The ALMA telescope has been used to find a slowly rotating galaxy. It's the youngest ever found with a measured rotation and it's very slow.

The universe rotates at incredible speeds. The rotation speed of the universe is over 200 kilometers per second. Astronomers don't know how galaxies build up to these speeds The only way to tell is through the measurement of the universe.

A group of astronomer based at Waseda University in Tokyo used ALMA to observe a distant galaxy. It's so far away that it's usually too dim to be seen.

MACS1149-JD1 was magnified by the light passing through a giant galaxy cluster. The astronomer can use this magnification.

Measuring galaxy rotation

When the universe was 500 million years old, it was one of the youngest. O III, or doubly-ionized oxygen, is studied using ALMA.

The model of the size and rotation speed of the disk was created to compare against observations.

Their results were reported in a paper.

MACS1149-JD1 is only 3,000 light-years away. The Milky Way is over 100,000 light-years across. The rotation speed of MACS1149-JD1 is less than a quarter of the Milky Way.

Akio K. Inoue, a co-author of the paper, says that the rotation speed of JD1 is much slower than that of other galaxies and theMilky Way galaxy.

The results show that the universe starts out small and rotates slowly. They accumulate more matter and increase their rotation rate over time.

The team hopes to use the space telescope to conduct further studies of the rotation of the galaxy.
