9:45 PM | Planck vs BICEP2: nessuna traccia di onde gravitazionali primordiali
A dispetto di quanto pubblicato lo scorso mese di Marzo in merito alla presunta scoperta di un segnale rivelato da un esperimento condotto con il South Pole Telescope (SPT) e interpretabile come “evidenza indiretta dell’inflazione cosmica” le cui tracce sarebbero rimaste impresse nella radiazione cosmica di fondo (post), una recente analisi congiunta dei dati di … Continue reading Planck vs BICEP2: nessuna traccia di onde gravitazionali primordiali →

8:12 PM | Northern lights time lapse, September 2014
This is my most successfull attempt in making a northern lights time lapse video so far! This video is from September (22./23.9.2014) last year, when pretty nice northern lights were dancing over the sky of Kuusamo, Finland! Please watch the video and see for yourself! Please leave me a comment about whether you liked the […]

12:30 PM | So, About That Huge Discovery Last Year About the Young Universe...
Well, this is disappointing. A team of astronomers announced last year that they thought they had strong and direct evidence for cosmic inflation in the extremely early Universe. But, after follow-up analysis, it turns out the evidence is far weaker, and it appears inconclusive one way or the other. Bummer. OK, so what’s the scoop? First, here’s the announcement from last year when it was thought that the evidence was really good. The details are there. But here’s a summary: […]

9:30 AM | DARK MALT
In almost a century of progress, particle Dark Matter (DM) remains the single, most powerful physics concept able to explain otherwise anomalous observations on all cosmological scales, from motions of stars in the solar neighbourhood to its imprint on the horizon of the observable Universe. Whereas the gravitational nature of DM is now firmly established, … Continue reading DARK MALT →

9:00 AM | The Last Word
January 26 – 30 In guest writer Leslie Evans Ogden’s essay meditation, an Ontario girl builds a bond with the West Coast rainforest through her trail running. We have come to understand that Craig does nothing in half measures. When he wants to understand the Younger Dryas, naturally he drags a sled onto frozen Lake […]

8:33 AM | The Milky Way and its Stars
Studies of Galactic and stellar structure are entering an era replete with data from large space- and ground-based projects. The combination of large photometric surveys carried out in the last 15 years, extensive photometric-variability databases allowing the inner structure of thousands of stars to be studied, and vast high-resolution spectroscopic surveys probing the detailed chemical … Continue reading The Milky Way and its Stars →

11:26 PM | Ask Ethan #73: The Multiverse and you (Synopsis)
“Go then, there are other worlds than these.” -Stephen King, The Dark Tower Ever since quantum mechanics first came along, we’ve recognized how tenuous our perception of reality is, and how — in many ways — what we perceive is just a very small subset of what’s going on at the quantum level in our…

11:00 PM | Do I Need a Trademark?
Owning a Federal trademark registration provides several distinct advantages, including the ability to file a trademark lawsuit to protect the mark. In order to obtain a trademark, applicants must be able to show current use of the mark in commerce, or their intent to use their mark “in commerce” in the future. What do you … Continue reading →

8:11 PM | Astronomers See a Massive Black Hole Tear a Star Apart
A telescope peers into the blackness of deep space. Suddenly — a brilliant flash of light appears that wasn’t there before. What could it be? A supernova? Two massively dense stars fusing together? Perhaps a gamma ray burst? Five years ago, researchers using the ROTSE IIIb telescope at McDonald Observatory noticed just such an event. But far … Continue reading →

5:00 PM | Oldest Planets Found.
Data from the venerable Kepler mission has uncovered the oldest know planets that we have found to date. Kepler-444 is 11.2 billion years old and has five Earth-sized planets in orbit. The five planets are a little smaller than Earth. Additionally, they are way too close to their sun (about 1/10 the distance, or about 9 … Continue reading →

4:31 PM | The right road to scientific revolution
Change in science is very hard. If you want to make your mark as a scientist, you have to achieve a very careful balance. Your results must be new, but consistent with other established science. Truly revolutionary discoveries — both experimental and theoretical — are very rare, often only recognized as revolutionary over time. Then […]

3:59 PM | Rosetta, the Comet, and the Science of Surprise
There is a cliche you hear all the time when scientists describe their experiments: "We expect the unexpected," or its jokier cousin, "If we knew what we were doing it wouldn't be called research." (That second one is often, but dubiously, attributed to Albert Einstein.) But like many cliches, this one is built on a foundation of truth--as the comet explorations by the Rosetta spacecraft and Philae lander keep reminding us. The latest shocks come from the huge batch of science results rel

3:53 PM | Talking to Pluto is hard! Why it takes so long to get data back from New Horizons
As I write this post, New Horizons is nearing the end of a weeklong optical navigation campaign. The last optical navigation images in the weeklong series will be taken tomorrow, but it will likely take two weeks or more for all the data to get to Earth. Two weeks! Why does it take so long?

2:44 PM | BICEP2, è davvero polvere galattica!
Tanto si è detto e scritto in merito ai risultati di BICEP2 (post1; post2; post3; post4; post5) poichè l’incertezza maggiore è derivata dal fatto che essi sono stati ottenuti ad una sola frequenza (150 GHz), rendendo così impossibile determinare lo spettro del segnale. Oggi, però, un sito francese sulla missione Planck (la cui pagina sembra sia … Continue reading BICEP2, è davvero polvere galattica! →
