The Antennae galaxies, 63 million light-years away in the southern constellation Corvus, contain sweeping spiral-like patterns, traced by bright blue star clusters, that show the result of a firestorm of star birth activity which was triggered by the collision of the two orange-colored galaxies.. |
| Three galaxies known as NGC 2300 group are combined with a false-colorX-ray image (magenta) that shows the galaxies immersed in a huge cloud of hot gas about 1.3 million light-years in diameter, with a mass equal to 500 billion times that of the Sun and a temperature of about about 18 million degrees Fahrenheit. | (42 KB) |

At the center of the Crab Nebula lies the Crab Pulsar, measuring only six miles across, but containing more mass than our Sun. As it rotates at a rate of 30 times per second, the Crab Pulsar's powerful magnetic field sweeps around, accelerating particles, and whipping them out into the nebula at speeds close to that of light. |
| NGC 3918, in the constellation Centaurus, is about 3,000 light-years from Earth. It shows a roughly spherical outer envelope but an elongated inner balloon inflated by a fast wind from the hot central star, which is starting to break out of the spherical envelope at the top and bottom of the image. | (46 KB) |

This image of the nearest starburst spiral galaxy, NGC 253, reveals violent star formation within a region 1,000 light-years across. Hubble's high resolution allows astronomers to quantify complex structures, including luminous star clusters, dust lanes which trace regions of dense gas, and filaments of glowing gas. |
| M2-9 is a striking example of a "butterfly" or a bipolar planetary nebula whose gasses stream in opposite directions in excess of 200 miles per second. | (59

The brightest object in this picture is NGC 4881, a 13th-magnitude elliptical galaxy in the outskirts of the Coma Cluster; nearly everything else in this field lies far beyond. There is a fascinating assortment of background galaxies, including an apparent galaxian merger in progress. |
| This image shows one of the most complex planetary nebulae ever seen, NGC 6543, nicknamed the "Cat's Eye Nebula." Hubble reveals surprisingly intricate structures including concentric gas shells, jets of high-speed gas and unusual shock-induced knots of gas. | (38 KB) |

An example of a round planetary nebula, IC 3568 lies in the constellation Camelopardalis at a distance of about 9,000 light-years, and has a diameter of about 0.4 light-years (or about 800 times the diameter of our solar system). |
| This image of the Egg Nebula, located roughly 3,000 light-years from Earth, shows a pair of mysterious "searchlight" beams emerging from a hidden star, criss-crossed by numerous bright arcs. | (45 KB) |
