description NGC 1555 (Hind's Variable Nebula) Overview
NGC 1555, commonly called Hind's Variable Nebula, is a reflection nebula in the constellation Taurus. It is associated with the young variable star T Tauri, whose changing brightness alters the amount of light illuminating the surrounding dust. John Russell Hind reported the nebula in 1852. Because its visible appearance can change substantially, it is an important example of a variable reflection nebula.
help NGC 1555 (Hind's Variable Nebula) FAQ
What is Hind's Variable Nebula, and what is its catalog number?
Hind's Variable Nebula is the reflection nebula NGC 1555 in the constellation Taurus. John Russell Hind discovered it in 1852.
Why does NGC 1555 change brightness?
Its brightness is linked to the variable young star T Tauri, whose changing light illuminates the surrounding dust. When the illuminating star changes, the reflection nebula can appear to brighten or fade.
Is NGC 1555 an emission nebula or a reflection nebula?
NGC 1555 is classified as a reflection nebula, meaning its visible light is primarily starlight scattered by dust. That differs from an emission nebula, whose gas glows after being energized.
Where should I look for Hind's Variable Nebula?
The nebula is in Taurus near the young star T Tauri. It is a challenging telescopic target because its visibility depends on the star's brightness and the contrast of the surrounding sky.
