The skull of a 66-million-year old Triceratops is expected to raise almost $2 million at auction. Known as Lung Wong, or the Dragon King, the fossilised item is said to be the world's largest intact dinosaur skull, measuring 9.2ft (2.8 metres) long. The auction is open now and the fossil is being sold by Hong Kong-based experts at Evolved. The Dragon King dinosaur skull (pictured) is being sold by Hong Kong-based experts Evolve.

It was no accident that Nasa crashed one of its Apollo 16 rocket boosters onto the moon, but the researchers never intended to lose it. In April of 1972, the booster drifted off and was never seen again, unable to transmit tracking data and reveal its whereabouts because of a malfunction. Now, almost 44 years later, the crash site of the Saturn V stage-three booster has finally been located. The site was identified by Jeff Plescia, a scientist from Johns Hopkins University, and expert in finding objects that have been lost in space. Plescia used high-resolution images produced by the Lunar Reconnaissance Orbiter Camera (LROC) system, according to Science Alert.Stage 3 Saturn V rocket booster disappeared in 1972 Apollo 16 missionThe booster was set to crash onto the moon, and take measurementsMalfunction caused it to become lost, unable to transmit tracking dataJeff Plescia located crash site using the Lunar Reconnaissance Orbiter
