What it would mean to find life on Venus

Scientists think they may have found an indicator of life in Venus’ clouds — a discovery that, if confirmed, will cause them to re-examine everything they thought they knew about how life evolves.

The big picture: If life does exist within a small niche of habitability in Venus' temperate layer of clouds, it might mean that life could be even more ubiquitous in the universe than previously expected. The discovery is already fueling calls from scientists who want a mission sent to the nearby world.

  • "If we have Venus also creating life, amidst some completely different scenarios from what we have on Earth, it would be really quite silly to think there's some unique thing about our solar system," Clara Sousa-Silva, an author of the new Venus study and researcher at MIT, told Axios.

Catch up quick: On Monday, scientists announced the discovery of phosphine — a possible sign of life — in the clouds of Venus' upper atmosphere.

  • The gas isn't a sure-fire sign that microbes are floating around in the planet's clouds, but the researchers behind the study haven't yet been able to find another explanation for why the phosphine exists.
  • Future observations will focus on confirming the phosphine detection and scientists are advocating for a Venus probe that might be able to sniff out the gas — and possibly life — in the planet's atmosphere.

The big question: What kind of life could exist within Venus' clouds?

  • Scientists think Venus once was somewhat like Earth, long-lived bodies of water on its surface. But hundreds of millions of years ago, a runaway greenhouse effect took over, leaving the planet shrouded in dense clouds and host to an inhospitable surface.
  • On Venus, microbes or even other creatures living in the clouds could be the last holdouts after a violent reordering of their world's climate — or it could be life that evolved independently in the clouds.
"If there had been life there when it was habitable, maybe that life managed to adapt. Or maybe only the few life forms that could make it into the clouds, they watched a worldwide massacre of every other lifeform they knew, and this is them hanging on to the very end, and we're witnessing this kind of final chapter of life on Venus."

Yes, but: Even if life is confirmed on Venus, it will still take time and a lot of analysis to figure out its origins.

  • Scientists have long wondered if life could have been seeded throughout the solar system either though meteorites or some other mechanism that spreads material around the solar system.
  • If life came to be on Venus entirely independently of life on Earth, however, that would tell researchers something important about how exactly life evolves, potentially providing answers to a number of questions about the nearby planet's history and evolution.
  • "That's why this has the potential to open a lot of doors that we haven't really appreciated before," planetary geologist Paul Byrne, who wasn't involved in the new study, told Axios.

Biden will reverse Trump's attempt to lift travel restrictions from Europe and Brazil

The incoming Biden administration will reverse President Trump's last-minute order to lift COVID-19 related travel restrictions, Jen Psaki, the incoming White House press secretary, tweeted.

Why it matters: President Trump ordered entry bans lifted for travelers from the U.K., Ireland, Brazil and much of Europe to go into effect Jan. 26, but the Biden administration will "strengthen public health measures around international travel in order to further mitigate the spread of COVID-19," Jen Psaki said. Biden will be inaugurated on Wednesday, Jan. 20 and Trump will no longer be president by the time the order is set to go into effect.

Off the rails: Inside Trump’s aborted plan to control the CIA

Beginning on election night 2020 and continuing through his final days in office, Donald Trump unraveled and dragged America with him, to the point that his followers sacked the U.S. Capitol with two weeks left in his term. This Axios series takes you inside the collapse of a president.

Episode 5: President Trump becomes increasingly rash, and devises a plan to tamper with the nation's intelligence command.

In his final weeks in office, after losing the election to Joe Biden, President Donald Trump embarked on a vengeful exit strategy that included a hasty and ill-thought-out plan to jam up CIA Director Gina Haspel by firing her top deputy and replacing him with a protege of Republican Congressman Devin Nunes.

Biden Cabinet confirmation schedule: When to watch hearings

The first hearings for President-elect Joe Biden's Cabinet nominations begin on Tuesday, with testimony from his picks to lead the departments of State, Homeland and Defense.

Why it matters: It's been a slow start for a process that usually takes place days or weeks earlier for incoming presidents. The first slate of nominees will appear on Tuesday before a Republican-controlled Senate, but that will change once the new Democratic senators-elect from Georgia are sworn in.
