Webb locates dust reservoirs in two supernovae

Supernovae, the explosive deaths of stars, are some of the universe's biggest bursts of energy and light. When they erupt, one supernova can shine even brighter than an entire galaxy.

The Helix nebula: Bigger in death than life

(Phys.org)—A dying star is refusing to go quietly into the night, as seen in this combined infrared and ultraviolet view from NASA's Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent ...

Giant star expels multiple dust shells

An international team led by Leen Decin, a K.U. Leuven (Belgium) astronomer, has discovered a series of dust shells in the vicinity of CW Leonis, a dying giant star. The star expelled the shells in the course of its long ...

A ghostly green bubble: VLT snaps a planetary nebula

(Phys.org) —This intriguing new picture from ESO's Very Large Telescope shows the glowing green planetary nebula IC 1295 surrounding a dim and dying star located about 3300 light-years away in the constellation of Scutum ...

Dying stars could seed interstellar medium with carbon nanotubes

Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation ...

A ghostly trio from Spitzer Space Telescope

(Phys.org) —In the spirit of Halloween, scientists are releasing a trio of stellar ghosts caught in infrared light by NASA's Spitzer Space Telescope. All three spooky structures, called planetary nebulas, are in fact material ...
