Hubble Telescope Looks at Stars

哈伯望遠鏡觀測星辰


Introduction

NASA has a big telescope called Hubble. It took photos of two places in space to learn how stars grow.

NASA 有一座巨大的望遠鏡稱為哈伯。它拍攝了太空中兩個地方的照片,以研究恆星如何成長。

Main Body

Hubble looked at a place called LH 95. It found 2,500 young stars. These stars are still growing. They grow for a long time. Some stars there are older and some are younger.

哈伯觀測了一個名為 LH 95 的地方。它發現了 2,500 顆年輕的恆星。這些恆星仍在成長中,且成長時間很長。那裡有些恆星較老,有些則較年輕。

Then Hubble looked at Messier 3. This is a group with 500,000 stars. Some stars here change their light. This helps scientists find the distance to the stars.

接著哈伯觀測了 Messier 3。這是一個擁有 50 萬顆恆星的星團。這裡有些恆星的光度會改變,這有助於科學家計算恆星的距離。

Some stars in Messier 3 look young because they take gas from other stars. Scientists think two groups of stars hit each other a long time ago. This helped make our galaxy.

Messier 3 中的某些恆星看起來很年輕,是因為它們從其他恆星吸收氣體。科學家認為很久以前有兩個星團發生了碰撞,這有助於我們星系地形成。

Conclusion

These photos help us understand how stars grow and how our galaxy started.

這些照片幫助我們了解恆星如何成長,以及我們的星系是如何開始的。

🌌 The 'State' of Things

In this text, we see how to describe things that are happening right now or are true. At A2 level, we focus on Simple Present patterns.

1. The 'Is/Are' Pattern We use these to describe what something is:

  • Hubble is a big telescope.
  • These stars are still growing.

2. Action Patterns (The 'Do' words) Look at how the text describes habits or facts:

  • Hubble looks...
  • Stars change...
  • Scientists think...

3. Simple Word Swaps (Opposites) To move from A1 to A2, you need to describe differences. The article uses these pairs:

  • Older \rightarrow Younger
  • Big \rightarrow Small (implied)

Quick Tip: Notice that when the text talks about 'Hubble' (one thing), it adds an -s to the action (looks). When it talks about 'Stars' (many things), there is no -s (grow).
