A potentially catastrophic asteroid impact may seem like science fiction, yet the possibility remains real. Earlier this year, asteroid 2024 YR4 briefly raised alarms with a 1-2 percent chance of colliding with Earth in 2032. Although updated calculations have ruled out a threat in this instance, future threats remain a pressing concern.

The vast majority of matter in the universe is dark-it is entirely invisible and detected only through its gravitational effects. Ordinary matter-everything from protons to planets to people-makes up only 16 percent. Unlike dark matter, ordinary matter emits light of various wavelengths and thus can be seen. But a large chunk of it is diffuse and spread thinly among halos that surround galaxies

The Big Bang is often described as the explosive birth of the universe - a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else - something more familiar and radical at the same time?

Astronomers have successfully traced the bulk of the Universe's "missing" ordinary matter to the intergalactic medium, using fast radio bursts (FRBs) as cosmic probes. Researchers from the Center for Astrophysics | Harvard and Smithsonian and Caltech leveraged these powerful signals to detect the faint, elusive gas long suspected to float between galaxies, finally providing a detailed census of
