According to this theory, the more a civilization grows and develops, the greater its energy needs will be due to the disproportionate growth of its population and the energy demands of its machines. The Kardashev scale was developed based on the idea that a civilization could consume energy based on its technological advancement. The scale was developed in 1964 by Nikolai Kardashev, a Russian astrophysicist who was researching extraterrestrial life. […]
This image is a real image of the center of the Milky Way. Normally, the center of the Milky Way is filled with many objects hidden from view because of the numerous stars and nebulae. But in this image, almost all of these objects are visible, except for one: the supermassive black hole at the center of the Milky Way. It's actually right in the middle of the image. Infrared images allow us to see objects hidden behind the nebulae […]
While sending astronauts to Mars in super-fast spacecraft powered by nuclear fusion engines may seem like the stuff of science fiction, scientists say it's actually doable. Based on laboratory tests, the team working on this technology reports that a trip to Mars could be achieved in as little as 90 days.
It will pierce you, and more. Scientists emphasize two things for certain. Putting any part of your body in front of a proton pair laser is a very bad idea. Each proton has 320 trillion particles, meaning its energy is 362 megajoules. That's enough energy to melt and pierce through tons of copper. Second, someone with such a death wish […]
Centuries from now, humanity may make it a tradition to prepare for an unprecedented celestial spectacle—the deliberate impact of an asteroid on the moon. NASA is currently planning a mission to capture an asteroid with a spacecraft and place it in orbit around the moon, so that astronauts can visit it for scientific research at any time. Of course, the asteroid shouldn't be left undisturbed after the astronauts are finished. […]
A new instrument called ArTeMiS has been successfully installed on the APEX—Atacama Pathfinder Experiment Telescope. APEX is a 12-meter-diameter telescope located in the Atacama Desert, operating at millimeter and submillimeter wavelengths. By examining the sky in the infrared and radio regions of the electromagnetic spectrum, the telescope provides astronomers with vital insights into the depths of the Universe. The new camera mounted on the telescope has revealed the Cat's Paw Nebula in remarkable detail.
