Analysing the charred remains of plants can confirm the locations of asteroid strikes in the distant past, new research shows.
Based on estimates of crater-producing asteroid strikes in the last 11,650 years (known as the Holocene), only about 30% of impact sites have been located.
Until now, there has been no way to distinguish between normal land structures and very small asteroid

This month NASA's DART spacecraft will collide with the smaller of the two Didymos asteroids in deep space, attempting to shift its orbit in what will be humankind's first test of the 'kinetic impactor' planetary defence technique. Meanwhile, down on the ground, ESA's follow-on mission to Didymos has reached its own crucial milestone.

NASA's Juno spacecraft observed the complex colors and structure of Jupiter's clouds as it completed its 43rd close flyby of the giant planet on July 5, 2022.
Citizen scientist Bjorn Jonsson created these two images using raw data from the JunoCam instrument aboard the spacecraft. At the time the raw image was taken, Juno was about 3,300 miles (5,300 kilometers) above Jupiter's cloud tops,

For the first time, astronomers have used NASA's James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable.
The image, as seen through four different light filters, shows how Webb's powerful infrared gaze can easily capture worlds beyond our solar system, pointing the way

Japanese and U.S. physicists have used atoms about 3 billion times colder than interstellar space to open a portal to an unexplored realm of quantum magnetism. "Unless an alien civilization is doing experiments like these right now, anytime this experiment is running at Kyoto University it is making the coldest fermions in the universe," said Rice University's Kaden Hazzard, corresponding theory
