Two Light Planets Found Around a Star
在一顆恆星周圍發現兩顆輕質行星
Introduction
Scientists found two very light planets. They call these planets 'super-puffs'. They move around a star called TOI-791.
科學家發現了兩顆非常輕的行星，他們將這些行星稱為「超級蓬鬆行星」（super-puffs）。這些行星圍繞著一顆名為 TOI-791 的恆星運行。
Main Body
A space telescope called TESS found these planets. The star is very far from Earth. The two planets are big in size, but they have very little weight. They are much lighter than the planet Jupiter.
一台名為 TESS 的太空望遠鏡發現了這些行星。該恆星距離地球非常遙遠。這兩顆行星體積龐大，但重量極輕，比木星輕得多。
These planets are very rare. Scientists know many planets, but only a few are 'super-puffs'. It is very unusual to find two of them together.
這些行星非常罕見。科學家雖然已知許多行星，但只有少數是「超級蓬鬆行星」。能同時發現兩顆這樣的行星是非常不尋常的。
Many universities worked together on this study. Now, scientists want to use a bigger telescope. They want to see what gases are in the air of these planets.
許多大學共同參與了這項研究。現在，科學家希望使用更大的望遠鏡，以觀察這些行星的大氣層中包含哪些氣體。
Conclusion
These planets help scientists understand how planets start and change.
這些行星有助於科學家了解行星是如何形成與演變的。
Vocabulary Learning
☁️ The "Light vs. Heavy" Concept
In this text, we see a special way to describe things that don't weigh much.
The Key Pattern:
Light opposite of Heavy
How it appears in the text:
- "Two light planets"
- "Very little weight"
- "Much lighter than..."
Quick Guide for A2 Learners: When you want to say something is not heavy, you can use these three levels:
- Simple: It is light.
- Stronger: It is very light.
- Comparing: It is lighter than (something else).
Vocabulary Spotlight:
- Rare Not many exist. (Example: "Super-puffs are rare.")
- Unusual Strange / Not normal. (Example: "It is unusual to find two.")
