SOLAR ORBITER IN MAGNETIC FIELD SIMULATION FACILITY

Worlds orbiting stars other than our sun are “exoplanets,” and they come in many sizes, from gas giants larger than Jupiter to small, rocky planets. This illustration of a "super-Earth" represents the type of planet that the TESS mission aims to find outside our solar system.

Optical image of spiral galaxy NGC 4330, located in the Virgo Cluster. Ionized gas is shown in red. Blue overlay shows the expected ALMA observations of CO gas. Dr. Brown and his colleagues will use the Atacama Compact Array (ACA) to study the influence of galaxy environment on star formation in the Virgo Cluster.

This picture from Voyager 1 shows the volcano Loki on Jupiter’s moon Io. When this picture was taken, the main eruptive activity came from the lower left of the dark linear feature (perhaps a rift) in the center. Below is the “lava lake,” a U-shaped dark area about 200 kilometers across.
