Man Found The Stoplight Cameras Were Activated During Yellow Lights And Decided To Cut The Wires Of It.

guys at my university I have a part time job where my sole responsibility is filling up the piano humidifaction systems with water

I literally am a piano waterer & tbh I kinda feel like I’m thriving

A Lunar Corona with Jupiter and Saturn : Why does a cloudy moon sometimes appear colorful? The effect, called a lunar corona, is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar Coronae are one of the few quantum mechanical color effects that can be easily seen with the unaided eye. Solar coronae are also sometimes evident. The featured composite image was captured a few days before the close Great Conjunction between Saturn and Jupiter last month. In the foreground, the Italian village of Pieve di Cadore is visible in front of the Sfornioi Mountains. via NASA

My understanding of phylogenetics is definitely limited so maybe I'm the one who's been getting it wrong this entire time, but if you haven't done so already would you mind explaining the studies about falcons being part of the Australaves clade? I find a lot of people saying things like "falcons are closely related to parrots" which I feel is a bit misleading, but again I could be wrong. Thanks in advance!

Sure! Australaves is the name given to a clade containing the seriemas, falcons, parrots, and passeriform birds. This group was first discovered by genetic analyses in the mid-2000s. As one might expect, this was a very unexpected finding, because prior to this no one had considered that all of these birds might be closely related to each other. (For example, seriemas were traditionally thought to be more closely related to cranes, falcons were thought to be more closely related to hawks, passeriforms were thought to be more closely related to woodpeckers, and so on.)

However, many more genetic studies on birds have been done since then by different research teams sampling different types of genes, vastly greater amounts of genetic data, and larger numbers of bird species, and Australaves has been consistently supported by nearly all of these. We can be pretty confident at this point that Australaves is a real clade.

Within Australaves, parrots and passeriforms are each other’s closest living relatives, and falcons are most closely related to the clade uniting both of them (which has been given the long name of Psittacopasserae). So it would not be incorrect to say that falcons are closely related to parrots, because parrots are indeed among the closest living relatives that falcons have.

However, I’ve occasionally seen people claim that parrots alone are the closest living relatives of falcons, and that is not correct. Instead, parrots and passeriforms are together the closest living relatives of falcons, and falcons are equally closely related to both (much like how a pair of siblings is equally closely related to their first cousin, instead of the cousin being more closely related to one sibling than to the other). The group containing falcons, parrots, and passeriforms (but not seriemas) has another mouthful of a name, Eufalconimorphae!

just came up with a really good 4 word cooking horror story but idk if you guys are ready for it

The road to the Vehicle Assembly Building at Kennedy Space Center. Completed in 1966, the VAB was originally intended for the vertical stacking of the Saturn V rocket during the Apollo Program era. During the Space Shuttle era, shuttle orbiters were mounted to fuel tanks & rocket boosters. The VAB is the tallest building (outside an urban area) in the US. It was the tallest building in Florida until 1974 & is the largest single story building in the world at 526 feet. At 129,428,000 cubic feet, it’s larger than your average 1-bedroom apartment.

Martian Chiaroscuro : Deep shadows create dramatic contrasts between light and dark in this high-resolution close-up of the martian surface. Recorded on January 24, 2014 by the HiRISE camera on board the Mars Reconnaissance Orbiter, the scene spans about 1.5 kilometers. From 250 kilometers above the Red Planet the camera is looking down at a sand dune field in a southern highlands crater. Captured when the Sun was about 5 degrees above the local horizon, only the dune crests were caught in full sunlight. A long, cold winter was coming to the southern hemisphere and bright ridges of seasonal frost line the martian dunes. The Mars Reconnaissance Orbiter, one of the oldest operating spacecraft at the Red Planet, celebrated the 15th anniversary of its launch from planet Earth on August 12. via NASA
