In the case of ‘Cosmos,’ you become the entire universe.
A recent study has shown that while reading a novel one likes, a phenomenon called “grounded cognition” occurs, whereby the left temporal cortex lights up, which is the place where your brain feels physical and movement sensations, thus creating the feeling that the reader is actually in the protagonist’s body.
NGC 772 (also known as Arp 78) is an unbarred spiral galaxy approximately 130 million light-years away in the constellation Aries.

Do pygmy seahorses search for a coral that matches their color, or do they change their color to match the coral?

"If humanity hopes to realize its dreams of exploring the stars, we’re going to need to find ways to recreate life on Earth aboard a spaceship. Simply stockpiling enough vital supplies isn’t going to cut it, which is what led Julian Melchiorri, a student at the Royal College of Art, to create an artificial biological leaf that produces oxygen just like the ones on our home planet do."
YES. Let’s get off this planet, shall we?
"We believe this study has the potential to change the way we think about the event that led to mitochondria," said U.Va. biologist Martin Wu, the study’s lead author. "We are saying that the current theories — all claiming that the relationship between the bacteria and the host cell at the very beginning of the symbiosis was mutually beneficial — are likely wrong.
"Instead, we believe the relationship likely was antagonistic — that the bacteria were parasitic and only later became beneficial to the host cell by switching the direction of the ATP transport."

A massive star plowing through the gas and dust floating in space. Zeta Oph is a bruiser, with 20 times the Sun’s mass. It’s an incredibly luminous star, blasting out light at a rate 80,000 times higher than the Sun! Even at its distance of 400 light years or so, it should be one of the brightest stars in the sky … yet it actually appears relatively dim to the eye.
Tiger Moth - Creatonotos gangis
What you see in this photo is a male of Creatonotos gangis (Arctiidae), a species of Asian moth, showing his expanded pheromone diffuser structures at the tip of the abdomen (called coremata and androconia). The four coremata are reversible, each when inflated may be longer than the abdomen.
Females pheromonally attract males from long distances, however, when the male is close enough to begin his courtship, he inflates his coremata with air or hemolymph to evert externally from the abdomen and fans pheromones of his own towards the female.
This species of moth is found over much of south-east Asia, as well as in Australia.
