Youngest Exoplanet Elias 2-24b Discovered by Chilean Scientists 2026

Astronomers from Diego Portales University in Chile have discovered Elias 2-24b, the youngest exoplanet ever detected. At less than one million years old, this infant gas giant is still surrounded by its natal disk of dust and gas, meaning its formation process is not yet complete.

The finding, published in a recent study, challenges current models of planet formation and suggests that gas giants can assemble much faster than previously thought.

What Makes Elias 2-24b So Young?

Elias 2-24b is a gas giant planet located in the Elias 2-24 star system. Its age is estimated at under one million years, which is incredibly young on cosmic scales. For comparison, Earth is about 4.5 billion years old.

The planet is still embedded in its protoplanetary disk—the swirling disk of gas and dust that surrounds young stars and provides the material for planet formation. This disk is a clear sign that the planet is still in the process of forming.

“It's like a baby that already has a beard and a deep voice,” said the researchers, illustrating how surprising it is to find such a massive planet at such a young age.

Why This Discovery Matters

Until now, the record for the youngest exoplanet was held by four planets each around 5 million years old. These were already puzzling because they are all gas giants like Jupiter, and current models suggest that gas giants take about 5 million years to form.

Finding a gas giant at just 1 million years old implies that planet formation can occur much more rapidly than models predict. It also suggests that the processes involved may be more common than previously thought.

This discovery forces scientists to reconsider the timeline of planet formation and the mechanisms that allow gas giants to assemble so quickly.

How Planets Form: The Basics

Stars and planets form from giant clouds of gas and dust in space. When a cloud collapses under its own gravity, it forms a star at the center, surrounded by a rotating disk of material.

Over time, dust particles in the disk stick together to form larger and larger bodies, eventually creating planets. Gas giants like Jupiter are thought to form by accumulating a solid core and then pulling in a thick envelope of gas from the disk. Context on how this played out before sits in Youngest Exoplanet Elias 2-24b Discovered by Chilean Scientists.

This process is believed to take several million years, which is why the discovery of a 1-million-year-old gas giant is so surprising. The background to this story is set out in Science: latest articles. A related thread runs through Moon City Dream Dashed: Water Shortage Limits Lunar Colony Size.

Key Takeaways

• Elias 2-24b is the youngest exoplanet ever discovered, at less than 1 million years old.
• It is a gas giant still surrounded by its natal disk, indicating ongoing formation.
• The discovery challenges current models that predict gas giants take about 5 million years to form.
• It suggests that planet formation can occur much faster than previously thought.
• This finding may lead to a reevaluation of how and when planets form.

What's Next for Researchers?

The team plans to continue studying Elias 2-24b and its disk to better understand the formation process. Future observations with more powerful telescopes may reveal similar young planets, helping to refine models of planet formation.

This discovery is a reminder that the universe is full of surprises and that our understanding of planet formation is still evolving.
