WR 25
69. and
Tr16-244
WR 25 and Tr16-244, at the bottom of the image, are
located within the open cluster Trumpler 16. This cluster
is embedded within the Carina Nebula, an immense
cauldron of gas and dust that lies approximately 7500
light-years from Earth in the constellation of Carina,
the Keel. At the top of the image, a peculiar nebula
with the shape of a “defiant” finger points towards
WR25 and Tr16-244.

Hourglass
70. Nebula
This Hubble image reveals the true shape of MyCn18,
a young planetary nebula located about 8,000 lightyears away, to be an hourglass with an intricate
pattern of ‘etchings’ in its walls.
The results are of great interest because they shed
new light on the poorly understood ejection of stellar
matter which accompanies the slow death of Sunlike stars. In previous ground-based images, MyCn18
appears to be a pair of large outer rings with a smaller
central one, but the fine details cannot be seen.
