The crowd-sourced physics simulator Test4Theory has simulated its one trillionth (1012) particle collision since its launch just two years ago.
The solar system is crowded with small objects like asteroids and comets. Most have stable orbits which keep them out of harm's way, but a small proportion of them are in orbits that risk them colliding with planets.
The US space agency has narrowed its hunt for an asteroid to capture to three, NASA said Wednesday.
(Phys.org) —It happens to all kinds of flat, disk galaxies – whether they're big, little, isolated or crowded in a cluster. They all grow out of their irregular, clumped appearance and their older stars take on the same ...
The current theory of star formation has a problem: it cannot make big stars.
Hold out your hand: Look closely. If you're outside on a sunny day, you might see dust motes and pollen dance in the air, perhaps landing on your skin, and bright rays of sunlight peek between your fingers. To the naked eye, ...
A year ago, the world's largest particle collider made one of the greatest discoveries in the history of science, identifying what is believed to be the Higgs Boson—the long-sought maker of mass.
