Standardizing and improving models used in astrobiology

Until last fall Amber Young was a NASA astrobiologist seeking signs of life on the more than 6,000 planets discovered beyond our solar system. She is fascinated by exoplanetary atmospheres and the signatures in them that offer clues that organisms might exist somewhere on those worlds. “Life changes the atmosphere,” she says. Now in her new role as a NASA project scientist, she calls shifts in atmospheric composition “the loudest way” life makes its presence known.
Even though she’s not actively searching for life these days, she still conducts research on the side. She is leading a volunteer effort to cross-compare exoplanet-modeling tools that astrophysicists use for exoplanet characterization. “I am really invested in the search for life elsewhere,” she says. “It’s not just what I do; it’s who I am.” To that end, she has crunched numbers for the early planning stages of NASA’s Habitable Worlds Observatory, a flagship space telescope the agency hopes to launch in a decade or so to bring rocky worlds orbiting sunlike stars into our investigative reach. She still feels like part of the mission to get HWO into space.

From the excitement of an astronomy section in sixth-grade science to an early research project on methane in the Martian atmosphere, this first-generation college graduate’s interests have pushed into deeper space while remaining grounded in what Earth can teach us. Life could mean a lot of things, Young says. Considering the entire history of what has existed on Earth is critical to making sure we don’t miss some small clue on another planet as a signal that we are not alone. Earth has “presented multiple flavors of life as we know it,” she says. And Young is eager to see which flavors are universal.

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
