The millions of asteroids in the Solar System are thought to be the shattered remains of colliding planetesimals, the large rocky bodies that were the building blocks of the planets. New results suggest that most, if not all, of the known asteroids originate from only a few “common ancestors”, i.e., a small number of very large planetesimals. The study, published in Nature Astronomy, was carried out by a team that includes NOAO astronomer Dan Li.
US scientists invited to help develop exemplar Key Science Programs (KSPs) for GMT and TMT. The KSPs are a key element of the US ELT Program to be presented to the 2020 Decadal Survey.
The Mayall telescope’s new, top end ring was recently installed using a 450 ton crane with a 250 foot boom. The top ring will support new optics for the Dark Energy Spectroscopic Instrument (DESI).
