Orion's Babies

This image from NASA's Spitzer Space Telescope shows infant stars "hatching" in the head of the hunter constellation, Orion. Astronomers suspect that shockwaves from a supernova explosion in Orion's head nearly three million years ago may have initiated this newfound birth.
The region featured in this Spitzer image is called Barnard 30, located approximately 1,300 light-years away and sits on the right side of Orion's "head," just north of the massive star Lambda Orionis.
Wisps of green in the cloud are organic molecules called polycyclic aromatic hydrocarbons. These molecules are formed any time carbon-based materials are burned incompletely. On Earth, they can be found in the sooty exhaust from automobile and airplane engines. They also coat the grills where charcoal-broiled meats are cooked.
Tints of orange-red in the cloud are dust particles warmed by the newly forming stars. The reddish-pink dots at the top of the cloud are very young stars embedded in a cocoon of cosmic gas and dust. Blue spots throughout the image are background Milky Way along this line of sight.

Baby Stars

Infant stars glow gloriously in this infrared image of the Serpens Constellation's star-forming region, located approximately 8484 light-years away.
Glowing pink baby stars are embedded in the cosmic cloud of gas and dust that collapsed to create them. Dusty disks of cosmic debris that may eventually form planets surround the stars in this image taken by the Spitzer Space Telescope.

Pistol Nebula

The Pistol Nebula, one of the intrinsically brightest stars in our galaxy, appears as the bright white dot in the center of this image taken with NASA's Hubble Space Telescope. Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) was needed to take the picture, because the star is hidden at the galactic center, behind obscuring dust. NICMOS' infrared vision penetrated the dust to reveal the star, which is glowing with the radiance of 10 million suns.
The image also shows one of the most massive stellar eruptions ever seen in space. The radiant star has enough raw power to blow off two expanding shells (magenta) of gas equal to the mass of several of our suns. The largest shell is so big (4 light-years) it would stretch nearly all the way from our sun to the next nearest star. The outbursts seen by Hubble are estimated to be only 4,000 and 6,000 years old, respectively.
Despite such a tremendous mass loss, astronomers estimate the extraordinary star presently may be 100 times more massive than our Sun, and may have started with as much as 200 solar masses of material, but it is violently shedding much of its mass.
The star is 25,000 light-years away in the direction of the constellation Sagittarius. Despite its great distance, the star would be visible to the naked eye as a modest 4th magnitude object if it were not for the dust between it and the Earth.
This false-color image is a composite of two separately filtered images taken with the NICMOS on Sept. 13, 1997. The field of view is 4.8 light-years across.
