NLC Taken by Göran Strand on July 24, 2019 @ Tällberg, Sweden
The night before yesterday I saw my first NLC for the season here in Dalarna, Sweden. Now the nights is getting darker even up in the north so we can see these beautiful clouds. Here a photo from that night.
STAR FORMING REGION NGC 3582 WITHOUT STARS Image Credit & Copyright: Andrew Campbell
What's happening in the Statue of Liberty nebula? Bright stars and interesting molecules are forming and being liberated. The complex nebula resides in the star forming region called RCW 57, and besides the iconic monument, to some looks like a flying superhero or a weeping angel. By digitally removing the stars, this image showcases dense knots of dark interstellar dust, fields of glowing hydrogen gas ionized by these stars, and great loops of gas expelled by dying stars. A detailed study of NGC 3576, also known as NGC 3582 and NGC 3584, 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.
