The Arms of M106
Typical in grand spiral galaxies, dark dust lanes, youthful blue star clusters, and pinkish star forming regions trace spiral arms that converge on the bright nucleus of older yellowish stars. But this detailed composite reveals hints of two anomalous arms that don’t align with the more familiar tracers. Seen here in red hues, sweeping filaments of glowing hydrogen gas seem to rise from the central region of M106, evidence of energetic jets of material blasting into the galaxy’s disk. The jets are likely powered by matter falling into a massive central black hole.

The Great Meteor Procession of 1913
One hundred years ago today the Great Meteor Procession of 1913 occurred, a sky event described by some as “magnificent” and “entrancing” and which left people feeling “spellbound” and “privileged”. Because one had to be in a right location, outside, and under clear skies, only about 1,000 people noted seeing the procession. Lucky sky gazers — particularly those near Toronto, Canada — had their eyes drawn to an amazing train of bright meteors streaming across the sky, in groups, over the course of a few minutes.(…)
Pictured above is a digital scan of a halftone hand-tinted image by the artist Gustav Hahn who was fortunate enough to witness the event first hand. Although nothing quite like the Great Meteor Procession of 1913 has been reported since, numerous bright fireballs — themselves pretty spectacular — have since been recorded, some even on video.
