11:11 PM | total solar eclipse - svalbard
did you see the total solar eclipse on march 20th, 2015? my friend geoff sims was up to capture him consistently amazing photos of the events from Svalbard. and one from 35,000 feet, collaboration with Glenn Schneider.i'd like to see a thorough movie of his experiences and eclipse photos.  here's a preview of that possibility.  support their kickstarter if you want to see it to! i missed it unfortunately, but i absolutely have plans to be in the US on August 21st, 2017 ;)

11:30 AM | Snowy Hawaii
Now here’s something you don’t see every day: snow in Hawaii! To be fair, that’s the Mauna Kea volcano on the Big Island, and it tops out at 4,200 meters (13,800 feet). It’s commonly cold up there, of course, but snow is unusual. The picture is part of a much larger shot taken by the Landsat 8 satellite. By coincidence, my friend and astronomer Mike Brown was at the observatory at the summit and took a lovely photo of it from a more terrestrial viewpoint. It’s […]

4:00 AM | Probing the Fundamental Nature of Spacetime with the Renormalization Group
Renormalization group methods are a key element of theoretical particle physics and may also be central for constructing a fundamental theory of gravity, e.g., based on Weinberg’s asymptotic safety conjecture. The aim of this program is to bring together theorists and phenomenologists in order to discuss ideas related to the application of the renormalization group … Continue reading Probing the Fundamental Nature of Spacetime with the Renormalization Group →

5:52 PM | Why Do Some Asteroids Spin Themselves to Dust?
Astronomers Spy Out Active Asteroids In the “Department of Unusual Solar System Activities” today we have a close look at a type of asteroid that may spin so fast that it literally explodes itself as it ejects dust out to space. This comes to us courtesy of the W.M. Keck Observatory in Hawai’i, and a team [...]

5:12 PM | The Mapping of Pluto Begins Today
When New Horizons flies past Pluto in July, we will see a new, alien landscape in stark detail. At that point, we will have a lot to talk about. The only way we can talk about it is if those features, whatever they turn out to be, have names.

4:40 PM | DNews: 'Goldilocks' Earth May Not Be So Special After All
Earth is in what's called the habitable zone. It's far enough from the sun that it doesn't get fried, and close enough that it gets the best of its warmth. We like to think we're special for this, but it turns out we might be pretty run of the mill.

4:38 PM | MAVEN detects aurora and mysterious dust cloud
Volume 2, Issue 3 Press release: NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed two unexpected phenomena in the Martian atmosphere: an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere. The presence of the dust at orbital altitudes from about 93 miles (150 kilometers) to 190 miles (300 […]

4:24 PM | Wreaking Havoc with a Stellar Fly-By
You can't model RW Aurigae as a single star with a disk of material around it, because there is a second star. And you can't model it as a regular old binary system either, because there are interactions between the stars and the asymmetric disk. The authors of today's paper create a comprehensive hydrodynamic model that considers many different observations of RW Aurigae.

4:18 PM | Solar Eclipse Pictures and Video to Make Your Brain Happy
On March 20, 2015, the Moon passed in front of the Sun ... if you were on the right spot on the planet. Or, better, above it! Let's start off with a special treat: From the ground, master astrophotographer Thierry Legault took video of the International Space Station crossing the Sun during the eclipse! Incredible. Legault is really, really good at this sort of thing and traveled to Spain to catch the fraction-of-a-second event.  Most of the U.S. would've been asleep during the eclipse […]

3:29 PM | Ask Ethan #80: Can space expand faster than the speed of light? (Synopsis)
“If everything seems under control, you’re not going fast enough.” -Mario Andretti One of the toughest things to wrap your mind around in the natural world is the idea of special relativity: the faster you move, the closer you get to the speed of light, the more difficult it becomes to increase your speed at…

1:07 PM | Ep. 369: The Fizeau Experiment
Light is tricky stuff, and it took scientists hundreds of years to puzzle out what this stuff is. But they poked and prodded at it with many clever experiments to try to measure its speed, motion and interaction with the rest of the Universe. For example, the Fizeau Experiment, which ran light through moving water […]

12:00 PM | Caccia aperta alle onde gravitazionali
Se da un lato il bosone di Higgs ha rappresentato per molto tempo il “ricercato” numero uno da parte dei fisici delle particelle, motivo per cui il grande collisore adronico LHC è stato costruito, dall’altro la ricerca delle onde gravitazionali costituisce uno degli obiettivi prioritari a cui gli astronomi si stanno dedicando da qualche tempo.  La … Continue reading Caccia aperta alle onde gravitazionali →

11:30 AM | Crash Course Astronomy Episode 10: The Sun
Doubt thou the stars are fire, doubt that the sun doth move. Doubt truth to be a liar, but never doubt I love. —Hamlet, in a letter to Ophelia Of all the stars in the Universe, the one we know best is our own Sun. That’s not to say we understand it completely, of course. But we know it’s not a burning ember, or a god, or a great ball of fire (goodness gracious). It’s a fantastically huge fusion-generating plasma ball, the main source of light, heat, and gravity in the […]
