It's a bird, it's a plane, it's ... a manatee? The National Radio Astronomy Observatory (NRAO) believes that a gas cloud in the constellation Aquila bears an uncanny resemblance to the endangered aquatic mammal.
Heidi Winter, executive assistant to NRAO's director, first noticed the similarity. And Tania Burchell, an NRAO media producer who used to work in manatee conservation, quickly saw it as "a wonderful opportunity to bridge two worlds—biology and astronomy."
The cloud, or nebula, which is named W50, has more in common with manatees than just its shape. It is the remnant of a star explosion from 20,000 years ago. Particle beams that shoot from the explosion's center, where a star and a black hole orbit each other, form a spiral pattern resembling scars.
