whoa! i totally did a double-take
NASA Astronomy Picture of the Day 2014 July 25
Cosmic Crab Nebula
The Crab Pulsar, a city-sized, magnetized neutron star spinning 30 times a second, lies at the center of this tantalizing wide-field image of the Crab Nebula. A spectacular picture of one of our Milky Way’s supernova remnants, it combines optical survey data with X-ray data from the orbiting Chandra Observatory. The composite was created as part of a celebration of Chandra’s 15 year long exploration of the high energy cosmos.
Like a cosmic dynamo the pulsar powers the X-ray and optical emission from the nebula, accelerating charged particles to extreme energies to produce the jets and rings glowing in X-rays. The innermost ring structure is about a light-year across. With more mass than the Sun and the density of an atomic nucleus, the spinning pulsar is the collapsed core of the massive star that exploded, while the nebula is the expanding remnant of the star’s outer layers. The supernova explosion was witnessed in the year 1054.

If Andromeda were brighter, this is how it would look in our night sky.
They’re all out there, we just can’t see them

Ancient Chinese instrument, the sheng, which originated back in 1,100 BC, and it can perfectly replicate the music in Mario.
It even makes the coin noises.
Why do people wait for new years to change their lives
Stunning photos of tears under a microscope vary by emotion
"The project, called "The Topography of Tears," captures unique moments in human experience, but there’s also a scientific reason why every tear looks so different. There are three different types of tears: basal (lubricating), reflex (responding to stimuli) and psychic (triggered by emotion). Each type of tear contains different organic substances, and the molecular makeup depends on the causative agent. For instance, emotional tears contain the neurotransmitter leucine enkephalin, a natural painkiller that the body releases to mitigate stress."
First time watching fireworks:
First time being dunked into water that’s way too cold:
First time getting caught in a bubble shower:
First time driving through a dark tunnel:
First time chatting with a puppet:
First time finding a new recipe in a cooking magazine:
First time forgetting how spoons work:
First time seeing ice cream:
Whenever I’m feeling sad, I look at this and realise how fucking amazing the world is
