If there was a giant hole in our planet, would we fall freely through it or would we perish in its center? Such questions are asked by Life Noggin on Youtube. Given gravity, momentum, and several other forces that would affect the fall, all formulated precisely with the help of mathematics, they think they have discovered what will happen in such a scenario. Find out the answer to the question in the video below:
The Moon has always fascinated the man. This mysterious gigantic rock orbiting the Earth has had an eternal presence in all facets of human culture for thousands of years. The Moon is a perfect example of the delicate balance found everywhere in nature. One photographer has recently created the clearest picture of its craters by combining numerous shots of the lunar line where light meets dark. To reveal the surface of the moon in detail, lunar enthusiast Andrew McCarthy stacked thousands of pictures together over lunar phases. Californian-based astrophotographer took two weeks’ worth of frames of the waxing moon,...
In neutron stars we can find the strangest and most dangerous substance in The Universe: Strange Matter. What is Strange Matter, how dangerous is it and what can it tell us about the beginning of the Universe? See the answer in this incredibly interesting video posted by the YouTube channel Kurzgesagt – In a Nutshell.
Neil deGrasse Tyson is an American astrophysicist and author. He is also one of the most compelling speakers when it comes to talking about science. In the short video below, Tyson is asked the following question: “What is the most astounding fact that you can share with us about the universe? Now that’s a pretty profound question. And here is what he is saying: “The most astounding fact is the knowledge that the atoms that comprise life on Earth, the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures....
If you want to feel infinitely insignificant, then this interactive map showing the location of 119,617 stars around us, will certainly help you. It’s called 100,000 Stars and was created by Michael Chang and the Data Arts team from Google’s Chrome Experiment lab. Thanks to the map, you can walk through our solar system and even go beyond the Milky Way. The view is amazing. The good news in this case is that you don’t even need Chrome to run it. And don’t miss to “Таке а Tour” by pushing the Play Button on the top-right corner! Here are some...
European astronomers have found the nearest black hole to Earth, according to Associated Press. It is so close that two stars dancing around it can be observed it without a telescope. The black hole, which is lurking 1,000 light-years from Earth in the southern constellation of Telescopium, belongs to a system with two companion stars that are bright enough to observe with the naked eye. But you won’t be able to see the black hole itself; the massive object has such a strong gravitational pull that nothing — not even light — can escape it. Astronomers discovered this black hole while...
Our Solar System is weird. And not only because of the existence of this blue planet full of living things, but also because of the lack of gas giants like Jupiter at close distances to the Sun. Over the last few decades, scientists have discovered and confirmed more than 1,000 exoplanets, planets, orbiting other stars. But these star systems are quite different from the solar system – their large planets orbit their stars as close as Mercury orbits the Sun. Such exoplanets, called “hot Jupiters,” are quite common in other star systems, but strangely, they have disappeared from our. But...
Each Planet from the Solar System rotates at a specific speed and this animation shows how different these rotations are. It is the work of Dr. James O’Donoghue, a planetary scientist at the Japan Space Agency who once worked for NASA. The video shows how fast each planet rotates around its axis and compares the cosmic bodies with each other. For example, Jupiter rotates 2.4 times faster than Earth. So let’s have a look!
These days, in the evenings with clear sky, many people had the opportunity to see the “caravans” of Starlink satellites. Elon Musk’s “Starlink” project for a Broadband Internet sent 60 new low-orbit satellites without a problem on Wednesday last week, bringing the total constellation to 420. The advent of SpaceX’s Starlink satellite network, which will consist of many thousands of satellites, can seriously hinder astronomical observations. How can Starlink satellites be found in the sky? When the weather is cloudless, you can watch satellite in the night sky. Satellites are often visible as a bright point of light moving in...
