Explanation:
This treasure chest is full
of stars.
The featured
image was obtained with NASA's James
Webb Space Telescope and shows a dust
pilar in the Carina Nebula
inside our Galaxy,
roughly 7500 light-years away.
It is formed by interstellar
gas and dust,
and shaped by powerful stellar
winds and radiation form neighboring stars like the nearby Eta
Carinae stellar system which is more luminous than 5 million suns.
The star formation inside the pillar is excavating its head, creating the open
lid of the chest.
Astronomers estimate that there are about 70 stars in a compact
cluster inside the pillar.
This cluster is now thought to be only around 1.3
million years old.
Its bounty of young stars includes a massive star approximately 19 times as massive
as the Sun.
More massive stars are
rarer, shine brighter and evolve faster than less massive stars.
They are the shiniest jewels in the treasure chest.
