Finding Alien Worlds in Queensland — A Decade of MINERVA-Australis
Three decades ago, humanity entered the Exoplanet Era, with the discovery of the first planets orbiting other stars. Today, more than 6000 exoplanets are known – a tally recently bolstered […]

A Single Power Law For The TRAPPIST-1 Flare Distribution Across Four Orders Of Magnitude In Energy
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets’ high-energy irradiation environments, with consequences for atmospheric chemistry and escape, and they can contaminate transmission spectroscopy […]

JWST Unveils A High Mean Molecular Weight Atmosphere For Mini-Neptune TOI-1130b: Evidence For Formation Beyond The Water Ice Line
We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R⊕, 19.8 M⊕, Teq∼825 K). It is part of a rare and unique […]

Tatooine-Class Planet Discovered Orbiting Two Suns
There’s so little we know about circumbinary planets – planets that orbit two stars instead of one – that they can feel like the stuff of fantasy.

New Findings About Exoplanets Challenge Theories Of Planet Formation
Astronomers estimate there is at least one planet for every star in our galaxy. Called exoplanets, they orbit stars outside our solar system. But new research from McMaster University reveals […]
