Our sun is on a long, strange trip to its eventual demise.

There are billions more just like it in the galaxy at large. If this star was almost any

To see exoplanets, NASA’s Roman Space Telescope will throw shade on stars NASA’s newest major observatory will include the most advanced planet-imaging tech ever flown in space. Here’s how it works When you’re looking for exoplanets, stars are irritating. Now, I have nothing against stars! I live near one and have deep appreciation for the light it provides. Stars are interesting scientifically and also happen to be very pretty. And, certainly, they’re necessary. Planets form around stars, and t
