For some reason, the NASA folks did not link to the research paper describing the newfound dark comets.
Allow me to correct that oversight. Here is "Two Distinct Populations of Dark Comets Delineated by Orbits and Sizes":

Today on the #arXiv :
Seligman et al. 2024, "Two Distinct Populations of Dark Comets Delineated by Orbits and Sizes" - arxiv.org/abs/2412.07603
For those unaware:
The "dark comets" are asteroids that have orbits changing in ways that indicate out-gassing, but have no visible dust or gas tails.

Researchers have found additional space objects like ‘Oumuamua, which are known as “dark comets,” as they do not have glowing tails. These objects may have once delivered water, organic chemicals, and other building blocks of life to Earth. In PNAS: https://t.co/yCu4swOGBl https://t.co/aESC0LQrFR

Abstract Synopsis
- The study identifies two types of dark comets based on their orbits and sizes: larger, eccentric outer dark comets and smaller, nearcircular inner dark comets, suggesting they may represent different stages in comet evolution.
- Some inactive near-Earth objects show nongravitational accelerations likely caused by volatiles-driven outgassing, despite showing no visible signs of dust or comae in images.
- This research indicates that these dark comets could be part of a larger, previously undetected population of volatile-rich bodies that contributed essential materials like water and organics to Earth.
