British researchers have created the ‘new black’ of the science world - and it is being dubbed super black.
The material absorbs all but 0.035 per cent of light, a new world record, and is so dark the human eye struggles to discern its shape and dimension, giving the appearance of a black hole.
Named Vantablack, or super black, it also conducts heat seven and half times more effectively than copper, and is ten times stronger than steel.
It is created by Surrey NanoSystems using carbon nanotubes, which are 10,000 thinner than human hair and so miniscule that light cannot get in but can pass into the gaps in between.

A Rose in Space - NGC 2237
This flower-shaped nebula, also known by the less romantic name NGC 2237, is a huge star-forming cloud of dust and gas in our Milky Way galaxy. Estimates of the nebula’s distance vary from 4,500 to 5,000 light-years away.
At the center of the flower is a cluster of young stars called NGC 2244. The most massive stars produce huge amounts of ultraviolet radiation, and blow strong winds that erode away the nearby gas and dust, creating a large, central hole. The radiation also strips electrons from the surrounding hydrogen gas, ionizing it and creating what astronomers call an HII region.

im laughing why is this even buried deep inside windows programming
GUYS GO DO THE THING.
WHY IS THIS EVEN HERE?!
Can’t forget about flourish.mid and town.mid
that was a pleasant surprise
Oh my god what.
at first i thought it was music from an RPG game and I was like what is this even doing in my computer and then i kept listening and i- - -

The Boomerang Nebula
The Hubble Space Telescope has “caught” the Boomerang Nebula in these new images taken with the Advanced Camera for Surveys. This reflecting cloud of dust and gas has two nearly symmetric lobes (or cones) of matter that are being ejected from a central star. Over the last 1,500 years, nearly one and a half times the mass of our Sun has been lost by the central star of the Boomerang Nebula in an ejection process known as a bipolar outflow. The nebula’s name is derived from its symmetric structure as seen from ground-based telescopes. Hubble’s sharp view is able to resolve patterns and ripples in the nebula very close to the central star that are not visible from the ground.
Astronomers are uncertain of the cause of bipolar outflow in this, and many other, young nebulae like the Boomerang. It may be that a disk of slow-moving material is situated around the equator of the star, thereby blocking more rapidly moving ejected material there, and allowing only matter closer to the poles to be ejected. Another consideration may be that magnetic fields are responsible for constraining the material and thus causing the double-lobed shape of the nebula.
Bipolar outflows are seen to occur both from very young stars (“protostars”) that are still in the process of collapsing and forming, and from old stars nearing the ends of their lives that have become bloated red giants. The Boomerang is believed to be the ejected outer layers from an old red giant. Each lobe of the Boomerang Nebula is nearly one light-year in length, making the total length of the nebula half as long as the distance from our Sun to our nearest neighbors- the Alpha Centauri stellar system, located roughly 4 light-years away.
