    Comet Hale-Bopp Long Island Sound

    Comet Hale-Bopp was one of the brightest comets in decades, reaching its closest approach to Earth in 1997. It could be seen across the Northern Hemisphere, and it was visible without a telescope or binoculars for about 18 months. The white tail is due to sunlight reflecting off dust from the comet, and traces the motion of the comet. The blue tail shines as gas from the comet, primarily carbon monoxide, interacts with particles flowing away from by the Sun, and traces the direction of this flow. Here, Comet Hale-Bopp is captured as it appears over the waters of Long Island Sound in New York.

    The Milky Way Hawaii, US

    The Milky Way is our home galaxy. It contains billions of stars, of which our Sun is just one. The Milky Way is shaped like a large disk, with a bulge at the middle that contains a giant black hole. Our Sun, and the planets that orbit it including Earth, are about two-thirds away from the center of this galactic disk. From this vantage point, the combined light from the multitude of other stars in our Galaxy produce a milky path, which may be how the name originated. The dark patches are due to interstellar dust that obscures the view to the center of the Galaxy in visible light, making it necessary to use telescopes sensitive to other wavelengths to study the Galactic center. The Milky Way is just one of billions of known galaxies, each containing their own multitude of pinpricks of starlight.

    Rainbow Lands On Cow New Zealand

    Sunlight is made up of a mixture of many wavelengths of light. Each visible wavelength is perceived as a different color, with violet having the shortest wavelength, and red the longest. When sunlight enters a raindrop, its path is bent; the light is "refracted." Each wavelength is bent slightly differently, with shorter wavelengths bent more than longer ones. This rainbow is caused by light being refracted (bent) when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it. This causes the combined colors of sunlight to spread out into the familiar red, orange, yellow, green, blue, indigo, and violet of a rainbow. Here we see a rainbow as it appears to touch down over a cow in New Zealand.

    Lights Over Dublin Wales, UK & Dublin, Ireland

    For centuries, lighthouses have served an important role: they have kept mariners and other seafarers safe. By illuminating rough stretches of water through their powerful beacons of light, they help prevent nautical accidents. Lighthouses also serve as bright artificial beacons that allow navigators to guide their ships home. This image of a lighthouse off the west coast of Wales has additional beautiful illuminated elements. From the top left to the lower right in the sky, Venus, Jupiter, and the Moon— reflecting light from the Sun— can be seen hanging over Dublin, Ireland.
