HD 149026 b. One of the hottest & blackest planets yet discovered, the temperature on the sunny side is over 2000 degrees Celsius (3700 F), hot enough to melt iron and boil silicon. The opaque upper layers absorb almost all of its star's light, reflecting nothing. This would make the planet blacker than coal, but glowing softly as it radiates heat.

In 2011 the first "circumbinary planet" - a planet orbiting two stars- was discovered. While the planet's officially called Kepler 16b, astronomers are already referring to it as Tatooine, after the home planet of Luke Skywalker in the Star Wars movies, which also had two suns.

Top 5 Habitable Alien Planets…

From the Kepler data we're finding new planets all the time. Many are more earthlike in size and some are in the habitable zones of their stars. This doesn't mean there is any kind of life on them. There are many other factors that could make them uninhabitable. Mona Evans, "Searching for Extrasolar Planets",

BPM 37093 ("Lucy") is a star composed entirely of diamond. It's 4,000 km across and 10 billion trillion trillion carats. 50 light years from Earth in the constellation Centaurus, it's classified as a crystallized white dwarf, the hot core that remains after a star burns out.

Exoplanets. It *is* an exciting time. This drawing was done in June 2012. By October 2013 there were over 1000 known exoplanets. (Credit: XKCD) Mona Evans, "Searching for Exoplanets"

Kepler-78b has a year 8-1/2 hours long. Its star is cooler than the Sun, but it's still so close that its surface temperature is 7400 degrees C. At that temperature its surface would be boiling lava. In size it may be up to eight times the size of Earth. (Artwork by ESO/L. Calçada) Mona Evans, "Exotic Exoplanets Tour"

An artist's impression of schoolboy Tom Wagg's planet, WASP-142b, orbiting its star, WASP-142. The planet is depicted as seen from a hypothetical moon. A second, dimmer star is seen in the background. Being 1000 light-years away, the planet is too distant to obtain a direct image. (Picture credit: David A.

Astronomers Image Lowest-mass Exoplanet Around a Sun-like Star

Exoplanet GJ 504b (artist's depiction). In the constellation Virgo, the planet glows a dark magenta. It's about four times the mass of Jupiter and when discovered in August 2013, was the lowest-mass planet ever directly imaged around a star like the sun.

Top 10 Bizarre Moons In Our Solar System

Ganymede. It's bigger than Mercury, has a liquid iron core and is the only moon in the Solar System with its own magnetic field. The terrain is varied, but there are broadly two different types: heavily-cratered dark regions (evidence of great age) and brighter regions showing patterns of ridges and grooves for thousands of miles, suggesting later geological activity, but nonetheless ancient. ©Mona Evans,"Jupiter's Galilean Moons"
