It was surely one of the best night sky events of this past year. Thanks, Richard! So how about 2025? We can’t predict the next auroral display, but we can provide a preview of 2025’s top stargazing events. Mark your calendars!Best stargazing of 2025: Top events not to miss| EarthSky

A light-year is a way of measuring distance, which doesn't make much sense because "light-year" contains the word "year," which is normally a unit of time. So, how does a light-year measure distance?| HowStuffWorks
View larger. | Graphic representation of deep space communications in our solar system. A new study proposes how to find aliens, or at least their communications. It found that human transmissions are most frequently directed toward spacecrafts near Mars (lower left), as well as the sun and other planets. An alien civilization could most easily detect such transmissions when Mars and Earth are in alignment, from their perspective. And we could use the same principle to search for alien signal...| EarthSky
