Some of my favorite parts of “Apollo 11″ were these little (way too short) snippets so I thought I’d gif some of them :)

Spaghettification

Spaghettification

Otherwise known as Tidal Disruption Events

Stars die in various ways, and at what point you consider death too could be argued. For example, when a star like our sun runs out of hydrogen fuel, we say it no longer is on the main sequence, it begins to collapse but will quickly reach the pressure needed to fuse the helium that had built up over the 10 billion odd years of fusing hydrogen. A 2nd life then occurs, as the now bloated star enters its red giant stage and for another billion years (maybe), fuses the helium. Eventually it runs out, and the collapse begins again, this time however the pressure inside won't kick off any fusion, it will crush down on the core, shed it's outer atmosphere as a planetary nebula and leave behind a white dwarf.

Spaghettification

A white dwarf is classified as a degenerate star, it shines, although none are visible with the naked eye from Earth, many can be seen with average telescopes. The brightest of which happens to be Sirius B, which orbits the brightest star in our sky, Sirius A, that has an apparent magnitude of +8.5.

The star Sirius B though has halted fusing, it's a massive ball of Oxygen and Carbon at temperatures at the surface of 25,000'c (compared to 5,500'c on our Sun) and emits a lot of radiation, so in some ways it's still active even if all the processes that made it a living star haven't. The White dwarf will continue to burn but slowly lose it's energy. No white dwarf has yet reached it, but eventually they stop emitting and become a black dwarf, but the time it would take is longer than the universe has currently existed.

Other stars die slightly more dramatically, larger mass stars go supernova when the inevitable collapse occurs, but even they leave behind something, be it a neutron star or for the real large ones, a black hole.

Spaghettification

And this brings us back to our tidal disruption events, as many large stars are in binary relationships with other stars, and their collapse into a black hole can have a profound impact on them.

A star that gets too close to a black hole won't just be pulled in, rather, it will slowly be ripped apart long before the remains of that star enter the black hole, causing a mass of radiation to be ejected as it does so.

Spaghettification

As the star approaches the gravity of the black hole, the differential between the gravity on one side and the gravity on the other side, tears the star apart, stripping it of matter that then forms spaghetti like stings that are funnelled toward the black hole.

Until recently, all of this was theoretical, but a recent team of astronomers have for the first time detected the spaghetti wrapped around a black hole like a yarn of wool.

I AGREE WITH YA!

People who call mike Collins “the forgotten astronaut” ....who the fuck are you? Maybe you forgot him?? Everyone who gives a fuck remembered him and loved him.
