Star Forming Region NGC 3582
Explanation: What's happening in the NGC 3582 nebula?
Bright stars
and
interesting molecules
are forming. The
complex nebula
resides in the star forming region called RCW 57. Visible in
this image
are dense knots of
dark interstellar dust
, bright stars that have formed in the past few million years, fields of
glowing hydrogen gas
ionized by these stars, and
great loop
s of gas expelled by dying stars. A
recent detailed study of NGC 3582
uncovered at least 33 massive stars in the end stages of formation, and the clear presence of the complex carbon molecules known as
polycyclic aromatic hydrocarbons
(PAHs). PAHs are thought to be created in the cooling gas of star forming regions, and their development in the Sun's formation nebula five billion years ago may have been an important step in the
development of life
on Earth.
This picture
was taken last year with the
Blanco 4-meter telescope
at the
Cerro Tololo Inter-American Observatory
(CTIO), in
Chile
