Cosmic Buckyballs Could Be Mysterious Infrared Light Source

Scientists may have just traced the source of some of the mysterious infrared emission detected from stars and clouds of interstellar dust and gas. This Unknown Infrared Emission Band (UIE) has baffled scientists for decades; According to a new theoretical work, at least some of these bands could be produced by highly ionized buckminsterfullerene, better known as buckyballs. “I am very honored to have played a part in the extremely complex quantum chemical investigations carried out by Dr Sadjadi that have produced these very exciting results,” said astrophysicist Quentin Parker of the Space Research Laboratory of the University of Hong Kong. “First they looked at the theoretical evidence that Fullerenes – Carbon 60 – can withstand very high ionization rates, and now this work shows the infrared emission signature of the species is a perfect match for some of the most prominent Unknown Infrared Emission features known. This will help re-strengthen this area of ​​research.” Buckminste

This Runaway Star Penetrates Space at More Than 160,000 Kilometers Per Hour

Not all stars enjoy just wandering around, orbiting the galactic center with all the other stars. Some stars go rogue, crossing the Milky Way with significant force. It is a runaway star, and we can trace its trajectory to understand the violent events that could occur in the Universe. One such star, and one of the more famous ones, is Zeta Ophiuchi. Located about 440 light-years from Earth in the equatorial constellation Ophiuchus, it is also one of the strangest stars in the sky. Not only is it incredibly fast, at about 30 to 40 kilometers (roughly 20 to 25 miles) per second, but it’s a strange type of star to see roaring in space. Zeta Ophiuchi is the main sequence star; that is, one that still combines hydrogen into helium in its core. And it’s a hot, massive O-type star: about 20 times the mass of the Sun, glowing blue with intense heat. Such stars also have relatively short lives; Zeta Ophiuchi is about half way past the main sequence’s projected age of 8 million years. Tha
