12:30 PM | A Supermassive Black Hole’s Fiery and Furious Wind
When you think of black holes, you probably think they are chaotic destroyers of all; wandering through space devouring everything in their path, and once something gets too close, it’s gone forever. That’s a little unfair. Actually, a lot unfair. They only eat stuff that’s nearby, for one thing. And for another, they’re sloppy eaters. Not everything falls straight down their gullet; a lot of it can swirl around the black hole in what’s called an accretion disk. […]

9:00 AM | Dreaming in the Pleistocene
It would have been different if it hadn’t been a cave, if the excavation had been out in the daylight where mystery more easily washes out. The darkness helped, nothing but my headlamp to show the way. Every morning we’d suit up at the cave entrance. A group of scientists descended a ladder one by […]

4:00 AM | LHC, sale la febbre per il Run 2
A qualche settimana dall’inizio delle attività, la comunità scientifica è in trepidante attesa per i nuovi esperimenti del Large Hadron Collider (LHC) che potrebbero cambiare la nostra comprensione dell’Universo. Fisici ed ingegneri stanno effettuando gli ultimi controlli dopo due anni di manutenzione che hanno portato il grande collisore a raddoppiare l’energia di collisione. Tra gli … Continue reading LHC, sale la febbre per il Run 2 →

10:43 PM | Numbers Game (Synopsis)
No one science can stand wholly on its own. For inquiry about the Universe to give a correct, complete picture, it requires that we bring in a whole slew of evidence, often from tangentially related fields. The interplay between three fields in particular — astronomy, physics, and math (not a science, but the tool used…

4:55 PM | Astroquizzical: What happens when Betelgeuse explodes? (Synopsis)
One of the great, catastrophic truths of the Universe is that everything has an expiration date. And this includes every single point of light in the entire sky. The most massive stars — like Betelgeuse (at the upper left) — will die in a spectacular supernova explosion when their final stage of core fuel runs out.…

3:02 PM | Saharan dust feeds Amazon rainforest just enough to replace lost nutrient
The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rainforest is a dense green mass of humid jungle that covers northeast South America. But after strong winds sweep across the Sahara, a tan cloud rises in the air, stretches between the continents, and ties together the desert and the jungle. It’s dust. And lots of it. Scientists have not only used a satellite to measure the volume of dust that makes this […]

12:30 PM | Why Do Some People Refuse to Get Vaccines?
There’s been a lot of discussion in the media (both mainstream as well as social) about vaccinations, spurred because of the current measles outbreak in the U.S. I’m unhappy about the cause, of course, but I welcome the discussion. I’m just sorry it took an outbreak from Disneyland to get this conversation rolling. A lot of people are blaming anti-vaxxers for the outbreak, but the truth is more complicated than that. Certainly Jenny McCarthy, Andrew Wakefield, and the […]

Una serie di simulazioni realizzate da ricercatori del Tokyo Institute of Technology e della Tsinghua University suggeriscono che la probabilità di trovare pianeti di tipo terrestre, in termini di contenuto d’acqua, è più alta in quei sistemi contenenti stelle simili al Sole. L’attuale ricerca di pianeti abitabili è concentrata in particolare sulle cosiddette nane rosse, ossia stelle di tipo … Continue reading Molti più […]
