Astronomy

Astronomy covers an expansive range of scientific research, from the largest of celestial objects – the infamous black hole – to the smallest detectable objects – the subatomic neutrino.

Current research is focused on understanding the chemical composition and topographical formation of celestial objects such as asteroids, as well as discovering and characterizing exoplanets. In addition to this, research is looking at gravitational waves to understand the curvature of spacetime – experimental proof of a long-predicted theory. Astronomy encompasses all realms of science, so it is truly interdisciplinary.

Ultra-High-Sensitivity, Deeply Cooled InGaAs Cameras for Ground-Based Astronomy in the NIR-II / SWIR

Infrared astronomy started about three decades after infrared (IR) radiation was discovered by Sir William Herschel in 1800. Work in the IR range has been an important facet of astronomical investigation since the 1950s and 1960s, when technological advances in IR detectors began being leveraged to augment the success of…Read Full Article

Is There Really Cool Gas in the Middle of the Sun?

Yes, if you ask a team of researchers from University Hawaii, Institute for Astronomy who returned from an expedition to the blistering Sahara desert, where they found an unexpected source of cool gas-in the outer regions of the Sun. The group headed by…Read Full Article
