The heart of this study is a fiber microcavity. Here, one can see a small concave depression in the surface of an optical fiber. The researchers used a microcavity with two concave mirrors, but this image of a single concave microcavity makes it easier to see the fiber mirror setup. Credit: Photo by Carlos...

Vera Rubin’s research forced cosmologists to radically reimagine the cosmos.
In the 1960s and ’70s, Rubin’s observations of stars whirling around within galaxies revealed the gravitational...
Galaxies are the building blocks of the universe, each containing billions of stars, vast clouds of gas and dust, and mysterious dark matter. Among these cosmic structures, the Milky Way holds a special...
Spacecraft and space capsules are some of the most complex and carefully engineered machines ever built by humankind. Comprised of millions of individual parts and components, these vehicles must operate reliably in the...
Satellites are more likely to be at risk from high-speed solar wind than a major geomagnetic storm according to a new UK-US study published this week in the Journal Space Weather.

Competed missions historically cost less and fly more frequently than NASA’s high-profile flagship missions, which generally cost upwards of $2 billion and fly once...
Studying gas in the Universe is no easy task. We often look to ‘non-visible’ wavelengths of the electromagnetic spectrum such as X-rays. The Chandra...
