    Bioluminescence in the Gippsland Lakes Victoria, Australia

    Bioluminescence is light produced by a chemical reaction inside a living organism. There are many bioluminescent life forms on land, including different kinds of fungus and insects. Most bioluminescence, however, occurs in water, particularly in in the depths of Earth's oceans where sunlight cannot reach. Here we see the bioluminescent glow of marine plankton in the Gippsland Lakes in southeastern Australia. Above, the spectacular light of the Milky Way and star trails from a long exposure are also visible.

  • iyl_16_Transit of Venus 2407 BPC_720

    Venus In Transit

    On June 6, 2012, photographer Phil Hart captured this photograph of the shadow of the planet Venus on the face of the Sun as it rose behind a communication tower in Leipzig, Germany. This so-called transit occurred when the orbits of Venus and Earth lined up just right so that Venus passed between Earth and the Sun, casting a shadow. By observing the transit of Venus from two widely separated distances on Earth, astronomers were able to determine the distances of Venus and Earth from the Sun, and the size of the solar system. Measurements using radar are now used to make more accurate measurements of solar system distances, but observing transits of exoplanets (planets outside our solar system) around their parent stars can provide valuable information about these objects.

    Lunar Eclipse 1.25 light seconds

    When the Moon passes through the shadow of the Earth, a lunar eclipse occurs. During such an event, light from the Sun still reaches the Moon. However, before sunlight reaches the Moon, it must pass through dense layers of the Earth's atmosphere. When this happens, the light is scattered by molecules of air and other small particles in the atmosphere. The shorter, or bluer, wavelengths of light are more affected by this, so mainly only the red part of sunlight reaches the Moon. This is why the Moon appears to be orange or red during a lunar eclipse. This multiple-exposure image was taken during a lunar eclipse on July 16, 2000.

  • m16

    M16/Eagle Nebula 6500 light years

    Ultraviolet light from a group of young, massive stars is blasting and sculpting clouds of gas and dust that contain stars being born deep inside. This region was made famous from the release of a Hubble image in 1995 that became known as the “Pillars of Creation.” This new version of the image, also known as M16, takes advantage of Hubble's upgraded instrumentation, allowing an even more spectacular view. In this image of ultraviolet and visible light, oxygen emission is blue, sulfur is orange, and hydrogen and nitrogen are green.

  • m51

    M51 30 million light years

    By combining light from several different telescopes, this image reveals information about the galaxy known as M51, which could never be gleaned from just one band of light. NASA’s Chandra finds point-like X-ray sources (represented in purple) that are black holes and neutron stars in binary star systems, along with a diffuse glow of hot gas. Visible light data from Hubble (green) and infrared data Spitzer (red) both highlight long lanes of stars and gas laced with dust. A view of M51 with GALEX shows hot, young stars that produce lots of ultraviolet light (blue).
