Leonid meteor shower 2021: when to see the most shot stars

The Leonid Meteor shower will peak in the early morning hours on November 17th. The meteor shower is known for a storm every 33 years, with the last storm occurring in 2002, NASA said. Its meteor debris originates from Comet 55P / Tempel-Tuttle, a small comet about 2.24 miles (3.6 kilometers) wide, according to NASA. The comet travels through space …

New material could be two superconductors in one

Aravind Devarakonda PhD ’21 is the lead author of a paper describing an exotic form of superconductivity. Credit: Dennis Paist MIT Physicists and colleagues have demonstrated an exotic form of superconductivity in a new material that the team synthesized only a year ago. Although predicted in the 1960s, until now this type of superconductivity has been proven difficult to stabilize. …

The longest lunar eclipse in centuries will happen this week, NASA says

Credit: CC0 Public Domain You can see the longest partial lunar eclipse in hundreds of years the week. The “almost complete” lunar eclipse is expected overnight Thursday, Nov. 18, to Friday, Nov. 19, NASA said. “The moon will be so close to orbiting the sun on November 19 that it will pass through the southern part of the earth’s shadow …

A 1980s space telescope could have seen Planet Nine

In 1983, astronomer Michael Raven-Robinson conducted a search for a proposed 10th planet (Pluto was then still a planet) with the data of the infrared astronomical satellite, the first infrared space telescope. Rowan-Robinson did not create a new planet, and in 1991 he was convinced that such a planet did not exist, at least not in the region of the …

Nanoscale ‘computer’ controls functions of protein, influences cell behavior

Researchers have created a transistor-like ‘logic gate’, which is a type of computational operation in which multiple inputs control a result, and embedded it into a protein. They found that not only could they rapidly activate the protein using light and the drug rapamycin, but also that the activation resulted in the cells undergoing internal changes that enhanced their adhesive …

Where does gold come from?

Neutron-rich material is ejected from the disk, which allows the rapid neutron-capture process (R-Process). The light blue area is a special fast ejection of substance, called a jet, which typically originates parallel to the disk’s rotation axis. Credit: National Radio Astronomy Observatory How are chemical elements formed in our universe? Where do heavy elements like gold and uranium come from? …
