In 2019, the group spotted structures called spherules in rock cores. These small bead-like structures are left over from impact ejecta—material that is melted and blasted skyward in a split ...

Given enough ejecta, these areas could possibly become clouded with dust. In fact, there are reports of such dust patches naturally occurring near the L4 and L5 points.

Ejecta refers to any material that's "ejected" from a crater as a result of some impact. In this case, the ejecta are pieces of Mars shot out from the giant, main crater cavity formed due to the ...

Ejecta from the DART-produced active asteroid Dimorphos. Nature, 2023; DOI: 10.1038/s41586-023-05811-4 ...

They discovered 50 spherules they thought to be interstellar material. They brought the tiny pieces to Harvard, along with tubes of volcanic ash from the site.

Astrobiologists should examine space dust and other exoplanetary debris to search for the existence of life beyond Earth, a new study suggests.

NASA scientists have encountered puzzling spherules in the past. As far back as 2004, the Mars Opportunity rover, during its expedition in the Meridiani Planum, spotted what's come to be known as ...
