Cosmic simulation reveals how black holes grow and evolve

A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single ...

Energetics of compressive waves in the solar corona

Inelastic scattering off moving or oscillating density fluctuations leads to broadening of radio signals propagating in the solar corona and solar wind. Using an anisotropic density fluctuation model from the kinetic scattering ...

NASA's NEOWISE infrared heritage will live on

NASA's near-Earth-object-hunting mission NEOWISE is nearing its conclusion. But its work will carry on with NASA's next-generation infrared mission: NEO Surveyor.

Moving beyond the 80-year-old solar cell equation

Physicists from Swansea University and Åbo Akademi University have made a significant breakthrough in solar cell technology by developing a new analytical model that improves the understanding and efficiency of thin-film ...

July's night sky notes: A hero, a crown, and possibly a nova

High in the summer sky, the constellation Hercules acts as a centerpiece for late-night stargazers. At the center of Hercules is the "Keystone," a near-perfect square shape between the bright stars Vega and Arcturus that ...
