It was thanks to the NASA / ESA Hubble Space Telescope that astronomers have managed to capture this fabulous image of J025157.5 + 600606, a freely floating evaporative gas globule located in the constellation Cassiopeia and shaped like an egg floating in our sight.
Evaporating gas globules (EGGs) are compact pockets of dense interstellar gas within which stars are being born. They are objects that we first identified in the well-known Eagle Nebula in 1995. They are approximately 100 astronomical units wide.
"When a new massive star begins to shine while still within the cold molecular cloud from which it formed, its energetic radiation can ionize the hydrogen in the cloud and create a large hot bubble of ionized gas," the astronomers explained. from Hubble.
"Surprisingly, within this hot gas bubble around a nearby massive star are frEGGs: dark, compact globules of dust and gas, some of which are giving birth to low-mass stars."
The boundary between the cold, dusty frEGG and the hot gas bubble can be seen in the bright purple / blue edges of this fantastic Hubble image.
