Science
A planet crosses a distant star. A star begins to pulse.
We turn tiny changes in light into clues about the universe.
The universe
leaves a signal.
A telescope can do more than reveal a distant object. It can measure how that object changes. Our mobile observatory is being developed to turn nights under Hawaiʻi’s skies into precise records of starlight.
NASA Exoplanet Watch methods
A world hidden
in a flicker.
A planet passing in front of its star blocks a little of the light. Measure that tiny dip, exposure after exposure, and a world begins to reveal itself. Repeated observations of known planets can refine when their next transits will happen.
AAVSO observing methods
Stars have a rhythm.
Some stars pulse. Others erupt or dim as a companion moves in front of them. Comparing a target with steady stars in the same field lets us trace those changes—and connect one night’s measurements to a much longer story.
A direction for our science program
Follow the next clue.
NASA’s TESS mission finds promising dips in starlight. A closer look from the ground helps establish which star is changing, improve transit timing, and investigate false positives. We are developing the capability to take part in that kind of follow-up.
From photons
to a light curve.
The science comes from a careful, repeatable process—one exposure at a time.
Track.
Equatorial tracking and autoguiding keep the same star field steady through the night.
Collect.
Cooled astronomy cameras record a timed sequence of exposures of the target and nearby stars.
Calibrate.
Correct camera signatures and compare the target’s brightness with reference stars.
Measure.
Plot brightness against time. The pattern reveals what changed—and when.
Come for the stars.
Stay for the questions.
On public nights, we reveal nebulae, galaxies, and clusters. Our developing science program takes the same curiosity further: turning the light we collect into measurements that can support research.
