A probe that kept going. A moon wrapped in ice. A place where stars take shape. You do not need a science degree to find something fascinating.

Launched in 1977, Voyager 1 turned a journey past the outer planets into a story about interstellar space. Follow the mission rather than a live distance counter: the route is the remarkable part.
Start with the boundary: what does leaving the heliosphere actually mean?
National Aeronautics and Space Administration (NASA) / Jet Propulsion Laboratory (JPL) · Public domain · cropped to fitAn icy moon of Saturn with a surprisingly active story. Its bright surface is only the beginning; Cassini’s observations made this small world a compelling place to ask what might lie beneath the ice.
Follow the evidence: what did Cassini observe, and what can scientists infer from it?

Look past the name: how can the same environment build structures and wear them away?

Take the next step: how are the rings different from the solid band they seem to form?

Change the scale: what separates a galaxy, a nebula and a star?
NASA · Public domain · cropped to fitWebb’s infrared observations offer a different view of the universe. Familiar subjects can reveal structures that visible-light pictures miss.
Compare observations: why does the wavelength of light change what a telescope can show?
Compare the ice on Enceladus with Saturn’s rings. Follow the Pillars of Creation from a famous picture to the gas and dust behind it. The next question is often the interesting part.
