New study has shone a new light on searching for habitable worlds
When astronomers discovered the first planet outside our solar system, it was orbiting a pulsar, one of the most extreme, radiation-blasted environments imaginable. Not exactly the kind of place you'd expect to find a planet, let alone a representative one. The first confirmed exoplanet was an oddity, a product of the fact that pulsar timing is extraordinarily sensitive, not a reflection of what planets are typically like.
If an alien landed and asked you: ‘What is music?’ what would you play for them?

Can you imagine?
BREAKING NEWS!!!! We found extraterrestrial life at last!!!! Oh, nevermind, it comes from Earth...

Irony aside, it'd still be amazing news.

Habitable Exomoons may outnumber habitable exoplanets. Does that mean life may be on more moons than planets?

Supermassive black holes can render exoplanets uninhabitable at great distances
The thinking around exoplanet habitability is mostly concerned with a planet's distance from its star. Too close, and any surface water is boiled away into space. Too far, and surface water is frozen. Both are severe limits on the prospects for life. Habitability depends on an exoplanet being in the Goldilocks Zone, a distance range around a star where liquid water can persist.
How Mars can help us understand 'marginal' exoplanets
Mars holds a special place in the solar system. It represents marginal habitability. This means it transitioned from warm and wet and potentially hospitable, to cold and dry and inhospitable.
