Space Fan News #31: The Star That Shouldn't Exist; Diamonds in the Sky

Use it, it's yours! http://facebook.com/SpaceFan

There was a really interesting story from the European Southern Observatory this week along with the Diamond planet story submitted via the facebook page.

Diamond planet???? wanna bet space flight takes a serious jump in technology all of a sudden? LOL.

keeps the edits in - they're funny  great vid

Great video though and very interesting. Thanks for sharing your erudite information.

I always have found it amusing how we humans always want to make sense of untenable information. The galaxy may not even exist, it may just be an amalgam of our collective imagination. I remember when I was a child in the 60s hearing how the universe was 5 billion years old. Now, I have only live 50 years but the universe has aged 10 billion. Why not just get it over and say the Universe is like 60 dectillion years old. Prove it's not. Or maybe one earth year equals 500 million space years.

astronomy blows my mind..how can they know stuff like we believe the pulsar is spinning 10,000 times per second,and this planet is gazillions of miles/light years away but were pretty sure its made of diamond..how the f are they really gonna know any of this--i know,i know mathmatics/physics...makes my head spin..amazing!

@SomedaysDreamersBC diamonds are really common and are only expensive because the industry is controlled by a cartel

[MrPlatonist]

waaa! O.O Solar Jetman (NES) had chrystal planets. now it suddenly feels like it makes sense XD

[ColonyWarrior]

Thats no ordinary star... its a space station.

LOL you messed up the name at 0:13 you said SDSS J102915+272927 but you got i right later on.

I got to say I love your videos :-D keep up the good work

[test123ok]

why does a pulsar speed up when it is fed with more mass ? shouldn't the extra inertia slow it down or is angular momentum somehow involved?

how much of the mass gets siphoned out ? does its diameter increase or does it get more dense?

Naming conventions need to change

@DougieBarclay Neutron starts have an average diameter of 10-15 kilometers, that would be 6 (average radius)*Pi kilometers * 10.000 per second, which is roughly 20.000km/s or 6,6% the speed of light :)
