The Chandra X-ray Telescope took this image of thousands of stars crowded together at the center of the Milky Way. Within them is the massive black hole Sagittarius A*.

NGC290 The star cluster NGC290 is within the Smali Magellanie Cloud, one of the closest galaxies to us.

Its hundreds of young stars were created from the same Cloud of gas and dust.

Cat’s Eye Nebula Rings of materiał surround the remains of a dying star. These dust shells were created as the star pushed away its outer layers.

Saturn When Saturn is seen in infrared light, detail in its upper atmosphere is revealed. Blue indicates a elear view of the main cloud layer; green and yellow are thick and thin haze respectively; orange denotes high clouds.

Eagle Nebula This column of gas and dust, several light-years long, is just a smali part of a huge star-forming region, the Eagle Nebula. Bumps in the column are dense regions where stars are taking shape.

Stephan’s Ouintet These five galaxies are known as Stephan’s Ouintet, but only four are close; the white one is unrelated.

Helix Nebula This false-color infrared Spitzer Telescope image shows the red remains of a star once similar to the Sun. The blue materiał was thrown off by the star thousands of years ago.

Heat of the Big Bang The COBE (Cosmic Background Explorer) satellite was the first to make this type of image of the sky. It shows the heat remaining after the Big Bang that marked the start of the universe.
