Tour: Chandra Sees Evidence for Possible Planet in Another Galaxy
Tour: Chandra Sees Evidence for Possible Planet in Another Galaxy
Astronomers have found evidence for a possible planet candidate in the M51 ("Whirlpool") galaxy, representing what could be the first planet detected outside of the Milky Way. (2021-10-25)


G327.1-1.1 in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): G327.1-1.1 is the aftermath of a massive star that exploded as a supernova in the Milky Way galaxy. A highly magnetic, rapidly spinning neutron star called a pulsar was left behind after the explosion and is producing a wind of relativistic particles, seen in X-rays by Chandra and XMM-Newton as well as in radio data. This structure is called a pulsar wind nebula. No clear explanation is yet known for the unusual shape of this supernova remnant. One possibility is that we are seeing the effects of a shock wave bouncing backwards off of the shell of material swept up by the blast wave. The X-ray observations allow scientists to estimate the energy released during the supernova explosion and the age of the remnant, as well as the amount of material being swept up as the blast wave from the explosion expands.
