The star is actually a binary pair of rare stars in the constellation of Cygnus, and their interactions produce precise periodic eruptions of dust that are expanding out in shells into the space around the pair over time. These shells of dust are glowing in infrared, which has allowed an instrument as sensitive as Webb’s MIRI to resolve them in exquisite detail. See JWST Image Library
One thought on “WR140 Binary observed by JWST”
Hi Dennis, A fantastic image. I’ve been periodically checking out Webb telescope images. An astronomer friend came up with a very nice image. Here is the description:
“The Heart Nebula (also known as the Running dog nebula, IC 1805, Sharpless 2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia.”
I can send it to you if you’d like. I am living in SS MD and interested in Collington.
