About 3I/ATLAS Interstellar comet

3I/ATLAS is  interstellar comet just recently discovered in July 2025, that has passed through our solar system.  The mission of 3I/ATLAS (which stands for "3-Phase Ice, Ice and Atmosphere Study") is to explore and study celestial bodies, particularly focusing on ice and atmospheric phenomena. It aims to enhance our understanding of these elements in various environments, which can provide insights into climate change, planetary formation, and the potential for life beyond Earth. Key objectives include: 1. Ice Analysis: Investigating the composition and behavior of ice on different celestial bodies. 2. Atmospheric Studies: Examining the atmospheres of various planets and moons, assessing their properties and dynamics. 3. Climate Research: Understanding the historical and current climates of these bodies, which helps in broader climate modeling. This mission is crucial for scientific advancement, potentially aiding in future explorations and habitation of other pla...

Five planets revealed after 20 years of observation

Over 4000 exoplanets have been discovered since the first one in 1995, but the vast majority of them orbit their stars with relatively short periods of revolution. Indeed, to confirm the presence of a planet, it is necessary to wait until it has made one or more revolutions around its star. This can take from a few days for the closest to the star to decades for the furthest away: Jupiter for example takes 11 years to go around the sun. Only a telescope dedicated to the search for exoplanets can carry out such measurements over such long periods of time, which is the case of the EULER telescope of the Geneva University (UNIGE), Switzerland, located at the Silla Observatory in Chile. These planets with long periods of revolution are of particular interest to astronomers because they are part of a poorly known but unavoidable population to explain the formation and evolution of planets.
