Fierce Winds Quench Wildfire-like Starbirth in Far-flung Galaxy
CK Vulpeculae star-on-star collision takes the form of dual rings of dust and gas resembling an hourglass with a compact central object.
A brown dwarf (a so-called failed star without the mass to sustain nuclear fusion) merged with a white dwarf (the elderly, cooling remains of a Sun-like star).
According to the researchers, the white dwarf would have been about 10 times more massive than the brown dwarf, though much smaller in size.
As the brown dwarf spiraled inward, intense tidal forces exerted by the white dwarf would have ripped it apart.

Milky Way's galactic center seen from the X-ray (blue) through the infrared (red).
X-ray glow (shown here in purple) emitted by the hot gas that pervades the galaxy cluster XLSSC006.
The cluster is home to a few hundreds of galaxies, large amounts of diffuse, X-ray bright gas, and even larger amounts of dark matter, with a total mass equivalent to some 500 trillion solar masses. Because of its distance from us, we are seeing this galaxy cluster as it was when the Universe was only ~9 billion years old.
The galaxies that belong to the cluster are concentrated towards the center, with two dominant members. Since galaxy clusters normally have only one major galaxy at their core, this suggests that
XLSSC006 is undergoing a merger event.
