By Rob Picheta and Hafsa Khalil, CNN At first glance, the news all seems a bit too familiar. A new virus outbreak is detected. It starts spreading around the globe, case by case, country by country. Health authorities launch into action, tracking infections and issuing guidance. After a tortuous two years, it’s understandable that the

By Katie Hunt, CNN Megalodon, the giant shark that lived more than 23 million years ago and was inspiration for the movie “The Meg,” was almost four times bigger than the great white shark that cruises our oceans today. However, the two shark species, which once coexisted, likely hunted some of the same prey. This

By Ashley Strickland, CNN The Hubble Space Telescope has looked straight into the heart of a stunning galaxy. The observatory captured this head-on view of a grand design spiral galaxy, called NGC 3631, located about 53 million light-years away from Earth. The celestial system can be found in the direction of the Ursa Major constellation.

By Katie Hunt, CNN Some lucky night sky watchers caught a glimpse of a brand new meteor shower on Monday night, as Earth passed through the debris trail of a crumbling comet. The meteor shower peaked around 1 a.m. ET, with 10 to 25 meteors an hour spotted falling through the night sky, according to

By Megan Marples, CNN For these tiny robotic crabs, being small is a virtue. Engineers at Northwestern University in Evanston, Illinois, invented the world’s smallest remote-controlled walking robot, according to research published in the journal Science Robotics. Each one is about half a millimeter wide, which is smaller than the thickness of a United States

By Ashley Strickland, CNN This is the last time we’ll ever see a selfie from NASA’s InSight lander on Mars. And judging by the amount of dust coating the lander’s solar panels, it’s easy to see why. The stationary spacecraft captured the image on April 24 using its robotic arm, which will soon be placed

By Katie Hunt, CNN Fearsome predators like T. rex and towering, telescope-necked dinosaurs, such as Brachiosaurus, were warm-blooded creatures in the same way birds and mammals are, according to a groundbreaking new study. The question of whether the blood that coursed through dinosaurs’ giant frames ran warm or cold, like that of reptiles, is a

By Rob Picheta and Hafsa Khalil, CNN Vaccines, variants, natural immunity and better treatment options mean catching Covid-19 now isn’t the same as it was a year or two ago. But for millions of people who contracted the virus even in the pandemic’s first months, the impact of the disease lingers. As many as one

By Katie Hunt, CNN NASA’s Earth Observatory has released satellite images of an undersea volcano erupting. The image, taken on May 14 by the Operational Land Imager 2 on the Landsat 9 satellite, shows a plume of discolored water being emitted from the submarine volcano. The satellite is designed to capture high-resolution images of our
