You’re the dip in my light curve—proof that something incredible is in my orbit!
When a planet passes in front of a star, it causes a dip in brightness—a clear signal that something is out there. Our astronomers use this technique to detect and study exoplanets, searching for habitable worlds beyond our Solar System.

My world revolves around you.
Our scientists use world-class telescopes to study planetary motion and how gravitational forces shape planetary systems, deepening our understanding of the universe’s structure.

Are you a carbonaceous asteroid? Because I’d travel 200 million miles just to get a piece of you."
Our scientists studied samples from the asteroid Bennu to unlock clues about the building blocks of life—demonstrating that sometimes, a small piece of rock can hold big secrets! Credit: The line art of Osiris-REX was adapted from the NASA Astrobiology coloring pages.

Our love is like dark matter. It may be invisible, but it’s always there holding everything together.
Carnegie Science astronomer Vera Rubin provided the first evidence for dark matter’s existence by studying galaxy rotation. Today, our scientists continue this legacy, exploring the hidden forces shaping the universe.

Are you a black hole? Because I'm hopelessly drawn to you, and time stands still when I get too close."
Our astrophysicists are mapping the universe's black holes. These astrophysical phenomena are capable of warping spacetime.  Their gravity is so intense that time itself slows—just like when you’re completely captivated by someone special!

Were you born in a lab? Because you’re a model organism.
Our researchers use fruit flies as model organisms to study genetics and evolution. We're also pioneering a new coral model to better understand climate resilience in marine ecosystems.

Are we mutualistic symbiotes? Because I can’t live without you."
Our scientists study symbiosis, helping us understand how species rely on each other in ecosystems—just like the best relationships!

Our love is like photosynthesis—you light up my life and help me grow."
Photosynthesis powers all life on Earth, and our scientists study how plants and algae use this amazing process to convert sunlight into energy—just like the right person can inspire growth and renewal!

   "We go together like roots and rhizobia—you give me a home, and I help you grow!"
Our research on plant-microbe interactions helps improve agriculture and soil health, making farming more sustainable. 

You’re the photosynthetic algae to my coral—without you, I’d bleach, collapse, and become a ghost of my former self
Tiny photosynthetic algae live inside coral, providing energy and vibrant color. When ocean temperatures rise, corals expel these symbiotic algae, leading to bleaching and ecosystem collapse. Carnegie scientists study how climate change affects coral reefs and are developing a new coral model to better understand resilience in a warming world.

We use ion beams in NanoSIMS and mass spectrometers to analyze the chemical makeup of meteorites and rocks, revealing clues about planetary formation and Earth's history.

I’ll never take you for granite.
Our geochemists study rock formation and Earth's deep history, using materials like granite to unlock ancient planetary processes.

Have I told you lately that I lava you?
Our volcanologists study magma and planetary interiors, investigating how volcanic activity shapes our planet. 

I'm totally crushing on you
Carnegie scientists use diamond anvil cells to recreate the extreme pressures found deep inside planets, helping us understand planetary formation and the behavior of materials under these intense conditions. We also use these high-pressure devices to pioneer the creation of novel materials like diamond nanothreads.
