...Figure 3. This image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows fine details in a planet-forming disk surrounding a young star, HL Tau. The rings and gaps in the disk are thought to be related to forming planets. ...

...Figure 4 Atacama Large Millimeter/submillimeter Array (ALMA) image of the ring of dust and carbon monoxide emission around the star HD 181327 (false color image), proposed to be arising from a shell of comets. The white contours represent the inner and outer dimensions of the Kuiper Belt in our...

... with astonishing detail through telescopes such as the Hubble Space Telescope or the Atacama Large Millimeter/submillimeter Array ( ALMA ). The iconic ALMA picture of the young stellar object HL Tauri (see title figure) shows the disk around a star <1 My old, at submillimeter wavelengths. The dark...

... of star formation. For example, Hubble Space Telescope images show that stars often form in clusters, the “stellar nurseries” within the Orion nebula being an example. New images from the Atacama Large Millimeter/submillimeter Array (ALMA) telescope ( Fig. 1 ) show dusty disks during the planet-forming...

... easily linked to the Earth-based protoplanetary disk observations made at the international ALMA (Atacama Large Millimeter/submillimeter Array) facility in Chile. The NASA Deep Impact mission to comet 9P/Tempel 1 showed that the water-ice that was driving the comet's activity was close to the surface...

... in the midplane at ca. 20K could be well preserved. A spatially sophisticated disk model simulating water vapor distribution in protoplanetary disks shows rich water directly beneath the photon dominated region of the disk ( Du and Bergin 2014 ). Recent observations by ALMA (Atacama Large Millimeter/submillimeter...
