By Ashley Strickland, CNN (CNN) — The scintillating cosmic phenomenon of a total solar eclipse will be visible to millions of people across parts of Greenland, Iceland, northern Russia, Spain and Portugal on August 12. It’s the first of three eclipses anticipated over Spain in the next two years. The best way to prepare for

By Sneha Dhandapani, CNN Bobcat Cave near Huntsville is home to the endangered Alabama cave shrimp, two species of cave crayfish and the southern cavefish. Those were all Dr. Matthew Niemiller expected to find when he set out to survey the cave system last year. Instead, he discovered a bizarre-looking fish, previously unknown to science.

By Laura Paddison, CNN (CNN) — Europe’s summer of extraordinary heat and drought has pushed some of its rivers to record lows, revealing long-submerged relics from ancient bones to century-old shipwrecks. The remains of what’s believed to be an ancient mammoth were discovered Wednesday on the newly exposed riverbed of the Danube in northern Bulgaria,

By Jacopo Prisco, CNN (CNN) — Scientists say they have detected promising signs that a planet orbiting a star 49 light-years from Earth could have an atmosphere, making it potentially suitable for life. Called LHS 1140b, the object is about five times the mass of our planet, or a “super-Earth.” This planet orbits around its

Barbie Latza Nadeau Rome (CNN) — The new trees meant to provide much-needed shade in Rome’s Piazza Risorgimento were burnt to a crisp. Benches in dark plastic and wood were searingly hot. Several of the large flower pots had been gutted of their foliage entirely. The bushes lining the entrance were a burnt orange color.

By Ashley Strickland, CNN (CNN) — A total solar eclipse will create a celestial spectacle in the sky for the first time in more than two years on August 12. A total solar eclipse happens when the moon passes between the sun and Earth, casting a shadow on our planet that fully blocks the sun’s

By Amen Galinato, CNN A double meteor shower peak will occur this week — but sky-gazers might have a difficult time catching a glimpse of the cosmic activity. The Alpha Capricornids are active from early July to mid-August, and the Southern Delta Aquariids are active from mid-July to mid-August, but both are expected to reach

CNN By Laura Paddison, CNN (CNN) — The vast blazes ripping through southwestern France burned so intensely they created a powerful, fire-generated thunderstorm. This rare phenomenon is sometimes seen in the kinds of megafires that afflict the US and Canada, but was unprecedented in France, until now — and it’s just one sign that Europe

By Amen Galinato, CNN July’s full moon will grace the sky this week. Called the buck moon, it will rise in the east and reach peak illumination at 10:36 a.m. ET on Wednesday, according to The Old Farmer’s Almanac, though the moon will still look full before and after its peak. Sky-gazers will have “flexibility

By Mindy Weisberger, CNN (CNN) — Scientists have revised the longstanding picture of “Nutcracker Man” — an extinct hominin, or human relative, nicknamed for its large teeth and powerful jaw muscles — thanks to fresh analysis of fossil footprints from a site in Kenya. Nutcracker Man, whose species is scientifically known as Paranthropus boisei, lived

By Laura Paddison, CNN (CNN) — When astrobiologist Adam Frank walked into the office of NASA scientist Gavin Schmidt, he had what he believed was the weirdest question: do aliens experience climate change? It took just moments for Schmidt to out-weird him. Frank, a University of Rochester professor who looks for signs of life in

By Sneha Dhandapani, CNN Four miles from the Eiffel Tower, a photographer captured the full moon’s path over a pink Paris skyline. In China, another photographer snapped a night sky of falling stars. These are just two of the submissions short-listed in the 18th annual Astronomy Photographer of the Year competition. Organized by the Royal

By Mindy Weisberger, CNN (CNN) — How hard do you have to ram a fish to make it explode? Ask an orca. Barreling into large, heavy fish with enough force to blast them into instant chum is a previously unknown collaborative feeding strategy among orcas, scientifically called Orcinus orca, also known as killer whales. But

By Laura Paddison, CNN (CNN) — The combined water level in two of the United States’ biggest reservoirs, Lake Powell and Lake Mead, has fallen to a historic low, in what experts are calling a significant moment in the Colorado River crisis — threatening a water system that supplies tens of millions. On July 12,

By Jackie Wattles, CNN (CNN) — As the number of satellites orbiting Earth continues to grow, so does the risk of crashes between these spacecraft. Such collisions could create fields of debris, potentially rendering entire areas of orbit useless. Objects in space have crashed, or had near misses, in the past. But while such incidents

By Laura Paddison, CNN (CNN) — Houseboats lie perched on desiccated riverbeds, receding water levels have left wide stretches of newly exposed riverbank and the shipping sector is bracing for trouble. The low-lying Netherlands is used to grappling with too much water; now it’s struggling with too little. On Thursday, the country declared an official

By Andrew Freedman, CNN (CNN) — Putting your own mask on before assisting others was only supposed to be a safety instruction on an airplane, but it has applied to everyday life in the urban corridor from Washington, DC, to Boston where, for the second time in four years, smoke from wildfires in Canada turned

By Ashley Strickland, CNN (CNN) — Pompeii is often thought of as an undisturbed time capsule, a once-bustling port that fell silent after Mount Vesuvius erupted and blanketed the ancient Roman city with a thick layer of ash in AD 79. “It is such a great persistent narrative,” Dr. Steven Tuck, professor and head of
