Planetary Systems Now Forming in Orion
7.12.1996

How do planets form? Astronomers are finding out by studying one of the most interesting of all astronomical nebulae known, the Great Nebula in Orion. Insets to above mosaic show several planetary systems in formation. The bottom left insert shows the relative size of our own Solar System. The Orion Nebula contains many stellar nurseries.

IC 4406: A Seemingly Square Nebula
27.04.1998

How can a round star make a square nebula? This conundrum came to light with the discovery of planetary nebulae like IC 4406. IC 4406 is most probably cylindrical, with its square appearance the result of our vantage point in viewing the cylinder.

NGC 6164: Dragons Egg Nebula and Halo
26.12.2022

The star at the center created everything. Known as the Dragon's Egg, this star -- a rare, hot, luminous O-type star some 40 times as massive as the Sun -- created not only the complex nebula (NGC 6164) that immediately surrounds it, but also the encompassing blue halo.

A Halo for NGC 6164

The Great Nebula in Orion, also known as M42, is one of the most famous nebulas in the sky. The star forming region's glowing gas clouds and hot young stars are on the right in this sharp and colorful image that includes the bluish reflection nebulae NGC 1977 and friends on the left.

Proplyds: Infant Solar Systems?
17.10.1996

Are planets common in our galaxy? Strong evidence that the answer is "yes" was provided in this 1994 image made by the Hubble Space Telescope . A close-up of the Orion Nebulae, it reveals what seem to be disks of dust and gas surrounding newly formed stars.
