The universe is a really, REALLY hostile place to be on (as far as we know) the only planet hosting intelligent life.

Obviously, he is experiencing the tidal stresses of a not inconsiderable amount of egoboo… but he handles it very gracefully. Made me laugh several times, and shudder once.

I need an answer to a question that has been bugging this non scientist for years. Can Neil deGrasse Tyson, or any other astrophysicist, explain to me how a distant galaxy looks to the naked eye compared to a distant sun? I mean, how can you tell which you are looking at without a strong telescope?
Please answer. This question is driving me crazy. Thank you.

Gary Reich:
I feel no shame in admitting I have absolutely no idea if you CAN tell the difference unless you really REALLY know what you’re looking for by way of relative position in the sky to other known objects and so on.
I’m sure someone, somewhere, out there can tell you the answer to this. Please, if you do find out, share it with the rest of us.
Great question!

In response to your question about how to tell the difference between types of celestial bodies with the naked eye; you can’t. Galaxies were not even known to exist *to astronomers* until 1923 when Edwin Hubble used a newly completed 100 inch telescope at the Mt. Wilson observatory to observe what were thought to be nebulae (nebulas?), or smears of light in the night sky. Some smears did turn out to be nebulas (clouds of gas illuminated by other stars), but some turned out to be ‘new’ galaxies.
Even with that telescope, Hubble only determined that these objects were other galaxies because he found a way to measure the speed at which they were moving away from us, and derived an expression that gave him the distance to those objects, based on their speed. That told him that they were too far away to be a part of the Milky Way – our own galaxy.
Some of my friends who are professional astronomers have eyes that are good enough to see the smearing around the Great Nebula in Orion, but as for distant galaxies, without a scope, their just dots.
Hope this helps,

Sorry, that should ‘…they’re just dots’ not ‘their’. Oh the shame!

Thanks very much Michael Naray, it’s comforting to know even BSc. Hons. make howler typos like the rest of us sometimes.

[...] Neil DeGrasse Tyson: Death by Black Hole. An incredibly interesting and funny interview with astrophysicist Neil DeGrasse Tyson. He talks about the process of dying in a black hole, defines one of my new favourite words, “spaghettification”, and tells the audience about the asteroid that may destroy the Pacific Coast. A fascinating discussion about some terrible things that may happen to the Earth. “Ninety nine percent of all species that ever existed are now extinct. That is not the signature of a planet that is in love with life.” [...]
