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.

Composite image of the Boomerang Nebula: ALMA observations (orange) showing the hourglass-shaped outflow, which is embedded inside a roughly round ultra-cold outflow; the hourglass outflow stretches more than 1.9 trillion miles from end to end, and is the result of a jet that is being fired by the central star, sweeping up the inner regions of the ultra-cold outflow like a snow-plow; the ultra-cold outflow is about 10 times bigger. The ALMA data are shown on top of an image from the NASA/ESA Hubble Space Telescope (blue). Image credit: ALMA / ESO / NAOJ / NRAO / NASA / ESA / Hubble / AUI / NSF.
