A Dying Star Blazes Twice as Bright in a Distant Galaxy

Milky Way and Andromeda bypass at 1 million light year separation. At 500,000 light-years, dark matter provides friction that brings galaxies to a close encounter. A 100,000 light-year separation leads to a collision. Credit: NASA/ESA

Andromeda Merger Less Likely Within 5 Billion Years

Ancient Chinese Star Mystery Solved After 600 Years

This simple image illustrates the habitable zone concept. At just the right distance from a star, a terrestrial planet could have liquid water on its surface, a necessary condition for life. New research shows that we should focus our observing efforts on stars with stable habitable zones that remain static for at least 2 billion years. Credit: NASA

Wandering Stars Threaten Solar System Stability

Does life exist on any of these worlds? The Trappist-1 planets have been studied by JWST, which provided important information about their atmospheres. Such studies could help scientists better understand which planetary atmospheres could have chemicals traced back to life. Credit: NASA
