Was the First Planet Beyond the Milky Way Discovered, or Something Even More Exotic? (Weekend Feature)

 

Whirlpool Galaxy

 

In 2019 the Nobel Prize in Physics was awarded to Michel Mayor and Didier Queloz for pioneering a new field in astronomy with the discovery of the first planet beyond our solar system, 51 Pegasi b. Since the discovery in 1991, over 4,000 exoplanets have been found in our home galaxy. “We answered a very old question,” Mayor said, which was debated by philosophers since the ancient Greeks: “are there other worlds in the Universe?”

So far, we have had only close calls from gamma ray explosions so large, scientists have suggested, that if they occurred within our solar neighborhood (less than 1,000 light years) they could potentially trigger mass extinctions on Earth.

Will Galaxies and Intelligences They Host Beyond the Observable Universe Evolve Like Our Own?

 

Alien Galaxy

 

“The volume of space-time within range of our telescopes—what astronomers have traditionally called ‘the universe’—is only a tiny fraction of the aftermath of the big bang,” says astrophysicist Martin Rees. “We’d expect far more galaxies located beyond the horizon, unobservable, each of which –along with any intelligences it hosts– will evolve rather like our own.”

“A Very Strange World” –Neptune’s Mystery Moon Triton

Triton Moon of Neptune

 

When NASA’s Voyager 2 spacecraft flew by the strange world of Neptune’s largest moon, Triton, three decades ago, it imaged a world as stunning as it was puzzling, revealing massive, dark plumes of icy material spraying out from its surface, a captured Kuiper Belt object that evolved, a potential ocean world with active plumes, an energetic ionosphere and a young, unique surface. Voyager 2 is the only spacecraft ever to have flown past Neptune, leaving a trail of intriguing, unanswered questions that NASA hopes to answer.
