Artwork • February 7th, 2019

Artwork showing a pair of white dwarfs in orbit around each other with an accretion disk. This illustrates what happens when one star begins to siphon material off its partner. The white dwarf stars are similar in size to earth but they are 200,000 times more dense. ZTF is well-suited to detect binary star systems like this one.
