They are simpler than stars , much simpler than planets , and vastly simpler than human beings . Black holes are what is created when matter is compressed into a very small place . They are General Relativity's most extreme prediction . They are commonly created from the violent deaths of stars many times the size of our sun , usually forming from the collapsed core of a supergiant star after it explodes . At the heart of a black hole is a singularity . An infinitesimal point in space where the pull of gravity is infinitely strong and spacetime infinitely curved . At the singularity , space and time

  • Global Culture, Ravi Shankar, and Robbie Krieger

    Updated: 2012-12-12 11:50:59
    Last week I was at the Texas Donuts Meeting. More of that anon perhaps. San Antonio was a vibrant mix of American and Mexican culture. This I expected. After all, if it wasn’t for a few stubborn rednecks at the Alamo and San Jacinto, Texas would still be in Mexico. Shame about the oil. Anyhoo, [...]

  • Farewell Patrick

    Updated: 2012-12-10 23:13:09
    Just flew back in from Texas to find that Patrick Moore died.  Here is Brian May’s very nice obituary. I am not one of the many astronomers who knew him personally, but I am one of the even larger number who was originally inspired by him. Here is the book in question : Observers Book [...]

  • Revealed: My tattoo

    Updated: 2012-11-12 13:00:09
    Folks, it’s time. And an appropriate time: for my penultimate post here at Discover Magazine, I’ve decided to show you my tattoo. I’ve been meaning to post this for a while, but there were a lot of behind-the-scenes issues getting permissions I won’t bore you with. But by the time I was able to post [...]

  • Astronomy podcast for kids

    Updated: 2012-11-09 19:00:47
    I love it when kids get excited enough about science to go out and do something about it. That’s why I’m digging Jeffrey Tang – who’s 10 – because he created the Astronomy For Kids podcast, where he talks about different astronomical things. The first podcast went up in February 2012 ("The Solar System") and [...]

  • Repost: Carl Sagan Day

    Updated: 2012-11-09 16:30:07
    [Today is Carl Sagan's birthday, celebrated by lovers of science and rationality around the planet. I wrote the following post last year, but I think it's still appropriate (and I updated his age). Happy birthday, Carl. It's a darker cosmos without you, but we still walk with the candle you lit for us.] If Carl [...]

  • Moon bounce

    Updated: 2012-11-09 14:00:23
    Of all the amazing pictures returned from the moon by the Lunar Reconnaissance Orbiter – and I may include the Apollo landing sites among them – I think my favorites are the ones showing boulders that rolled down slopes. Did I say rolled? I mean bounced! [Click to enselenate.] This shot from LRO shows the [...]

  • Getting closer: Super-Earth found in a star’s habitable zone

    Updated: 2012-11-08 13:39:26
    Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is [...]

  • Hope glimmers on the horizon

    This will be a quick postette because I have eleven simultaneous deadlines and I am already late for most of them… I trust most of my readers are smiling because of the good news from the US election. But its even better than you might think : it could be good news if you are [...]

  • Back to work

    Updated: 2012-11-07 19:07:11
    A few people – including my pal Deric Hughes – put together this non-partisan and nicely done video in honor of democracy: If you like it, give it a thumbs-up on YouTube and Like it on FB. And they’re right. As I wrote last night, there is much work to be done. I don’t think [...]
