A giant squid haunts the depths of Earth's sky.
A mysterious, squid-like apparition, this nebula is very faint, but also very large in planet Earth's sky. In the mosaic image, composed with narrowband data from the 2.5 meter Isaac Newton Telescope, it spans some 2.5 full moons toward the constellation Cepheus. Recently discovered by French astro-imager Nicolas Outters, the remarkable nebula's bipolar shape and emission are consistent with it being a planetary nebula, the gaseous shroud of a dying sun-like star, but its actual distance and origin are unknown. A new investigation suggests Ou4 really lies within the emission region SH2-129 some 2,300 light-years away. Consistent with that scenario, the cosmic squid would represent a spectacular outflow of material driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, this truly giant squid nebula would physically be nearly 50 light-years across.

The rise of anti-scientific thinking and conspiracy is a concerning trend.
- Fifty years later after one of the greatest achievements of mankind, there's a growing number of moon landing deniers. They are part of a larger trend of anti-scientific thinking.
- Climate change, anti-vaccination and other assorted conspiratorial mindsets are a detriment and show a tangible impediment to fostering real progress or societal change.
- All of these separate anti-scientific beliefs share a troubling root of intellectual dishonesty and ignorance.
The history of the Geneva Conventions tells us how the international community draws the line on brutality.
- Henry Dunant's work led to the Red Cross and conventions on treating prisoners humanely.
