NASA news: Space agency reveals ‘cosmic snowflake’ birthing new stars

An image from NASA‘s Spitzer Space Telescope has revealed a sputtering of new stars forming in the Stellar Snowflake Cluster. The newly formed stars appear as pink and red dots inside the cluster, which spirals outwards resembling a snowflake made of gas and dust, hence the name Stellar Snowflake Cluster. Stars begin to form in clusters as all the gas and dust is condensed, providing the right ingredients.

When they are fully formed, they begin to move away from their birth place.

However, these stars are a “mere” 100,000 years old, and are yet to “crawl” away from their origin.

The Stellar Snowflake Cluster is located inside the Christmas Tree Cluster – aptly named as the gas and dust appears like a Christmas tree – some 2,600 light-years from Earth.

NASA said: “Star-forming clouds like this one are dynamic and evolving structures. Since the stars trace the straight line pattern of spokes of a wheel, scientists believe that these are newborn stars, or ‘protostars.’

“At a mere 100,000 years old, these infant structures have yet to ‘crawl’ away from their location of birth.

“Over time, the natural drifting motions of each star will break this order, and the snowflake design will be no more.

“While most of the visible-light stars that give the Christmas Tree Cluster its name and triangular shape do not shine brightly in Spitzer’s infrared eyes, all of the stars forming from this dusty cloud are considered part of the cluster.

“Like a dusty cosmic finger pointing up to the newborn clusters, Spitzer also illuminates the optically dark and dense Cone Nebula, the tip of which can be seen towards the bottom left corner of the image.”

Hubble can see far into space and is essentially looking back in time as light travels to the craft.

Through Hubble, experts have been able to view the formation of the first galaxies, about one billion years after the Big Bang.

However, as JWST is much more powerful, it will be able to see just 0.3 billion years after the Big Bang to when visible light itself was beginning to form.

JWST will also be situated much farther out in space than Hubble. Hubble is placed in Earth’s orbit just 354,181 miles (570,000 kilometres) from the surface, but JWST will be placed an astonishing 932,056 miles (1.5 million kilometres) from Earth, meaning if it breaks down while it is up there, it will not be able to be fixed.
