Image of Jupiter taken on May 18, 2017, one day before the Juno spacecraft’s sixth close approach to Jupiter, taken with a filter centered at 8.8 microns that is sensitive to Jupiter’s tropospheric temperatures and the thickness of a cloud near the condensation level of ammonia gas. The Great Red Spot appears distinctively at the lower center of the planet as a cold region with a thick cloud layer. It is surrounded by a warm and relatively clear periphery. To its northwest is a turbulent and chaotic region of gas with bands of alternative warm, dry and cold, moist gas. Many other features are also present...

2XMM J14345J0.5+033843 lies nearly 400 million light-years away from Earth. It is a Seyfert galaxy that is dominated by something known as an Active Galactic Nucleus — its core is thought to contain a supermassive black hole that is emitting huge amounts of radiation, pouring energetic X-rays out into the universe. The other fuzzy object in the frame was named in the same way — it is a bright galaxy named 2XMM J143448.3+033749.

Image: First, a flexible stamp is inked with the APTES solution (i). The stamp is then pressed onto the glass surface (ii). A microfluidic channel is placed over the APTES pattern on the glass (iii), and the device is ready to be used to immobilize bioreceptors and, eventually, to help make a diagnosis (iv).
