ESO Image: Lupus 4 - Cosmic Spider Swallows Starlight

A dark, spider-shaped cloud of cosmic gas blocks out light from stars in a new image taken by a telescope in the Southern Hemisphere.

The amazing photo, taken by a telescope at the European Southern Observatory's La Silla Observatory in Chile, is filled with stars glowing brightly in a variety of colours.

Red, blue, yellow and orange stars frame the gas blob called Lupus 4, which blots out light from other, more distant stars in the center of the image. Fly through the image in a new video of the Lupus 4 space cloud from ESO.

Eventually, Lupus 4, which is located about 400 light-years from Earth, could give birth to its own stars.

"How many stars might eventually start to shine within Lupus 4? It is hard to say, as mass estimates for Lupus 4 vary," ESO representatives said in a statement today (Sept. 3).

"Two studies agree on a figure of around 250 times the mass of the sun, though another, using a different method, arrives at a figure of around 1,600 solar masses."

"Either way, the cloud contains ample material to give rise to plenty of bright new stars."

"Rather as earthly clouds make way for sunshine, so, too, shall this cosmic dark cloud eventually dissipate and give way to brilliant starlight."

Another gas cloud in the same area, called Lupus 3, already hosts about 40 young stars that formed over the course of the last 3 million years, ESO said.

The spidery cloud is part of a loose star cluster named the Scorpius-Centaurus OB association, which is a young, widely dispersed star grouping, according to ESO.

The stars in the cluster also likely come from the same huge cloud of cosmic material, representatives from the astronomy organization added.
