Test your knowledge of the night sky with this edition of TWAN Mystery. In a clear night of late November 2009 TWAN photographer Babak Tafreshi made this single exposure image with a 50-mm lens from high altitude slopes of Himalayas in the Sagarmatha National Park of Nepal, on the trek to Mount Everest base camp. The location was at latitude 28 degrees north and the image looks to the southern horizon in the early morning sky. Try to find out 1- what is the bright star at the right side? 2- What is the notable deep sky object right at the horizon? 3- What has caused the large patchy red glow in the upper part of the image? See more TWAN images of Nepal Himalayas on this gallery.

1.Canopus(Soheil)- in Carina Constellation 2.It's an Open Cluster , NGC2516 , Its very shiny, but It's not in Messier Catalouge. Because Messieh Lived in North hemisphere , and this is a South hemisphere Celestial Body. 3.It should be GUM nebula , But just the south part of it :-D :-D

Hello, I had never see Canopus at the sky, but it's the bright star at the right side of this image. Same for the NGC2516, never see it at the nightsky near to Avior. The big gas around Suhail al Muhlif is an Emission Nebula but don't know what cause it, maybe Vela Pulsar(but it's 5° away) OR Carina Nebula-NGC3372(but it's 24° far) OR caused from some star in NGC2547 .... (?)

1. Conapus 2. NGC 2256 3. Hydrogen rich part of Milky Way

I am too embarrassed to take the test. You guys would publicly humiliate me. . . . Mark


The bright star is Canopus. The deep sky object is that cluster in Carina whose name escapes me...I assume the glow is from the Milky Way as it move3s through Puppis & Carina.

Mohammad Saber Ali Aghaei

Hi! 1- Canopus (α-Carina) 2- NGC 2516 3- I don't know now!
