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 loops of gas expelled by dying stars.
A detailed study of NGC 3582, also known as
NGC 3584 and
NGC 3576,
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.
The
above image was taken at the Desert Hollow Observatory north of
Phoenix,
Arizona,
USA.
