1. Tour of the Invisible Universe From the Moon to Beyond

2. Powers of Ten

3. The Moon Visible Distance 240,000 miles Taken by Galileo spacecraft in 1990. Infrared Taken during a lunar eclipse Bright spots are warm areas on lunar surface.

4. The Sun Visible Distance 93,000,000 miles Sunspots seen on surface indicating sun rotates every 28 days Infrared and X-Ray Granulation of sun’s surface evidence of convection currents of gas within sun

5. Jupiter Visible Distance 250,000,000 miles Red spot largest known storm in solar system Diameter of red spot twice the size of Earth Radio and X-Ray The bright central region in the left picture is due to radiation from charged particles trapped in Jupiter’s magnetic field

6. Great Nebula in Orion Visible 1,400 light years Cloud of glowing gases, mostly hydrogen Birthplace of stars Infrared and X-Ray The bright yellow region in the lower right of the picture is the Sword of Orion, containing the Great Orion Nebula 1,000 X-Ray emitting young stars

7. Cat’s Eye Nebula Visible Infrared and X-Ray Distance 3,000 light years Planetary nebula associated with dying stars Made of gas cast off by a dying red giant star

8. Crab Nebula Visible Distance 6,500 light years Remnant of massive star look for various colors that arise from different chemical elements in the expanding gas, including hydrogen (orange), nitrogen (red), sulfur (pink), and oxygen (green). Infrared and X-Ray

9. Globular Cluster (M15) Visible Distance 34,000 light years Contains hundreds of thousands of stars All stars about 15 billion years X-Ray 2 neutron star binary systems Never seen before this picture

10. Supernova 1987A Distance: 168,000 LY Visible, Radio & X-Ray images A star destroying itself Colors of X-ray image represent different intensities of X-ray emission

11. M51 (Whirlpool Galaxy) Visible Distance: 37 million light years Spiral galaxy with companion galaxy nearby Infrared Near-IR, Mid-IR, Far-IR The infrared image shows regions of star formation along the galaxy's spiral arms and on either side of the nucleus.
