Astronomers rule out one explanation for the Hubble tension
Perhaps the greatest and most frustrating mystery in cosmology is the Hubble tension problem. Put simply, all the observational evidence we have points to a universe that began in a hot, dense state, and then expanded at ...

If you account for the Laniakea supercluster, the Hubble tension might be even larger
One of the great unsolved mysteries of cosmology is known as the Hubble tension. It stems from our inability to pin down the precise rate of cosmic expansion. There are several ways to calculate this expansion, from observing ...

On its hunt for dark energy, a telescope stopped to look at the Lobster Nebula
If you thought dark matter was difficult to study, studying dark energy is even more challenging. Dark energy is perhaps the most subtle phenomenon in the universe. It drives the evolution of the cosmos, but its effects are ...

We can probably find supernovae enhanced by gravitational lensing, we just need to look
Gravitational lensing provides an opportunity to see supernovae and other transients much farther than we normally can. A new research proposal outlines a plan to use a comprehensive catalog of strong gravitational lenses ...
