DAT MILKY WAY

The Perseus Cluster, 240 million light-years away, which plays a B, 57 octaves below middle C. Two days ago, it was announced that a mysterious X-ray signal emanating from the galactic cluster could be a sign of a dark matter candidate, a sterile neutrino.

What’s the closest active galaxy to planet Earth? That would be Centaurus A, only 11 million light-years distant. Spanning over 60,000 light-years, the peculiar elliptical galaxy is also known as NGC 5128. Forged in a collision of two otherwise normal galaxies, Centaurus A’s fantastic jumble of young blue star clusters, pinkish star forming regions, and imposing dark dust lanes are seen here in remarkable detail. The colorful galaxy portrait is a composite of image data from space- and ground-based telescopes large and small. Near the galaxy’s center, left over cosmic debris is steadily being consumed by a central black hole with a billion times the mass of the Sun. As in other active galaxies, that process generates the radio, X-ray, and gamma-ray energy radiated by Centaurus A.

Are these snow flakes Or ash?

Who shook the globe And focused our gaze On cadavers of ancient worlds

To remind us in our time We are frozen and alone?
