Astronomers found Earth's 'older, bigger cousin.' And it's incredible.

It has a lot in common with Earth.

A long time ago in a galaxy far, far away ... wait, no.

Today, in our galaxy, NASA announced something big.

Astronomers from the Kepler spacecraft mission — a team devoted to spotting other worlds floating around out there in the abyss — announced the discovery of another planet.


That news (while admittedly pretty cool) isn't too groundbreaking on its own. After all, there are lots of other planets out there. But the characteristics of this particular new planet are what really has people talking.

The spacecraft identified Kepler-452b — a planet strikingly similar to Earth in many, many ways.

So similar, in fact, it's the most Earth-like planet we've ever discovered. In other words — from what NASA knows of Kepler-452b now — it could have the potential to host life.

Kepler-452b is in its star's habitable zone, which means liquid water could exist there.

Earth is unique in that it's not too hot or cold for liquid water to exist. This is largely due to our placement within our solar system — we're not too far away or too close to the sun.

We're in our solar system's "Goldilocks zone," if you will.

Kepler-452b is incredibly similar to Earth in this regard. Kepler-452b revolves around its star every 385 days, as opposed to Earth's 365.

Speaking of Kepler-452b's host star ... it's the same type as our sun. That's important.

Stars are just like people — they come in all shapes and sizes (and temperatures). Those factors greatly affect the planets that revolve around them.

While Kepler has discovered other planets similar to Earth in some respects, this is the first time scientists have spotted one that's in the habitable zone of a G star, like our sun.

Kepler-452b and Earth are about the same size, too. And our "older, bigger cousin" might have volcanoes!

Kepler-452b's radius is just about 1.5 times that of Earth's. NASA believes there's a good chance Kepler-452b is also a rocky planet (as opposed to a big ball of gas), like Earth. If it is, Kepler-452b likely has volcanic activity.

Not too different, huh? Just so we're clear, though — Earth and Kepler-452b aren't actually this close. Kepler-452b is about 1,400 light years away from us.

Right now, though, we have more questions than answers when it comes to Kepler-452b.

There's still a lot to learn about our new (relatively close) neighbor.

When reached for comment, NASA's Michele Johnson told Upworthy that NASA still isn't sure if Kepler-452b has an atmosphere. We may only figure that out when we have more technologically advanced space telescopes, according to John Grunsfeld, NASA's associate administrator.

But let's not let Kepler-452b hog the spotlight! It's just one of a dozen other potential Earth-like planets Kepler announced in its latest update.

While Kepler-452b is the only "Earth 2.0"-type planet NASA confirmed on July 23, 2015, the group recently discovered a dozen other possible Earth-like planets.

So for anyone hoping we stumble upon another Earth out there, there's still plenty to look forward to.

On an old episode of "The Oprah Winfrey Show" in July 1992, Oprah put her audience through a social experiment that puts racism in a new light. Despite being nearly two decades old, it's as relevant today as ever.

She split the audience members into two groups based on their eye color. Those with brown eyes were given preferential treatment by getting to cut the line and given refreshments while they waited to be seated. Those with blue eyes were made to put on a green collar and wait in a crowd for two hours.

Staff were instructed to be extra polite to brown-eyed people and to discriminate against blue-eyed people. Her guest for that day's show was diversity expert Jane Elliott, who helped set up the experiment and played along, explaining that brown-eyed people were smarter than blue-eyed people.

Watch the video to see how this experiment plays out.

Cadbury has removed the words from its Dairy Milk chocolate bars in the U.K. to draw attention to a serious issue, senior loneliness.

On September 4, Cadbury released the limited-edition candy bars in supermarkets and for every one sold, the candy giant will donate 30p (37 cents) to Age UK, an organization dedicated to improving the quality of life for the elderly.

Cadbury was prompted to help the organization after it was revealed that 225,000 elderly people in the UK often go an entire week without speaking to another person.

Well Being

Young people today are facing what seems to be greater exposure to complex issues like mental health, bullying, and youth violence. As a result, teachers are required to be well-versed in far more than school curriculum to ensure students are prepared to face the world inside and outside of the classroom. Acting as more than teachers, but also mentors, counselors, and cheerleaders, they must be equipped with practical and relevant resources to help their students navigate some of the more complicated social issues – though access to such tools isn't always guaranteed.

Take Dr. Jackie Sanderlin, for example, who's worked in the education system for over 25 years, and as a teacher for seven. Entering the profession, she didn't anticipate how much influence a student's home life could affect her classroom, including "students who lived in foster homes" and "lacked parental support."

Valerie Anglemyer, a middle school teacher with more than 13 years of experience, says it can be difficult to create engaging course work that's applicable to the challenges students face. "I think that sometimes, teachers don't know where to begin. Teachers are always looking for ways to make learning in their classrooms more relevant."

So what resources do teachers turn to in an increasingly fractured world? "Joining a professional learning network that supports and challenges thinking is one of the most impactful things that a teacher can do to support their own learning," Anglemyer says.

A new program for teachers that offers this network along with other resources is the WE Teachers Program, an initiative developed by Walgreens in partnership with ME to WE and Mental Health America. WE Teachers provides tools and resources, at no cost to teachers, looking for guidance around the social issues related to poverty, youth violence, mental health, bullying, and diversity and inclusion. Through online modules and trainings as well as a digital community, these resources help them address the critical issues their students face.

Jessica Mauritzen, a high school Spanish teacher, credits a network of support for providing her with new opportunities to enrich the learning experience for her students. "This past year was a year of awakening for me and through support… I realized that I was able to teach in a way that built up our community, our school, and our students, and supported them to become young leaders," she says.

With the new WE Teachers program, teachers can learn to identify the tough issues affecting their students, secure the tools needed to address them in a supportive manner, and help students become more socially-conscious, compassionate, and engaged citizens.

It's a potentially life-saving experience for students, and in turn, "a great gift for teachers," says Dr. Sanderlin.

"I wish I had the WE Teachers program when I was a teacher because it provides the online training and resources teachers need to begin to grapple with these critical social issues that plague our students every day," she adds.

In addition to the WE Teachers curriculum, the program features a WE Teachers Award to honor educators who go above and beyond in their classrooms. At least 500 teachers will be recognized and each will receive a $500 Walgreens gift card, which is the average amount teachers spend out-of-pocket on supplies annually. Teachers can be nominated or apply themselves.

One of the major differences between women and men is that women are often judged based on their looks rather than their character or abilities.

"Men as well as women tend to establish the worth of individual women primarily by the way their body looks, research shows. We do not do this when we evaluate men," Naomi Ellemers Ph.D. wrote in Psychology Today.

Dr. Ellers believes that this tendency to judge a woman solely on her looks causes them to be seen as an object rather than a person.
