We estimate the rate of collisional ionization in solid-density aluminium plasmas at temperatures ~30 eV to be several times higher than that predicted by standard semiempirical models.

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

Twenty years ago, the US Congress instructed NASA to find 90 percent of near-Earth asteroids threatening Earth.

Can you explain what the collisional cross-section of a molecule is and the theory behind it? The collisional cross-section of a molecule is a measurement of a molecule in the gaseous phase.

Planet formation is common, with a Jupiter-mass planet in close orbit around at least 5% of all main sequence stars. The systems that are observed are surprisingly diverse and very different from our ...

So Lieberman took him to his lab at Harvard University. He had him run over a flat metal plate that measures the collisional force of a footfall. Lieberman says runners generate a lot of ...

The best example of such a system is the Cartwheel galaxy. The optical image of the gamma-ray emitting collisional ring galaxy system, ‘Kathryn′s Wheel’. (Right): Glowing hydrogen gas ...
