What is the size and structure of the Universe?
Today we understand the Universe to be an immensely complex structure, which is home to hundreds of billions of galaxies that each contain billions of stars and planets. The tools we have today are orders of magnitude more powerful and precise than the best facilities available at the beginning of the 20th century. We can now peer into the far reaches of the observable Universe as well as look back into its origins. However, there is much that we still do not yet understand.

What is dark matter composed of? What is the true nature of dark energy? What intricate mysteries of the Universe can be uncovered by gravitational waves and other multi-messenger probes? Is there more than one Universe or do we indeed live in a Multiverse? These and many other exciting questions await to be tackled by the next generation of astronomers.

How do stars form and shine?
Stars are some of the most magnificent objects in the Universe. Research during ?the 20th century revealed what stars are made of and what makes them shine, allowing us to investigate how they evolve. By studying the stars, we have developed a better understanding of how the elements are created, but there remains much more to be discovered.

What really happens in the early stages of star formation? How do planetary systems form and what controls their architecture? How do the cores of mature stars rotate and how much do newly-formed elements mix? Where are proton-rich isotopes formed? The next century of astronomical research holds many mysteries and exciting revelations.

Is there life elsewhere in the Universe?
Unlike popular belief at the beginning of the century, we now have strong evidence that the conditions for life to arise do exist in some form beyond Earth itself. Perhaps life is hidden deep beneath the surface of Mars, in the underground oceans of some of Jupiter's and Saturn's moons, or elsewhere. Recent space missions are bringing us closer to verifying this hypothesis, opening a potentially new chapter in the history of humankind. We have also set our eyes on Mars, with prospects to send a human mission to the Red Planet in the coming decades.

Is that all? Can we expect some form of extraterrestrial contact from outside of our Solar System? Will we ever develop tools so powerful to unambiguously detect the presence of life on exoplanets? The future might surprise us in unexpected ways.
