In 1437, Korean scientists watched a star go nova. Modern scientists finally found it.

As any historian of medieval East Asia or player of Civilization V: Brave New World will tell you, 15th century Koreans were really, really, really good at science.

Under the judicious rule of Sejong the Great, the kingdom's top researchers spent a lot of time looking at space and making maps of it.

In 1437, during one of these looking sessions, a bunch of scientists thought they discovered a bright new star, one that easily outshone everything else in the sky (eat it, Luyten 726-8A).

14 days later, it disappeared.

Unbeknownst to the ancient sky-watchers, the "new star" was not new at all. It was, instead, what's known as a "classical nova" — an ultra-dense, white dwarf star that sucks so much matter off a neighboring star it causes a giant, nuclear explosion. The star gets super bright for a short period of time before once again fading into the cosmic background — like a stellar version of Pokémon GO.

The problem is, 15th century Korean scientists didn't exactly keep the best records. For starters, it was the 15th century, and pretty much everyone had rickets. Also, the modern Korean alphabet wouldn't be invented for another seven years.

You'll be shocked to learn the location of the star that went nova was lost to time.

Until now.

After 580 years of searching, a team of researchers from four continents has finally located the star, making it the oldest such nova to have its location accurately documented.

Lead researcher Michael Shara had spent nearly 30 years looking for remnants of the stellar explosion, known as Nova Scorpii. (A great name for any Dutch speed metal band that might be looking, btw. Don't sleep on it!)  

Shara told The Atlantic's Marina Kornen that attempting to locate the site had been like "searching for a needle in a billion haystacks." Initially, the American Museum of Natural History curator and his team believed they'd find the nova between two stars in the constellation Scorpio. With the aid of online astronomical catalogs, which weren't a thing the first time Shara looked back in the 1980s, the astronomers combed through records of hundreds of millions of stars until, eventually, they focused in on a planetary nebula near the original search area.

In a classic "That's no moon, it's a space station" moment, the team rapidly realized that the nebula was the nova — or at least the remnants of it. They had been looking between the wrong two stars the entire time.

The team published its findings in the August edition of Nature.

"When we relaxed our criteria as to where to look in the constellation, we found the nova in 90 minutes," Shara told Space.com.

This 2016 image, taken by a telescope in Chile, shows the star — indicated by two long, red hashmarks — surrounded by the cloud of hydrogen it ejected in 1437. The smaller red "plus sign" in the center shows the star's location at the time it went nova almost six centuries ago.

Thanks to research by Shara and others, we know a lot more about novas than we did in 1437 — and even more now that Nova Scorpii has been tracked down.

In addition to classical novas, astronomers have observed frequent "dwarf novas" — much smaller explosions — across the visible universe. Shara has long suspected that both types of novae arise from the same star systems at different points in time rather than from different systems altogether.

Images from the 1930s and '40s, published in the paper, show the star pair that produced the 1437 nova undergoing a series of dwarf novae — lending Shara's theory some weighty backup.

Whether you specifically care about the dynamics of matter exchange in binary star systems of not, it's hard to deny that — holy crap — this is amazing.

When those 15th century Korean astronomers looked at the sky, they knew they were witnessing something important about their universe.

With the right tools, some tenacity, and a bit of luck, human beings have made it possible to find out what that is. Even after a 600-year search.

Science, then, as now, totally rules.

Expert says there's only one laundry cycle you ever need, no matter what's being washed

Straight from Patric Richardson, the "Laundry Guy" himself.

Because who can keep up with which laundry settings is for which item, anyway?

Once upon a time, our only option for getting clothes clean was to get out a bucket of soapy water and start scrubbing. Nowadays, we use fancy machines that not only do the labor for us, but give us free reign to choose between endless water temperature, wash duration, and spin speed combinations.

Of course, here’s where the paradox of choice comes in. Suddenly you’re second guessing whether that lace item needs to use the “delicates” cycle, or the “hand wash” one, or what exactly merits a “permanent press” cycle. And now, you’re wishing for that bygone bucket just to take away the mental rigamarole.

Well, you’re in luck. Turns out there’s only one setting you actually need. At least according to one laundry expert.

While appearing on HuffPost’s “Am I Doing It Wrong?” podcast, Patric Richardson, aka The Laundry Evangelist, said he swears by the “express” cycle, as “it’s long enough to get your clothes clean but it’s short enough not to cause any damage.”

Richardson’s reasoning is founded in research done while writing his book, “Laundry Love,” which showed that even the dirtiest items would be cleaned in the “express” cycle, aka the “quick wash” or “30 minute setting.”


Furthermore the laundry expert, who’s also the host of HGTV’s “Laundry Guy,” warned that longer wash settings only cause more wear and tear, plus use up more water and power, making express wash a much more sustainable choice.

Really, the multiple settings washing machines have more to do with people being creatures of habit, and less to do with efficiency, Richardson explained.

“All of those cycles [on the washing machine] exist because they used to exist,” he told co-hosts Raj Punjabi and Noah Michelson. “We didn’t have the technology in the fabric, in the machine, in the detergent [that we do now], and we needed those cycles. In the ’70s, you needed the ‘bulky bedding’ cycle and the ‘sanitary’ cycle ... it was a legit thing. You don’t need them anymore, but too many people want to buy a machine and they’re like, ‘My mom’s machine has “whitest whites.”’ If I could build a washing machine, it would just have one button — you’d just push it, and it’d be warm water and ‘express’ cycle and that’s it.”

When was the last time you washed you washing machine? "Never" is a valid answer.

According to Good Housekeeping, there are some things to keep in mind if you plan to go strictly express from now on.

For one thing, the outlet recommends only filling the machine halfway and using a half dose of liquid, not powder detergent, since express cycles use less water. Second, using the setting regularly can develop a “musty” smell, due to the constant low-temperature water causing a buildup of mold or bacteria. To prevent this, running an empty wash on a hot setting, sans the detergent, is recommended every few weeks, along with regularly scrubbing the detergent drawer and door seal.

Still, even with those additional caveats, it might be worth it just to knock out multiple washes in one day. Cause let’s be honest—a day of laundry and television binging sounds pretty great, doesn’t it?

Supportive husband writes a fantastic 'love list' to his depressed wife

“He knows I struggle to see good in the world, and especially the good in myself. But here it is."

Image from Imgur.

Husband shares a list of love with his wife.

Imgur user "mollywho" felt her life was falling apart. Not only was she battling clinical depression, but she had her hands full.

"I've been juggling a LOT lately," she wrote on Imgur. "Trying to do well at work. Just got married. Couldn't afford a wedding. Family is sparse. Falling out with friends, yaddadyadda.”

She was also upset about how she treated her new husband.

"I've not been the easiest person to deal with. In fact, sometimes I've lost all hope and even taken my anger out on my husband."


When she returned home from a business trip in San Francisco, mentally exhausted, she collapsed on her bed and cried. Then she noticed some writing on the bedroom mirror. It was a list that read:

Reasons I love my wife

1. She is my best friend
2. She never quits on herself or me
3. She gives me time to work on my crazy projects
4. She makes me laugh, every day
5. She is gorgeous
6. She accepts the crazy person i am
7. She's the kindest person i know
8. She's got a beautiful singing voice

9. She's gone to a strip club with me
10. She has experienced severe tragedy yet is the most optimistic person about humanity i know
11. She has been fully supportive about my career choices and followed me each time
12. Without realizing it, she makes me want to do more for her than i have ever wanted to do for anyone
13. She's done an amazing job at advancing her career path
14. Small animals make her cry
15. She snorts when she laughs

love letters, support, marriage, mental illness

The list of love.

Image from Imgur.

This amazing show of support from her husband was exactly what she needed. "I think he wanted me to remember how much he loves me," she wrote. "Because he knows how quickly I forget. He knows I struggle to see good in the world, and especially the good in myself. But here it is. A testament and gesture of his love. Damn, I needed it today…"

She ended her post with some powerful words about mental illness.

"I'm not saying mental illness is cured by nice words on a mirror. In fact, it takes professional care, love, empathy, sometimes even medication just to cope. Many people struggle with it mental illness - more than we probably even realize. And instead of showing them hate or anger when they act out. Show them kindness and remind them things can and WILL get better. Everyone needs a little help sometimes. If that person can't be you - see if you have any resources for therapy."

Nicole Kidman shares the unconventional marriage rule she has with husband Keith Urban

They've had this communication rule since the very beginning of their 18 year relationship.

Wikipedia

Keith Urban (left) Nicole Kidman (right)

Long before Nicole Kidman began her long-term relationship with AMC theaters, she was committed to husband and country singer Keith Urban. The two have happily been together since 2006—which is a good run for any modern day marriage, but most certainly a Hollywood one.

And perhaps their nearly decades-long success can be partially attributed to one surprising communication rule: no texting.

While appearing on the Something To Talk About podcast in 2023, Kidman shared that she was the one who initiated the unconventional agreement.

"We never text each other, can you believe that? We started out that way – I was like, 'If you want to get a hold of me, call me…"I wasn't really a texter.,” the “Moulin Rouge” actress shared.

She added that while Urban did attempt texting her a few items early on, he eventually switched when Kidman wasn’t very responsive. And now, 18 years later, they only call each other.

“We just do voice to voice or skin to skin, as we always say. We talk all the time and we FaceTime but we just don’t text because I feel like texting can be misrepresentative at times…I don’t want that between my lover and I,” she told Parade

.

There are, of course, some pros and cons to calling over texting. Research has shown that people who call feelmore connected to one another vs. texting, with the voice being an integral component of bonding. As our society becomes increasingly more distant and lonely, finding those moments might be more important than ever.

At the same time, calling can invoke a lot more anxiety compared to texting, which could lead someone to not communicating at all. Also, I don’t know about you, but the thought of having to call my partner for mundane things like “don’t forget the eggs” would drive me crazy.

But regardless of whether or not you adopt Kidman and Urban’s no-texting rule, perhaps the bigger takeaway is that relationship longevity depends on being able to establish your own rules. One that feels good and that each partner is able to stick to. Especially when it comes to communication.

As Urban himself told E! News at the CMT Music Awards, "I have no advice for anybody,You guys figure out whatever works for you…We're figuring it out. You figure it out. Everybody's different. There's no one size fits all."

Luckily, there are many ways to have good text hygiene, without having to do away with it completely. Very Well Mind suggests to avoid texting too many questions, and to be respectful of your partner's schedule (probably best to not text them while they’re sleeping just to say “hey,” for example). Nor should texting be used to argue or deal with conflict. Lastly, probably save the lengthy, in-depth conversations for a phone call. Fifteen heart emojis are totally fine though.

Most pregnant women know what they need to bring to the hospital. Doris' list had something extra.

For Doris, the list was very different.

Bathrobe. Socks. Insurance card. Snacks.

Sound at all familiar? Maybe, maybe not.

These items would commonly be found on a checklist of things that expecting parents should bring to the hospital with them — in the U.S., anyway.

But what is that list like in other parts of the world?

For Doris, that list included water.

Doris, who lives Morogoro, Tanzania, had to bring her own water to the health center where she was giving birth in 2014. The water she brought was used to clean the nurse's hands, clean the delivery area, and wash the babies (she had twins!). Unfortunately, the water Doris brought ran out before she was able to wash herself or her clothes, so she had to wait 24 hours before cleaning herself.

I'll let Doris tell the story herself:

Lack of access to clean water in Tanzania is a very big deal.

Everything turned out alright for Doris and her babies, but thousands of other women aren't as lucky. But there are ways to help: Organizations and individuals are pitching in to help build water taps, rainwater tanks, and latrines in Tanzanian hospitals, and they're making a huge difference.

"I want to express my gratitude to the health workers ... because they have a great sense of humor with the patients. But the problem is the availability of enough water." — Doris Alikado

9 astounding photos this mom took to keep herself calm while giving birth.

Birth is intense. It's also beautiful.

Lisa Robinson/Lisa Robinson Photography.

New baby and a happy dad.


When San Francisco photographer Lisa Robinson was about to have her second child, she was both excited and nervous.

Sure, those are the feelings most moms-to-be experience before giving birth, but Lisa's nerves were tied to something different.

She and her husband already had a 9-year-old son but desperately wanted another baby. They spent years trying to get pregnant again, but after countless failed attempts and two miscarriages, they decided to stop trying.

Of course, that's when Lisa ended up becoming pregnant with her daughter, Anora. Since it was such a miraculous pregnancy, Lisa wanted to do something special to commemorate her daughter's birth.

So she turned to her craft — photography — as a way to both commemorate the special day, and keep herself calm and focused throughout the birthing process.

Normally, Lisa takes portraits and does wedding photography, so she knew the logistics of being her own birth photographer would be a somewhat precarious new adventure — to say the least.

She initially suggested the idea to her husband Alec as a joke.

"After some thought," she says, "I figured I would try it out and that it could capture some amazing memories for us and our daughter."

In the end, she says, Alec was supportive and thought it would be great if she could pull it off. Her doctors and nurses were all for Lisa taking pictures, too, especially because it really seemed to help her manage the pain and stress.

In the hospital, she realized it was a lot harder to hold her camera steady than she initially thought it would be.

"Eventually when it was time to push and I was able to take the photos as I was pushing, I focused on my daughter and my husband and not so much the camera," she says.

"I didn't know if I was in focus or capturing everything but it was amazing to do.”

The shots she ended up getting speak for themselves:

"Everybody was supportive and kind of surprised that I was able to capture things throughout. I even remember laughing along with them at one point as I was pushing," Lisa recalled.

In the end, Lisa was so glad she went through with her experiment. She got incredible pictures — and it actually did make her labor easier.

Would she recommend every mom-to-be document their birth in this way? Absolutely not. What works for one person may not work at all for another.

However, if you do have a hobby that relaxes you, figuring out how to incorporate it into one of the most stressful moments in your life is a pretty good way to keep yourself calm and focused.

Expecting and love the idea of documenting your own birthing process?

Take some advice from Lisa: "Don't put pressure on yourself to get 'the shot'" she says, "and enjoy the moment as much as you can.”

Lisa's mom took this last one.
