Did the Helix Nebula catch your eye? 👁️
All eyes are on this eerie Spitzer Space telescope image that shows infrared radiation from the well-studied Helix Nebula, a mere 700 light-years away in the constellation Aquarius.
The two-light-year diameter shroud of dust and gas around a central white dwarf, is an example of a planetary nebula, one of the final stages in the evolution of a Sun-like star. The dust makes this cosmic eye gleam red.
The nebular material was ejected from the star many thousands of years ago, the close-in dust could be generated by collisions in a reservoir of objects, like our own solar system’s Kuiper Belt or cometary Oort cloud. Formed in the distant planetary system, the comet-like bodies have otherwise survived the dramatic late stages of the star’s evolution.
Keep an eye out as we highlight some of our favorite nebulae this November! 👀
