This week's science news saw us looking deep into the cosmos and the depths of our oceans. To understand the universe today, we need to look back at its earliest epoch, a period about 13 billion years ago known as the cosmic dawn. Until now, space-based telescopes have been our only way to peer back this far, but this week astronomers detected traces of light left by the first stars using a ground-based telescope — a feat scientists previously thought was impossible.

Astronauts Butch Wilmore and Suni Williams lifted off from Florida's Cape Canaveral Space Force Station on June 5, 2024, but not long into the mission helium leaks, along with a number of other issues, were discovered on their Boeing Starliner spacecraft.

There are so many mysteries about who or what might live among the stars, and whether they are advanced planet-hopping civilizations or microbes quietly doing what microbes do on a nearby moon.
