The galaxy NGC 1156 resembles a fragile cherry blossom tree flowering in springtime on this Hubble picture. The various shiny “blooms” throughout the galaxy are the truth is stellar nurseries — areas the place new stars are springing to life. Energetic mild emitted by new child stars in these areas streams outwards and encounters close by pockets of hydrogen gasoline, inflicting the gasoline to glow with a attribute pink hue.
NGC 1156 is situated within the constellation of Aries (the Ram). It’s categorised as a dwarf irregular galaxy, that means that it lacks a transparent spiral or rounded form, as different galaxies have, and is on the smaller facet, albeit with a comparatively giant central area that’s extra densely filled with stars.
Some pockets of gasoline inside NGC 1156 rotate in the wrong way to the remainder of the galaxy, suggesting that there was an in depth encounter with one other galaxy in NGC 1156’s previous. The gravity of this different galaxy — and the turbulent chaos of such an interplay — may have scrambled the doubtless extra orderly rotation of fabric inside NGC 1156, producing the odd habits we see as we speak.
