There is something strange in samples from asteroid Bennu.

“A view of eight sample trays containing the final material from asteroid Bennu. The dust and rocks were poured into the trays from the top plate of the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) head. 51.2 grams were collected from this pour, bringing the final mass of asteroid sample to 121.6 grams.

Reseachers. Made a lot of work. With the samples that OSIRIS REx brought from Asteroid Bennu. 

“Their results show that the distribution of organic matter and minerals is uneven. Instead of being mixed uniformly, the material forms three recurring types of organic–mineral regions. One region is dominated by aliphatic organic compounds, another contains abundant carbonate minerals, and a third is rich in nitrogen-containing organic compounds.”(ScitechDaily, NASA Just Found Something Strange Inside Asteroid Bennu Sample)

“Evidence of Water Shaping Bennu’s Chemistry. This uneven, nanoscale structure indicates that water did not affect Bennu in a single Uniform way. Instead, water interacted differently in separate areas, producing a patchwork of chemical environments across the asteroid.”(ScitechDaily, NASA Just Found Something Strange Inside Asteroid Bennu Sample)

Could Bennu have been covered in water somewhere in its youth? That is possible if Bennu was part of a planet or an ice asteroid. There were planets in the young solar system that no longer exist. Asteroid impacts turn those young planets into asteroids. 

Reseachers found marks of the liquid water effect in samples from asteroid Bennu. There are two ways in which those markings could form. The first one is that maybe Bennu impacted with water ice. And the impact formed liquid water on that asteroid. The second, and far more interesting, is that maybe Bennu was part of an ancient planet or icy asteroid. Then, some cosmic disaster caused that ancient planet to turn into dust. And maybe. Bennu is the remnant of the planet that was destroyed a long time ago. Those marks are interesting in both cases.
