Happy birthday to the Hubble Space Telescope. On April 24, 1990, shuttle mission STS-31 saw Discovery launch the telescope successfully into its planned orbit. After some early trouble with mirrors and some daring fix-it missions, Hubble has turned out to be one of the greatest achievements in the history of science. Call that hyperbole if you like, but the more I’ve learned about the Hubble Space Telescope — through the telescope, I should say — the more I stand in awe. (NASA/HubbleSite/APOD)
The concept explores the use of bio-luminescent bacteria fed with methane and composted material (drawn from the Bio-digester in the same series). Alternatively the cellular light array can be filled with fluorescent proteins that emit different frequencies of light.

This is one of the most gorgeous photos called NGC 6302 or the"Butterfly Nebula." This beauty is about 2,200 light years away from Earth and located right in our own Milky Way. The gasses you see here are travelling at about 1 million km per hour!
You can’t see it right away but there is a dying star right smack in the middle. This star is 5 times the mass of our own Sun and is considered to be one of the hottest stars in our Milky Way. The surface temperature is about a scorching 222,204 C or 400,000 F. Our Sun’s surface temperature is about 5,526 C or 9,980 F, so just imagine the hottest day you’ve experience and multiply that by 40! It’ll give you a tiny bit of perspective.

Not only does Destin have one of the best YouTube channels on this fair planet, but he is also a wizard.
Just kidding, he just has an eye for science in everyday life. In the latest Smarter Every Day, Destin and his two adorable assistants make a helium-filled balloon do something very, very strange inside their accelerating minivan. So strange, in fact, that you might feel like his family car is a secret portal to a land where physics is broken.
Here’s an idea: After Destin shows you the trick, pause the video for a few minutes and see if you can figure out what’s going on. Then, if you don’t understand or agree with his explanation, head on over to Reddit to continue the discussion!
Limacina helicina (Gastropoda - Limacinidae) is a shelled pteropod mollusk. It is a key organism in polar pelagic ecosystems, where it can can account for 50% of total zooplankton abundance.
Pteropods are strictly pelagic mollusks that are highly adapted to life in the open ocean. They are commonly referred to as ‘‘sea butterflies’’ due to their wing-like parapodia, which are evolutionary modifications of the gastropod foot.
