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 John Blake, CNN Sports, it’s been said, reveals character. It also reveals something else: philosophy. There’s no better example of this than Rafael Nadal, the 35-year-old professional tennis player who’s competing this week at the French Open. Nadal is not just a gladiator on the court — he’s a philosopher at heart. You may

By Ashley Strickland, CNN Ancient volcanic eruptions on the moon could provide an unexpected resource for future lunar explorers: water. Between 2 billion and 4 billion years ago, the moon was a volcanic hotspot. Tens of thousands of volcanoes were erupting on the surface, releasing hundreds of thousands of square miles of lava across the

By Paula Newton, CNN Toronto Police fatally shot a man who was seen carrying a firearm near three schools in the Scarborough area Thursday, police said. Officers responded to reports of a man carrying a firearm and “there was an interaction” between officers and the man, according to the Special Investigations Unit in the Canadian

The 134 sites correspond to Indigenous settlements that date to Roman occupation. A study detailing the findings published Tuesday in the journal Antiquity. Construction of Hadrian’s

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

By Ashley Strickland, CNN Measuring the expansion rate of the universe was one of the Hubble Space Telescope’s main goals when it was launched in 1990. Over the past 30 years, the space observatory has helped scientists discover and refine that accelerating rate — as well as uncover a mysterious wrinkle that only brand-new physics

By Zoe Sottile, CNN Things are looking up for the greater one-horned rhino. The massive mammal, also called the Indian rhinoceros, saw its global population reach its highest level since the 1980s, according to the International Rhino Foundation, a Texas-based nonprofit focused on rhino conservation. There are now a total of 4,014 greater one-horned rhinos
