The Possibility of Interstellar Travel

Artist concept for a futuristic starship.

Mankind depends on exploration. We long to satisfy our curiosity for what lies in every direction, expanding trade routes and learning to adapt to new terrain. And while it used to suffice us to explore our Earth, we’re now directing our gaze somewhere much, much further from home. Star systems

Scientist develops database for stellar-exoplanet ‘exploration’

stellar exoplanet

A Southwest Research Institute scientist is using big data to help the scientific community characterize exoplanets, particularly alien worlds orbiting nearby stars. Of particular interest are exoplanets that could harbor life."At first scientists focused on temperatures, looking for exoplanets in the 'Goldilocks zone'—neither too close, nor too far from the

The Universe Is Really Greasy, And We Had No Idea

The Universe Is Really Greasy

If we're going to head out into interstellar space one day, we might want to go equipped with some heavy-duty degreaser. New research has found that the vast intervals of space aren't always filled with dry dust, but often contain a mist of greasy molecules.And there's a lot of space

Water May Not Be the Only Sign of Alien Life

Alien Water Live

(Inside Science) – When it comes to looking for alien life, scientists mostly focus on where there is water. Now researchers suggest that looking at "bioessential" elements such as phosphorus and molybdenum could help judge a world's potential for life.There is life virtually wherever there is water on Earth, from

Exoplanets could easily survive in double- and triple-star systems

Exoplanets

Over 3,700 exoplanets have been found lurking around our universe, and although each has its own unique set of characteristics, the vast majority have one thing in common: they orbit a single star. Researchers once believed that it would be near impossible for planets to survive outside of single-star systems,

Looking For Hazards In The Alpha Centauri Star System

Alpha Centauri

In humanity's search for life outside our Solar System, one of the best places scientists have considered is Alpha Centauri, a system containing the three nearest stars beyond our Sun.A new study that has involved monitoring of Alpha Centauri for more than a decade by NASA's Chandra X-ray Observatory provides
