First Interstellar Asteroid Wows Scientists3m16s

First Interstellar Asteroid Wows Scientists

Scientists were surprised and delighted to detect --for the first time-- an interstellar asteroid passing through our solar system. Additional observations brought more surprises: the object is cigar-shaped with a somewhat reddish hue. The asteroid, named 'Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated—perhaps 10 times as long as it is wide. That is unlike any asteroid or comet observed in our solar system to date, and may provide new clues into how other solar systems formed.

Golf Ball Pendulums Shapeshift And Form Amazing Spirals1m19s

Golf Ball Pendulums Shapeshift And Form Amazing Spirals

Pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. This is a series of 15 pendulums using golf balls. The shortest pendulum swings 57 times per minute. The next shortest one swings 56 times per minute, and so on, down to 43 swings per minute. This creates some pretty cool effects, the two most ostensible being that at 30 seconds, as consecutive pendulums are at opposing positions in their swings, and at 60 seconds, all 15 pendulums are in sync as they were when they started. All told, this took about 20 hours to construct and tune. The tuning had to be accurate down to the millimeter to obtain the precision observed! When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. In recent years, dramatic breakthroughs in science and technology have completely transformed our understanding of the golf swing. There is one phenomenon, however, that might deserve the label of “the secret” of power in the golf swing, and that’s the compound pendulum effect.

What The Betelgeuse Explosion Would Look Like From Earth22s

What The Betelgeuse Explosion Would Look Like From Earth

Orion, the massive star Betelgeuse is dying. It reached the end of its life and currently in the terminal throes of shedding vast bubbles of gas into space. Betelgeuse lies some 430 light-years from Earth. Note that determining distances, especially to red supergiant stars, is an unnerving problem in Astronomy. Estimates vary and are often revised, with some as high as 650 light-years, yet it’s already one of the brightest stars in Earth’s sky. The reason is that Betelgeuse is a supergiant star. However, such brilliance comes at a price. Betelgeuse is one of the most famous stars in the sky because it’s due to explode someday. Its enormous energy requires that the fuel be expended quickly, and in fact Betelgeuse is now near the end of its lifetime. In astronomical terms, someday soon it will run out of fuel, collapse under its own weight, and then rebound in a spectacular supernova explosion. When this happens, Betelgeuse will brighten enormously for a few weeks or months, perhaps as bright as the full moon and visible in broad daylight. When will it happen? Probably not in our lifetimes. But, in fact, no one really knows. It could be tomorrow or a million years in the future.

Betelgeuse: The impending Supernova you need to know about1m51s

Betelgeuse: The impending Supernova you need to know about

Check out this incredible video of the Betelgeuse 'killer' star - 1,400 times larger than our Sun that would swallow up Mercury, Venus, Earth, Mars and even Jupiter. The Betelgeuse star is a famous one among amateur astronomers not only for its size and brightness, but also because it is part of Orion, a bright winter constellation in the Northern Hemisphere.

Space Station Cosmonauts take a Walk in Space

Outside the International Space Station, Expedition 52 Commander Fyodor Yurchikhin and Flight Engineer Sergey Ryazanskiy conducted a spacewalk Aug. 17 to assess the condition of the exterior of the Russian segment of the complex and to install struts and handrails to facilitate future excursions. During the outing, Ryazanskiy manually deployed five small nanosatellites to collect data on a variety of scientific investigations. The spacewalk, which was the 202nd in support of space station assembly and maintenance, was the ninth in Yurchikhin’s career and the fourth for Ryazanskiy. Credit: NASA

Rare audio of indigenous languages saved by invention 100 years later3m57s

Rare audio of indigenous languages saved by invention 100 years later

Optical scan technology is helping researchers at the University of California (UC), Berkeley, preserve audio of 78 indigenous California languages, most of which were recorded more than a century ago. The recordings are on approximately 2,700 wax cylinders that are now barely audible due to issues such as mold. These are the only known sound recordings for several of the languages, and in many other cases, the recordings include unique speech practices and otherwise unknown stories and songs. With support from the National Science Foundation (NSF), linguist Andrew Garrett, digital librarian Erik Mitchell and anthropologist Ira Jacknis, all of UC Berkeley, are restoring these recordings. The researchers are using a non-invasive optical scanning technique that was developed by Lawrence Berkeley National Laboratory physicists Carl Haber and Earl Cornell. The collaboration with Haber and Cornell is enabling the NSF-funded research team to transfer all 100 hours of audio content from the wax cylinders and improve the recordings, finally making it possible to figure out which language is being spoken and what's being said. The rich Native American cultural collection will ultimately be accessible to indigenous communities as well as to the general public and scholars. The linguistic diversity of the world's estimated 7,000 languages is immense. Modern technologies like this one unlock the documentation to enable new community uses and scientific investigations. This research was co-funded by the National Endowment for the Humanities; grant number PD-230659-15. NSF support was provided by award #1500779, "Linguistic and ethnographic sound recordings from early twentieth-century California: Optical scanning, digitization, and access."

NASA's First 100 Days Of President Trump's Term1m17s

NASA's First 100 Days Of President Trump's Term

From a presidential call from the Oval Office with a record-breaking American Astronaut to announcing the discovery of Earth-sized planets outside our solar system, NASA's been busy during the first 100 days of President Trump’s term. Among the key moments was March 21 when President Trump signed the National Aeronautics and Space Administration Transition Authorization Act of 2017, the first comprehensive NASA authorization passed by Congress in more than six years. This bill helps ensure NASA remains at the forefront of exploration and discovery. NASA appreciates the strong support of the President, as well as our citizens in America and friends around the world. Credit: NASA

Time Lapse Of Tarantula Shedding Her Skin  In Only One Minute 58s

Time Lapse Of Tarantula Shedding Her Skin In Only One Minute

This is so fascinating! This is a short time lapse featuring a Brachypelma Smithi tarantula, named Pebbles, molting (shedding her skin). Pebbles is 11 years old and goes through this process at least once during a 1.5 year timeline. It was recorded over a 7-hour period, but with the time lapse, we can watch it all unfold in just one minute, incredible! This video makes the process look a lot shorter than it actually is. It is always so cool to see how nature works, especially when it's a tarantula shedding her skin! You don't see this very often! Brachypelma Smithi tarantulas are usually found around the central Pacific coast of Mexico and are also known as Mexican Red-Knee Tarantulas. They are usually found in dry areas with barely any vegetation, usually in deserts, or tropical forests. They live in burrows in rocky areas as the base of thorny vegetation like cacti. They are very large dark spiders and be quite intimidating if you aren't a spider lover. They usually won't cause any harm unless they are being threatened. In that case, they will show their fangs. Have you ever seen a tarantula before? Let us know in the comment section down below!
