NASA’s planet-hunting telescope has found 10 new planets outside our solar system that are likely the right size and temperature to potentially have life on them.
After four years of searching, the Kepler telescope has detected a total of 49 planets in the Goldilocks zone. And it only looked in a tiny part of the galaxy, one quarter of one percent of a galaxy that holds about 200 billion stars.
Seven of the 10 newfound Earth-size planets circle stars that are just like ours. That means the planets may have some of the most basic requirements that life needs, upping the chances for life.

“Are we alone? Maybe Kepler today has told us indirectly, although we need confirmation, that we are probably not alone,’’ Kepler scientist Mario Perez said in a news conference on June 19.

美國太空總署近日透過專門搜索新星球的克卜勒太空望遠鏡發現了十顆類似地球的系外行星,不僅大小與溫度都接近地球,還可能有生物存在。

經過四年的搜尋,克卜勒太空望遠鏡在宜居帶總共發現四十九顆行星。整個銀河系估計約有兩千億顆星球,而目前美國太空總署以克卜勒太空望遠鏡調查過的區域只有其中的百分之零點二五。
在最新發現的十顆類地行星中,有七顆繞著恆星運行。這表示這些行星可能具備能孕育生命的基本條件,可能有生物存在。
參與克卜勒任務的科學家馬力歐·佩瑞斯在上個月十九日的記者會上說:「宇宙中還有其他的生命嗎?雖然現在還無法證實,但或許克卜勒的新發現已經間接告訴我們,在地球之外是有其他生物的。」

South Korea’s famous kimchi is falling victim to climate change, with scientists, farmers and manufacturers saying the quality and quantity of the napa cabbage that is pickled to make the ubiquitous dish is suffering due to rising temperatures. Napa cabbage thrives in cooler climates, and is usually planted in mountainous regions where temperatures during the key growing summer season once rarely rose above 25 degrees Celsius. Studies show that warmer weather brought about by climate change is now threatening these crops, so much so that South Korea might not be able to grow napa cabbage one day due to the intensifying heat. “We
It’s widely recognized that there are far more right-handed people than left-handed people in the world. Being right-handed simply means preferring to use one’s right hand for tasks that involve only one hand, such as writing and eating. But have you ever wondered about the possible reasons behind the global dominance of the right hand over the left? As with many complex biological questions, multiple factors appear to be at play. First, one reason seems to be genetics. __1__ Therefore, the global dominance of right-handedness is something that has been passed down through many generations of humans. Next,
A: What’s even more horrible is that the five suspects who purposely supplied ketamine to actor Matthew Perry were all his “friends.” B: Who exactly are the five suspects? A: They include Matthew’s two doctors, a broker, a drug dealer, and even his live-in assistant. B: Those scumbags should go to jail. A: Yeah, one of the doctors may be sentenced to up to 120 years in prison. A: 更可怕的是,提供男星馬修派瑞「K他命」的5人全是他的「朋友」。 B: 嫌犯是誰啊? A: 其中包括他的2位醫生、1位仲介、1位毒販、甚至他的同居助理! B: 那些人渣真該去坐牢。 A: 對啊,其中1位醫生可能面臨120年徒刑。 (By Eddy Chang, Taipei Times/台北時報張聖恩)
Continued from yesterday(延續自昨日) https://www.taipeitimes.com/News/lang Finally, cultural influence also plays a role in which hand people prefer. Historically, items that require physical manipulation have been designed for right-handed use. For example, tools like scissors and musical instruments are often constructed with right-handers in mind, making it difficult for left-handers to use them. __4__ While these factors offer some explanation, they remain speculative. The precise reasons for the global prevalence of right-handed people continue to be debated. Nevertheless, left-handedness will remain a phenomenon of great curiosity among scientists and researchers for many years to come. 最後,文化影響也在人們偏好哪一隻手上扮演一角。歷史上,需要用到肢體操作的物品都被設計來供右手使用。舉例來說,像是剪刀、樂器等工具常常就是考慮到右撇子而打造的,造成左撇子難以使用這些工具。因此,許多天生就是左撇子的人可能就必須透過學習使用右手來適應。 雖然這些因素都提供了一些解釋,但它們仍是推測而已。全球右撇子如此普及,確切的原因仍持續被爭論著。不過,在未來的許多年裡,左撇子依然會是科學家和研究人員相當好奇的一個現象。 What Did You Learn?
