- 4. Located on a Chilean telescope, this spectroscope was one of the most prolific at detecting exoplanets over the last few years, using the radial velocity method.
- 5. This simple molecule, when available in liquid form, can be one of the most important indicators for the habitability of a planet.
- 8. First name Giordano, this Italian astronomer who lived in the XVI-th century was famous for being one of the first to speculate about the possibility of the existence of exoplanets.
- 9. These clouds of gas and interstellar dust are the nurseries of the next generation of stars.
- 11. It was orbiting around the 51-st star of this constellation that, in 1995, the first exoplanet was discovered.
- 13. One of the exoplanet detection methods with greatest success over the last few years. It is based on the measurement of light curves of stars over long periods of time.
- 15. Famous Italian astronomer and physicist, he named and popularized a paradox that questions the apparent absence of intelligent extraterrestrial lifre from our observable universe.
- 18. The existence of these waves, first predicted by Einstein, was only very recently experimentally confirmed, with a collision between two very massive cosmic objects.
- 19. The equation named after this astronomer tries to estimate the amount of alien civilizations present in our galaxy with which communication would be possible.
- 20. These holes in space represent regions where the gravitational force is so strong not even light itself can escape.

- 1. These dwarf stars are a result of the death of a star like our Sun, and they are made up of degenerate matter. They slowly cool down over a period of thousands of millions of years.
- 2. One of the more energetic cosmic phenomena. It marks the end of a star's life.
- 3. This ESA mission, sent to space in 2013, has, as one of its main objectives, the measurement of the positions of hundreds of millions of stars and, through the study of their locations in the sky, to detect exoplanets orbiting around them.
- 6. Launched in 2018, this is one of NASA's most recent space missions for the detection and study of exoplanets.
- 7. Compact stars with very stable rotation rates, they emit electromagnetic radiation at a highly precise rate. They are like the lighthouses of the Universe.
- 10. Type of star made of extremely dense nucleon soup. They can be created at the end of the life of a star more massive than our Sun.
- 12. Bursts of these rays are extremely energetic phenomena, and where for many years after their discovery a mystery to astronomers. Some thought they were caused by secret military tests, but they actually originate from distant galaxies.
- 14. This institute has as its main goal the discovery and contact with extraterrestrial intelligence.
- 16. Swiss astronomer, he discovered the first planet outside of our Solar System, and was rewarded with the Nobel prize for that discovery.
- 17. Exoplanet discovered in 2008, it was baptized in 2019 by the IAU with the name of a Lusitan leader murdered by the Romans.
