Although the August 21st eclipse happened about 6 weeks ago, I realized it would take me a long time to edit all the photos I took during my trip. I had over 2000 individual shots of the eclipse alone, taking a single (1/4000 s) shot every 10 seconds, at ISO 100, with my telescope coming out at around f/6. I’ve done a lot of time-lapse photography before, so I thought it would be a routine shot, but I was wrong. Eclipses are much tougher to edit in terms of a time-lapse. But first, the end result of my 10 hours...
As the search for planets in the galaxy continues, there are two places to focus on: Distant stars with potential large planets, and nearby stars with potential small planets. If we are able to find Earth-like planets orbiting nearby stars, they will be prime targets for future generations to explore. Astronomers have just announced the discovery of three new planets orbiting a star only 40 light years from Earth. The star is a very small red dwarf, only slightly larger than Jupiter, and even though it’s close to Earth, it can’t be seen with the naked eye or even with a large...
Neutron stars are the most extreme objects in the universe that have been proven to exist. Black holes are very likely, but we’re still not 100% sure about them. A black hole is like a giant squid in the ocean. We’re pretty sure they exist, but nobody has caught one. The neutron star on the other hand is like a blue whale, everybody knows they exist, and they are massive, rare, and beautiful. Of course, once we know something exists, the next logical step is to figure out how it behaves, to characterize and generalize it, and to identify where it’s...
Stars are far apart, especially compared to the everyday distances in human experience. The fastest a human being has ever travelled is just shy of 40 Km/s, and even at that incredible speed it would take 30,000 years to reach the closest star. That is an incredible distance no matter how you slice it. Taking it a step further, most stars in the sky are 20-200 times further away, and that’s just the population of stars we can see. So if we go beyond and talk about galaxies and the distances between them, we are literally talking astronomical quantities. Yet even with...
I think he’s had to upgrade his sleigh for space operations in order to reach the three space station astronauts living 400 Km above the surface of the Earth. Realistically, at 7 Km/s, it may be the fastest anyone has ever moved to celebrate Christmas.
