The volatile comet, known as 29P/Schwassmann-Wachmann (29P), is around 37 miles (60 kilometers) wide and takes around 14.9 years to orbit the sun. 29P is believed to be the most volcanically active comet in the solar system.

Negro) Thousands of years ago, children from the Iberian Peninsula carved pieces of slate into the shape of owls, creating palm-sized toys to play with, a new study suggests. Originally, archaeologists thought the cartoonlike figures were sacred objects representing deities, used only in rituals. But a new study reveals that they also could have served as children's toys or amulets.

Shingles, or herpes zoster, is caused by the varicella-zoster virus, the same pathogen that causes chickenpox. After a chickenpox infection, the virus becomes dormant and hides in specific nerves. The virus can later be "reactivated" and cause shingles, which causes painful rashes of fluid-filled blisters.

It turns out, the cough was triggered by a nearly 7-inch-long (17.2 centimeters) mass pushing against his right lung. According to a description of the case, published Oct. 30 in the Journal of Surgical Case Reports, the 22-year-old man had no notable medical history or history of smoking, and he tested negative for COVID-19 in the emergency room.

The colossal explosion was similar to the asteroid impact on Earth that wiped out the nonavian dinosaurs, a new study shows.

This predator belonged to a different lineage of theropods — bipedal and mostly meat-eating dinosaurs — than the one that produced modern birds, but its body shape and limbs hint that it swam and dove as a penguin does, scientists recently discovered.
