Advanced MRI brain scan
Advanced MRI brain scan. This 3D magnetic resonance imaging (MRI) scan of a normal human brain has been produced by the 3T MRI scanner at Neurospin, one of the most advanced MRI research centres in the world. The front of the brain is at left. The coloured lines indicate the many neural pathways that exist in the brain. Neurospin has 3T and 7T scanners. The 'T' designations refer to the magnetic field strengths of 3 Tesla and 7 Tesla. These are extremely strong magnetic fields, and hence this technique is known as ultra high-field magnetic resonance imaging. The high magnetic field strength allows detailed examination of the brain and brain disorders. Neurospin was founded in 2006, and is located near Paris, France.

Lungs, 3D MRI scan
Lungs. Coloured 3D magnetic resonance imaging (MRI) scan of healthy lungs, showing the bronchial tree (brown). The bronchial tree consists of bronchioles (lung airways) that branch out from one of two bronchi (at centre, not seen). Air from the mouth passes through the trachea (windpipe) and the bronchi to reach the bronchioles, where it fills tiny sacs (alveoli). In the alveoli, oxygen from the air is exchanged with carbon dioxide from the blood. Some chest bones can also be seen (white), such as the clavicle (collarbone, across top), spine (running down centre) and ribs (surrounding the lungs).

Art Deco Poster Advertising Amalthea
Amalthea is a moon of Jupiter, the third closest to the planet at 181365 km away (about 2.6 Jupiter radii from the centre of the planet). At just 250 km across at its widest point its shape is not spherical - Amalthea is small, likely a captured asteroid. This image portrays a potential exploration party on the surface of Amalthea. From there, the globe of Jupiter spans an incredible 46 degrees of arc across the sky. The scene is presented as a faux travel poster in art deco style.
