The Barringer meteor crater in northern Arizona is the best preserved impact crater on Earth, and was formed 49,000 years ago. The largest known piece from this impact is the iron-nickel Holsinger meteorite, weighing 639 kilograms and measuring 0.9m long. It was found some 2.5 km north of the crater in 1911. Before entering the Earth's atmosphere it is estimated that the meteor was originally 1.186 km wide, and before hitting the ground lost approximately half of its mass burning up, the remaining part exploded and evaporated when it impacted in the ground. The meteorite hit the ground at a speed of 12.8 km per second with an impact force of approximately 2.5 megatons ? 150 times more powerful than the Hiroshima atomic bomb. In 1903 Daniel Barringer suggested that the crater had been produced by the impact of a large iron-metallic meteorite, a theory confirmed by G Shoemaker in 1960.

Computer illustration of SPT2349-56 - a group of interacting and merging galaxies that existed in the early Universe, when it was one tenth of its current age. Mergers like this have been observed using the ALMA and APEX telescopes and represent the formation of galaxy clusters, the most massive objects in the modern Universe. Astronomers thought that these events occurred around three billion years after the Big Bang, but these recent observations revealed them happening when the Universe was only half that age.

Illustration of the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander deploying its Seismic Experiment for Interior Structure (SEIS) onto the Martian surface. The lander's robotic arm (IDA) is removing the protective WTS (Wind and Thermal Shield) from SEIS. The InSight lander is designed to studying the interior of Mars. It will investigate the processes that formed and shaped Mars and its findings will improve our understanding of the evolution of the inner solar system's rocky planets. InSight was launched on 5 May 2018 and successfully landed on Mars on 26th November 2018.

Botulinum toxin nerve block mechanism. Cutaway illustration of a nerve axon terminal and the mechanism by which the botulinum toxin (green) causes nerve paralysis. Inside the nerve are vesicles (spheres) of the neurotransmitter acetylcholine, with ion channels (blue) in the membrane. At lower centre, are SNARE proteins (blue strands) that act at the synaptic junction at the terminal end of the axon to promote the successful release of acetylcholine (one vesicle shown merging with membrane). The toxin breaks these SNARE proteins, preventing the release of acetylcholine and resulting in paralysis of muscles and nerves. This can be swiftly fatal, but is also used in small amounts in medicine.
