Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Explanation:
Most galaxies don't have any rings -- why does this galaxy have two? To begin, the bright band near NGC 1512's center is a nuclear ring, a ring that surrounds the galaxy center and glows brightly with recently formed stars. Most stars and accompanying gas and dust, however, orbit the galactic center in a ring much further out -- here seen near the image edge. This ring is called, counter-intuitively, the inner ring. If you look closely, you will see this the inner ring connects ends of a diffuse central bar that runs horizontally across the galaxy. These ring structures are thought to be caused by NGC 1512's own asymmetries in a drawn-out process called secular evolution. The gravity of these galaxy asymmetries, including the bar of stars, cause gas and dust to fall from the inner ring to the nuclear ring, enhancing this ring's rate of star formation. Some spiral galaxies also have a third ring -- an outer ring that circles the galaxy even further out.

Simon says, "This is a photograph not a picture."
This is fantastic photograph of a picturesque galaxy made by a photographer using photography and I would hang it on a wall as either a photograph or a painted picture.

I see this on my cell phone. The explanation overlaps the title, making it difficult to read. Shorter explanation in the future please. I subscribed.

We are not alone...
The Orion Nebula 👽

Dude whatever the star is in the picture it looks huge

Possibly a new earth in their their own Milky Way being created.

Perhaps the galactic core of this spiral galaxy exploded, driving most of it's mass out to form the outer ring.
Then the remaining mass recoalesced, forming another spiral galaxy structure.
Note the stars in the inner ring are bright blue, indicating that they are hot new stars, forming from accreting infalling material.
