Fuji X-T2 è la migliore mirrorless mai costruita

Geek   02.03.17  

Può la Fujifilm X-T2 essere la migliore fotocamera in commercio? Un'atipica recensione del gioiello mirrorless della casa giapponese che continua a stupire il mercato della fotografia.

Finally, the Fuji XT2 is actually greater than the sum of its parts. Yes it works great, it's lightweight and affordably priced. More than that however, the XT2 is a true joy to shoot with. It feels great in the hand. The buttons and knobs are placed in intuitively welcome locations. The soft click of the aperture rings on the lenses are comforting. The LCD viewfinder with histogram guarantees that I'll nail each exposure every time. The color and look of the files are fantastic. More than any other camera I own–or have owned–this is the camera I want to shoot with.

Simply put, the XT2 is the best balance of price, weight, performance and usability that I've experienced in my 26 years of professional photography. If you're a lifestyle, wedding, portrait or serious enthusiast photographer, the Fuji XT2 camera will serve you well and without excuse.

Da oltre 50 anni i macachi giapponesi, che vivono tra le montagne del Parco Nazionale Joshinetsu-Kogen, trascorrono il periodo invernale alle terme naturali delle sorgenti calde di Jigokudani a Nagano, diventandone una delle principali attrazioni turistiche e fonte di studio per biologi e sociologi.

Un sistema planetario pronto a ospitare la vita

Geek   22.02.17  

La NASA ha annunciato di aver scoperto sette esopianeti di tipo terrestre che orbitano attorno alla stella nana Trappist-1, tutti candidati a ospitare un'atmosfera e acqua allo stato liquido.

The planets orbit a dwarf star named Trappist-1, about 40 light years, or about 235 trillion miles, from Earth. That is quite close, and by happy accident, the orientation of the orbits of the seven planets allows them to be studied in great detail.

One or more of the exoplanets - planets around stars other than the sun - in this new system could be at the right temperature to be awash in oceans of water, astronomers said, based on the distance of the planets from the dwarf star.

"This is the first time so many planets of this kind are found around the same star," said Michael Gillon, an astronomer at the University of Liege in Belgium and the leader of an international team that has been observing Trappist-1.

Archeologia spaziale

Geek   30.01.17  

Il National Geographic racconta come gli archeologi moderni abbiano iniziato a sfruttare la tecnologia delle rilevazioni satellitari per scoprire e analizzare siti archeologici e riportare alla luce antichi reperti.

Parcak uses remote sensing to see what would bethings hidden to the human eye. "Space archaeology is the study and the use of satellite images for mapping ancient archaeological features and environmental features by looking at different parts of the light spectrum," saidsays Parcak. "We see subtle changes on the Earth's surface caused by what's buried beneath." The satellite imagery records frequencies outside the visible spectrum that the human eye can see: near infrared, middle infrared, thermal infrared, and radar. This imagery reveals features such as buried stone walls, geology, and vegetation changes. Enhanced imagery can help identify buried sites that archaeologists can then explore on the ground.

La luna che increspa gli anelli di Saturno

L'effetto gravitazionale della luna Dafni sugli anelli di Saturno

Le onde gravitazionali indotte dal passaggio del satelline naturale di Saturno, Dafni, increspano l'anello A del gigante gassoso, in questa spettacolare immagine catturata dalla sonda Cassini.

Cassini took the image on January 16, 2017, while 17,000 miles (28,000 kilometers) away from the moon. Measuring 5 miles (8 kilometers) along its longest axis, irregular Daphnis resides in the 26-mile (42-kilometer) wide Keeler Gap in Saturn's outer A ring. The Keeler Gap seems narrower than it really is in this image because of foreshortening due to the spacecraft's viewing angle. You can just see grooves along the long axis of Daphnis in the image, as well as a few impact craters.
