The Total Area Of Solar Panels It Would Take To Power The World, Europe, And Germany

Planets i learned about via youtube while procrastinating my english essay

Planet 55 Cancri e is basically a giant diamond. like the planet is a diamond. and it would be worth $26.9 nonillion

Planet Gliese 436 b is an ice planet that is constantly on fire do to its close proximity to its parent star. the ice doesn’t melt bc the planet’s gravity is so strong it physically prevents the ice from melting

Planet HD 189733b rains sideways glass…. constantly

Planet J1407-B has planetary rings that are 200x the size of saturn. if saturn’s ring were as big as J1407-B’s we’d be able to see them with our naked eye from earth AND they would dominate our sky and look larger than a full moon

Planet Wasp-12b rotates so close to its parent star that its slowly being consumed by the it

Planet Gliese 581c is one of the candidates for a planet that can support life however it orbits a tiny dwarf star and is tidally locked so one side is constantly subject to immense sunlight while the other is constantly in darkness. there’s a small area of the planet however, that is just the right temp to support life. u just can’t step out of said area. the skies are red and the plants would have be a black color instead of a green bc they would use infrared light for photosynthesis. (a message was actually sent to the planet in 2008 in hopes that there’s life on the planet but the message wont reach the planet until 2029).

Planet GJ 1214b is a water planet nicknamed “water world” is has no land at all and the water is so deep it goes down miles all the way to the planet’s core.

Planet Wasp-17b is the largest planet discovered thus far. its so large its existence contradicts our understanding of how planets are formed. and it has a retrograde orbit, so it orbits in the opposite direction of its parent star.

Planet HD 188753 has 3 suns you should have triple shadows and there would be almost daily eclipses. and no matter which direction u face on the planet u would always see a sunset

Planet HD106906b is the loneliest planet discovered thus far. its known as “super jupiter” bc its 11x bigger than jupiter. it orbits its parent star at a distance of 60 billion miles (which is v strange) hence why its the loneliest planet.

Planet Tres 2b is the darkest planet known. it reflects less than 1% of light (it reflects less light than coal and black acrylic paint). the tiny part of the planet that does reflect light is red making the planet glow a dim red.

some of my favourite absolutely SICK facts about the trappist-1 exoplanets: - theyre all very close to one another and to their star, so the length of a year on them varies from 1 to 20 DAYS - since they’re so close, the star appears a lot bigger than our sun from earth, and from one planet you could easily see the rest, some would even appear bigger than the moon from earth. you could literally see the surface of another planet with the naked eye!!! - they’re probably tidally locked to their star like our moon is locked to earth, meaning only one side of a planet ever faces the star, and on the other side it’s always night. the sun never sets or rises on any of the planets - the star is red, so the sunlight is red/orange, meaning if, for example, plants were to grow there, they could be black and that’s just what we know now, imagine how much cool stuff we have yet to discover about the trappist-1 system

Polymer absorbs water and expands. It keeps almost the same refractive properties as water and appears invisible.

The polymer is Sodium Polyacrylate (thank you, thecraftychemist!)

Vera Rubin, the groundbreaking astrophysicist who discovered evidence of dark matter, died Sunday night at the age of 88, the Carnegie Institution confirms.

Rubin did much of her revelatory work at Carnegie. The organization’s president calls her a “national treasure.”

In the 1960s and 1970s, Rubin was working with astronomer Kent Ford, studying the behavior of spiral galaxies, when they discovered something entirely unexpected — the stars at the outside of the galaxy were moving as fast as the ones in the middle, which didn’t fit with Newtonian gravitational theory.

The explanation: Dark matter.

Adam Frank, an astrophysicist who writes for NPR’s 13.7 blog, described dark matter by comparing it to a ghost in a horror movie. You can’t see it, he writes — “but you know it’s with you because it messes with the things you can see.”

Adam continued:

“It was Vera Rubin’s famous work in the 1970s that showed pretty much all spiral galaxies were spinning way too fast to be accounted for by the gravitational pull of the their ‘luminous’ matter (the stuff we see in a telescope). Rubin and others reasoned there had to be a giant sphere of invisible stuff surrounding the stars in these galaxies, tugging on them and speeding up their orbits around the galaxy’s center.”

Cristobalite is a silica polymorph that is thermodynamically stable only at temperatures above 1470°C, up to the melting point at 1705°C, at atmospheric pressures. It commonly metastably persists or even forms at much lower temperatures in silica-rich volcanic and sedimentary environments. It can form crystals in cavities, probably vapour-deposited, or spherulites in obsidian or other silicic volcanics.

Hematite is rather variable in its appearance - it can be in reddish brown, ocherous masses, dark silvery-grey scaled masses, silvery-grey to black crystals, and dark-grey masses, to name a few. What they all have in common is a rust-red streak.

According to NASA, a neighboring star has 7 Earth-like planets in its orbit

Seven Earth-like planets have been found orbiting a sun not too far — in space terms, at least — from our own.

NASA announced Wednesday that the planets resemble Earth in composition and spacing from their star, which means their conditions might be favorable to liquid water and life, Time reported.

“The planets form a very compact system,” Michaël Gillon of Belgium’s University of Liège, said in a teleconference, according to Time. “They are very close to their star and are reminiscent of the system of moons that orbit Jupiter. They could have liquid water and life.”

Astronomers studied the star, Trappist-1 — which, at 39 light years away from Earth, is considered a relative neighbor — for six years, using telescopes located all over the world, plus the Spitzer Space Telescope. Read more (2/22/17 2:04 PM)

The Chimaera, known informally as the “ghost shark” or “rat fish”, is a deep sea cartilaginous fish in the order Chimaeriformes. Living at over 8,000 ft below the surface, the Chimaera is well adapted to the deep, dark sea. The dots on its nose are sensory organs that detect electrical fields in the water - helping the Chimera find its prey. While little is known about the Chimaera’s diet, it’s speculated that it feeds on molluscs and crustaceans that it crushes open with the grinding plates in its mouth. The spines on the top of its body are loaded with venom; the Chimaera uses these spines to defend itself.
