Although, it wasn’t until 1949 that cosmic X-rays were discovered. So it seems some things still do take time. Learn more about the history of X-ray Astronomy here: http://chandra.harvard.edu/xray_astro/history.html

Six Galaxy Clusters: Dark Matter is Darker Than Once Thought
http://chandra.si.edu/photo/2015/dark/

These galaxy clusters are part of a large study using Chandra and Hubble that sets new limits on how dark matter—the mysterious substance that makes up most of the matter in the Universe—interacts with itself. The hot gas that envelopes the clusters glows brightly in X-rays detected by Chandra (pink). When combined with Hubble’s visible light data, astronomers can map where the stars and hot gas are after the collision, as well as the inferred distribution of dark matter (blue) through the effect of gravitational lensing.

LIGHT: Beyond the Bulb – Image of the Day!
Earth
This image of Earth, known as the "Blue Marble" from NASA, is so familiar that most of us consider it to be our planetary self-portrait. But did you know that the Earth does not actually emit any of the light in this famous image? Rather, all of the light seen here is reflected from the Sun.
