This is a composite picture showing images of storms on Neptune from Hubble (left) and Voyager 2 (right). The Hubble image shows a new dark storm (top center). In the Voyager image, a storm known as the Great Dark Spot is seen at the center. It is about 8,000 miles by 4,100 miles (13,000 km by 6,600 km) in size -- as large along its longer dimension as the Earth. The white clouds seen hovering in the vicinity of the storms are higher in altitude than the dark material. Image credit: NASA / ESA / Hubble / GSFC / JPL.

The CTB 1 supernova remnant resembles a ghostly bubble in this image, which combines new 1.5 GHz observations from the Very Large Array (orange, near center) with older observations from the Dominion Radio Astrophysical Observatory’s Canadian Galactic Plane Survey (1.42 GHz, magenta and yellow; 408 GHz, green) along with infrared data (blue). The VLA data clearly reveal the straight, glowing trail from PSR J0002+6216 and the curved rim of the remnant’s shell. Image credit: Jayanne English, University of Manitoba / NRAO / F.

The ‘Teacup’ quasar is causing an ongoing storm. The ‘handle’ is a ring of X-ray (blue) and optical (red and green) light surrounding a giant bubble, shown in the Chandra and Hubble data. This handle-shaped feature, which is located about 30,000 light-years from the galaxy’s central supermassive black hole, was likely formed by one or more eruptions powered by the black hole.

Recent observations show that the object is moving faster than predicted while leaving the Solar System. Astronomers assume that venting material from its surface due to solar heating is responsible for this behavior. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. Image credit: NASA / ESA / Hubble / ESO / M. Kornmesser.
