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
Check out this picture of Saturn’s north polar vortex from the Cassini spacecraft – nice!! You can see a couple more at the link to the Cassini webpage with the above image plus at the links below. NASA’s Cassini spacecraft … Continue reading →
Did you catch today's eclipse? You probably didn't notice the penumbral lunar eclipse unless you knew it was coming — ut fortunately, skywatchers around the world were clearly ready.

Today is a holiday in the states. The day around here features a nice turkey dinner, which I’ve had and now need to go back to work before I get tired. About the image from NASA: NASA’s Mars rover Curiosity … Continue reading →
This image of a double prominence eruption on the Sun was captured by the SDO and earned its rightful place in the NASA Image of the Day. The result here was the nice aurora that it was too cloudy here … Continue reading →
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 [...]
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 [...]
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 [...]
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 [...]

For years, astronomers have known about the supermassive black hole at the center of our Milky Way galaxy, but these pictures from NASA's NuSTAR telescope show a rare view of the usually sleeping giant gobbling down a cosmic snack.

A few nights ago I was experimenting with polar alignment with my newly purchased copy of Alignmaster after I made some adjustments to my scope to minimize poor backlash. Alignmaster is best used in conjunction with a webcam for accurate alignment, although it can be done visually if no webcam is available. Anyway, after playing [...]
A couple of nights ago I had another go at learning to use my un-modified Canon EOS 600D DSLR to hone my techniques in astrophotography with my C6-SGT scope. Now I’m starting to feel like I’m actually getting somewhere!
Even so there were a few things wrong with trying to get this image…..
For instance both the [...]
