A waterfall is usually a geological formation resulting from water, often in the form of a stream flowing over an erosion-resistant rock formation that forms a sudden break in elevation. Waterfalls may also be artificial, and they are sometimes used for garden and landscape ornaments. Some waterfalls form in mountain environments where erosion is rapid and stream courses may be subject to sudden and catastrophic change. Photo credit: Diliff Archive - Nominate new image

The Plumed Basilisk (Basiliscus plumifrons) is a species of lizard native to Latin America. Its natural range covers a swath from Mexico to Ecuador . Plumed basilisks are opossums and snakes . Plumed Basilisks are noted for a remarkable ability to, in an attempt to evade possible threats, run across bodies of water using their extremely fast-moving, large, webbed feet.

A TRACE image of sunspots on the surface, or photosphere, of the sun from September 2002, is taken in the far ultraviolet on a relatively quiet day for solar activity. However, the image still shows a large sunspot group visible as a bright area near the horizon. Although sunspots are relatively cool regions on the surface of the sun, the bright glowing gas flowing around the sunspots have a temperature of over one million °C (1.8 million °F). The high temperatures are thought to be related to the rapidly changing magnetic field loops that channel solar plasma. Photo credit: NASA/TRACE Archive - Nominate new image

Monarch butterflies are especially noted for their massive southward migrations from August through October. Female Monarch butterflies deposit eggs for the next generation during these migrations. The population east of the Rocky Mountains overwinters in Michoacán, Mexico, and the western population overwinters in various sites in central coastal California. The length of these journeys far exceeds the lifetime of any given butterfly. How the species manages to return to the same overwintering spots over a gap of several generations is still subject of research. Photo credit: drumguy8800 Archive - Nominate new image

The Eiffel Tower in Paris is one of the world's most recognizable buildings and a symbol of France. The 300 m (986 ft) high tower was designed by Gustave Eiffel as a gateway to the Exposition Universelle of 1889. It was the world's tallest structure for forty years. Eiffel used his experience in building railway bridges when designing the tower, prefabricating the 18,038 wrought iron pieces off site then assembling the pieces with the help of 300 workers.

	The strange attractor; this was proven by W. Tucker in 2001. The strange attractor in this case is a fractal of Hausdorff dimension between 2 and 3. Grassberger (1983) has estimated the Hausdorff dimension to be 2.06 ± 0.01 and the correlation dimension to be 2.05 ± 0.01. Photo credit: Wikimol Archive - Nominate new image

The visible light, looking back in time more than 13 billion years. The HUDF contains an estimated 10,000 galaxies. The patch of sky in which the galaxies reside (just one-tenth the diameter of the full moon ) was chosen because of the low density of bright stars. Although most of the targets visible in the Hubble image can also be seen at infrared wavelengths by ground-based telescopes, Hubble is the only instrument which can make observations of these distant targets at visible wavelengths.

A tapped winding and, in most cases, a magnetic core to concentrate the flux. An alternating current in one winding creates a time-varying magnetic flux in the core, which induces a voltage in the other windings. Transformers are used to convert between high and low voltages, to change impedance, and to provide electrical isolation between circuits . Photo credit: BillC Archive - Nominate new image

Tempel 1. At 5:52 UTC on July 4, 2005, one section of the Deep Impact probe successfully impacted the comet's nucleus , excavating debris from the interior of the nucleus. Photographs of the impact showed the comet to be more dusty and less icy than expected. The impact generated a large, bright dust cloud that obscured the hoped-for view of the impact crater.
