Do you know anything about the Moon? How much do you know about it?
The Moon is an unfriendly place. There is no air or water. There are only lots of dust and mountains around on it.
But from the Moon, you can see our beautiful Earth. It is shining more brightly than the other stars in the dark.
| A．So there are no animals or plants there. |
| B．The Moon is also a very quiet world. |
| C．Do you want to go there? |
| D．You can take some photos with your camera. |
| E．When the Sun shines in the day, the temperature is very high. |

【推荐1】European researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the future. Researchers from the European Space Agency（ESA）carried out the experiments and reported their results in a study.
The team says ESA’s experimental “plant” was able to successfully produce oxygen from simulated moon dust. The dust is part of a material known as regolith, which holds about 45 percent oxygen. However, the oxygen’s form is very strange, so it is hard to produce.
ESA’s long -term goal is to design an oxygen -producing “pilot plant” to work fulltime on the moon. Beth Lomax of the University of Glasgow was a lead researcher on the project. “Being able to get oxygen from resources found on the moon would certainly be hugely useful for future lunar settlers,” she said.
The researchers reported that the process also produced some usable metal materials. ESA researcher Alexandre said the finding that a number of metals are left behind was an important discovery.
ESA and the U. S. space agency NASA are both working on plans to return human beings to the moon. NASA has set a goal for 2024, with the aim to keep humans on the moon for long periods.

According to a study published in Nature on June 23, astronomers(天文学家) have found that 1,715 stars have had a direct view of Earth since humans were here.
In order to do this, scientists used a method that looked for life on other planets. But instead, they changed the method so it could try to decide what places could see us.
The team looked at 331,312 stars within 326 light-years of Earth. Out of all those stars, only 1,715 of them could see Earth within the last 5,000 years, with an extra 319 stars that will be able to see us in the next 5,000 years.
“When I look up at the sky, it looks a little bit friendlier because it’s like, maybe somebody is waving,” said Lisa Kaltenegger, director of the Carl Sagan Institute at Cornell University, US, and the study’s lead writer.
If a planet circling around one of those 1,715 stars is home to advanced life, they could easily see that there is life here because of the oxygen on Earth. If that didn’t give it away, then the radio waves we have sent out into space would also be an indicator. In fact, human-made radio waves have already travelled through 75 of the closest stars on Kaltenegger’s list.
Why haven’t we heard from anyone yet, then?
It takes a long time for messages to travel between star systems. By the time a message could be received, that advanced life would probably not exist anymore.
Alan Boss, a scientist at the Carnegie Institution for Science in the US who wasn’t part of the study, wrote in an email that this long time would limit the chances for different life to exchange “emails and TikTok videos”.
“So we should not expect aliens to show up anytime soon,” Boss said.
