NASA wishes Diwali by sharing ‘festival of celestial lights’ image captured by Hubble. see picture

NASA has wished Diwali to everyone celebrating the festival by sharing an image of the globular cluster taken by the Hubble Space Telescope on social media. The space agency has called the globular cluster a “celestial celebration of lights.” The globular cluster is located near the center of the Milky Way galaxy, 30,000 light years from Earth.

A globular cluster is a stable, tightly bound group of thousands to millions of stars, and is associated with all types of galaxies.

The globular cluster is Liller 1, and consists of tightly bound blue stars. Hubble’s Wide Field Camera 3 (WFC3) captured this image with precision because the instrument is sensitive to wavelengths of light that the human eye cannot detect.

Liller 1 is located within the galaxy’s ‘bulge’, which refers to the dense and dusty region at the center of the galaxy.

As a result, interstellar dust has largely obscured Earth’s view of Lilar 1. Interstellar dust scatters visible light, especially blue light, quite effectively.

However, infrared and red visible light can pass through dusty areas, and since WFC3 is sensitive to both visible and near-infrared wavelengths, the instrument is able to see through dust clouds.

Liller 1 is a unique globular cluster because it contains a mix of very young and very old stars. This makes Liller 1 interesting because most globular clusters contain only old stars, some of which are as old as the universe.

Lilar 1 consists of two distinct stellar populations of different ages, the youngest population being one to two billion years old, and the oldest population being 12 billion years old.

This means that Lular 1 was formed over an exceptionally long period of time, according to NASA.
