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

Antarctica ice sheet crumbling faster than previously thought, satellite imagery shows

Antarctica ice sheet crumbling faster than previously thought, satellite imagery shows

The first-of-its-kind study, led by researchers at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles and published in the journal Nature, raises new concern about how fast climate change is weakening Antarctica’s floating ice shelves and accelerating the rise of global sea levels. The study’s key finding was that the net loss of Antarctic ice … 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
