Explanation: <\/b><\/p>\n

Could the Little Mermaid<\/a> turn into stardust instead of seafoam?<\/p>\n

It would seem so in this beautiful nebula<\/a>.<\/p>\n

The featured image<\/a> shows the Mermaid Nebula<\/a>, also known as the Betta Fish Nebula, which is part of the G296.5+10.0 Supernova Remnant<\/a>.<\/p>\n

The blue color visible here originates from doubly ionized oxygen (OIII)<\/a>, while the deep red is emitted by hydrogen gas<\/a>.<\/p>\n

\t\t\t\t\t\t\t\t\t\t\t\t Estimated<\/a> to be located a few thousand light-years away and about 10,000 years old, this nebula was formed when a massive star exploded as a supernova<\/a>.
\n\t\t\t\t\t\t\t\t\t\t\t\t It left behind a peculiar<\/a> pulsar<\/a>, a young radio-quiet neutron star that spins around about twice every second<\/a>.<\/p>\n

The bright stars shown in the image are unassociated with the nebula.
\n The pulsar can be detected in the X-rays<\/a> but it does not<\/a> have a confirmed detection in the optical (visible light<\/a>) so far.<\/p>\n

As a result, the pulsar itself is not visible in this image.<\/p>\n
