A dead star may have munched down on an icy exomoon
We have yet to confirm the existence of moons beyond the solar system, but astronomers say they may have found exomoon remains in the atmosphere of a dead star Source: https://www.newscientist.com/article/2266957-a-dead-star-may-have-munched-down-on-an-icy-exomoon/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Stars and skulls: New ESO image reveals eerie nebula
This ethereal remnant of a long dead star, nestled in the belly of The Whale, bears an uneasy resemblance to a skull floating through space. Captured in astounding detail by ESO’s Very Large Telescope (VLT), the eerie Skull Nebula is showcased in this new image in beautiful bloodshot colors. This planetary nebula is the first known to be associated with a…
The first star in our galaxy caught sending out fast radio bursts is doing it again

Giant ‘survivor’ planet found orbiting dead star
For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

What are white dwarf stars?
White dwarfs are dead stars. A single white dwarf contains roughly the mass of our sun in a volume no bigger than our planet. Our sun will become a white dwarf someday. Source: https://earthsky.org/astronomy-essentials/white-dwarfs-are-the-cores-of-dead-stars…
Dead star emits never-before seen mix of radiation
A global collaboration of telescopes including ESA’s Integral high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy—something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery.

Array of radio telescopes reveals explosion on the surface of a hot dead star
An international group of researchers observed a source of variable gamma rays identified in 2010 by the NASA satellite Fermi. They used a technique called VLBI, that combines data from several radio telescopes on Earth, to produce the sharpest images to date. Surprisingly, the source of gamma rays was a symbiotic nova, a peculiar stellar system known to astronomers as V407…
