This is the first time a star of extragalactic origin has been found in the vicinity of the super massive black hole.

The four researchers stressed in their paper that they haven't conclusively shown that the black hole's spin "truly powers the extragalactic jet," though the evidence certainly leans in that direction.

Unlike the Hubble and James Webb Space Telescopes, which focus deeply on one part of the sky at a time, scientists will use Euclid to cover wide swaths of the extragalactic sky at once.

An extragalactic outburst whose light hurtled through the inner solar system last fall was 70 times brighter than any other such eruption that scientists have observed, researchers report.

However, in recent research published in Science, an extragalactic source for these subatomic particles has been identified.
