A new study from the University of São Paulo in Brazil said some asteroids orbiting Venus “can pose a collisional hazard to ...

Abstract: In dead zones of protoplanetary discs, it is assumed that micrometre-sized particles grow Brownian, sediment to the mid-plane and drift radially inward. When collisional compaction sets in, ...

Twenty years ago, the U.S. Congress instructed NASA to find 90% of near-Earth asteroids threatening Earth. They've made ...

Here we present a large sample of new simulations of the "Early Instability" scenario. We use an N-body integration scheme that accounts for collisional fragmentation, and also perform a large set of ...

Abstract: We study the nonlinear behavior of the low-frequency dust acoustic instability in a collisional dusty plasma by means of particle simulations. The instability arises due to the streaming of ...

( NewsNation) — Venus could be hiding asteroids that would be deadly if they hit Earth, some experts say. A new study ...

The study was led by Valerio Carruba from the University of São Paulo in Brazil. In it, researchers stated that some asteroids could pose a collisional hazard to Earth. There are allegedly many ...

A new study challenges the traditional view that the India-Asia collision and Tibetan Plateau uplift were continuous through the Cenozoic, showing instead that the collision was short-lived in the ...

We use our filters to identify Haumea collisional family members, which are thought to be collisional remnants of a much larger body and are characterized by large fractions of water ice on their ...
