Star cluster
ASCC 114
Open star cluster · 56 million years
An open cluster of stars born together from the same gas cloud in the Milky Way’s disc; the Galaxy’s tidal forces will disperse it within a few hundred million years. Position, distance, age and member count come from the MWSC catalogue; the total brightness is roughly estimated from the member count.

Light's journey
The light you see tonight set out around the year 102. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 34 million years.
