Signs of Water Found on 5 Alien Planets by Hubble Telescope
NASA’s Hubble Space Telescope has detected water in the atmospheres of five planets beyond our solar system, two recent studies reveal.
The five exoplanets with hints of water are all scorching-hot, Jupiter-size worlds that are unlikely to host life as we know it. But finding water in their atmospheres still marks a step forward in the search for distant planets that may be capable of supporting alien life, researchers said.
Measurements: overall length: 68.8 cm, blade length: 15 cm, hilt length: 89 cm. Width: 9.3 cm. Depth: 6.7 cm
Inscriptions: inscribed ‘Francisco (Ru)iz en Toleto’
This is an early example of a small sword. The hilt bears the mark of a goldsmith and is elaborately decorated with enamel and gold wire. Later blades were often mass-produced but this one has been cut down from a prized Toledo rapier blade of around 1620.
From around 1640, light swords with short, flexible, pointed blades appeared in response to new fencing techniques that emphasised thrusting at speed. They were worn increasingly with civilian clothes as ‘small swords’, offering a means of self-defence but largely denoting status for the well-dressed gentleman.
Small swords were items of male jewellery. By the 1750s, their elaborate gold and silver hilts, mounted with precious stones and fine enamelling, were the products of the goldsmith and jeweller rather than the swordsmith. They made fitting rewards for distinguished military and naval service. With their blades tucked away inside scabbards, it was their ostentatious and expensive hilts that carried their thrust.
