In this hands-on experiment, students will investigate the basic principle of photosynthesis and learn how light intensity diminishes as a function of distance from the light source. Questions help learners connect these two ideas to determine if... (View More)

The Hubble Ultra Deep Field lithograph shows the deepest visible light observation of the early universe. In vibrant contrast to the image's rich harvest of classic spiral and elliptical galaxies, there is a zoo of oddball galaxies littering the... (View More)

This image from the Hubble Space Telescope shows light from hot stars eating away the surface of the dust and gas cloud in this region of the Eagle Nebula to reveal a pillar composed of denser material. The text includes information about the... (View More)
