Pale Blue Dot, Voyager 1 image Featured 7 Nov 2013 Print

Pale Blue Dot, Voyager 1 image

This unique narrow-angle color image is of the Earth, dubbed 'Pale Blue Dot', is a part of the first ever 'portrait' of the solar system taken by Voyager 1. The spacecraft acquired a total of 60 frames for a mosaic of the solar system from a distance of more than 4 billion miles from Earth and about 32 degrees above the ecliptic. From Voyager's great distance Earth is a mere point of light, less than the size of a picture element even in the narrow-angle camera. Earth was a crescent only 0.12 pixel in size. Coincidentally, Earth lies right in the center of one of the scattered light rays resulting from taking the image so close to the sun. This blown-up image of the Earth was taken through three color filters -- violet, blue and green -- and recombined to produce the color image. The background features in the image are artifacts resulting from the magnification


Eustachian tube anatomy, artwork Featured 7 Nov 2013 Print

Eustachian tube anatomy, artwork

Eustachian tube anatomy. Artwork of the anatomy of the human Eustachian tube in its normal closed state (main artwork) and in an open state (inset, upper right). The Eustachian tubes (one for each ear) run from the middle ear to the throat. They are also called the auditory tube or pharyngotympanic tube. They allow drainage of fluids such as mucus, and pressure equalising. Methods of equalising pressure (called 'clearing the ears', white arrows) include yawning and swallowing. If pressure is not equalised, the result can be a burst ear drum. The ear drum is at centre in the main artwork, with the inner ear (ear bones, semi-circular canals, and cochlea) above and to its right


Fly life cycle, artwork Featured 7 Nov 2013 Print

Fly life cycle, artwork

Fly life cycle. Diagram and artworks showing the stages in the life cycle of a fly. The winged adult stage is at top centre. The female lays eggs (upper right) that are around 1.2 millimetres in length. These contain embryos and hatch into larvae around 3 millimetres long. Three sizes (instars) of larvae are shown here (across bottom). Once the fly larva (maggot) has reached a certain size (7 to 12 millimetres), it forms a pupal stage (upper left, 8 millimetres long). The adult fly (6 to 7 millimetres long) emerges from the pupa. The whole cycle can last between 10 days and two months depending on conditions
