When a star is born, the leftover dust and gas in the cloud from which it formed doesn’t just sit there. It clumps together, forming other cosmic objects — asteroids and comets and meteors and, yes, exoplanets. We’ve detected many of these exoplanets in orbit around alien stars in the Milky Way.

But not all exoplanets stay put. Some get gravitationally kicked away from their parent star, to wander the galaxy, cold and alone. These are less easy to detect — but, after careful combing through data from NASA’s planet-hunting Kepler space telescope, astronomers think they’ve found some.

In the latest addition to the phosphine on Venus debate, a team of scientists suggests the phosphine is a result of volcanic activity.

If there’s alien life nearby, where are we most likely to find it?

From nearby planets like Venus and Mars, to distant moons like Europa and Titan, these are worlds where we’re most likely to find alien life.

Case in point, a subsidiary of Russia’s Roscosmos space agency is now proposing a nuclear power station on Mars, intended to power a future Russian base on the Red Planet, state-run news agency Sputnik reports.

The Arsenal Design Bureau, the subsidiary, is recommending using the same technologies destined for Zeus, a proposed interplanetary space tug, to power a nuclear reactor on the Martian surface as well.

The massive space tug is designed to make use of a nuclear-powered electric propulsion system to deliver payloads throughout the solar system. Earlier this year, Roscosmos chief Dmitry Rogozin suggested that Zeus could also visit other planets, including Jupiter, to search for alien life. Russia is hoping to begin flight-testing it starting around 2030.

Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research is presented at the Goldschmidt Geochemistry Conference.

Since the first discovery of exoplanets (planets orbiting distant stars) in 1992, scientists have been looking for worlds that might support life. It is believed that to sustain even basic life, exoplanets need to be at just the right distance from their stars to allow liquid water to exist; the so-called “Goldilocks zone.” However, for more advanced life, other factors are also important, particularly atmospheric oxygen.

Oxygen plays a critical role in respiration, the chemical process which drives the metabolisms of most complex living things. Some basic life forms produce oxygen in small quantities, but for more complex life forms, such as plants and animals, oxygen is critical. Early Earth had little oxygen even though basic life forms existed.

Detecting ‘technosignatures’ such as hypothetical Dyson spheres in space could lead us to extraterrestrial life, and now NASA is funding the search.

Among the three billionaires throwing money behind their own rockets in a race to space, Richard Branson may be the first to take flight after his company Virgin Galactic received approval from the U.S. aviation safety regulator to fly people to space.
