A nebula that extends its hand into space
The Gum Nebula is an emission nebula almost 1400 light-years away. It's home to an object known as "God's Hand" among the faithful. The rest of us call it CG 4.

ENERGY STAR is an international standard for energy efficient consumer products. It was first created as a United States government program in 1992, but Australia, Canada, Japan, New Zealand, Taiwan and the European Union have also adopted the program. Devices carrying the Energy Star logo, such as computer products and peripherals, kitchen appliances, buildings and other products, save 20%-30% on average. However, many European-targeted products are labeled using a different standard, TCO Certification, a combined energy usage and ergonomics rating from the Swedish Confederation of Professional Employees (TCO) instead of Energy Star.
