New ALMA data reveal a diffuse envelope of carbon monoxide gas (shown in red), which surrounds regions of active star formation (yellow); by dissecting these regions with this powerful radio telescope, astronomers are uncovering clues to the processes and conditions that drive furious star formation; the ALMA data are superimposed on a Hubble image.

This image is a composite of several images taken during two separate Titan flybys in 2006. The large circular feature near the center of Titan's disk may be the remnant of a very old impact basin. The mountain ranges to the southeast of the circular feature, and the long dark, linear feature to the northwest of the old impact scar may have resulted from tectonic activity on Titan caused by the energy released when the impact occurred.

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.

This image of Herbig-Haro object HH 46/47 combines radio observations with ALMA with visible light observations from the New Technology Telescope. The ALMA observations, orange and green, lower right, of the newborn star reveal a large energetic jet moving away from us, which in the visible is hidden by dust and gas. To the left, in pink and purple, the visible part of the jet is seen, streaming partly towards us. Credit: ESO /ALMA / NAOJ / NRAO / H. Arce. Acknowledgements: Bo Reipurth.
