Carbon is the backbone of life because it can build stable, complex molecules that store energy, form cells, and support metabolism.

Learn what a super Earth is, how it differs from Earth and mini-Neptunes, and why astronomers care about these common exoplanets.

Most exoplanets are found indirectly because planets are tiny, dim, and hard to separate from bright stars.

Mars preserves some of the best clues for testing how life starts, survives, and leaves detectable traces.

Learn how charged particles travel from the Sun to Earth, what shapes their path, and why the magnetosphere matters.

Super-Earths are intriguing because they blur the line between rocky planets and mini-Neptunes, opening new questions about habitability, geology, and planetary formation.

Scientists search for exoplanets to find habitable worlds, study planet formation, and understand whether life exists beyond Earth.

Solar storms happen more often than many people realize. Learn their frequency, drivers, and how to gauge the risk from space weather.

Learn what makes an exoplanet habitable, how scientists detect them, and why the search for life focuses on a narrow set of planetary conditions.
