We frequently question whether we are alone in the universe.
The Wolf Moon is named for the hungry predators that sometimes can be heard howling in the winter month.
Earthquake sensors can detect sonic booms generated by reentering space debris to help track the potentially dangerous objects in near real time.
We live near a fusion reactor in space that provides all our heat and light. That reactor is also responsible for the creation of various elements heavier than hydrogen, and that's true of all stars. So, how do we know that stars are element generators? Many clues lie hidden in stellar spectra, since they contain fingerprints of various elements cooked up by the stars.
"Stars like the sun don’t just stop shining for no reason."

Some galaxies in the early universe were absolute powerhouses, churning out stars at rates that would dwarf the Milky Way's modest stellar production.

But what drove them to grow so violently has remained frustratingly unclear.
A team of predominantly Canadian researchers are using massive galaxy clusters and the JWST to study low-mass galaxies from 13.5 billion years ago all the way up to 5 billion years ago. The clusters are used as gravitational lenses to expand the JWST's reach. It's called CANUCS, the Canadian NIRISS Unbiased Cluster Survey.
