More than eight months after the underwater volcano near Tonga erupted on Jan. 14, scientists are still analyzing the impacts of the violent blast, and they’re discovering that it could warm the planet. Recently, researchers calculated that the eruption of Hunga Tonga-Hunga Ha’apa spewed a staggering 50 million tons (45 million metric tons) of water

Lakes appearing in Alaska because of melting permafrost are “belching” methane into the atmosphere, a scientist working with NASA said. These lakes, called thermokarsts, are so full of the climate-damaging gas that it can be seen bubbling to the surface. More and more of these lakes are appearing as Alaska’s permafrost thaws with rising temperatures

In the wacky gravitational environment in the heart of our galaxy, astronomers have found a gas blob orbiting our supermassive black hole at superspeed. Its characteristics are helping astronomers probe the space immediately surrounding Sagittarius A* in the search for answers about why the galactic center flickers and flares across the entire electromagnetic spectrum. Their

A woman in labor is having a terrible time and suddenly shouts out: “Shouldn’t! Wouldn’t! Couldn’t! Didn’t! Can’t!” “Don’t worry,” says the doctor. “These are just contractions.” Until now, several theories have sought to explain what makes something funny enough to make us laugh. These include transgression (something forbidden), puncturing a sense of arrogance or

Unidentified deep-sea “blue goo” creatures recently left scientists scratching their heads after they spotted the mysterious blobs hanging out on the seafloor in the Caribbean. During a live stream of the expedition, team members discussed what the gloopy globules could be, but none of the researchers could come up with a definitive answer. Multiple blue

Have you ever wondered exactly how many ants live on Earth? Possibly not, but it’s certainly a question we’ve asked ourselves. Our research published today provides an approximate answer. We conservatively estimate our planet harbors about 20 quadrillion ants. That’s 20 thousand million millions, or in numerical form, 20,000,000,000,000,000 (20 with 15 zeroes). We further

An instrument designed to detect seismic activity on Mars has just revealed an incredibly cool new ability, detecting faint tremors from meteorites impacting the red planet. By combining data collected from the NASA’s Mars InSight lander with information from the Mars Reconnaissance Orbiter researchers have successfully linked those ground-shaking booms with freshly formed craters. Not

Burning the world’s remaining fossil fuel reserves would unleash 3.5 trillion tonnes of greenhouse gas emissions – 7 times the remaining carbon budget to cap global heating at 1.5 degrees Celsius – according to the first public inventory of hydrocarbons released Monday. ​Human activity since the Industrial Revolution, largely powered by coal, oil, and gas,

Records of solar eclipses from a millennium and a half ago have allowed scientists to refine measurements of Earth’s changing rotation. A painstaking review of historical documents from the Byzantine Empire has given scientists timings and locations for five solar eclipses. The results, although consistent with previous findings, place new, tighter constraints on Earth’s variable

An ancient fossil from one of our planet’s earliest vertebrate organisms was found concealing an exciting surprise. Inside a 380 million-year-old fossilized armored fish, paleontologists identified a mineralized heart, one that was exceptionally well-preserved in three dimensions. This is an incredible find. Soft tissues are rare in the fossil record, tending to decompose before fossilization
