RCW 38 X-ray, Radio, Infrared
Composite
This multiwavelength composite of the young star cluster RCW 38 shows the Chandra data (0.5-8 keV) in red, the ISAAC infrared data (K band 2.2 micron) in green and the ATCA radio data (1660.0 MHz, 18cm) in blue. The X-ray image was taken in December 2001, the infrared in November of 1998 and the radio in May of 1996.

Chandra Broadband Image of RCW
38
In addition to the point-like emission from stars, Chandra’s image of RCW 38 reveals a diffuse cloud of X-rays produced by trillion-volt electrons moving in a magnetic field. Such particles are typically produced by exploding stars, or in the strong magnetic fields around neutron stars or black holes, none of which is evident in RCW 38. This broadband image from Chandra shows all the X rays (0.5-8 keV) detected from RCW 38 with colors coded by intensity.

Full-Field Images of RCW 38 (High, Low & Medium
Energy)
A mysterious cloud of high-energy electrons enveloping RCW 38 has been discovered by astronomers using Chandra. These extremely high-energy particles could cause dramatic changes in the chemistry of the disks that will eventually form planets around stars in the cluster. The red image of RCW 38 shows only the highest-energy X-rays detected by Chandra. The green image shows the medium-energy X-rays and the blue image shows the low-energy X-rays (0.5-1.5keV) observed by Chandra.
