New NASA Sonifications Listen to the Universe’s Past

A quarter of a century ago, NASA released the “first light” images from the agency’s Chandra X-ray Observatory. This introduction to the world of Chandra’s high-resolution X-ray imaging capabilities included an unprecedented view of Cassiopeia A, the remains of an exploded star located about 11,000 light-years from Earth. Over the years, Chandra’s views of Cassiopeia A have become some of the telescope’s best-known images.

To mark the anniversary of this milestone, new sonifications of three images — including Cassiopeia A (Cas A) — are being released. Sonification is a process that translates astronomical data into sound, similar to how digital data are more routinely turned into images. This translation process preserves the science of the data from its original digital state but provides an alternative pathway to experiencing the data.

Un algodón de azúcar cósmico visto desde Chile

Desde Chile, utilizando el telescopio de Gemini Sur, la mitad austral del Observatorio Internacional Gemini que opera NOIRLab de NSF y AURA, los astrónomos obtuvieron esta imagen que registra las consecuencias de una colisión de galaxias espirales hace mil millones de años. Al centro de esta caótica interacción se encuentran dos agujeros negros supermasivos, el par más cercano a la Tierra que se haya registrado.
