By analyzing light curves—charts showing changes in brightness over time—from microlensing events, they noticed something surprising. These far-out planets don’t appear randomly.

Phase-curve observations can continue while the planet is eclipsing its star. While it was observing the phase curve of WASP-76B, CHEOPS saw a pre-eclipse excess of light on its night side. This ...

It zoomed around measuring the light from different stars. Then, scientists made light curves and looked for exoplanets. So far, scientists have found more than 5,500 exoplanets.

NASA's Planet Hunters TESS project invites the public to classify exoplanet light curves from TESS online. Another project, Exoplanet Watch, allows citizen scientists to gather data about known ...

It takes detailed analysis to find them. Exomoon light curves are much fainter than exoplanet light curves. Since they're so faint, noise in the signal can obscure them or even present false signals.

Researchers identified the likely planetary candidate’s infrared light after blocking out its host star’s overwhelming glare ...

Standard practice is to use the differential photometry method — measuring the difference in brightness between a variable star and a comparison star to construct a light curve of the variable.

Thousands of exoplanets have been discovered since the 1990s, including "hot Jupiters," "super-Earths" and other types of alien worlds.

Exoplanets can also leave traces in the light curve. If an exoplanet passes in front of its star as seen by an observer, it dims the starlight. This is reflected in the light curve as a regularly ...

What they came up with is a collection of light curves that shows what different VREs might look like on Earth-like exoplanets in different stages of atmospheric evolution around different stars.
