Best of Slooh This Week

FEATURED OBSERVATION

TWO ICONIC NEBULAE
Alnitak, the lefthand star of Orion's Belt, provides the energy to illuminate both the Flame Nebula and the background nebulosity to the dark Horsehead Nebula. You can learn more about different types of nebula in the Slooh guides.

HALF A HEART
JanS.2018 is halfway through assembling a huge mosaic of the Heart Nebula. This vast emission nebula has dense dust clouds and distinctive red hydrogen gas energized by hot young stars.
