Researchers find hints of life in Venus atmosphere

September 14th, 2020

Scientists have detected higher-than-expected levels of a chemical in Venus’s atmosphere that may indicate the presence of life. The chemical can be produced by microbes, but can also be created artificially or within gas giant planets like Jupiter.  Life on the surface of Venus is highly unlikely due to its incredibly hostile climate.  In the …

There’s another ocean world in our solar system

August 11th, 2020

Researchers say they’ve found evidence of recent activity on the surface of the dwarf planet Ceres that suggests there’s water beneath the surface. If Ceres has a vast ocean beneath its icy crust, there’s a chance that it could host life in some form. Ceres is located in the asteroid belt between Mars and Jupiter. …

If there’s life on Mars, this is how we’ll finally find it

July 29th, 2020

There is no evidence that life currently exists on Mars, and its surface is not considered habitable due to radiation and temperature extremes. Beneath the surface, however, organisms could still exist. Future missions to investigate this possibility would need to take subsurface samples for analysis. As far as any of us know, there’s not living …

Should we create our own alien life in outer space?

July 16th, 2020

NASA is doing everything it can to avoid bringing Earthly organisms to other worlds, but what if we should be doing the opposite? Seeding other worlds with life could potentially have big benefits for humanity in the distant future. Icy moons like Enceladus may already host alien life. If you’ve never seen the movie Prometheus — the …

We really, really can’t contaminate other planets with Earth microbes

July 11th, 2020

A pair of new NASA directives tweaks Planetary Protection policies to allow for human exploration of the Moon and Mars Preventing contamination of other worlds is vitally important to making new discoveries and not changing the planets or worlds that we visit. Bringing microbes from Earth to Mars or the Moon could have big impacts …

Scientists say alien life may live on Jupiter’s moon Europa

June 25th, 2020

Jupiter’s moon Europa may have the conditions necessary to support life, a new study claims. The interior of the planet is believed to be liquid water, and if that water has a stable source of heat, life could exist or even thrive there. Future missions to explore Europa could reveal whether or not life has …

Study says Milky Way may host six billion Earth-like worlds

June 18th, 2020

Scientists using data from the Kepler Space Telescope estimate that there are roughly 6 billion Earth-like worlds in the Milky Way galaxy. The researchers suggest the odds of a G-type star hosting an Earth-like planet are roughly one-in-five. A study published early this week suggested there are likely at least 36 intelligent alien civilizations in …

Study says there are 36 intelligent alien races in our galaxy

June 15th, 2020

A new study calculates the number of intelligent alien civilizations likely to exist in the Milky Way. The scientists believe there are roughly 36 intelligent civilizations in our galaxy. The average distance to an alien civilization is calculated to be around 17,000 light-years. As far as we know, humans are the only “advanced” civilization in …

Alien life may thrive on dusty planets, researchers say

June 11th, 2020

Researchers suggest exoplanets with dusty atmospheres may have a better shot at supporting life on their surfaces. Planets with dusty atmospheres may have more stable temperatures on their surfaces, which is a big deal when it comes to life. Unfortunately, while dust may help life take root, it may also obscure our view of a …
