The asteroid pair (6070) Rheinland and (54827) 2001 NQ8 is investigated and characterized to provide more information about young pairs thought to have formed by rotational fission.

Two supernovae may have occurred at ~50 pc from Earth in the last few Myr. Earth would have seen an increase in TeV–PeV cosmic rays by a factor of a few hundred, returning to normal levels within 10 kyr.

The first data from LAGER, the largest narrowband survey for z ~ 7 galaxies to date, identify 23 Lyα Emitter candidates at z = 6.9. The results support the hypothesis of ionized bubbles in a patchy reionization at z ~ 7.

Spectroscopic and kinematic analysis of 79 nearby M dwarfs in 77 systems reveal 44 young stars, of which 14 are not members of any known moving groups within 100 pc of the Sun.

Evidence is found for the existence of a new family of dark carbonaceous asteroids in the inner asteroid belt; numerical simulations suggest that ~30 of these family members may exist in near-Earth-object space.

By running thousands of N-body dynamical simulations of the TRAPPIST-1 system, scientists find that for solutions stable for millions of years, most of the planets are likely consistent with an Earth-like composition.
