Unlocking the Universe's First Secrets
Imagine holding a time-traveling telescope that lets you peek back over 13 billion years to witness the universe's very first moments. That's what scientists are doing with the study of the cosmic microwave background (CMB) - the afterglow of the Big Bang. This exploration is not just about satisfying our curiosity; it's about understanding the origins of everything around us, including the galaxies, stars, and even the very atoms that make up our bodies. By studying the first light, we're piecing together the universe's earliest chapters, which in turn helps us understand more about our place in this vast cosmic story. For you, this could mean exploring the ultimate frontier from your classroom or bedroom, connecting with the mysteries of the cosmos, and perhaps even inspiring a future career in science or technology.

Cosmic microwave background (CMB)
The afterglow radiation from the Big Bang, providing a snapshot of the infant universe.
Galaxy formation
The process by which dense regions within the universe become galaxies, involving the collapse of gas and dark matter under gravity.
Dark matter
A mysterious form of matter that does not emit light or energy, yet exerts gravitational pull, influencing the structure and evolution of the universe.
Photon
A particle representing a quantum of light or other electromagnetic radiation, carrying energy proportional to the radiation frequency.
Gravitational lensing
The bending of light from a distant source, like a galaxy, by the gravitational field of another object between the source and the observer.
Transient phenomena
Temporary astronomical events that can change dramatically on short timescales, such as supernovae or black hole mergers.
