Sunrise Shadows in the Sky by Emili Vilamala


http://apod.nasa.gov/

The defining astronomical moment of this September's equinox was at 12:44 UTC on September 22, when the Sun crosses the celestial equator moving south in its yearly journey through planet Earth's sky. That marks the beginning of fall for our fair planet in the northern hemisphere and spring in the southern hemisphere, when day and night are nearly equal around the globe. Of course, if you celebrate the astronomical change of seasons by watching a sunrise, you can also look for crepuscular rays.

Outlined by shadows cast by clouds, crepuscular rays can have a dramatic appearance in the twilight sky during any sunrise (or sunset). Due to perspective, the parallel cloud shadows will seem to point back to the rising Sun and a place due east on your horizon on the equinox date. But in this spectacular sunrise skyscape captured in early June, the parallel shadows and crepuscular rays appear to converge toward an eastern horizon's more northerly sunrise.

The rising Sun is pictured just behind the bell tower of a church in the town of Vic, province of Barcelona, Catalonia, Spain.

World’s First Hydrogen Race Car Passes FIA Crash Tests

The Pioneer 25 marks a momentous step in the world of motorsports as it passed the mandatory FIA (Fédération Internationale de l’Automobile) crash tests. Developed solely for Extreme H, the world’s first hydrogen-powered motorsport, the car has a top speed of 200 km/h (124 mph).





There have been some iterations of functional hydrogen rally and race cars that have been constructed as prototypes over the years, but none have ever been able to be successfully homologated for competition. So successful series of testing is significant – particularly given that hydrogen is still relatively new and rare as an automotive fuel, and well known to be explosive in certain mixtures with air.

It’s worth noting, though, that even where a tank is punctured and hydrogen gas escapes, it’s about 14 times lighter than air, and thus tends to rush upward at a rate of about 20 meters per second (66 ft/sec) – so according to the US DoE, it’s less likely to cause an explosion in practice than regular gasoline.

Those Aren't Dyson Spheres, They're HotDOGs





If there really are advanced alien civilizations out there, you’d think they’d be easy to find. A truly powerful alien race would stride like gods among the cosmos, creating star-sized or galaxy-sized feats of engineering. So rather than analyzing exoplanet spectra or listening for faint radio messages, why not look for the remnants of celestial builds, something too large and unusual to occur naturally?

The most common idea is that aliens might build something akin to a Dyson sphere. In their need for more powerful energy sources, an advanced civilization might harness the entire output of a star. They wrap a star within a sphere to capture every last photon of stellar energy. Such an object would have a strange infrared or radio spectrum. An alien glow that is faint and unique. So astronomers have searched for Dyson spheres in the Milky Way, and have found some interesting candidates.

One major search was known as Project Hephaistos, which used data from Gaia, 2MASS, and WISE to look at five million candidate objects. From this they found seven unusual objects. They appear to be M-type red dwarfs at first glance, but have spectra that don’t resemble simple stars. This kind of star-like infrared object is exactly what you’d expect from a Dyson sphere. But of course extraordinary claims require extraordinary evidence, and that’s where things get fuzzy.

Almost immediately after the paper was published, other astronomers noted that the seven objects could also be hot Dust-Obscured Galaxies, or hotDOGs. These are quasars, so they appear star-like, but are obscured by such a tremendous amount of dust that they mostly emit in the infrared. And their spectra can be quite different from a M-type star. So the challenge is to distinguish between a hotDOG and a Dyson sphere. Which is where a new paper on the arXiv comes in.

Rather than trying to specifically distinguish between the two, the authors instead look at the distribution of known hotDOGS. They found that statistically about 1 in 3,000 quasars are of the hotDOG type, so that a broad search for Dyson spheres would likely include some dusty quasars. The authors go on to note that any civilization powerful enough to build star-scale structures would also have the ability to obscure their infrared signal. We can’t simply assume that aliens would build a Dyson sphere in such an obvious way. Overall, the authors argue, the seven candidate superstructures can be accounted for by hotDOGs and other phenomena, thus there is currently no clear evidence for alien superstructures.

For motorheads.

The engine is the 24 cylinder liquid cooled Napier “Sabre”, which powered the British WWII fighter-bomber Hawker “Typhoon”.

I saw a cutaway museum exhibit of one, and iirc it was two stacked flat-12 banks, geared to a mid placed output shaft. Vid mentions early problems with cooling.

Sleeve valves, so close tolerances, and using aluminum for the block and steel for the cylinder liners, led to some esoteric metalurgy. Alloys to calm the former and exite the latter, to heat.

...”In this episode, Brad and I discuss the Napier Sabre engine, the heart of the Typhoon. Details are provided on how we must move forward with this aspect of the project to return JP843 to the air, and why the engine is such a special beast! More information on the engine is on its way as we dive into the Napier Sabre VII in our shop.”...
