El Estudio de la Energía Oscura (también conocido en inglés como Dark Energy Survey) fue un programa de observación de seis años diseñado para explorar el cosmos con el fin de comprender mejor la energía oscura, un concepto complejo que se desarrolló cuando los científicos se dieron cuenta de que el Universo parecía estar rompiendo sus propias leyes de la física –supuestamente inmutables. Pero, ¿cómo se observa algo que no se ve? ¿Y por qué los científicos están tan convencidos de que realmente hay algo que buscar?
The Dark Energy Survey was a six-year observing program designed to survey the skies in order to better understand dark energy — a complex concept that developed when scientists realized that the Universe seemed to be breaking its own supposedly immutable laws of physics. But how do you observe something that cannot be seen? And why are scientists so convinced that there is really something to search for?

SpinQuest is supported by the DOE Office of Science.

The new findings indicate that small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.
