The Brightest Star Cluster in Earth's Sky
Pleiades, the brightest and well-known star cluster in earth's sky, is slowly destroying part of a passing cloud of gas and dust, according to NASA. That and the "spidery" imagery in the photo (do you see it?) lends itself to the spider eating the fly metaphor.
The well known Pleiades star cluster is slowly destroying part of a passing cloud of gas and dust. The Pleiades is the brightest open cluster of stars on Earth's sky and can be seen from almost any northerly location with the unaided eye. The passing young dust cloud is thought to be part of Gould's belt, an unusual ring of young star formation surrounding the Sun in the local Milky Way Galaxy. Over the past 100,000 years, part Gould's belt is by chance moving right through the older Pleiades and is causing a strong reaction between stars and dust. Pressure from the star's light significantly repels the dust in the surrounding blue reflection nebula, with smaller dust particles being repelled more strongly. A short-term result is that parts of the dust cloud have become filamentary and stratified, as seen in the above deep-exposure image.

Firefighters in California are still struggling to contain several wildfires nearly one week after they broke out.
- Hundreds of people are still missing after three wildfires spread across Northern and Southern California last week.
- 48 of the 50 deaths occurred after the Camp Fire blazed through the town of Paradise, north of Sacramento.
- On Tuesday night, a fourth wildfire broke out, though it's mostly contained.
We know the dangers of too little sleep. Now for the other side of the story.
- Western University researchers found that sleeping over eight hours per night results in cognitive decline.
- Oversleepers suffer similar difficulties on certain cognitive tests as those who sleep under seven hours.
- Not all the news is bad: One night of oversleeping results in a cognitive boost.
Protected animals are feared to be headed for the black market.
