In this color composite image of the RCW 120 nebula (above), an expanding bubble of ionized gas, about ten light-years across, is revealed. It is causing the surrounding material to collapse into dense clumps where star formation occurs.

These images showcase the fine-scale structure of the atmosphere of Uranus, and contain vastly more detail than other images. The images were taken by the adaptive-optics-equipped telescope, the Keck II, which employed its NIRC2 camera.

The Necklace Nebula (PN G054.2-03.4) is a planetary nebula situated in the northern constellation Sagitta, and is located about 15,000 light-years away. It was first discovered by the Isaac Newton Telescope Photometric H-alpha Survey (IPHAS) in 2005. The mission is ground-based and focused on the North Galactic Plane.

The White Sea Biological Station sits at latitude 66° N, just on the cusp of the Arctic Circle, and on the shores of the White Sea, a lone arctic biologist explores the depths of the waters, photographing stunning pictures of arctic life. The only way to get there is by boat in summer and by snowmobile in winter.

A step beyond transparent display, soap bubble displays are actually something possible. Ultrasonic vibrations shot through the soap bubble display alter the images’ texture. More than just a two-dimensional display, these kinds of displays could even create a 3D image if stacked properly.

Rediscovered aerial photos of Greenland from the 1930s have allowed scientists to construct the history of the glacier retreat and advance in the area. The photos were rediscovered in a castle outside Copenhagen, Denmark, and they have allowed Anders Bjork and his colleagues to develop a deeper understanding of how climate change has affected the ice loss and glacier movements of the last 80 years.

NASA’s HiRISE spacecraft, which is currently orbiting Mars, spotted these interesting patterns, which are actually rare lava flows. This is the first time that lava flows have been seen on Mars, and the corkscrew snail shell-like patterns are indicative of previous volcanic activity.

The Helix Nebula in the Aquarius constellation, located some 700 light-years away from Earth, was just observed by the piercing infrared gaze of the VISTA telescope at the Paranal Observatory in Chile. Some have referred to the images as the Eye of Sauron, from JRR Tolkien’s Lord of the Rings.
