It’s not the years…it’s the mileage 🤠
Scientists studying the origins of our galaxy can sometimes feel like they are cosmic archeologists, uncovering the building blocks of our galaxy’s earliest days. One way astronomers can get a better sense of the foundations of our solar system is by observing ancient stellar relics like white dwarf stars, the immensely dense remnants of once-massive stars.
@NASAHubble captured a collection of these galactic monuments 26,000 light-years from Earth. These primordial remains are from stars that formed quickly, at least on a cosmic timescale, in less than 2 billion years. Since we know the location of these white dwarf stars, we can tell how fast and far they move compared to the rest of our galaxy.
