Some researchers theorized that these afterglows eluded detection because they occurred in a less dense region of a galaxy, where ejected material wouldn't have the opportunity to interact with lots of particles and produce a bright enough burst.

Rotating magnetars that hammer surrounding material with their vast magnetic fields, superluminous supernovae explosions, or immensely volatile cosmic events like supermassive black holes ejecting material are among the theories of what causes FRBs.

Most of the energy from the supernova turns into light when it hits this previously ejected material, resulting in a short, but brilliant burst of radiation.

It is possible that the star spewed out a dense shell of gas about a year before the explosion, and when the supernova happened, ejected material hit the shell.

Dust trapped in polar ice cores shows that ejected material spread around the globe, indicating that the eruption injected substantial material into the stratosphere, where it can strongly affect climate.

The fireballs present a puzzle to astronomers, because the ejected material could not have been shot out by the host star, called V Hydrae.

The scientists are hoping to use ash deposits from these volcanoes to develop a sharper picture of the amount and speed of the ejected material.

As the ejected material rammed into the cloud, some energy from its motion could have been converted into light and heat, powering the dying star's extreme and persistent brightness.

The ejected material's initial blue tint shows that at first, it lacked heavy elements called lanthanides.

They think black holes that dwell in the center of galaxies fling out matter so violently that the ejected material pierces its cloudy surroundings, allowing light to escape.

Then it flung off material and slowed to form a rigid spinning body whose mass researchers could calculate from the masses of the original neutron stars minus the ejected material.

Furthermore, the moons would be extremely dry, even in the context of the Red Planet, as any water vapor contained in the ejected materials from which the moons could have formed would have been lost to space.

Many dying stars and stellar corpses are embedded in their ejected material, which shrouds our view in visible light but can be penetrated with Webb's infrared vision.
