This image from NASA's Spitzer Space Telescope shows the nasty effects of living near a group of massive stars: radiation and winds from the massive stars (white spot in center) are blasting planet-making material away from stars like our sun. The planetary material can be seen as comet-like tails behind three stars near the center of the picture. The tails are pointing away from the massive stellar furnaces that are blowing them outward.The picture is the best example yet of multiple sun-like stars being stripped of their planet-making dust by massive stars.
The sun-like stars are about two to three million years old, an age when planets are thought to be growing out of surrounding disks of dust and gas. Astronomers say the dust being blown from the stars is from their outer disks. This means that any Earth-like planets forming around the sun-like stars would be safe, while outer planets like Uranus might be nothing more than dust in the wind.
This image shows a portion of the W5 star-forming region, located 6,500 light-years away in the constellation Cassiopeia. It is a composite of infrared data from Spitzer's infrared array camera and multiband imaging photometer. Light with a wavelength of 3.5 microns is blue, while light from the dust of 24 microns is orange-red.

Some stars have it tough when it comes to raising planets. A new image from NASA's Spitzer Space Telescope shows one unlucky bunch of stars, born into a dangerous neighborhood. The stars themselves are safe, but the material surrounding them -- the dusty bits of what might have been future planets -- can be seen blowing off into space.
The hazard in this particular nook of space is a group of behemoth stars. Radiation and winds from the massive stars are wiping smaller, sun-like stars clean of their planet-making material.
Many stars and planets do grow up and survive the harsh environments of massive stars. Some astronomers say our middle-aged sun, though now sitting in a tranquil patch of space, once resided in a raucous, massive star-forming cloud. Over time, stars in these turbulent regions disperse and spread out, spending their later years in relative solitude.
The new Spitzer observations illustrate just how nasty these massive star-forming regions can be. It shows a portion of an active star-forming nebula called W5, located about 6,500 light-years away in the constellation Cassiopeia. Radiation and winds from a hub of four stars, each about 20 times as massive as our sun, are stripping the planet-forming material right off of three young, sun-like stars about one light-year away.
The sun-like stars are about two to three million years old -- the age when stars are thought to begin forming planets out of disks of gas and dust that swirl around them. The dust from these disks is visible in the Spitzer image as comet-like tails pointing away from the destructive massive stars.
