Blasting out Earth’s location with the hope of reaching aliens is a controversial idea – two teams of scientists are doing it anyway
https://theconversation.com/blasting-out...way-182036

EXCERPTS: . . . While SETI has long been a part of mainstream science, METI, or messaging extraterrestrial intelligence, has been less common.

I’m a professor of astronomy who has written extensively about the search for life in the universe. I also serve on the advisory council for a nonprofit research organization that’s designing messages to send to extraterrestrial civilizations.

In the coming months, two teams of astronomers are going to send messages into space in an attempt to communicate with any intelligent aliens who may be out there listening. These efforts are like building a big bonfire in the woods and hoping someone finds you. But some people question whether it is wise to do this at all.

[...] The prospect of alien contact is ripe with ethical questions, and METI is no exception.

The first is: Who speaks for Earth? In the absence of any international consultation with the public, decisions about what message to send and where to send it are in the hands of a small group of interested scientists.

But there is also a much deeper question. If you are lost in the woods, getting found is obviously a good thing. When it comes to whether humanity should be broadcasting a message to aliens, the answer is much less clear-cut.

Before he died, iconic physicist Stephen Hawking was outspoken about the danger of contacting aliens with superior technology. He argued that they could be malign and if given Earth’s location, might destroy humanity. Others see no extra risk, since a truly advanced civilization would already know of our existence. And there is interest. Russian-Israeli billionaire Yuri Milner has offered $1 million for the best design of a new message and an effective way to transmit it.

To date, no international regulations govern METI, so the experiments will continue, despite concerns... (MORE - missing details)


Scientists have found all the bases of DNA in meteorites. Now, there’re good chances of life on exoplanets

INTRO: Scientists have confirmed for the first time that meteorites and space rocks that have recently fallen to Earth contain all 5 bases that store information in DNA and RNA. And among these, scientists also found 30 nitrogen heterocyclic molecules in the meteorites.

The 5 bases are in order: adenine, guanine, cytosine, thymine, and uracil. They combine with sugars and phosphates, making up the entire code of life on Earth. This discovery makes us think a little about how life came to be on Earth.

Researchers claim that the new discovery is in addition to the many pieces of evidence that show that all this code of life that is now, breathes, and thinks on Earth, came from space. However, there is also the possibility that only certain "ingredients" came from space, and that the creation of codes that are now in our DNA began on Earth.

But something clearly comes from space and is not the first discovery to show that meteorites may have brought the necessary elements from space to create life on Earth, but it is the most complex discovered to date... (MORE - missing details)
