Astronomical detectors as a research area focuses on the development, characterization, and optimization of sensor technologies used to register electromagnetic or particle signals from astronomical sources with high sensitivity, dynamic range, and temporal and spatial resolution. It encompasses work on charge-coupled devices (CCDs), complementary metal–oxide–semiconductor (CMOS) imagers, infrared arrays, superconducting devices such as transition-edge sensors and kinetic inductance detectors, as well as photon-counting and polarimetric detectors. Research addresses quantum efficiency, noise sources, readout architectures, calibration strategies, radiation hardness, and cryogenic operation, enabling precise photometry, spectroscopy, astrometry, and time-domain observations across multiple wavelength regimes.
What do you do when the observation you need comes around once a year? Well, preparation is key, but this is the awkward truth about finding another Earth. When a planet crosses the face of its star, a sliver of starlight ...

There's a nice kind of irony buried in this story: One of the most sensitive instruments ever built, capable of measuring distortions smaller than the width of a proton, has been quietly held back by something as mundane ...

When astronomers talk about directly imaging an exoplanet orbiting a faraway star, the analogy they most commonly use is trying to spot a firefly next to a massive searchlight. An Earth-like exoplanet is incredibly dim—usually ...

We've been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it's gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should ...

Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that signal has normally been based on our own current cutting-edge technology. But what if that's the wrong ...

Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on ...

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something ...
