good evening. thank you for joining us. tonight, high stakes in the biggest abortion case in more than two decades. we're inside the very human efforts on both sides of the debate. as many look to make the crucial difference in a legal decision that could impact millions of lives. here's abc's gloria riviera. >> reporter: separated by just a few feet, but they stand a world apart. today outside the supreme court, passions inflamed on both sides

culture war. while inside, the most important abortion case being considered in a generation. >> improve patient safety. that's what these laws have always been about. >> they won't promote women's health. they are going to make abortion less safe. >> reporter: arguing that controversial texas law that regulates abortion clinics as unconstitutional is stephanie toady. it's her first time at the nation's highest court. but with her, some star power support. >> i realize the next generation may have less choice than i did. >> reporter: judging amy and leftovers actress amy breneman and 40 other women lent their name to the cause, saying that having an abortion allowed them to have happier, healthier lives. >> i was 21. it was after my junior year. >> reporter: this week, she opened up in this emotional video posted to youtube.

in place that i wasn't "reshaping it all"ed shape med and i was supported. if you start delving into your family and friends, you're going to find a woman who's terminated a pregnancy. so, therefore, it's in everybody's life. and i draw the line for whitney. >> reporter: believes restrictions around the country are going too far, she's joined forces with other celebrities in the draw the line campaign. >> i'm elizabeth banks, and i draw the line for rebecca. >> reporter: encouraging women to share their stories about how abortion helped them instead of hurting them. this is not the first campaign of its kind. >> i had an abortion last year. it was an incredibly positive experience for me because i didn't want to become a mother. >> reporter: last year, amelia decided to share her story on facebook. and giving it a hashtag shoutmyabortion, and it went viral. >> plenty of people still believe that on some level, if you're a good woman, abortion is

accompanied by sadness, shame, or regret. but i have a good heart, and having an abortion made me happy in a totally unqualified way. >> reporter: she says she was not surprised by the outpouring because one in three women in this country have had an abortion by the age of 45, according to one study. >> within a couple of hours, there were women in and out of my social circle that were just saying, hey, i had an abortion too. >> i think the shout your abortion campaign is phenomenal. i love it. >> reporter: they have taken it personally. >> look at you! >> martha plimpton also shared she had a positive experience. for me in particular, because i did have two abortions as a young woman, i feel that my ability to access that kind of medical care made it possible for me to live out my dreams and do what i really wanted to do with my life. >> reporter: among other restrictions, the texas law requires that abortion clinics are more like surgical centers, and that doctors have admitting

>> you want to be a health care provider, then act like it. that's what we're saying. >> reporter: critics of the law say adhering to the new standards make it impossible for many abortion providers to remain open. especially in a state the size of texas. >> millions of women in texas and other states across the region are at risk of losing their constitutional right to access safe abortion care. >> reporter: millions of women. the ripple effect could be huge. >> absolutely. we have seen copycat laws in other states in the south. >> reporter: and since the law was enacted, half of the abortion clinics in texas have closed. what kind of personal stories are you hearing? >> stories about women having to travel out of state because the waits for an appointment with an abortion provider in texas have become so long. >> reporter: in a new documentary, "trapped," doctors and nurses at whole women's

abortion clinics that's challenging, shares stories about how they had to turn away women in need. >> there's a two to three-week waiting list for a procedure where time is of the essence. >> i remember getting a call from a patient and said, what if i tell you what i have in my kitchen cabinet, and you tell me what i can do. >> reporter: but those on the other side of the issue say that the texas law and others like it are designed to protect women's health. anti-abortion activists also submitting briefs to the court, citing 3,000 women who they say suffered grievous psychological injuries after their abortions. >> a majority of americans, regardless of whether they say they are pro-life or pro choice on the issue of abortion, agree that abortion should be safe for women. >> reporter: kristen hawkins is presidents for students for life of america and has recruited thousands to the cause. >> today we have come out to show the supreme court justices that this is a pro-life

my mission is to abolish abortion. and to make abortion unthinkable and illegal. >> reporter: she thinks the stricture regulations on abortion clinics across the nation are just the first step. >> we're a pro-life generation! >> reporter: we were with the young mother last year at one of the largest ever anti-abortion demonstrations. this is what the pro-life movement looks like at its strongest in the united states today. we're at the march for life. and what you see behind me goes on for miles. >> today i speak to you pregnant with my fourth child. my first daughter. we are the pro-life generation! >> reporter: to some, like 16-year-old devin, she's a hero. life? adoption?

i wanted to have an abortion when i found out i was pregnant with my daughter. and i was given the options that i could do abortion and not tell anyone, or i could leave home. i went to a maternity home and in october i placed my daughter for adoption. and because of her, i'm not ashamed i got pregnant at my age anymore. >> reporter: hawkins regularly conducts what she calls sidewalk counselling outside planned parenthood clinics with student volunteers like sam from the university of new mexico. >> whenever i sidewalk cancel, it's usually in a back alley on top of a ladder so we can reach the women. >> reporter: but the young women on the other side, women who could be her class mates, are just as dedicated. many feel that the greatest danger is to women, forced to turn to illegal, unsafe alternatives if the texas law is upheld. >> since these laws have taken effect, there's been an increase in attempts at self-induced

because they simply can't make the trip that is now required in order to reach an abortion clinic. >> reporter: but for now, stephanie has done what she can. the case rests in the hands of the eight remaining justices. >> abortion is a human right! >> reporter: but no matter the ruling, we'll likely see this scene play out again and again. >> pro women, pro-life! >> reporter: this battle isn't ending anytime soon. for "nightline," i'm gloria riviera in washington, d.c. next -- "modern family" star ariel winter opening up about why she chose to have a breast reduction. and later, astronaut scott kelly returns home. science experiment now comparing him to his own twin brother. there's no such thing as a little flu. and it needs a big

"modern family" star ariel winter grew up in the limelight, facing harsh criticism constantly. now she is speaking candidly about her breast reduction surgery and opening up about what she says was a troubling childhood. >> i'm not. one. >> reporter: we fell in love with her as alex dunnphy, the family." >> ha beating me in words with friends. how is that possible? >> reporter: we watched her grow up on screen from an 11-year-old girl to an 18-year-old woman. and just last year, when she was

undergo breast reduction surgery going from a 32f to a 32d. why did you decide ultimately to get breast reduction surgery? >> i had wanted to get a breast reduction since i developed, because i was in excruciating pain, and i couldn't sit up straight. it was always super uncomfortable for me to sleep. it's uncomfortable to sit. uncomfortable to walk. i remember breaking down in dressing rooms because i couldn't find a bathing suit because they had no top that would fit me. i just didn't feel right. and i did it for myself. it was the best change i ever made in my life. >> what's been the most noticeable change post surgery for you? >> i think maybe my mood. in general. i think i'm just much happier. and i just feel a lot more secure with myself. >> reporter: you're lighter in every way. >> exactly. >> reporter: you wore's a stunning gown to the sag awards, and you were not afraid to show your scars. >> no, i wasn't. i didn't even notice them. i didn't think to cover them. i didn't even think twice.

was getting comments from people to say put my scars away, they were gross. and i think it's so ridiculous considering they are a part of me. they're not going away. i know so many people that have scars, and there's nothing wrong with scars. >> reporter: scars are cool. i've got them too. >> they are cool. we've got stories from them. >> reporter: although she's young, winter says she's already had a lifetime of challenging experiences. you were thrust into the limelight at a very young age. were you prepared for what came with that? >> i don't think anyone's prepared to be so young and having everybody's eyes out, especially now as i've gone through some of my really -- some really big moments in my life being in front of the spotlight. it has been pretty difficult, opinions. so i think it was a little beginning. >> reporter: part of that shock was from the public scrutiny. online bullying and body shaming she experienced. >> walking down the red carpet and having every headline be

my talent and what i was really there for or anything that i wanted to be put out there. and i thought that was really disappointing. >> reporter: just the fact that we're sitting here discussing your decision, and what went into deciding whether or not to have breast reduction surgery, i mean, is it crazy to you that the level of scrutiny girls and women face each and every day, especially those in front of the camera? >> i think it's absolutely ridiculous. it really bothers me. but, you know, i can only do my part. >> reporter: she's hoping her experience will help other girls, and wishes for a day when women in hollywood are no longer scrutinized for their looks. but despite her success as an actress, she says it's a path she might never have chosen. >> i think that when i was born, it was kind of already decided what i was expected to be. and so i was kind of pushed into the industry. that's not to say i don't love it and it's not my passion now. i do love it. >> reporter: her work as an actress started when she was just 4 years old. from there, the tv roles came one after another, guest

>> she says he didn't love us. >> come on, sweetie. wake up. minds." >> i want to find my mommy. i like living there. >> reporter: she even appeared on the final six episodes of "e.r." as a girl whose mother needed a heart transplant. since. >> reporter: did you have what most people would say is a stage mom? >> she most definitely was. this is what she wanted me to do. that. and kind of put that in the forefront of her mind instead of what i wanted and what i needed. and that was definitely hard. but i don't think that was the only issue. >> reporter: winter went through several years of legal battles with her mom over allegations of emotional and physical abuse. in a statement to abc news, winter's mother said to further her career, ariel is conjuring up stories, and i deny all of ariel's accusations.

emancipated from her mother. >> it wasn't a supportive, loving home. i had a really tough time. >> reporter: winter is not the only kid star who emancipated herself from a parent. "home alone" actor macaulay culkin did it after a financial dispute and custody battle. and then there was actress drew barrymore, who emancipated at 14. according to her memoir, she and her and /- her mother haven't had much contact since. do you have a relationship with your mom at this point? >> we haven't spoken in three years. it's really hard to have that kind of drama in your life and have an open court case and have everybody look at it. it's hard for abuse victims, but it's harder in the public eye when everybody has an opinion and there is no black and white of the situation. >> reporter: you refer to yourself as an abuse victim. what happened to you? >> well, the thing is it's really hard to talk about. and the reason i haven't talked about it thus far is because it

watch my mom go on news outlets and go on "dr. phil" and kind of spread things everywhere when it's really just private family business. i feel like for me, i probably should take the high road and do something that i would have wished she would have done for me. >> reporter: and for now, she's closing that chapter and doing normal 18-year-old things. >> it's always been a dream of mine to go to college. >> reporter: she's applying to colleges with plans to become a social justice lawyer. >> i've had a lot of life experience that i think has really helped me grow into the person i am today. and i think it's something that shaped what i wanted to be in my future. >> reporter: for "nightline," i'm amy orrback in los angeles, california. scott kelly returns home. could the answer to growing taller and younger be here, spinning in space? abc news "nightline" brought

finally tonight, astronaut scott kelly is back on earth, proving it may just take a rocket scientist to find the fountain of youth. here's abc's david wright. >> reporter: 340 days after he slipped the surly bonds of earth, scott kelly is finally home. overnight, his soyuz capsule splashed down in kazakhstan, kelly testing the earth's gravity with a fist pump. >> i felt like i had been up there my whole life. >> reporter: in an odd way, he has.

circled the earth more than 500 times. that's 15 years of sunrises. you could say that now makes him 15 years older than his identical twin brother, retired astronaut mark kelly. but albert einstein would argue the opposite. einstein's twin paradox maintained that a twin hurtling through space on a rocket ship would age more slowly than the twin remaining on earth. another difference, scott is now apparently two inches taller, his spine likely stretched while he was in orbit. nasa will now be studying that, comparing the two. all of which may sound like a sci-fi movie, and it's tempting to think of scott kelly a bit like another fictional astronaut. >> back home. you blew it up! >> reporter: a year ago the super tuesday results would have been as unthinkable as -- well, the planet of the apes.

>> reporter: in a year, the blink of an eye, the unthinkable has come to pass. >> thank you very much. i appreciate it. >> reporter: how ust must it look to the rocket man? i'm david wright for "nightline" in new york. >> welcome home, captain kelly. it was a french writer andre geed who said, men cannot discover new oceans unless he has courage to lose sight of the shore. thank you for watching. tune in to "good morning america" tomorrow morning. and as always, our facebook "nightline" page and abcnews.com. good night, america. >> can i guarantee that
