5:40 PM | NASA's Chandra Observatory Finds Cosmic Showers Halt Galaxy Growth
This galaxy cluster comes from a sample of over 200 that were studied to determine how giant black holes at their centers affect the growth and evolution of their host galaxy, as reported in our latest press release. This study revealed that an unusual form of cosmic precipitation enables a feedback loop of cooling and heating, stifling star formation in the middle of these galaxy clusters. Abell 2597, shown here, is a galaxy cluster located about one billion light years from Earth. This image […]

4:50 PM | Mars Orbiter Mission Methane Sensor for Mars is at work
After several months of near-silence, ISRO's Mars Orbiter Mission has released on Facebook the first data product from its Methane Sensor For Mars. Don't get too excited about methane yet: there is no positive or negative detection. The news here is that the Methane Sensor for Mars is working, systematically gathering data. They also released several new photos of Mars.

2:42 PM | Healthy Google
Sometimes, it’s the little things. I got an email the other day from someone who works with Google, telling me some cool news: They’ve updated their search results about health conditions. They now provide information that’s curated and vetted by doctors, including the Mayo Clinic! That’s fantastic. So, for example, when you Google “measles,” the first couple of results are (as usual) news items, then links to the Centers for Disease Control and Prevention, […]

9:00 AM | The Language of Change
The nature writer Robert Macfarlane is so skilled—so precise, so observant—that he can make an unsuspecting reader long for mudflats. This careful selector of words is also a collector of them: Macfarlane has just published a lovely essay (and a book) about his hoard of “place words,” terms gathered over years of travel in Britain […]

8:00 AM | IL ruolo dei cambiamenti climatici nella guerra in Siria
Tra i fattori che hanno contribuito allo scoppio del conflitto siriano potrebbe esserci anche una forte ondata di siccità, dovuta ai cambiamenti climatici. Lo svela uno studio della Columbia University

4:00 AM | Come ti peso le particelle nell’Universo primordiale
Secondo alcuni modelli l’energia scura, quell’enigmatica componente responsabile dell’espansione accelerata dell’Universo, è un campo scalare che evolve su tempi scala cosmologici. Ciò vuol dire che alcune quantità fondamentali correlate alle forze e alle masse dovevano essere diverse molto tempo fa. Tuttavia, una nuova analisi dello spettro di un quasar molto distante non trova evidenze di … Continue reading Come ti peso le particelle […]

3:16 AM | The professor will be with you shortly…
So… it’s been rather quiet around here. And I’ve been fairly quiet on the internets in general. But I assure you, my life has been anything but quiet these past few months. And now I can finally get into why.…Read more →

2:13 AM | The closest conjunction of the year (Synopsis)
“Since you cannot do good to all, you are to pay special attention to those who, by the accidents of time, or place, or circumstances, are brought into closer connection with you.” -St. Augustine When you look up at the sky, all the twinkling lights — the stars — appear to be fixed. But littered…

11:30 PM | Going to Mars: Reality Versus Reality TV
The harsh reality that is Mars. (Photos by author). How is Mars One like Amway? Last month, the Mars One project announced that its initial candidate pool of 600 candidates had been whittled down to 100. Excitement then swirled around the ‘net and the space community immediately following the announcement, as local media plugged the [...]

8:55 PM | Watch Ceres rotate: A guide to interpreting Dawn's images
NASA held a press briefing on the Dawn mission yesterday, sharing some new images and early interpretations of them. I see lots of things that intrigue me, and I'm looking forward to Dawn investigating them in more detail. I invite you to check out these photos yourself, and offer you some guidance on things to look for.

Six by six arcminute field around the white dwarf WD 1242-105, courtesy SDSS DR9. The WD is the bluish object at centre. This nearby (39 pc) white dwarf has been found to be a binary object which will merge within three quarters of a billion years, but not catastrophically, i.e. it is likely not a […]

6:03 PM | Rosetta Spots its own Fuzzy Comet Shadow and a Halo
During the Rosetta's close flyby of comet Comet 67P/Churyumov-Gerasimenko on Feb. 14, the European spacecraft snapped images of the comet's 'belly' revealing a shadow of itself surrounded by a halo.

5:00 PM | Rosetta Sees Its Shadow on a Comet
I suppose, if you want to be traditional about it, Valentine’s Day is a good time to get as close as you can to the one you love. That may be why the Rosetta space probe dipped to a mere 6 kilometers from the surface of the comet 67P/Churyumov-Gerasimenko on Feb. 14, 2015. When it did, it saw something remarkable: Its own shadow on the surface of the comet! I guess that means six more weeks of winter for 67/P. Of course, when your temperature is -70 C, it’s always winter. A few […]

4:43 PM | Il quark top ‘compie’ 20 anni!
Vent’anni fa, i fisici degli esperimenti CDF e DZero entrambi al Fermilab annunciavano la scoperta di una nuova particella: il quark-top. Con questo risultato monumentale, gli scienziati confermarono l’esistenza dell’ultimo membro del sestetto di quark del modello standard. Dal 9 al 10 Aprile prossimi, la comunità dei fisici delle particelle commemorerà, si fa per dire, l’evento … Continue reading Il quark top ‘compie’ 20 anni! → […]

4:21 PM | Ceres …Nearly There!
It Won’t Be Long Now The above images of dwarf planet Ceres was captured by NASA’s Dawn spacecraft from about 25,000 miles away on Feb 25. Because of Dawn’s position relative to the dwarf plant/asteroid and the Sun, Ceres appears half in shadow. (Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA) Launched in 2007, back when Apple was introducing the […]

12:30 PM | The World, Ceres
On March 6, the Dawn spacecraft will ease into orbit around the largest asteroid in the main belt: Ceres. As it approached Ceres on Feb. 19, Dawn took a series of images creating this amazing animation: Although the resolution is still a bit low—this was taken from about 46,000 kilometers away, with a resolution of about 4 km/pixel—there are some interesting things you can see. For example, the mysterious pair of bright spots stays very bright even as they rotate into darkness, […]
