NASA Extends Diwali Wishes By Sharing Image Of A ‘Celestial Festival Of Lights’ Captured By Hubble. See PIC

<p><span style="font-weight: 400;">NASA has extended Diwali wishes to everyone who celebrates the festival by sharing on social media an image of a globular cluster captured by the Hubble Space Telescope. The space agency has called the globular cluster a &ldquo;celestial festival of lights&rdquo;. The globular cluster is located 30,000 light years away from Earth, near the centre of the Milky Way galaxy.</span></p> <p><span style="font-weight: 400;">A globular cluster is a stable, tightly bound cluster of tens of thousands to millions of stars, and are associated with all types of galaxies.</span></p> <figure class="image"><img src="https://ift.tt/KTIgewc" alt="A globular cluster captured by NASA's Hubble Space Telescope.

Hubble's Wide Field Camera 3 (WFC3) captured this image with precision because the instrument is sensitive to wavelengths of light the human eye cannot detect.</span></p> <p><strong>MUST READ |&nbsp;<a title="Science For Everyone: Why Delhi Air Pollution Is So Severe, And What Needs To Be Done" href="https://ift.tt/qGkewnW" target="_self">Science For Everyone: Why Delhi Air Pollution Is So Severe, And What Needs To Be Done</a></strong></p> <p><span style="font-weight: 400;">Liller 1 is located within the Milky Way's 'bulge', which refers to the dense and dusty region at the centre of the galaxy.&nbsp;&nbsp;</span></p> <p><span style="font-weight: 400;">As a result, interstellar dust has heavily obscured Earth's view of Liller 1. Interstellar dust scatters visible light, especially blue light, quite effectively.&nbsp;</span></p> <p><strong>MUST READ |&nbsp;<a title="Delhi Air Pollution: How Outdoor And Indoor Air Pollution Affect Male And Female Reproductive Health" href="https://ift.tt/3EjZBuh" target="_self">Delhi Air Pollution: How Outdoor And Indoor Air Pollution Affect Male And Female Reproductive Health</a></strong></p> <p><span style="font-weight: 400;">However, infrared and red visible light can pass through the dusty regions, and since WFC3 is sensitive to both visible and near-infrared wavelengths, the instrument has been able to see through the clouds of dust.</span></p> <p><span style="font-weight: 400;">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 have only old stars, some of which are as old as the universe.</span></p> <p><strong>MUST READ |&nbsp;<a title="How Are Planets Made?
