An asteroid is a relatively small chunk of rocky minerals that orbits the Sun. When they swing by Earth, they are described as Near Earth Asteroids. Most of these rocky objects can be found orbiting in the asteroid belt between Mars and Jupiter. But nearly 1,400 of these have been classified as potentially hazardous to Earth, which means their orbit and size pose a reasonable threat to our safety. Most of the asteroids that enter the Earth's atmosphere are unable to withstand the heat and burn into a meteorite before…

A former NASA astronaut has come up with a plan to save the Earth from killer asteroids. Dr. Ed Lu, who has a doctorate in applied physics, is trying to find a way to discover dangerous asteroids with enough advanced warning to deflect them away from Earth. It’s a noble effort and one that could work together with other asteroid detection and deflection systems, like NASA’s D.A.R.T spacecraft. An algorithm could make finding killer asteroids easier https://www.youtube.com/watch?v=_GNxx_1ZgWE On Tuesday,…

The Hubble space telescope continues to showcase intriguing parts of our universe. Earlier this month, NASA shared an image of a hidden galaxy tucked behind the Milky Way. IC 342, also known as Caldwell 5, would be one of the brightest galaxies we’ve observed so far. But, instead, the galaxy is hidden by the thick cosmic dust of the Milky Way’s equator. Hubble just imaged this hidden galaxy tucked behind the Milky Way The full image captured of the hidden galaxy Caldwell 5. Image source: NASA, ESA, P. Sell…

Somewhere out in the cosmos, there's the physics equivalent of a unicorn. Catching even a glimpse of this oddity that looks like the isolated tip of a magnet would be like a beacon in the night, pointing the way to grand, unifying theories of absolutely everything.  Yet aside from one tiny exception in the early 1980s, nobody has seen anything that remotely looks like the fabled beast of particle physics, the magnetic monopole.Of course, physicists might simply be looking for them in all the wrong places. A new analysis…

via Open Road Films Sean Penn takes himself very seriously, and while his two Academy Award wins reinforce the undoubted fact he’s one of his generation’s finest talents, he also tends to rub a lot of people the wrong way. With that in mind, it wasn’t exactly unexpected that his self-indulgent detour into action hero territory in 2015’s The Gunman went down like a lead balloon. Once Liam Neeson proved that middle-aged character actors could reinvent themselves as unlikely ass-kickers, plenty of other stars of…

By ESA/Hubble May 22, 2022Hubble Space Telescope image of globular cluster Liller 1. Credit: ESA/Hubble & NASA, F. FerraroThe subdued red tones of the globular cluster Liller 1 are partially obscured in this view by a dense scattering of piercingly blue stars. In fact, it is thanks to Hubble’s Wide Field Camera 3 (WFC3) that we are able to see Liller 1 so clearly in this image, because the WFC3 is sensitive to wavelengths of light that the human eye cannot see.Liller 1 is just 30,000 light-years from Earth — making it…

The U.S. Securities and Exchange Commission (SEC) has fined Nvidia $5.5 million for allegedly failing to disclose the influence crypto mining had on its GPU sales during 2018. The agency said it settled charges against Nvidia “for inadequate disclosures concerning the impact of cryptomining on the company’s gaming business.” A cryptocurrency miner attached to a laptop Getty Images That said, although Team Green agreed to a cease-and-desist order and the fine itself, the SEC said the company is doing so “without…

When the RadExpand 5 was first unveiled, I was surprised to see the company go in this direction and replace the RadMini with a new model. But now that I’ve spent some good time in the saddle, I see exactly what Rad was thinking, because the folding RadExpand 5 e-bike draws on some of the best parts of every other e-bike in the company’s wide lineup. I’ll start by saying that it’s going to be hard for Rad Power Bikes to top their own RadRunner e-bike, which holds a special place in my heart as such an innovative…
