THE ZOOLOGIST'S GUIDE TO THE GALAXY
What Animals on Earth Reveal About Aliens — and Ourselves
By Arik Kershenbaum
The search field is incomprehensibly large: Astronomers estimate that there are more than 100 billion planets in the Milky Way alone — plus exponentially more in the rest of the universe.

The book avoids the fantasy game of proposing any specific vision of what aliens might look like — thus no Wookiees, E.T.s or little green Martians — and focuses on how they might behave . Kershenbaum predicts that some aliens will exhibit social cooperation, technology and language ("Teatime with our alien neighbors may be possible after all," he writes). He even posits that aliens will share the quality we hold most dear: intelligence.
Many things are taking place:

There are many ways of being alone. You can be alone in a room, a house, even a crowd. You can be really alone in a wilderness, or really, really alone in the universe.It's that last, existential and cosmic loneliness that astronomers and specialists in astrobiology have in mind when they ask "Are we alone?"
In 2017 astronomers were perplexed by an object first spotted by the telescope on Mount Haleakala, Hawaii. It had many traits that appeared to distinguish it from other extragalactic objects that occasionally enter our planetary neighborhood: unusual shape, rotation and speed. It was dubbed "Oumuamua" the Hawaiian word for "scout," and although most scientists doubt that it was a scout from another civilization, at least one highly regarded astronomer thinks it was.
... Messi saluted by Vidal and Xavi after matching Barcelona record
Lionel Messi was hailed as "the magical one" after he matched Xavi's appearances record for Barcelona and marked the achievement with a double strike against Huesca.
The Argentine great played his 767th game for Barca on Monday and will set an outright record if he faces Real Sociedad on Sunday.
Former Barcelona team-mate Arturo Vidal wrote on Instagram: "One more record brother @leomessi. You are the master of football. You are the best, the extraterrestrial, the only one, the magical one."
Newly discovered material may ease wear and tear on extraterrestrial vehicles

Newswise — As NASA’s Mars Perseverance Rover continues to explore the surface of Mars, scientists on Earth have developed a new nanoscale metal carbide that could act as a “superlubricant” to reduce wear and tear on future rovers.
Researchers in Missouri S&T’s chemistry department and Argonne National Laboratory’s Center for Nanoscale Materials, working with a class of two-dimensional nanomaterials known as MXenes, have discovered that the materials work well to reduce friction. The materials also should perform better than conventional oil-based lubricants in extreme environments, says Dr. Vadym Mochalin, associate professor of chemistry at Missouri S&T, who is leading the research.

No cigar: Interstellar object is cookie-shaped planet shard – KVEO-TV
Arizona State University astronomers reported this week that the strange 148-foot (45-meter) object that appears to be made of frozen nitrogen, just like the surface of Pluto and Neptune’s largest moon Triton.
The study’s authors, Alan Jackson and Steven Desch, think an impact knocked a chunk off an icy nitrogen-covered planet 500 million years ago and sent the piece tumbling out of its own star system, toward ours. The reddish remnant is believed to be a sliver of its original self, its outer layers evaporated by cosmic radiation and, more recently, the sun.

An "identified" flying object will soon grace the skies of Mars. Weighing in at a mere 4 pounds, Ingenuity, a helicopter-like drone carried to Mars by Perseverance, is scheduled to fly around Mars to photograph the Martian landscape and add another dimension to planetary exploration.

Like SETI Institute senior research scientist Janice Bishop, scientists are looking for answers to what causes a landslide-like phenomenon on Mars. We don't have actual soil samples from Mars to study yet.
