Hubble takes a picture of the globular cluster Terzan 9

(ORDO NEWS) — This star-studded image shows the globular cluster Terzan 9 in the constellation Sagittarius, heading towards the center of the Milky Way.

The NASA/ESA Hubble Space Telescope captured this sparkling scene with its Wide Field Camera 3 and Advanced Camera for Surveys.

Globular clusters are stable, closely related groups of tens of thousands to millions of stars. As you can see in this image, the hearts of globular clusters are densely filled with stars.

Terzan 9 is studded with so many sparkling stars that it looks like a sea of ​​sparkles or a huge chest of gold.

At the center of the Milky Way is a densely packed group of stars known as the galactic bulge, which is rich in interstellar dust.

This dust makes it difficult to study globular clusters near the center of the galaxy, as it absorbs starlight and can even change the apparent color of the stars in these clusters.

Hubble’s sensitivity in the visible and infrared wavelengths allows astronomers to measure how the color of stars changes due to interstellar dust.

Knowing the true color and brightness of a star allows astronomers to estimate its age and thereby determine the age of a globular cluster.
