Rivers of Red Ice on Europa
The folks at JPL just published a new image of the surface of Europa – Jupiter’s watery, chaotic, eruptive, and potentially life-harboring satellite. The photograph illustrates the contrast between the moon’s relatively pure water ice (blue-white terrain) and its saltier, and thereby ruddier, surface ice.
According to JPL, the image area measures approximately 101 by 103 miles (163 km by 167 km), and is composited from photographs captured by NASA’s Galileo spacecraft in the late nineties.
Double Red Rainbow at Sunset
Captured at sunset on April 27th, 2014 by Manolis Thravalos from Samos Island, Greece, the sun was behind the camera. The list of optical phenomena is substantial: rainbows, red-tinted sunsets, and brightened sky within the bow.
Rainbows are formed when light catches raindrops just right for a million tiny prisms, splitting the white light into an arc of colour. The raindrops don’t just split the light into rainbows; a portion is also directly reflected. This creates a brightened area below the primary bow. Rayleigh scattering through thicker atmosphere around the horizon means we only see the longest wavelengths, tinting the entire rainbow into sunset reds.

Spirit & Opportunity: 10 Years Roving Across Mars
This exhibition celebrates the amazing images and achievements of the two Mars Exploration Rovers on the 10th anniversary of their landings on the Red Planet.
The twin Mars Exploration Rovers Spirit and Opportunity were launched toward Mars in the summer of 2003. Spirit arrived on January 3, 2004, and Opportunity on January 24, 2004.
Spirit traveled 7.7 kilometers (4.8 miles) over more than six years. Opportunity has traveled more than 38 kilometers (23.6 miles) over an ongoing mission that has reached 10 years.
