Seltener Nachweis zweier Protoplaneten

Zwei Protoplaneten im jungen Sternsystem WISPIT 2 wurden nachgewiesen, was einen seltenen Einblick in die Planetenentstehung bietet. Mit dem GRAVITY-Instrument am VLT Interferometer gelang der Nachweis des neuen Protoplaneten WISPIT 2c, der Kohlenmonoxid in seiner Atmosphäre aufweist. Dies unterstützt die Erkenntnis, dass Planetensysteme parallel entstehen.

How plants could betray themselves across the galaxy

Here's a thought experiment. Imagine looking at Earth from a distant star system, armed with a powerful telescope capable of capturing its reflected light. Could you tell the planet was alive? The answer, remarkably, might be yes and the clue would come from the color of the plants.

🪐🔭 Proxima b is the closest Earth-like #planet to our #solarsystem and sits in the habitable zone where liquid water could potentially exist.

Future missions like Breakthrough Starshot aim to send tiny probes to study this neighboring #exoplanet in the coming decades.

Exomoons Could Be Habitable for Billions of Years, Provided they have Hydrogen Atmospheres https://www.universetoday.com/articles/exomoons-could-be-habitable-for-billions-of-years-provided-they-have-hydrogen-atmospheres 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science #SolarSystem #Astrobiology

Exomoons Could Be Habitable for Billions of Years, Provided they have Hydrogen Atmospheres

Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck Institute for Extraterrestrial Physics (MPE) has shown that moons around free-floating planets can keep their water oceans liquid for up to 4.3 billion years by virtue of dense hydrogen atmospheres and tidal heating—that is to say, for almost as long as Earth has existed and sufficient time for complex life to develop.

“Lost somewhere on TRAPPIST-1f with a ship made of regolith”

34th in my “Exoplanet” series which explores facets of planets identified outside the solar system.

TRAPPIST-1f is a rocky, Earth-sized exoplanet in the habitable zone around the ultracool dwarf star TRAPPIST-1, 40.7 light-years from Earth, in the constellation of Aquarius.

Mars-Like Worlds Near M-Dwarfs May Lose Air in Millions of Years https://www.universetoday.com/articles/mars-like-worlds-near-m-dwarfs-may-lose-air-in-millions-of-years 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science #SolarSystem #Astrobiology

Mars-Like Worlds Near M-Dwarfs May Lose Air in Millions of Years

The criteria for finding an Earth-like planet unofficially comes down to two things: water and the habitable zone. But a phenomenon known as atmospheric escape often “escapes” the minds of many astronomy fans, and it turns out that atmospheric escape is one of the key characteristics for finding an Earth-like world. Although extensive research has been conducted on how the planet Mars might have lost its atmosphere, and potentially the ability to sustain life, how would the atmosphere enveloping a Mars-like exoplanet respond to stars different from our own?

Direct confirmation of two baby planets forming around a young, sun-like star https://phys.org/news/2026-03-baby-planets-young-sun-star.html 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science #SolarSystem #Astrobiology

Direct confirmation of two baby planets forming around a young, sun-like star

As the number of exoplanet detections has breached 6,000 and continues to grow, scientists are finding a wide variety of different solar system architectures. Critical to understanding how these architectures take shape is finding young planets forming around very young stars. In 2025, a team of astronomers announced the discovery of a planet about five times more massive than Jupiter around a star that's very much a younger version of our sun.
