Horseshoe Nebula (Barnard's 143)
| Barnard's 143 is a dark nebula in the constellation of the Eagle. The darks nebulae are very dense regions of gas and dust that hide the stars that are behind them! I named it “Horseshoe” from its shape that resembles the petals which placed on the horses' hooves |
