The time series shows the passage of the "Red Spot Jr." in a band of clouds below (south) of the Great Red Spot (GRS). "Red Spot Jr." first appeared on Jupiter in early 2006 when a previously white storm turned red. This is the second time, since turning red, it has skirted past its big brother apparently unscathed.
But this is not the fate of "baby red spot," which is in the same latitudinal band as the GRS. This new red spot first appeared earlier this year. The baby red spot gets ever closer to the GRS in this picture sequence until it is caught up in the anticyclonic spin of the GRS.
In the final image the baby spot is deformed and pale in color and has been spun to the right (east) of the GRS. (Amateur astronomers' observations confirm that this is the baby spot that migrated around the GRS.) The prediction is that the baby spot will now get pulled back into the GRS "Cuisinart" and disappear for good. This is one possible mechanism that has powered and sustained the GRS for at least 150 years.
These three natural-color Jupiter images were made from data acquired on May 15, June 28, and July 8, 2008 by the Wide Field Planetary Camera 2 (WFPC2). Each one covers 58 degrees of Jovian "latitude" and 70 degrees of "longitude" (centered on 5 degrees South latitude and 110, 121 and 121 degrees West longitude, respectively).

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
