This Hubblecast explores how the NASA/ESA Hubble Space Telescope’s observations differ across different wavelengths of the electromagnetic spectrum, and how these observations will be complemented…
This artist’s impression shows a rocky exoplanet with a wispy, cloudy atmosphere orbiting a red dwarf star. Astronomers have identified a new method that could…
An artist’s impression of the rocky exoplanet Kepler-186f, which is one of the most promising candidates for a planet could potentially be habitable, but how…
The Goddard-developed microshutter array technology has evolved since its initial development in the 1990s for the James Webb Space Telescope. Here are images of its…
