For most of human history, the distant ‘celestial sphere’ was regarded as perfect and unchanging. Stars remained in place, planets moved predictably, and the few rogue comets were viewed as atmospheric phenomena. This began to change with the Danish astronomer Tycho Brahe’s observation of the supernova of 1572 – apparently, a new star – and his studies of the Great Comet of 1577, which he proved was actually a distant object. Nonetheless, the impression of permanence is strong. There are very few astronomical objects that noticeably vary to the naked eye: only the brightest comets, novae and supernovae. For observers in the northern hemisphere, the last naked-eye supernova was in 1604.Continue reading What high-speed astronomy can tell us about the galactic zoo
While orbiting over South America” on March 17, 2019, an astronaut aboard the International Space Station (ISS) shot this photograph of the Atacama Desert, the driest non-polar desert in the world, and the numerous salt flats in the Andes Mountains along the border of Chile and Bolivia. The centerpiece is the Salar de Uyuni, the largest salt flat on Earth.Continue reading Salar de Uyuni from space
Smart technology may have started as a way to make modern life more convenient, but it has significant potential to help us conserve resources and address environmental problems, too. Humans are undoubtedly having a huge impact on the planet, and technology is both a cause and a possible solution to the damage we’re doing. From small-scale changes in individual homes to large-scale efforts such as recycling carbon dioxide and carbon capture storage, it is possible to create systems of technology that work with, not against, the environment.Continue reading Smart Technology: Protecting Your Home and Saving the Planet
New and developing technologies like artificial intelligence, robotics, and virtual and augmented reality (among others) are really cool. We love to see how robots can differentiate between objects, artificial intelligence can assist psychologists, and virtual reality can allow us to enter new worlds. But how can today’s youth reap the benefits of these amazing technologies in their everyday lives to prepare them for their future?Continue reading 7 Ways New Technologies are Preparing Our Youth for the Future
On April 11, 2019, the American space company SpaceX launched its second Falcon Heavy rocket, and this time, landed all three boosters successfully.Continue reading SpaceX launches the second Falcon Heavy
The alternating current motor was invented by Nikola Tesla over 100 years ago, paving the way for the Teslas and other electric vehicles (EV) we see today. Many hope that this sustainable energy source will eventually replace traditional internal combustion engines and drastically reduce the amount of carbon emissions around the world.Continue reading Inside an electric car
This is the first image ever of a black hole. The EHT (Event Horizon Telescope) captured an image of the nearby elliptical galaxy Messier 87’s (M87’s) supermassive black hole in the center of the Virgo galaxy cluster, 53 million light-years away. It was revealed today (April 10, Wednesday) in multiple press conferences around the world, and was the result of a global collaborative effort from over 200 scientists working with the EHT.Continue reading First-ever image of a Black Hole
In March 2019, NASA’s Mars Curiosity rover captured two solar eclipses created by each of the planet’s tiny moons, Phobos and Deimos.Continue reading NASA’s Curiosity Rover captures two solar eclipses on Mars
On April 15, 1912, RMS Titanic, which was the largest ship afloat at the time she entered service, sank in the North Atlantic Ocean after colliding with an iceberg during her maiden voyage from Southampton to New York City.
It was one of the deadliest commercial marine disasters in modern history: of the estimated 2,224 passengers and crew aboard, more than 1,500 died.
Here is a real-time animation of the RMS Titanic’s sinking below, published by Titanic: Honor And Glory channel.Continue reading Titanic sinking in real time (2 hours and 40 minutes)
On June 12, 2009, a fortuitous orbit of the International Space Station (ISS) made it possible for an astronaut on board to capture Sarychev Volcano in the early stages of the eruption.Continue reading Sarychev Volcano eruption from the ISS – Amazing Video
