While you're here, how about this:

I don't belong here - The author of "Convenience Store Woman" returns | Books & arts | The

Earthlings. By Sayaka Murata. Translated by Ginny Tapley Takemori. Grove Press; 240 pages; $25. Granta; £12.99.

T WO YEARS ago Sayaka Murata won international acclaim after the English-language publication of "Convenience Store Woman", in which a shopworker struggles to escape society's pressures. For 18 years before Ms Murata wrote that book, she had herself worked part-time in a convenience store in Tokyo. "Earthlings", her second novel to be translated into English by Ginny Tapley Takemori, is another offbeat tale about outsiders in Japan.

Extraterrestrial diamonds form when planets collide, study of meteorites' insides finds-

Scientists from Goethe University have found the largest extraterrestrial diamonds to be ever discovered inside meteorites. The diamonds are a few tenths of a millimetre in size. According to a statement by the Goethe University, the team of international researchers has been able to prove that the diamonds formed in the early period of the solar system when minor planets collided together or with larger asteroids.

According to study authors, diamonds on the scale of over 0.1 and more millimetres could not have had formed when the meteoroids hit the Earth, since such impact with such vast energies would make the meteoroids evaporate completely. And so, it was earlier assumed that these larger diamonds must have been formed by continuous pressure in the interior of planetary precursors the size of Mars or Mercury.

The wow! signal: an alien missed connection? | Astronomy.com

Late in the summer of 1977, Jerry Ehman sat down to review the latest batch of computer printouts detailing data collected by the Big Ear Radio Observatory, where he was volunteering as an astronomer. The observatory was controlled remotely, and it could collect several days worth of data before the computer ran out of storage space. At that point, a technician would show up, reset things, and start the next observing run focusing on a new patch of sky.

Over the years, many other astronomers have followed-up on the Wow! Signal, either trying to explain it away or relocate it. But to astronomers like Shostak, the signal is really just one of many similar detections made over the years.

This may worth something:

Searching for habitable exoplanets? Look for phosphorus | Space | EarthSky

The new peer-reviewed paper was published September 11, 2020, in The Astrophysical Journal Letters .

Natalie Hinkel , a planetary astrophysicist and lead author of the new study, said in a statement :

Hinkel has developed techniques to help find out which stars have exoplanets (which is by far most of them), and says that upcoming studies should focus on looking for phosphorus specifically.

Hinkel decided to use the phosphorus abundance ratios in marine plankton and the Earth’s crust, as well as the bulk silicate mineral amounts of Earth and Mars as a base to compare with the carbon, nitrogen, silicon and phosphorus abundance ratios of nearby stars. She used the Hypatia Catalog , a publicly available stellar database that she had also developed. You can search through the database yourself to explore stellar abundance data for 9,434 stars.

Curious Kids: could our entire reality be part of a simulation created by some other beings?

Is it possible the whole observable universe is just a thing kept in a container, in a room where there are some other extraterrestrial beings much bigger than us? Kanishk, Year 9

* * *

Let's assume these extraterrestrial beings have a computer on which our universe is being "simulated". Simulated worlds are pretend worlds – a bit like the worlds on Minecraft or Fortnite, which are both simulations created by us.

If we think about it like this, it also helps to suppose these "beings" are similar to us. They'd have to at least understand us to be able to simulate us.

Why Astronomers Want to Build a SETI Observatory on the Moon | Science | Smithsonian

This article was originally published on Supercluster , a website dedicated to telling humanity's greatest outer space stories.

On Monday, a group of researchers sponsored by Breakthrough Listen, the world’s largest program, submitted a paper to National Academy of Sciences’ Planetary Science and Astrobiology Decadal Survey that makes the case for establishing a SETI radio observatory on the farside of the moon.

Our planet has become so “loud” in the part of the radio spectrum observed by SETI that it threatens to drown out any signal sent from an intelligent civilization. Not only would a lunar radio telescope not have to deal with terrestrial radio interference, it could also significantly increase our chances of hearing from ET by opening up parts of the radio spectrum that are blocked by Earth's atmosphere.

Drive-In Fans, Alfresco Films Are Heading to Hollywood – NBC Los Angeles

It might be tempting to say just that, given that drive-in theaters are associated with the cars that visit them, and the inclusion of "street" touches upon that fact.

Hollywood-made movies have long been shipped out to drive-in theaters across the country for decades, in canned reels, while fictional drive-in theaters have been portrayed in several flicks, from "Twister" to "Grease."

But as far as an actual drive-in being physically located in Hollywood? That's far rarer to find on this particular two-way street.
