NASA’s Juno just sent back a photo of Jupiter that looks too insane to be real

NASA’s Juno spacecraft has been hanging around Jupiter for a while now, sending back some of the most jaw-dropping photos that mankind has ever captured, but its latest snapshot might be its most impressive yet. Cruising high above the planet’s massive, swirling cloud tops, Juno shot a photo in December that is really one for the ages. Like a cauldron of milky liquid, this photo of the mighty Jupiter looks more like a giant painting than a planet. With violent storms raging on its surface, the largest planet in our Solar System is one seriously huge piece of eye candy. Here is a video in which the images are reconstructed into 3D:
“Jupiter completely fills the image, with only a hint of the terminator (where daylight fades to night) in the upper right corner, and no visible limb (the curved edge of the planet),” NASA explains of the photo. “Juno took this image of colorful, turbulent clouds in Jupiter’s northern hemisphere on Dec. 16, 2017 at 9:43 a.m. PST (12:43 p.m. EST) from 8,292…

Stephen Hawking's B'Day special: 10 Mind Blowing Facts about Stephen William Hawking

Stephen William Hawking, is widely regarded as one of best minds in physics in the 21st century. He shot to fame after his path breaking proof of the “Big Bang Theory” which said that the universe started from a singularity in space and time. Author of the bestselling popular science book “A Brief History of Time”, Hawking has strived to make his work more accessible to the general public. He has also famously survived inspite of having Motor Neuron Disease, even though he was given only 2 years to live when he was diagnosed at a very young age. Here are a few interesting facts and stories about Professor Hawking that you probably did not know: #1. Hawking was not a bright kid in school. Even though right now we regard Hawking as one of the greatest minds on this planet, he was not a very bright kid in school. When he was 9 years old, his grades were amongst the worst in class and even later with some effort he could bring them up to only about average. But most of his teachers agree …

What is a Black Hole? Answers of Few Biggest Questions about BLACK HOLES

What is a Black Hole? Black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is
 so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with
 special tools can help find black holes. The special tools can see how stars that are very close to black
 holes act differently than other stars. see the scale video about BLACK HOLES
How Big Are Black Holes?
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom.
 These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or
 "stuff," in an object. Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the
 sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy…

How Big is The Universe

How Big is The Universe
         Our brains struggle to comprehend how big the universe is because everything here
 on Earth, and even the Earth itself, is very small when compared to the immense scale of
 the universe. BEST UNIVERSE VIDEO While we imagine light to be instantaneous, photons of light actually take time to travel from one side of the room to
 the other.So let's think about it a different way, using something we see and interact with every day… . subscribe BEST SPACE PORTAL ON YOUTUBE In the time it took you to read this far, a photon of light leaving the Sun has travelled about 10 million kilometres –
equivalent to travelling around the Earth 250 times. Light that leaves our second nearest star, Proxima Centauri, takes just over four years to reach Earth and so we can
 define it as four light years away. As such, if you were to look at Proxima Centauri, you would not be seeing the star as it is right now, but how it 'was' 4
years ago! We see all things in the …

Newton's Birthday Special: 10 Things You Didn't Know About Isaac Newton

10 Things You Didn't Know About Isaac Newton

Happy Birthday to Isaac Newton (sort of: skip to #5 for the scoop on that)! Although he's been a household name since his time, there's more to Isaac than meets the apple. Here are 10 facts you may not have known about Newton.

 He really did not like his stepfather. Newton was an avid list maker and one of his preserved lists included all of the sins he felt he had committed up until the age of 19 (his age at the time). One of them included, "Threatening my father and mother Smith to burne them and the house over them." You can't hardly blame the guy, though. When Smith proposed to Isaac's mother, Isaac wasn't part of the deal. The three-year-old Isaac was sent to live with his grandmother. 2. He wasn't expected to survive as a child. He was born quite premature: an estimated 11 to 15 weeks early. His mother said he could fit in a quart-sized cup upon birth. 3. That apple thing? Never happened. At least,…



NASA’s James Webb Space Telescope, scheduled to launch in 2018, will be the largest observatory ever sent into orbit, representing the next generation of giant space telescopes.
In order to peer deeper into space and time than any telescope has before, the JWST relies on cutting-edge optical science and engineering, some of which the University of Arizona has developed. 

FactsThe mirror on James Webb Space Telescope will be made of beryllium, which is lightweight yet strong, and can withstand very cold temperatures. The JWST has to be kept at about -375 degrees Fahrenheit for its instruments to function properly.The JWST’s mirror is covered in a thin layer of gold, because gold improves the mirror’s reflection of infrared light. Because the gold is pure and soft, it will be shielded by a protective layer of glass.The sunshield on James Webb Space Telescope is 70 feet by 48 feet, or roughly the size of a tennis court.All in…



.      The HST’s history is longer than you might have thought, going back to just after World War II. In 1946, the astronomer Lyman Spitzer (1914-97) identified the main advantages that a space-based observatory would have over ground-based telescopes. Spitzer spent much of his career to pushing for the building of a space telescope. 2.      Originally the HST was to have been bigger. NASA began seriously planning it in the mid-1970s. It was originally proposed to have a mirror diameter of 3m, but this was reduced to 2.4 m to save money. 3.      The HST is still bigger than you might think. It weighs 11 tonnes and is 15.9 m long. That’s nearly as long as a couple of Routemaster doubledecker buses (each 8.4m long). 4.      The HST doesn’t use as much power as you think. It uses about 2800 watts, while a typical kitchen kettle is rated at 2200 watts. Hubble gets its power from a couple of solar panels (each 2.6 x 7.1 m). 5. …
