NASA captures thousands of stars with the Hubble Space Telescope

National Aeronautics and Space Administration (NASA) found a globular cluster with the help of Hubble Space Telescope. It is less than 50,000 light-years from Earth, in the constellation of Ophiuchus (The Serpent). NGC 6355 is a globular cluster of galaxies located in the inner regions of our Milky Way galaxy.

Globular clusters are interconnected groups of millions starswhich can be found in any type of galaxy.

Consistent clustering of stars and their mutual gravitational pull give these clusters an almost spherical shape, with a number of bright stars surrounded by increasingly interstellar separation.

Hubble and the search revolution

With its ability to capture above the distortions of the atmosphere, Hubble has been able to revolutionize the search for globular clusters.

This is because it is not very possible to tell stars apart in globular clusters telescopes terrestrial. But astronomers have achieved this feat by using Hubble to search in more detail for stars in globular clusters.

This Hubble image of NGC 6355 contains data from both Advanced camera for surveys how many wide field camera 3.

In addition, scientists surveying the globular cluster report that this capture will aid in understanding the very exotic elements lurking within the globular cluster, and its group of rapidly spinning neutron stars, or pulsars.

According to the researchers, the cluster is home to more than five pulsars, which are rapidly orbiting neutron stars with magnetic fields four times stronger than Earth’s. a land.

In contrast, pulsars are created when the cores of massive stars cannot resist the gravitational pressure internally. Thus, this situation causes gravitational collapse, which means that neutron stars are made of the densest material in the universe.

Ultimately, scientists believe that pulsars create impressive spin speeds when neutron stars form from binary systems and begin accreting material from a stellar companion.
