The Mobile Base System moves on the Mobile Transporter rail car along truss rails covering the length of the space station. It provides a movable platform for Canadarm2 and Dextre and can access any of eight worksites that feature power connections.

Number of sources as a function of Galactic longitude in each of the six pass bands, with Sloan i < 20.5 magnitudes.

The 3D rendition above shows two coronae observed on the surface of Venus. The ring-like structures are formed when hot material from deep inside the planet rises through the mantle and erupts through the crust. Research by UMD’s Laurent Montesi found that at least 37 coronae on Venus represent recent geologic activity, including the one named Aramaiti, seen on the left in this image. The black line represents a gap in data.

Researchers at Berkeley Lab and Carnegie Mellon University have designed new solid electrolytes that light the path to wider electrification of transportation.

The Atacama Cosmology Telescope measures the oldest light in the universe, known as the cosmic microwave background. Using those measurements, scientists can calculate the universe’s age.

This illustration shows a black hole surrounded by a disk of gas. In the left panel, a streak of debris falls toward the disk. In the right panel, the debris has dispersed some of the gas, causing the corona (the ball of white light above the black hole) to disappear.

Cases of Black Hole Mistaken Identity

This diagram shows how a shifting feature, called a corona, can create a flare of X-rays around a black hole. The corona (feature represented in purplish colors) gathers inward (left), becoming brighter, before shooting away from the black hole (middle and right). Astronomers don't know why the coronas shift, but they have learned that this process leads to a brightening of X-ray light that can be observed by telescopes.
