If life exists in Venus's atmosphere, it could have come from Earth
The theory of panspermia holds that life is spread through the cosmos via asteroids, comets, and other objects. When the building blocks of life emerge on one planet, impacts can eject surface material into space, which then ...

The Habitable Worlds Observatory will need astrometry to find life
We're getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we're looking at an Earth analog somewhere else in the galaxy, we have to directly image it ...

High nickel concentrations in Martian bedrock point to potential biosignatures
In 2024, NASA's Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, ...
Impacts from meteors may have helped start life on Earth by creating hydrothermal vents
Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells could take shape, according to research integrated by a recent Rutgers University graduate. Shea Cinquemani, ...
