Glitch in neutron star reveals its hidden secrets

neutron stars

Neutron stars are not only the most dense objects in the Universe, but they rotate very fast and regularly. Until they don't.Occasionally these neutron stars start to spin faster, caused by portions of the inside of the star moving outwards. It's called a "glitch" and it provides astronomers a brief

‘Oumuamua is not an alien spacecraft: study

In this artist's concept, the interstellar object 'Oumuamua is depicted as a cigar-shaped body. A new analysis strongly suggests that 'Oumuamua has a natural origin and is not an alien spacecraft.

On October 19, 2017, astronomers discovered the first known interstellar object to visit our solar system. First spotted by the Panoramic Survey Telescope and Rapid Response System 1 (PanSTARRS1) telescope located at the University of Hawaii's Haleakala Observatory, the object defied easy description, simultaneously displaying characteristics of both a comet
