Researchers have found a way to get close-up images of nearby #stars and #exoplanets within 25 years. These new probes would be tiny disks with optical sensors, accelerated into space by lasers, travelling at 0.2 times the speed of light. spectrum.ieee.org/high-speed-i...

30 ans d'exoplanètes : il y a des beaux mondes !

« Environ 6.000 exoplanètes sont aujourd’hui recensées. L’étude de leurs caractéristiques a permis de mettre en évidence certaines tendances, appuyant notamment le fait que le système solaire constitue une vraie rareté de l’univers. Quelles sont nos connaissances de la démographie planétaire ? »

An exoplanet, or extrasolar planet, is a world outside our solar system that usually orbits another star in our galaxy. They’re everywhere—but why study them? To explore their weirdness, variety, and the fascinating clues they offer about how planets form and evolve. Watch: youtu.be/0ZOhJe_7GrE

: Over 6,000 exoplanets have been confirmed in our galaxy so far, showing incredible variety—some similar to planets in our solar system, others vastly different. Among them are “super-Earths,” mysterious worlds larger than ours and possibly rocky.

A circular chart shows the types of over 5,000 confirmed exoplanets—but the number 5 is overlaid with a 6, reflecting that the total discoveries have surpassed 6,000 as of October 2025. The chart is divided into four groups: 35% Neptune-like, 31% super-Earth, 30% gas giant, and 4% terrestrial. Each section includes brief descriptions, and illustrations of the planet types appear alongside the percentages.

Thirty years ago, astronomers announced that they had spotted the first known #planet orbiting a Sun-like #star.

The Nobel-winning discovery was the culmination of centuries of dreaming, and decades of searching, for worlds beyond the Solar System.

Astronomers have since found more than 6 000 #exoplanets, plus hints of thousands more and the exoplanetary zoo hosts a diversity of beasts.

At the top of many recommendation lists are the two small planets that orbit Proxima Centauri, which is the closest star to the Sun — just 1.3 parsecs away in the constellation Centaurus.

"There are Jupiter-size planets that orbit closer to their parent star than Mercury orbits the Sun; planets that orbit two stars, no stars, and dead stars; planets covered in lava; some with the density of Styrofoam; and others with clouds made of gemstones." #space #science #exoplanets #nasa #astrophysics
