Betelgeuse star had an unprecedented massive eruption

Betelgeuse star had an unprecedented massive eruption

Betelgeuse first drew attention in late 2019 when the star, which glitters like a red gem in the upper-right shoulder of Orion, experienced an unexpected darkening. The supergiant continued to grow sun in 2020. Some scientists speculated that the star would explode as a supernova, and they’ve been trying to determine what happened to it … Read more

August full moon: When to see the sturgeon supermoon

August full moon: When to see the sturgeon supermoon

Named by the Native American Algonquin tribe after sturgeon fish that were more easily caught in the Great Lakes and other bodies of water during this time of year, the sturgeon moon ends 2022’s series of four supermoons, which began in May, according to The Old Farmer’s Almanac. After sunset, look toward the southeast to … Read more

New image of colliding galaxies previews Milky Way’s fate

New image of colliding galaxies previews Milky Way's fate

The Gemini North telescope, located on the summit of Maunakea in Hawaii, spotted the interacting spiral galaxies about 60 million light-years away in the Virgo constellation. The galactic pair NGC 4567 and NGC 4568, also known as the Butterfly galaxies, have just begun to collide as gravity pulls them together. In 500 million years, the … Read more

Earth had shortest day since atomic clock was invented

Earth had shortest day since atomic clock was invented

Scientists recorded the shortest day on Earth since the invention of the atomic clock. A rotation is the length of time the Earth takes to spin once on its axis, which is roughly 84,600 seconds. The previous record was documented on July 19, 2020, when the day measured 1.47 milliseconds shorter than normal. The atomic … Read more

Near-Earth asteroid has a surface like a plastic ball pit

Near-Earth asteroid has a surface like a plastic ball pit

During the historic collection event, the sampling head of the OSIRIS-REx spacecraft sank 1.6 feet (0.5 meter) into the surface of the asteroid. Apparently, Bennu’s exterior is made of loosely packed particles that aren’t bound together very securely, based on what happened as the spacecraft collected a sample. If the spacecraft hadn’t fired its thruster … Read more

Tonga eruption blasted 58,000 Olympic pools’ worth of water into the atmosphere, NASA says

Tonga eruption blasted 58,000 Olympic pools' worth of water into the atmosphere, NASA says

When the undersea Hunga Tonga-Hunga Ha’apai volcano erupted on January 15, 40 miles (65 kilometers) north of Tonga’s capital, it created a tsunami as well as a sonic boom that rippled around the world — twice. The eruption sent a tall plume of water vapor into the stratosphere, which is located between 8 and 33 … Read more

Parts of the moon may provide temperatures fit for humans

Parts of the moon may provide temperatures fit for humans

The moon has pits with shaded areas that steadily hover around 63 degrees Fahrenheit (17 degrees Celsius), a temperate range that’s stable for humans, found researchers at the University of California, Los Angeles. The journal Geophysical Research Letters published the study in July. These pit craters, which may potentially lead to caves that could also … Read more

Scientists Reveal The First Images of Atoms ‘Swimming’ in Liquid

Scientists Reveal The First Images of Atoms 'Swimming' in Liquid

The motion of single atoms through liquid has been caught on camera for the first time. Using a sandwich of materials so thin they’re effectively two-dimensional, scientists trapped and observed platinum atoms ‘swimming’ along a surface under different pressures. The results will help us better understand how the presence of liquid alters the behavior of … Read more

Ocean-exploring robot could search for lost cities and shipwrecks

Ocean-exploring robot could search for lost cities and shipwrecks

During a recent moonlit harbor excursion, conversation quickly turned to tales of piracy and exploration. A guide shared stories from the days when tall masts and billowing sails loomed over coastal skylines — and intriguing characters such as Blackbeard and Barbarossa sailed the seas. We couldn’t help but wonder about the secrets that went down … Read more
