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.

Shining Starlight On The Dark Cocoons Of Star Birth

This series of images from NASA's Spitzer Space Telescope shows a dark mass of gas and dust, called a core, where new stars and planets will likely spring up.


The image on the far right shows the core as seen at longer wavelengths of infrared light (8 microns); when viewed at this wavelength, the core appears dark. The middle image shows the core as seen at a shorter infrared wavelength (3.6 microns).


In this view, the core lights up because it is deflecting starlight from nearby stars. This unexpected light, called coreshine, tells astronomers that the dust making up the core must be bigger than previously thought - smaller particles would not have been big enough to scatter the light. The image on the left is a combination of the other two images.


This particular core lies deep within a larger dark cloud called L183. Spitzer's infrared vision allows it to peer into the dark cloud to see the even darker cores buried inside. The observations were made with Spitzer's infrared array camera. Image credit: NASA/JPL-Caltech/Observatoire de Paris/CNRS
