Power over Wi-Fi

[Waaagh!]

Ce uita sa mentioneze e cum o sa ne creasca tuturor ciorchini intregi de cancer pe dupa urechi de la cat camp electromagnetic am ajuns sa incasam in permanenta de la toate telefoanele, routerele si antenele din jur.

On June 1, 2015, photographer Nicolaus Wegner was in South Dakota and saw a rare sight: a stationary supercell.

Normally these system move, blown by winds, but this huge rotating thunderstorm squatted over the landscape like an angry god. He shot a time-lapse video of it that is stunning.

A supercell is a rotating thundercloud; the spinning vortex in the middle is called a mesocyclone. Conditions need to be just so to create one. First you need a wind shear, where wind blows faster in one spot than another, so a blanket of air is flowing over another one. This sets up a rolling vortex, a horizontally rotating mass of air like the way a wave breaks when it gets to a beach. An updraft then lifts that vortex, which then spins vertically.

The warmer air in the vortex rises; this is called convection. If there’s a boundary layer of air above it, called a capping layer, it acts like a lid, preventing the vortex air from rising. It builds up power and can suddenly and explosively grow to a huge size. Wikipedia has a good description and diagrams of how this works.

The colors are amazing. As white light from the Sun goes through the cloud, two things happen: Red light is absorbed by water, and blue light gets scattered away from the direction of the Sun. So when you look toward the Sun, you see less blue, making it look red, and when you look toward the cloud itself the red light from the Sun is absorbed, making it look blue. The presence of hail sometimes makes the cloud look deep green or teal; the reason for this isn’t completely understood.

Philae Is Alive!

Fantastic news from the European Space Agency this morning: The Rosetta space probe lander Philae is awake!

Philae has been lost and incommunicado on the surface of the comet 67P/Churyumov-Gerasimenko since November, but yesterday, June 13, 2015 at 20:28 UTC, a signal from the lander was received by the European Space Operation Centre.

Hurray!

They received 85 seconds worth of data from Philae, and very interestingly, they also received “historical” data, information that had been recorded by the lander earlier and saved onboard, meaning it was awake at least once before during the past few months.

NASA released high quality renderings of Pluto

Impossibru!
E conceptia unui artist, nicidecum high res foto a lui Pluto.

[Waaagh!]

Daca ti-a supravietuit sonda pana acolo, cred ca ultima problema din lume e sa faca niste fotografii cat de cat rezonabile.

Nice place, already feels like home.

New Horizons va fi cel mai aproape de Pluto pe 14 iulie (sonda zboara de 9 ani jumatate), adica la 12500 km. Deocamdata zboara cu 52416 kmh catre Pluto, deci e foarte departe, inca. Rezolutia cea mai buna va fi de 1 pixel = 50 m.
