Strange 'Elephant Trunk' Space Clouds Surround Star Cluster (Video)
A telescope in Chile has captured the most detailed views ever of odd clouds of interstellar dust that are being sculpted into strange shapes by the wind from nearby stars.
Astronomers used the European Southern Observatory's La Silla Observatory to capture the amazing new images of the space clouds around the distant star cluster NGC 3572. The new photo shows a mysterious ring and structures known as "elephant trunks" — huge columns of interstellar dust and gas.

"This new image shows how these clouds of gas and dust have been sculpted into whimsical bubbles, arcs and the odd features known as elephant trunks by the stellar winds flowing from this gathering of hot young stars," ESO officials wrote in an image description.
NGC 3572 — located in the southern constellation Carina — plays host to many young, hot stars that shine bright blue and white in the new photos and shape the clouds, ESO officials wrote.
The "Pillars of Creation" photo of the Eagle Nebula taken by NASA's Hubble Space Telescope is the most famous example of elephant trunks, according to ESO representatives.
Another interesting aspect of the new image is a ring-shaped nebula located a bit above the center of the picture. Scientists aren't sure what the origin of the nebula is, but they think it might be a leftover from the cloud of material that formed the star cluster, or it could be a bubble around a hot star. Some astronomers also suggest that it could be a planetary nebula — the remains of a dying sunlike star.
Stars in clusters might have formed at around the same time, but they are incredibly diverse in size, temperature, color and mass, ESO officials said.
"These gangs of young stars stick together for a relatively short time, typically tens or hundreds of millions of years," ESO officials said. "They are gradually disbanded by gravitational interactions, but also because the most massive stars are short-lived, burning through their fuel quickly and ultimately ending their lives in violent supernova explosions, thus contributing to the dispersion of the remaining gas and stars in the cluster."
