Scientists just discovered the possibility of life in Venus' clouds

Scientists just discovered the possibility of life in Venus' clouds

A study published on Monday in the journal Nature Astronomy found that Venus' clouds contain phosphine which may be evidence of alien life.

Phosphone is an extremely flammable, corrosive gas also found on Earth that's produced by anaerobic bacteria and humans in labs.

The study's authors haven't verified the origins of the gas but the sources they've investigated haven't been able to explain the amount of gas they discovered.

"We really went through all possible pathways that could produce phosphine on a rocky planet," Janusz Petkowski, an author of the new study, told MIT News. "If this is not life, then our understanding of rocky planets is severely lacking."



Should the study reveal life it would be one of the most important discoveries in human history. It would also validate a hypothesis posited decades ago by astrophysicist and the original host of TV's, "Cosmos," Carl Sagan.

In the '60s he authored two scientific papers outlining the possibility of life on Venus. He wrote that the planet's surface was too hot to support life but, "while the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether."

In 1967, Sagan and Harold Morowitz, a molecular biophysicist at Yale, posited that there could be a livable layer in Venus' clouds.

Here's Sagan describing the possibility of life in Venus' cloud layer back in 1963.

"Measurements with radio telescopes show, that there is a region on Venus where temperatures are greater than 600 degrees Fahrenheit," Sagan says. "It is just possible, that the hot region exists at a high altitude, in the ionosphere of Venus."

"The surface temperature could then be, almost Earth-like and life as we know it could exist there," Sagan continues. "However, it is more likely that if there is life on Venus it is probably the type we cannot now imagine."

Upworthy readers may be familiar with another prediction Sagan made right before his death in 1996. On "Charlie Rose" he said that due to a lack of scientific skepticism America runs the risk of being taken over by a "charlatan" political leader

It's hard to truly describe the amazing bond between dads and their daughters.

Being a dad is an amazing job no matter the gender of the tiny humans we're raising. But there's something unique about the bond between fathers and daughters.

Most dads know what it's like to struggle with braiding hair, but we also know that bonding time provides immense value to our daughters. In fact, studies have shown that women with actively involved fathers are more confident and more successful in school and business.

Brendan Fraser dressed as Rick O'Connell.

Brendan Fraser might be making the greatest career comeback ever, racking up accolades and award nominations for his dramatic, transformative role in “The Whale." But the OG Fraser fans (the ones who watch “Doom Patrol” solely to hear his voice and proudly pronounce his last name as Fray-zure, for this is the proper pronunciation) have known of his remarkable talent since the 90s, when he embodied the ultimate charming, dashing—and slightly goofball—Hollywood action lead.

Let us not forget his arguably most well known and beloved 90s character—Rick O’Connell from the “Mummy” franchise. Between his quippy one-liners, Indiana Jones-like adventuring skills and fabulous hair, what’s not to like?

During a double feature of “The Mummy” and “The Mummy Returns” in London, moviegoers got the ultimate surprise when who should walk in but Brendan Fraser himself, completely decked out in Rick O’Connell attire. The brown leather jacket. The scarf. Everything.

Gordon Ramsay is not exactly known for being nice.

Or patient.

Or nurturing.

On his competition show "Hell's Kitchen," he belittles cooks who can't keep up. If people come to him with their problems, he berates them. If someone is struggling to get something right in the kitchen, he curses them out.

From 1940 to 1945, an estimated 1.3 million people were deported to Auschwitz, the largest complex of Nazi concentration camps. More than four out of five of those people—at least 1.1 million people—were murdered there.

On January 27, 1945, Soviet forces liberated the final prisoners from these camps—7,000 people, most of whom were sick or dying. Those of us with a decent public education are familiar with at least a few names of Nazi extermination facilities—Auschwitz, Dachau, Bergen-Belsen—but these are merely a few of the thousands (yes, thousands) of concentration camps, sub camps, and ghettos spread across Europe where Jews and other targets of Hitler's regime were persecuted, tortured, and killed by the millions.

What I realized about feminism after my male friend was disgusted by tampons at a party.

"After all these years, my friend has probably forgotten, but I never have."

It’s okay men. You don’t have to be afraid.

Years ago, a friend went to a party, and something bothered him enough to rant to me about it later.

And it bothered me that he was so incensed about it, but I couldn't put my finger on why. It seemed so petty for him to be upset, and even more so for me to be annoyed with him.

Recently, something reminded me of that scenario, and it made more sense. I'll explain.
