Astronomers have found a special population of dwarf galaxies that could mainly consist baryons within radii of up to tens of thousands of light-years. This contrasts with the normal expectation that such regions should instead be dominated by dark matter.

Because we don't know what's pushing the universe outward ever more quickly, 'dark energy' is scientists' shorthand for the mysterious process. To understand the history of our universe, researchers are collaborating with scientists around the globe to build elaborate 3D maps of space and time.

A team of astronomers proposes a new method of using Webb to determine whether a rocky exoplanet has an atmosphere. The technique, which involves measuring the planet's temperature as it passes behind its star and then comes back into view, is significantly faster than more traditional methods of atmospheric detection like transmission spectroscopy.

Astrophysicists modeled a theoretical twin of Earth into other star systems called binary systems because they have two stars. They concluded that 87% of exo-Earths one might find in binary systems should have axis tilts similarly steady to Earth's, an important ingredient for climate stability that favors the evolution of complex life.
