the original two.
