The star is simply dying. Stand by for a supernova.
Looking forward to the James Webb looking at this.
Vital Facts
The James Webb Space Telescope (sometimes called JWST) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity. The longer wavelengths enable JWST to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today.
Proposed Launch Date: JWST will be launched in October 2018.
Launch Vehicle: Ariane 5 ECA
Mission Duration 5 - 10 years
Total payload mass: Approx 6200 kg, including observatory, on-orbit consumables and launch vehicle adaptor.
Diameter of primary Mirror: ~6.5 m (21.3 ft)
Clear aperture of primary Mirror: 25 m2
Primary mirror material: beryllium coated with gold
Mass of primary mirror: 705 kg
Mass of a single primary mirror segment: 20.1 kg for a single beryllium mirror, 39.48 kg for one entire primary mirror segment assembly (PMSA).
Focal length: 131.4 meters
Number of primary mirror segments: 18
Optical resolution: ~0.1 arc-seconds
Wavelength coverage: 0.6 - 28.5 microns
Size of sun shield: 21.197 m x 14.162 m (69.5 ft x 46.5 ft)
Orbit: 1.5 million km from Earth orbiting the L2 Point
