7:30 AM | Terra dei Fuochi: bisogna migliorare la conoscenza scientifica
Il miglioramento della conoscenza scientifica e la sua rilevanza traslazionale nelle questioni ambiente-salute rappresenta l'unico strumento valido per comprendere le criticità delle aree contaminate e per attuare misure di prevenzione

4:00 AM | Materia scura: dallo spazio all’LHC
Mentre gli scienziati del programma Dark Energy Survey (DES) hanno pubblicato la prima di una serie di mappe della distribuzione di materia scura nello spazio cosmico, ci si interroga sulle modalità con cui il Large Hadron Collider (LHC) potrà essere in grado di rivelare le eventuali particelle che la compongono. L’occhio di DES Le mappe di DES, … Continue reading Materia scura: dallo spazio all’LHC →

12:56 AM | Throwback Thursday: Is the Universe fine-tuned for us? (Synopsis)
“There is a voice inside of you That whispers all day long, ‘I feel this is right for me, I know that this is wrong.’” -Shel Silverstein It’s pretty obvious that the Universe exists in such a way that it admits the possibility of intelligent life arising. After all, we’re here, we’re intelligent life, and…

9:12 PM | The Fertile Crescent of Space Exploration
The new image of Ceres that NASA released today is doubly thrilling. It unveils more of the landscape of this mysterious in-betweener world--an object classified both as a giant asteroid and as a dwarf planet, a type of object never before observed up close. But it also taps into the unique significance of the crescent shape, both to our culture and to our science. The crescent is one of the most recognizable icons in astronomy. It is the signature element of the oldest known representati

8:42 PM | NASA Probe Welcomes a New Dawn at Ceres
As this stunning series of observations from NASA's Dawn mission shows, sunlight is returning to Ceres' surface, allowing the spacecraft its first view of the tiny planet after being hidden in its shadow for more than a month.

6:17 PM | Giant Galaxies Die from the Inside Out | ESO
Astronomers have shown for the first time how star formation in “dead” galaxies sputtered out billions of years ago. ESO’s Very Large Telescope and the NASA/ESA Hubble Space Telescope have revealed that three billion years after the Big Bang, these galaxies still made stars on their outskirts, but no longer in their interiors. The quenching […]

6:15 PM | ALMA Reveals Intense Magnetic Field Close to Supermassive Black Hole | ESO
The Atacama Large Millimeter/submillimeter Array (ALMA) has revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black hole via ALMA Reveals Intense Magnetic Field Close to Supermassive Black Hole | ESO.

5:49 PM | Enceladus Spreads Ghostly Ice Tendrils Around Saturn
A ghostly apparition has long been known to follow Saturn moon Enceladus in its orbit around the gas giant. But until now, scientists have had a hard time tracking its source.

5:40 PM | Ep. 373: Becquerel Experiment (Radiation)
Antoine Henri Becquerel discovered radioactivity completely by accident when he exposed a chunk of uranium to a photographic plate. This opened up a whole new field of research to uncover the source of the mysterious energy.

4:15 PM | Could Next-Gen Hubble Telescope Seek Out Alien Life?
The iconic Hubble Space Telescope turns 25 this month, and getting the ball rolling on a life-hunting successor instrument would be a fitting birthday present, one prominent researcher argues.

2:38 PM | White Dwarf May Have Shredded Passing Planet
The destruction of a planet may sound like the stuff of science fiction, but a team of astronomers has found evidence that this may have happened in an ancient cluster of stars at the edge of the Milky Way galaxy. Using several telescopes, including NASA's Chandra X-ray Observatory, researchers have found evidence that a white dwarf star - the dense core of a star like the Sun that has run out of nuclear fuel - may have ripped apart a planet as it came too close. How could a white dwarf star, […]

11:00 AM | To Mars
Why is Elon Musk so hell-bent on going to Mars? There are two answers to this. One is the actual answer. The other isn't exactly wrong—it’s technically correct—but it’s incidental. And it turns out that’s not even really the right question. Bear with me a moment. You need a little background. I’ve been interested in SpaceX for a while now. Years ago, when Musk announced he was going to launch the first privately-funded liquid fuel rocket into orbit, I figured […]

8:00 AM | There Goes the Sun
During a total eclipse of the sun, the landscape darkens. But you knew that. What you might not know—what I didn’t know, anyway, when I observed a total solar eclipse on August 11, 1999—is that the experience comes with a lot of other sensory overload. I found myself thinking about that total eclipse while reading about the one […]

7:00 AM | L’Universo è in espansione accelerata? Non così tanto
Uno studio potrebbe contrastare il modello, comunemente accettato, di un tasso di espansione dell’Universo in continuo aumento. Questo grazie alla scoperta di due diverse popolazioni di supernovae

7:00 AM | Sol 958: Officially 10k!
by Ryan Anderson The Sol 957 drive went well, and the rover has officially driven 10 kilometers! (Last week I announced that we had reached 10k, but that was 10k measured by how many times the wheels have spun, not how far across the surface of Mars the rover has gone. Now, no matter how you measure it, we’ve gone 10,000 meters!). Unfortunately, we stopped with a ridge in front …

4:00 AM | La nostra ‘finestra’ nell’Universo con gli occhi dei telescopi
Qual è il nostro ruolo nell’Universo? È una delle questioni fondamentali che l’uomo si pone da sempre. Attraverso la storia della nostra civiltà, l’astronomia ha permesso di andare oltre la comprensione di un tale quesito e oggi sia gli strumenti che gli scienziati continuano in questa affascinante ricerca. In questo video, Jason Kalirai dello Space … Continue reading La nostra ‘finestra’ nell’Universo con gli occhi dei telescopi […]

11:59 PM | What the hell are Baryon Acoustic Oscillations? (Synopsis)
“If you think this Universe is bad, you should see some of the others.” -Philip K. Dick When it comes to measuring the expansion history of the Universe, the concept is simple enough: take something you know about an object, like a mass, a size, or a brightness, then measure what the mass, size or brightness appears…

12:50 PM | Arriva Watson Health Cloud, l’archivio globale dei dati relativi alla salute
Tra fitness tracker personali, dispositivi medicali collegati, impiantabili e altri sensori che raccolgono le informazioni in tempo reale, l’individuo medio, nel corso della sua vita, può generare più di un milione di gigabyte di dati relativi alla sua salute (l’equivalente di più di 300 milioni di libri). È tuttavia difficile collegare questi gruppi di informazioni dinamici [...]
