A new photo of the Terzan 1 cluster shows that the Hubble Space Telescope is still relevant, even though the James Webb Space Telescope is already revealing new insights into the deepest recesses of the visible universe.
The photo was released by NASA and the European Space Agency and shows a bunch of different colored stars.
The Hubble Space Telescope has a previous view of the Terzan 1 cluster. The 2015 photo was taken using Hubble's Wide Field Planetary Camera 2. The Wide Field Camera 3 captured the new image and the astronauts installed it during the last Hubble servicing mission.
There are the best Hubble Space Telescope images.
The new photo shows a lot more detail than the previous one, showing a bunch of aging stars bound together. A bunch of stars in a spherical shape are called a globular cluster. The stars are so close together that the average distance between them is about one light-year.
The older stars in the Hubble image are red in color, while the younger stars in the photo are not part of the cluster.
The older photo shows stars that were formed during the early stages of the universe. The study of them can help us understand how the universe came to be.
Terzan 1 is a significant local source of X-rays according to the European Space Agency. It is likely that the X-rays come from a system with a dense neutron star and a normal star. When a star runs out of fuel, it leaves behind a remnant called a neutron star. A burst of X-ray emission is caused by the drag of material from the companion star.
Scientists don't know how many black holes are in Terzan 1. Since it is not possible to see a black hole, the best way to detect them is to observe their influence on surrounding stars. The density of stars makes it more difficult to do this.
