Andromeda Island Universe Image Credit & Copyright : Yuzhe Xiao Explanation : The most distant object easily visible to the unaided eye is M31, the great Andromeda Galaxy some two and a half million light-years away. But without a telescope, even this immense spiral galaxy – spanning over 200,000 light years - appears as a faint, nebulous cloud in the constellation Andromeda. In contrast, a brig..

Young Star Cluster Trumpler 14 from Hubble Image Credit : NASA, ESA, and J. Maíz Apellániz (IoAoA Spain); Acknowledgment : N. Smith (U. Arizona) Explanation : Why does star cluster Trumpler 14 have so many bright stars? Because it is so young. Many cluster stars have formed only in the past 5 million years and are so hot they emit detectable X-rays. In older star clusters, most stars this young ..
