An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light-years. That is equivalent to lining up 140 Milky Way galaxies back-to-back.

Porphyrion’s jets are estimated to contain the total power of trillions of suns and raise the temperature of surrounding gas by a million degrees Celsius. This means they may have inhibited the formation of not just stars but entire galaxies in the early universe. Their high-speed sprays of magnetized ejecta also could have pierced and filled voids in the cosmic web, the network of matter-rich filaments and matter-sparse cavities that forms the universe’s large-scale structure.

To better assess the impact such jets may have had on the early universe, researchers will need to create a more comprehensive catalog of the structures. The new study surveys just 15 percent of the sky, possibly leaving many more jets yet to be discovered.

The crusade to impose certain religious views (aka “Christians”) on other peoples health care.  Antiscientific and discriminatory.  

Using the Religious Freedom Restoration Act (RFRA) as a weapon to stomp all over your freedom.

This little bugger’s known as ‘the golden tortoise beetle,’ a tiny, metallic North American insect that belongs to the leaf beetle family. We don’t exactly know how these critters change colors, but it’s thought to be an optical illusion caused by hydrating and dehydrating nanosized grooves in their shells. This type of rapid color-changing is extremely rare in insects. They tend to do it most readily when mating or when disturbed by a predator. It’s likely changing colors here because it’s agitated, meaning this person’s got one grumpy golden beetle on their hands. [Source] [Learn More]

Today's my dad's birthday, so I made a drawing for him. I drew a portrait of a scythian hunter from the Altai Mountains, based on a photo he found in his favorite science journal (the italian version of @scientific_american ) many years ago. #drawing #ink #traditionalart #traditionaldrawing #ink #hunter #traditionalartist #blackandwhite #scythia #shythian #scythians #scientific_american #scientificamerican #artistoninstagram #art #drawing https://www.instagram.com/p/BzRGS7bCtxY/?igshid=1rwcqq3wa8slu
