Tour of the Invisible Universe From the Moon to Beyond
The Moon Visible Infrared Taken during a lunar eclipse Bright spots are warm areas on lunar surface. • Distance 240,000 miles • Taken by Galileo spacecraft in 1990.
The Sun Visible Infrared and X-Ray Granulation of sun’s surface evidence of convection currents of gas within sun • Distance 93,000,000 miles • Sunspots seen on surface indicating sun rotates every 28 days
Jupiter Visible 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 • Distance 250,000,000 miles • Red spot largest known storm in solar system • Diameter of red spot twice the size of Earth
Great Nebula in Orion Visible 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 • 1,400 light years • Cloud of glowing gases, mostly hydrogen • Birthplace of stars
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
Crab Nebula Visible Infrared and X-Ray • 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).
Globular Cluster (M15) Visible X-Ray 2 neutron star binary systems Never seen before this picture • Distance 34,000 light years • Contains hundreds of thousands of stars • All stars about 15 billion years
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
M51 (Whirlpool Galaxy) Visible 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. • Distance: 37 million light years • Spiral galaxy with companion galaxy nearby
