The Hubble Space Telescope captured this phantasmic red gas cloud named SNR 0519. Astronomers say it is the remnant of a white dwarf star some 150,000 light-years away that exploded as a supernova.
Williams College astronomer Steven Souza told Huffington Post that “light from the supernova explosion itself would have reached us between 400 and 800 years ago, but there is no indication that anyone actually observed it then. The explosion actually happened about 150,000 years ago, but due to the finite speed of light we are only now seeing its ~600-year-old remnant.”

This is Major Tom to Ground Control, I’m stepping through the door
And I’m floating in a most peculiar way
And the stars look very different today
For here am I, sitting in a tin can, far above the world
Planet Earth is blue and there’s nothing I can do.
-“Space Oddity” by David Bowie
The words to the song Space Oddity have been sweeping across the Internet since May 12. But the voice doesn’t belong to the song’s creator, David Bowie, who originally released it in 1969.
Instead, they were sung by Canadian astronaut and International Space Station commander Chris Hadfield, who recorded it and the accompanying video as part of turning over control of the station on May 12. Hadfield was scheduled to return to Earth on May 13 after an inspiring five-month tour aboard the ISS.
The farewell rendition of Bowie’s long popular song might go down as the most epic and thought-provoking transfers of command in human spaceflight history.

Visualizing Meteorites
Add another one to the list of data visualizations that make science engaging and fun.
Data visualization designer Carlo Zapponi has created an alluring website called Bolid.es showing meteorites that have either been found on the ground or seen falling to Earth. The main draw of the site, as seen in the picture above, puts into motion the fraction of heavenly bodies actually witnessed by people or instruments as they crashed through the atmosphere and collided with the planet.
Zapponi has created a timeline that starts with the record of a 470 g meteorite that fell in Nogata, Japan, in the year 861. In total, the animation illustrates 1,045 witnessed meteorite crashes that are on record with The Meteoritical Society of some 34,800 that have been found.
Check out Zapponi’s website at Bolid.es.

Huge Solar Outburst Captured by Fleet of Spacecraft
NASA’s fleet of spacecraft observing the sun have sent back fascinating and beautiful video from the most recent coronal mass ejection, when a massive burst of matter and magnetic fields shoot out from the star into space.
Four spacecraft recorded the eruption in the extreme ultraviolet band of the electromagnetic spectrum over the course of 2.5 hours. The space agency says CMEs typically eject more than one billion tons of particles at a speed faster than one million miles per hour.
