The 0.6-mile (1-kilometer) wide asteroid, designated " 2019 LF6," orbits the sun entirely inside Earth's orbit, completing one orbit every 151 days. It zooms within the orbit of Mercury (that orbits the sun every 88 days) and swings as far out as Venus (which has a 225-day orbit) in a wonky trajectory that flings it out of the orbital plane, a ...
The term "rare earth" is a misnomer as rare earth metals are actually abundant in the Earth's crust. However, they are rarely found in large, concentrated deposits on their own, but rather among other …
Barry Coleman. Winding through the South Carolina low country, the Cooper River is a reed-lined haven for sportfish and shorebirds. The waterway originates in Berkeley County's Lake Moultrie. From there, it proceeds all the way down to Charleston, where it merges with the Ashley and the Wando to form that city's world-famous harbor.
The majority of rainbows we see look like arches, because they are partly blocked by the ground and horizon.

However, because platinum jewelry is more pure (typically 95 percent platinum versus 58.5 percent gold in 14 kt. gold jewelry) and more dense than gold, it will still cost a bit more than a similar gold ring," she notes. (On October 2, 2023, the price of platinum was $894.05 per ounce. Gold was $1,837 per ounce.)

As we discuss what a nuclear meltdown is, it's also important to talk about what a nuclear meltdown isn't. It's not a nuclear explosion.Nor will any core melt accidents burn a hole through the center of the Earth, as popularized in the 1979 disaster film "The China Syndrome.". In a nuclear meltdown, we're faced with a reactor burning out of …

Millions of years ago, dinosaurs left their tracks in sediment. Typically, the soil was wet -- part of a shoreline, a mudflat or even the bottom of a shallow sea. As the area dried, the tracks hardened. Eventually, another layer of sediment filled the prints, protecting them from erosion or damage. Very heavy dinosaurs could also leave ...

Hydrogen fuel cell kits take this idea one step further. Grove also correctly theorized that you could reverse the process, combining oxygen and hydrogen to release electricity. The result is a hydrogen fuel cell. You can't simply fling the atoms together, though. Hydrogen must be broken down into its positively and negatively charged particles ...
