The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be […]

Search for Hidden Cosmic Companions in Sun’s Backyard

Some stars have planets. Others are orbited by brown dwarfs, balls of gas too massive to be planets, but too low-mass to be stars. Astronomers love these brown dwarf-star pairs because being paired with a star helps reveal a brown dwarf’s age. Ages of astronomical objects are often hard to measure, but essential for understanding […]
