This is an artist's impression of the SN 1987A remnant. The image is based on real data and reveals the cold, inner regions of the remnant, in red, where tremendous amounts of dust were detected and imaged by ALMA. This inner region is contrasted with the outer shell, lacy white and blue circles, where the blast wave from the supernova is colliding with the envelope of gas ejected from the star prior to its powerful detonation.

A diagram of the airway lining suggests how the pulmonary neuroendocrine cells (red) trigger a response to inhaled chemicals. When a chemical (orange triangle) docks on a receptor (black) they dump secretory chemicals (thin orange arrows), which have an immediate but localized effect on muscles (blue) and nerves (pink), possibly triggering responses such as a cough.

Galactic distribution of massive young stars and compact and ultra-compact H II regions with luminosities greater than 10^4 times that of the Sun. The map shows the positions of the complexes and individual sources as red and blue circles, respectively. The sizes of the markers give an indication of their luminosity, as depicted in the upper-right corner. The position of the Sun is shown by the small circle above the Galactic Centre. The two solid lines enclose the Galactic Center region that was excluded from survey due to problems with source confusion and distance determination. The smaller of the two dot–dashed circles represents the locus of tangent points, while the larger circle shows the radius of the solar circle.
