A spider stellar engine could move binary stars halfway across a galaxy
Eventually, every stellar civilization will have to migrate to a different star. The habitable zone around all stars changes as they age. If long-lived technological civilizations are even plausible in our universe, migration ...

Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat ...

Mars may have been habitable much more recently than thought
Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for ...

Could life at TRAPPIST-1 survive the star's superflares?
The TRAPPIST-1 system is a science-fiction writer's dream. Seven Earth-sized worlds orbit a red dwarf star just 40 light-years away. Three of those worlds are within the habitable zone of the star. The system spans a distance ...

Here are some potentially habitable world targets for the upcoming LIFE mission
The odds are good that we are not alone in the universe. We have found thousands of exoplanets so far, and there are likely billions of potentially habitable planets in our galaxy alone. But finding evidence of extraterrestrial ...

Discovery of carbon-storing molecules in a distant interstellar cloud may shed light on how our own solar system formed
A team led by researchers at MIT has discovered that a distant interstellar cloud contains an abundance of pyrene, a type of large, carbon-containing molecule known as a polycyclic aromatic hydrocarbon (PAH).

Life can maintain a habitable environment in hostile conditions, research suggests
Everybody knows that for life to thrive on any world, you need water, warmth, and something to eat. It's like a habitability mantra. But, what other factors affect habitability? What if you relaxed the conditions conducive ...

Rocky planets orbiting small stars could have stable atmospheres needed to support life
Since its launch in late 2021, NASA's James Webb Space Telescope has raised the possibility that we could detect signs of life on exoplanets, or planets outside our solar system.

Giant meteorite impact 3.26 billion years ago may have aided early life
Billions of years ago, long before anything resembling life as we know it existed, meteorites frequently pummeled the planet. One such space rock crashed down about 3.26 billion years ago, and even today, it's revealing secrets ...
