A new image from the Hubble Space Telescope shows a cosmic cloudscape, with clouds of dust and gas swirling in beautiful colors.
This gorgeous new image from the Hubble Space Telescope shows something once considered little more than an annoyance: cosmic dust. For many years, astronomers thought of dust as a problem which blocked out important objects from view, but in recent decades they have learned about dust’s importance in forming stars and planets, and even making new molecules in space.
The image shows clouds of dust and gas located near the Tarantula Nebula, a place also renowned for its beauty. It is part of a satellite galaxy of the Milky Way called the Large Magellanic Cloud, located 160,000 light-years away and a hotbed of star formation.The star formation in this region is spurred on by the presence of dust, which clumps together and attracts more particles due to gravity, eventually building up the cores which go on to form planets or stars.

Cosmic dust is often comprised of carbon or of molecules called silicates, which contain silicon and oxygen.”

By combining data from visible light telescopes like Hubble and infrared telescopes like Webb, scientists are able to see both the dusty objects which exist throughout our galaxy and beyond, and the interior structures which would otherwise be blocked from view by the dust.
