5:00 AM | Siamo vicini alla scoperta della vita extraterrestre?
Che cosa cercano gli scienziati quando vanno alla ricerca di vita aliena? Molto! La ricerca della vita extraterrestre richiede l’aiuto di astronomi, scienziati planetari, chimici, genetisti, per citarne alcuni. La domanda è: stiamo forse guardano nel posto sbagliato? Può la vita svilupparsi in altri modi che non abbiamo mai immaginato? In questo video, che fa … Continue reading Siamo vicini alla scoperta della vita extraterrestre? →

4:37 AM | You Could Name a Crater on the Planet Mercury
The team of scientists and educators behind the Messenger spacecraft orbiting the planet Mercury is giving the public the chance to nominate artists, writers, or composers whose names deserve to be on one of five craters on the hot little planet closest to the Sun. There have been a number of publicity campaigns recently that deal with naming things, but this one is the real thing. By international agreement, the naming of worlds and features in space is done by a special committee of […]

4:00 AM | NGC 3227, l’emissione di radiazione multipla del buco nero centrale
Grazie ad una serie di osservazioni nella banda dei raggi-X riguardanti il buco nero supermassiccio nella galassia NGC 3227, Hirofumi Noda del RIKEN Nishina Center for Accelerator-Based Science e colleghi sono stati in grado di rivelare vari processi multipli che sono responsabili delle emissioni di radiazione. I risultati di questo studio sono pubblicati su Astrophysical … Continue reading NGC 3227, l’emissione di radiazione multipla del buco nero centrale →

2:41 AM | Long-lived lightning clusters in hotspots worldwide
Most lightning hits as a short-lived luminosity, a flickering flash in the pan. Other lightning lingers 10 to 100 times as long. It can simmer the sap of an entire tree and spark a dangerous forest fire. Now, researchers at the University of Alabama in Huntsville have identified hotspots worldwide where long-lived lightning clusters occur.

12:38 AM | The Big Bang for Children (Synopsis)
“To begin, begin.” -William Wordsworth Is the Big Bang the greatest scientific achievement of the 20th century? I — along with many others — would argue that it is. It’s something that even young children are curious about! Perhaps it’s in our nature to wonder about where we come from? Yet despite the fact that it’s been…

11:25 PM | Scientists use satellites to monitor volcano risks
A NASA team utilized satellite data to create a map of past volcanic deposits and modeled the risk to nearby towns. They found one town on a potential lava flow path and a second town at risk for mud flows. The results were presented at Monday’s poster session at the American Geophysical Union’s Fall Meeting. The group’s methodology using satellite images can serve as a template for remotely assessing volcano risk, according to the researchers.

11:15 PM | Researchers keep an eye on walrus ice preferences
To walruses, ice means life. It’s their home base, their mating ground, and their transportation. As climate change threatens the extent of ocean ice, a new study takes a first step at determining how changing ice conditions are influencing walrus dynamics.

10:07 PM | Like A Bad Penny: Methane on Mars
With the announcement of Curiosity's detection of methane on Mars, Nicholas Heavens gives us a guide to the history of methane detection on Mars, a discussion of its scientific significance, and a few things to consider when hearing about and asking about the detection.

10:02 PM | Scientists use drones to monitor surf zone
When ocean scientists visit the beach they pack more than sunscreen and a towel – they pack drones. Researchers show in a new study that drones can be used to cheaply and accurately monitor the movement of water in the surf zone in the Gulf of Mexico. The drones provide a new way of documenting the movement of plant and animal plankton, sediments and pollutants, including spilled oil, near the shore.

6:33 PM | Scientists trying to create “exoplanet zoo”
Scientists are working to simulate and catalogue the properties of Earth-like planets to create an “exoplanet zoo,”—a collection of worlds with similar compositions but different levels of habitability. That’s the goal of a new modeling approach presented by Cayman Unterborn during a poster session Monday morning at the American Geophysical Union’s Fall Meeting in San Francisco.

5:24 PM | Meteor Not?
So in my post about the Geminid meteor shower yesterday, I said that I didn't catch a single Geminid in my photos, and that's true. But going over them carefully, I happened to see something a bit weird, and I'm not sure what to make of it. I took many shots of Orion, since it was perfectly placed over a tree, and any meteors going across it would make for a great photograph. I kept the exposures to 20-30 seconds, since the sky background was pretty bright, and I didn't want the stars to trail […]

12:30 PM | 50 Shades of 67/P
That picture shown above is, seriously, a full-color photo of the comet 67P/Churyumov-Gerasimenko. It was taken by the Rosetta spacecraft on Aug. 6, 2014, when the probe was still 120 kilometers (75 miles) from the comet (long before the Philae lander was deployed). The OSIRIS camera on board has red, green, and blue filters that allow the camera to mimic what the human eye sees. It’s not exact, but it’s close. And what you see is … gray. Which means the comet really is just […]
