Deep melancholy surrounding
the asteroid Vesta, may indicate that the message has a complex structure, a
characteristic not of asteroids, and to the planets, according to a new study.
Researchers led by
Debra Butskovski (Debra Buczkowski) Applied Physics Laboratory of Johns Hopkins
University in Laurel, Maryland, noted that grooves that extend to the surface
of Vesta, are no cracks in the form of the letter V, which are usually formed on
the surfaces of asteroids in the result their collision with other space
objects, and so-called grabens - areas of the cortex, which fell on the level
of the rest of the surface tectonic fault lines, so that the form of education
closer to the letter U.
But the formation of the graben is only possible if
Vesta has a clear structure, including the core, mantle and crust, the
researchers say.
While scientists cannot
say with confidence that there have Vesta complex internal structure - they
will need to see firsthand the stronger evidence, such as a crater, divided
trough half. But if the data are confirmed, this would mean that the West is
not a space rock, a tiny planet.
The study will appear
in Saturday's Journal Geophysical Research Letters.
