Staring up into the night sky, it's easy to be overwhelmed by the seemingly infinite expanse of space, with every pinprick of light in the vast canopy of darkness a star holding secrets forged by 13.8 billion years of the universe's existence. And yet, despite its great age and the unfathomable distance between us and even our nearest neighbor, through the study of astronomy we are able to understand more about the world beyond our atmosphere.
Join our expert writers and editors as we reveal the greatest mysteries in cosmology, such as how black holes form, and explore celestial bodies like exoplanets and nebulas, that are scattered throughout our universe. You will also discover how scientists are pushing the boundaries of space exploration using observatories like the James Webb Space Telescope with the latest astronomy news, features and articles.
