Webb learns a lesson from a new, beautiful picture taken by the Hubble Space Telescope.
Even though the James Webb Space Telescope is finding out new things about the invisible universe. A new picture of the Terzan 1 cluster taken by the Hubble Space Telescope shows that it is still very useful.
In a picture released on October 10 by NASA and the European Space Agency (ESA), which are in charge of the expedition together, you can see a globular cluster 22,000 light-years from Earth in amazing detail.
NASA previously released a 2015 image of the Terzan 1 cluster from the Hubble Space Telescope. The Wide Field Planetary Camera 2 on Hubble took the picture in 2015, and it was still working until 2009.
During the last Hubble service mission, astronauts carried the Wide Field Camera 3 with them. This camera was able to take the picture. This instrument has a much higher resolution than the one it replaced.
Compared to previous images, the new one provides a much clearer look at the globular cluster’s depth, revealing a plethora of red, aging stars held together by mutual gravity. A globular cluster is a dense group of tens of thousands of stars that is roughly the shape of a sphere.
stars typically have a separation of about one light year from one another
Due to their close proximity, stars typically have a separation of about one light year from one another. OR about a quarter of the distance between the Sun and Proxima Centauri.
Some of the oldest stars in our galaxy can be found in these clusters, which is why they look red in the Hubble image. The blue stars, on the other hand, are younger foreground stars that aren’t actually part of the cluster but add visual interest.
The European Space Agency said in 2015. “The ages of stars in galaxy clusters show that they formed during the earliest stages of galaxy formation.” We can also learn more about galaxy formation by examining them.
According to ESA, globular clusters like Terzan 1 are a major domestic source of X-rays. People think that the sources of these X-rays are binary star systems made up of a dense neutron star and a regular star.
When a star like our sun explodes, it runs out of fuel. The dense core that remains is a neutron star. X-ray bursts occur as a neutron star pulls material from its companion star.
No one knows for sure how many black holes of stellar or intermediate mass are hiding in globular clusters like Terzan 1. Since black holes absorb light rather than emit it, the best way for a telescope to detect them is by observing the gravitational influence they have on nearby stars rather than directly observing the black holes themselves. Because there are so many stars in a globular cluster, this is unfortunately a much harder job to do.
