About this Image

X-ray image of star cluster Berkeley 87 obtained by XMM-Newton. The sources of soft X-rays are shown in red, the sources of harder X-rays are shown in green, while the hardest sources in the XMM-Newton band are shown in blue. The image is centered on a star of very rare type called Wolf-Rayet. The star WR 142 is seen in the image center as a quite faint blue point. WR 142 is very close to finishing its life in a supernova explosion. XMM-Newton is the first telescope to detect X-ray emission from stars of this type. The extended X-ray emission in the upper part of the image traces region where new massive stars are forming.

Investigator(s):  L.M. Oskinova
