The largest comet ever discovered became active much farther from the sun than previously believed, according to a new study. Only one other active comet has been observed farther from the sun; however, it was much smaller than comet Bernardinelli-Bernstein (BB). BB at 100 km in diameter dwarfs every other known comet by a hefty margin. (Halley’s comet, by comparison, is 15 km in diameter, while 1 km is typical.)

A team of researchers found the solar wind, comprised of charged particles from the Sun largely made of hydrogen ions, created water on the surface of dust grains carried on asteroids that smashed into the Earth during the early days of the Solar System.

About 1000 days after the Mars InSight mission deployed SEIS, the first seismometer on the red planet, researchers are analyzing new seismic data and reporting on instrument responses, using these data to plan for future planetary seismographs.

Astronomers have discovered an unusually massive black hole at the heart of one of the Milky Way’s dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies — the building blocks of the universe — evolve.

After analysing the global plastics value chain, researchers have revealed that the impact of plastics on climate and health is bigger than originally thought due to the increased use of coal for process heat, electricity and as a raw material in production.

Researchers have developed an approach to print skin equivalents. The material may play a future role in facilitating the healing of chronic wounds. The technique is the first of its kind to simulate three layers of skin: the hypodermis, or fatty layer, the dermis, and the epidermis.
