Mitogenomics provides new insights into the phylogenetic relationships and evolutionary history of deep-sea sea stars (Asteroidea)

open access: yesScientific Reports, 2022
The deep sea (> 200 m) is considered as the largest and most remote biome, which characterized by low temperatures, low oxygen level, scarce food, constant darkness, and high hydrostatic pressure.

On testing laser ablation processes for asteroid deflection [PDF]

open access: yes, 2011
Asteroids represent both an opportunity and a risk. Their pristine environment captures the early formation of the solar system; while their impact potential could result in the mass extinction of life.

Period-Multiplying Bifurcations in the Gravitational Field of Asteroids

open access: yesAerospace
Periodic orbit families around asteroids serve as potential trajectories for space probes, mining facilities, and deep space stations. Bifurcations of these families provide additional candidate orbits for efficient trajectory design around asteroids ...

Research of resonant motion of Apollo asteroids with inner planets

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We study the resonant motion of Apollo asteroids with inner planets (Venus, Earth, Mars). It is shown that 1760 among 2026 Apollo asteroids move in resonance with one, two or three inner planets.

Neil Gehrels–Swift Observatory’s Ultraviolet/Optical Telescope Observations of Small Bodies in the Solar System

open access: yesUniverse, 2023
The Neil–Gehrels Swift Observatory has added extensively to our understanding of small bodies in our solar system through its capabilities to rapidly respond to short-live events such as outbursts and collisions, through its near-ultraviolet coverage ...
