Get ready to see and hear about more UFO’s as people use drones with more frequency, in various environments, yielding whole new crops of UFO footage from brand new, and sometime unfamiliar, perspectives.
The bluish area in this colorized photo represents the difference in wavelength of reflected light from the Hapi region of the comet. This wavelength is likely the result of higher concentrations of frozen water near the surface of the comet.
The soap bars are grey in color, rectangular in shape, and bear the letter markings “RJF”, which as the stories are told, stands for “Rein Juden Fett”, or “pure Jewish fat”.
Astronomers have found for the first time, multiple separate images of one supernova bent around a galaxy. Each image is a bit older or younger than the others plus we may see the whole thing repeat itself in a few years.
This recently spotted phenomenon has so many layers of awesomeness. First off, these multiple supernova images are a breed of gravitationally lensed images called an Einstein Cross. Gravitational Lensing is an artifact of Einstein’s General Relativity which predicted that light follows the bend in space-time caused by gravity. The intense gravity well around a foreground object in space can therefore act like a huge lens bending and magnifying the light from a more distance background object far behind it. If the alignment is near-perfect, we see a ring (an Einstein ring) of smeared light around the foreground object like a galaxy or galaxy cluster. If the background object is small like a star, we instead see multiple points of light arranged like the outermost extremities of the letter T; this is an Einstein Cross.
Scientists have proposed an updated model of particle physics that predicts the decay of the Higgs Boson into the mysterious dark matter particles that make up a quarter of the universe.
The standard model of particle physics has been an amazingly successful at not only describing the particles and forces of nature but also predicting new particles that were later found. This is the hallmark of a theory that is clearly onto something. Cobbling an idea together to describe phenomena already known is one thing, but actually making predictions that are later verified means that your theory is, at some level, a worthwhile model of reality (or it is otherwise incredibly lucky). The final major particle predicted by the standard model was the Higgs Boson and its discovery in 2012 capped an amazing journey that started way back in the 1970s.
Researchers claim to discover why the retina of most vertebrates is built backwards with the light receptors behind a mesh of intervening cells and neurons. They say this is because there are a subset of these cells that focus the light onto the receptors. Is this the real reason though?
