"Mercury's moon." March 31, 2012. It's a small bright spot in the discovery image, taken yesterday by the MESSENGER wide angle camera. The moon is about 70 m (230 ft) in diameter, orbiting Mercury at a mean distance of 14,300 km (8,890 miles). The name Caduceus, after the staff carried by the Roman god Mercury, is proposed to the IAU. (Credit: NASA) APRIL FOOL!

New Lunar Grazing Module (LGM), “a multi-purpose celestial bovine containment system” according to APOD. APOD admits that there aren't any plans to launch cows into space, So maybe that “the cow jumped over the Moon” story was an April Fool. Supposedly, it's an art work named "Mooooonwalk" on display at a popular science museum, but which one?

Chris Hadfield's grand April Fools' Day finale shows him posing with an alien that just stopped by the station to say hi. "I don't know what it is or what it wants, but it keeps repeating 'Sloof Lirpa' over and over. Alert the press."

This family portrait, a composite of the Jovian system, includes the edge of Jupiter (with the Great Red Spot visible) and Jupiter's four largest moons, known as the Galilean satellites. From top to bottom are Io, Europa, Ganymede, and Callisto. The smallest of these four moons, Europa is about the size of Earth's moon. (photo from NASA)

Sir Patrick Moore (1923 - 2012). British astronomer, broadcaster and writer. Many astronomers - professional and amateur alike - credit Moore with getting them interested in astronomy. His 1987 April Fool about the Jovian-Plutonian Gravitational Effect was a classic, and mocked a popular disaster book of the time.

Multiple frame picture of a meteoroid falling? Taken from the helmet camera of a Norwegian skydiver who was narrowly missed by the rock. Coming so close to April 1st, it sounds like a slightly belated April Fool. Experts examined video footage and said it was consistent with a meteoroid. But later it looked more likely that it was a piece of gravel in the parachute.

This image from Nasa's Spitzer Space Telescope shows a stellar nursery containing thousands of young stars and developing protostars near the sword of the constellation Orion. Massive stars light up the Orion nebula, the bright region near the centre of the image. To the north of the nebula is a dark filamentary cloud of cold dust and gas over five light years long, containing ruby red protostars that jewel the hilt of Orion's sword Photograph: Spitzer Space Telescope/Nasa

Saturn's Iapetus: Painted Moon- Vast sections of this strange world are dark as coal, while others are as bright as ice. The composition of the dark material is unknown, but infrared spectra indicate that it possibly contains some dark form of carbon. A leading hypothesis is that the dark material is mostly dirt leftover when relatively warm but dirty ice sublimates.

HD 106906b: Unique Super-Jupiter Exoplanet Discovered Dec 6, 2013 by Sci-News.com The planet, named HD 106906b, weighs in at 11 times Jupiter’s mass. It orbits a white main-sequence star, HD 106906A, located in the constellation Crux around 300 light-years away from Earth. An international team of astronomers announced the discovery of a giant extrasolar planet orbiting its star at more than 20 times the average Neptune-Sun distance.



This is a fragment from the ‘Murchison Meteorite’ which landed in Victoria, Australia in 1969. It has been dated at nearly 4.95 billion years old – nearly 500 million years older than the age of the Earth.
