Skyler Palatnick’s selection as a 51 Pegasi b Fellow is a big moment for ultraviolet exoplanet imaging and the hunt for biosignatures beyond our solar system. This article looks at his three-year postdoc at UCLA, the impact of metasurface optics on next-gen coronagraphy, and how all this might shape future missions to find life elsewhere.
51 Pegasi b Fellowship and Palatnick’s UCLA Program
The Heising-Simons Foundation just named eight new 51 Pegasi b Fellows. They support top postdocs in planetary astronomy, whether their research is theoretical, observational, or experimental.
Skyler Palatnick, a physics doctoral candidate from UC Santa Barbara, is heading to UCLA for a three-year postdoc focused on ultraviolet coronagraphy and metasurface optics. This fellowship aims to speed up bold ideas that could change how we study distant worlds and their possible signs of life.
At UCLA, Palatnick plans to push coronagraph technology into ultraviolet wavelengths. That’s a part of the spectrum we haven’t really explored for biosignatures, but it holds promise.
He’s working on lightweight, compact metasurface optics—practical components that could one day fit into NASA’s future Habitable Worlds Observatory. With these, we might get more sensitive and efficient UV observations of exoplanets.
Ultraviolet Coronagraphy: Opening a New Window on Biosignatures
Ultraviolet observations can spot chemical signatures linked to biology that visible or infrared instruments might miss. Palatnick wants to use metasurface technologies to block out starlight in the UV with sharp precision, so we can directly image faint exoplanets that would otherwise stay hidden.
He’s mixing theoretical modeling, hands-on fabrication, and planning for future observations to move UV coronagraphy from idea to reality. One of his main goals is to make lightweight, compact metasurface optics that space missions can actually use without adding a ton of weight.
If this works, ultraviolet coronagraphy could reveal spectral features and chemical pathways tied to life. It would give us clues that go beyond what infrared biosignature searches can offer.
Metasurface Optics: A New Era for Coronagraphs
Metasurfaces are silicon-based devices packed with billions of nanoscale posts. By changing the size and pattern of these posts, you can shape light in new ways.
They’re a programmable, scalable alternative to old-school liquid crystal coronagraphic masks. For research teams and space missions, metasurfaces offer real advantages.
Unlike traditional liquid crystal systems, metasurfaces cost less to make. Labs can iterate on them faster, trying out new designs quickly and cheaply.
This flexibility matters when you’re trying to perfect UV coronagraphic performance, whether you’re in the lab or getting ready for a launch. Metasurface coronagraphic elements can steer starlight away from the image center, creating the darkness we need to image faint exoplanets in UV light.
It’s a more realistic route to catching UV biosignature signals—maybe even hints of life—on distant worlds.
Advantages Over Traditional Techniques
- Cost reduction and simpler fabrication mean more labs and universities can join the cutting edge.
- Rapid design iterations help researchers test lots of metasurface setups quickly, so progress happens faster.
- Space-heritage potential comes with compact, lightweight optics that fit the limits of today’s and tomorrow’s observatories.
- UV compatibility opens up biosignature-relevant spectral bands—maybe the key to new planetary clues.
Collaborators, Impact, and Future Prospects
Palatnick’s advisor, Max Millar-Blanchaer, has played a big role in metasurface optics. His work helped open up this new field and gave researchers more ways to directly image exoplanets.
Millar-Blanchaer thinks Palatnick’s project could change how we design and use coronagraphs. The ripple effect could reach far—maybe even leading to the discovery of new worlds and the first real signs of life beyond Earth.
When you look ahead, pairing ultraviolet metasurface coronagraphy with big missions like the Habitable Worlds Observatory could totally change the biosignature search. If it pans out, we might get to ultraviolet exoplanet imaging faster, cheaper, and with more flexibility—finally closing some big gaps in our understanding of other planetary systems and the odds of life in the galaxy.
What This Means for the Search for Life Beyond Earth
The Palatnick project shows how innovative optics and interdisciplinary collaboration can push the boundaries of observational astronomy.
The ultraviolet window, paired with metasurface technology, might reveal hidden chemical signatures and help us spot worlds that deserve a closer look.
Researchers are testing new designs and moving toward mission-ready hardware. The field edges closer to a future where direct UV imaging could become a regular tool in the exoplanet toolkit.
