Here’s a Picture of the Birth of a Star from the Hubble Telescope

The Hubble mission has given us more images than we could possibly ever list here.

From NASA/Hubble: Galaxies are well known as the birthplaces of stars and planets thanks to the overwhelmingly large amount of dust and gas within them. Over time, cold gas coalesces into molecular clouds, leading to the further emergence of star-forming regions. This image taken with the NASA/ESA Hubble Space Telescope depicts a fantastic new class of star-forming nursery, known as Free-floating Evaporating Gaseous Globules, or frEGGs for short. This object, known as J025027.7+600849, is located in the constellation of Cassiopeia. When a massive new star (or stars) starts to shine while still within the cool molecular cloud from which it formed, its energetic radiation can ionise the cloud’s hydrogen and create a large, hot bubble of ionised gas. Amazingly, located within this bubble of hot gas around a nearby massive star are the frEGGs: dark compact globules of dust and gas, some of which are also giving birth to low-mass stars. The boundary between the cool, dusty frEGG and hot gas bubble is seen as the glowing purple/blue edges in this fascinating image. Learning more about these odd objects can help astronomers understand how stars like our Sun form under external influences. In fact, our Sun may have even been born in a frEGG!

And what’s amazing about each of them is how much they tell us about outer space – in addition to showing us how little we actually know.

The photo we’re bringing you today shows nothing less than a star being created.

Or, as Science Alert describes, “Stars in the large clouds of stellar nurseries are formed from cool clumps of dense molecular hydrogen that collapse under their own gravity, so stars are born nestled in thick, molecular clouds.

When a very massive, hot star starts to shine, their intense ultraviolet radiation ionises their birth cloud, creating a large, hot bubble of ionised gas called a Strömgren sphere.”

The NASA/Hubble took a picture of just such a nursery.

As for what we’re seeing in this picture exactly, NASA tries to break it down for those of us who aren’t well-versed in astronomy.

“When a massive new star (or stars) starts to shine while still within the cool molecular cloud from which it formed, its energetic radiation can ionise the cloud’s hydrogen and create a large, hot bubble of ionised gas.
