What is Tabby's Star? Who Discovered the Ring Nebula? Can Life Survive in TRAPPIST-1?Mysteries abound in astronomy, and not all the questions have answers — yet. Tabby's Star is emblematic of the search for truth. This seemingly ordinary star occasionally undergoes rapid dips and dives in brightness, a phenomenon that Benjamin Montet and discoverer Tabetha Boyajian are still trying to understand. The recent d
- Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists' understanding of the types of planetary systems that exist beyond our own.
- As galaxies age, some of their basic chemical elements can also show signs of aging. This aging process can be seen as certain atoms "put on a little weight," meaning they change into heavier isotopes—atoms with additional neutrons in their nuclei.
