"This is one of my biggest astrophotography accomplishments to date, and the largest panorama I have ever captured, with the full resolution image containing over a billion pixels from 62 images stitched together. I had envisioned this composition for a long time, capturing the twin glacial rivers with the Milky Way core off to the left of the image, as well as the famous Southern Cross and other pointers high in the centre sky."

"During a routine time-lapse observation of the solar chromosphere [the thin, reddish layer of the Sun’s atmosphere above the visible surface], I captured a serendipitous moment when an aircraft crossed the field of view. Preserving this transient frame, I employed multiple blending modes to enhance the details of the solar background. Beyond stacking individual video frames, I processed the sequence, undertook colour inversion and synthesised 100 images through combined mean and minimum blending. This dual approach effectively accentuated both bright plages [active regions in the chromosphere] and dark laments through enhanced contrast. "The composite image reveals the evolution of the Sun’s dynamic surface across a two-hour observational period, while the aircraft’s two-second transit remains frozen in time. This layered imaging rearranges time, blending celestial bodies and human technology in one photo."

Gregory Costa Cuautle: microlensing (a super useful, if terribly unsatisfying, technique for exoplanet detections). Measuring the center of light, not just the brightness, helps break degeneracies in planet size/distance from star and source vs. lens.

What about exomoons? Nancy Grace Roman Telescope should be able to find certain star-planet-moon configurations, but more simulations needed.

He's an undergrad! That was a great talk!

A small image of a galaxy distorted by gravitational lensing into a dim ring. At the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other: these are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens. In the centre of the ring, the elliptical galaxy doing the lensing appears as a small blue dot. The background is black and empty.
