The most common planets in the galaxy don't appear around the most common stars, TESS observations suggest

Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new research from McMaster University reveals ...

Stellar flares may expand habitable zones around small stars

The search for life beyond Earth has traditionally focused on exoplanets orbiting sun-like stars, which is a G-type star. However, low-mass stars, which are designated as K-type and M-type stars, have rapidly become a target ...

Ocean bottom seismometers could improve earthquake warning times in Pacific Northwest

If there is a magnitude 8 or 9 megathrust earthquake off the coast of the Pacific Northwest, data from ocean bottom seismometers (OBS) could improve earthquake detection times calculated by the ShakeAlert system.

CHEOPS discovery defies planetary formation rules

We're starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA's CHEOPS mission places a rocky world ...
