The bright clutter of individual discoveries can overshadow some fascinating research, from necroplanetology to rogue planets to the intimacy of alphanumeric nomenclature.
Researchers have identified more than 2,000 stars whose past, present, or future vantage points afford a view of Earth passing directly in front of the Sun, a geometry useful for pinpointing planets.
Thanks to last-minute telescope time, researchers pieced together the sequence of events that caused Betelgeuse’s Great Dimming last year.
Proxima Centauri recently let loose a blast of radiation, and ground- and space-based telescopes detected the record-setting event at wavelengths ranging from radio to the ultraviolet.
A planet-hunting satellite’s observations of the nearby system Luhman 16 AB reveal bands of clouds, high-speed jets, and polar vortices.
The gaseous atmospheres of giant planets may evaporate and accrete onto the dense surfaces of white dwarfs, providing astronomers a new way to detect hidden exoplanets.
A small pile of dust grains older than the Sun brings new evidence about the rate at which stars are born in the Milky Way.
A handful of interstellar objects and long-period comets could have scooped up microorganisms from Earth and carried them to worlds around other stars.
Stars with giant planets tend to have a few key elements in abundance. A new algorithm used these patterns to predict hundreds of stars that will likely have exoplanets if we go looking for them.
Scientists searching for life in the universe now have a new target: the once-icy worlds orbiting red giants.
