The Egg Nebula, located around 1,000 light years away, is home to a dying star entering last phase of its life.

At the center of the Egg Nebula is its yolk: a deteriorating sun-like star.

Hubble’s latest image reveals a young pre planetary nebula where a dying star expels dust and light. Why does this brief phase matter so much for understanding stellar evolution?

A vast underground tunnel known as a lava tube, formed from ancient volcanic activity, was recently discovered lurking beneath Venus.
