Light from Cygnus A: Celebrating astronomy in this International Year of Light, the detailed image reveals spectacular active galaxy Cygnus A in light across the electromagnetic spectrum. Incorporating X-ray data extends to either side along the same axis for nearly 300,000 light-years powered by jets of relativistic particles emanating from the galaxys central supermassive black hole. Hot spots likely mark the ends of the jets impacting surrounding cool, dense material. Confined to yellow hues, optical wavelength data of the galaxy from Hubble and the surrounding field in the Digital Sky Survey complete a remarkable multiwavelength view. via NASA

Cambridge UK (SPX) Feb 19, 2016 Researchers have shown how a bizarrely shaped black hole could cause Einstein’s general theory of relativity, a foundation of modern physics, to break down. However, such an object could only exist in a universe with five or more dimensions. The researchers, from the University of Cambridge and Queen Mary University of London, have successfully simulated a black hole shaped like a very thi Full article

is there a smell comparable to space ? i assume we dont know because we would die if we tried to smell it but thats so cool
yeah if humans tried to smell space just like that, we’d die, no doubt about it
but the smell of space lingers on spacewalk suits, and docking hatches when astronauts open them!
apparently, space itself smells like burning hot metal, or a hot barbeque grill with a slight hint of spent gasoline. The moon, apparently, smells like a gun after its been shot!
The coolest thing about it all is that the smell is actually what are left of dying stars- it’s literally the smell of stardust, and the particles smell like that because they’re so rich in hydrocarbons- something so very essential to life, and speculated by a lot of astronomers and astrobiologists and such to be the very thing life on earth started from!
another neat fact is that no two solar systems smell the same- ours smells like that because our solar system in particular is extremely rich in carbon, and other solar systems and places in the universe will have extremely different smells depending on what elements are most abundant in their system!
