In one of the brightest parts of Milky
Way lies a nebula where some of the oddest things occur.
NGC 3372, known as the Great
Nebula in Carina, is home to massive stars and changing
the most energetic star in the nebula, was one of the brightest stars
in the sky in the 1830s, but then faded dramatically. The Keyhole
Nebula, visible left the center, houses several of the most
massive stars known and has also changed its appearance. The entire Carina
Nebula spans over 300 light
years and lies about 7,500 light-years away in the constellation
of Carina. Pictured
above is the most detailed image
of the Carina Nebula ever taken. The controlled
is a composite of 48 high-resolution frames taken by the Hubble Space
Telescope and released to honor its 17th anniversary.
