24 Other Heavenly Bodies That Can Host Life Better

KEY POINTS

  • Study says there are 24 other planets that are better suited for hosting life than Earth
  • Superhabitable planets are considered superior to Earth in terms of age, size, mass, water and humidity
  • The conclusion is based on assessments of 4,500 known exoplanets

Earth may not be the best planet in the universe when it comes to hosting life. According to a study, there are 24 other planets located more than 100 light years away that could host life better than what humans call home.

Some of these candidates orbit stars that are also better suited for sustaining life than Earth’s sun. Most interestingly, there is one that possesses nearly all the strong characteristics of what a superhabitable planet should be. 

In a study published in the journal Astrobiology, a team of scientists observed more than 4,500 exoplanets in the solar system and identified the criteria of superhabitable planets.

Even More Evidence Points to ‘Water Bodies’ Under the Surface of Mars

In 2018, planetary scientist Roberto Orosei and his colleagues stirred up a multi-planetary controversy when they claimed they’d found evidence of a subglacial lake nearly a mile below ice at Mars’s south pole. At the time, fellow planetary scientists met the claims with intense scrutiny.

Now, Orosei, a planetary scientist at Italy’s National Institute for Astrophysics, and his fellow researchers say they have new, additional evidence that these deep, vast subglacial lakes really do exist. They published their findings this week in the journal Nature Astronomy.

🌌 You like badass space stuff. So do we. Let’s nerd out over the universe together.

If these lakes are, in fact, real, they could reshape our understanding of whether life could still exist on Mars. “This area is the closest thing to ‘habitable’ on Mars that has been found so far,” Orosei told Science News.

Study: Mars has four bodies of water underneath surface

Sept. 29 (UPI) — Planetary scientists say in a new report that Mars has four subsurface lakes, which could be a habitat for life.

After finding one location where water may be buried in 2018, researchers did a more detailed analysis of the region using radar data from the spacecraft Mars Express. The new study used data sets from 134 observations from 2012 to 2019, said the report published Monday in Nature Astronomy.

“We identified the same body of water, but we also found three other bodies of water around the main one,” planetary scientist Elena Pettinelli of the University of Rome, a lead co-author of the report, said in a statement. “It’s a complex system.”

The spacecraft used a radar system called the Mars Advanced Radar for Subsurface and Ionosphere Sounding to examine the planet’s southern polar region. The radar bounces radio waves off layers of material on the
