Organic Molecules Have Been Confirmed in The Jezero Crater on Mars

Posted by in category: alien life

It hasn’t even been on Mars a full year, and NASA’s Perseverance rover is making excellent surprise discoveries.

Amid a number of findings announced this week at the American Geophysical Union Fall Meeting, scientists have revealed that the Jezero Crater formed from molten volcanic magma – and that organic molecules have been discovered in rocks and dust on the crater floor.

$10 Billion Webb Space Telescope Launch Delayed — Here’s What We Know

Posted by in categories: alien life, chemistry

The James Webb Space Telescope is the largest, most powerful, and most technologically challenging space telescope ever built.

The Webb Telescope is so large; it must be folded like origami to fit inside its rocket fairing for the ride into space. Once in space, unfolding and readying Webb for science is a complex process that will take about six months.

Webb is designed to see the most distant galaxies in the Universe and study how galaxies evolved over cosmic time. Webb will study planets orbiting other stars looking for the chemical signatures of the building blocks of life. Webb will also study planets within our own solar system.

We’ve Found A Unique Giant ‘Tatooine’ Planet That Orbits Two Stars Say Scientists

Posted by in category: alien life

Astronomers just found something unique in the Milky Way–a giant exoplanet in a 200-days orbit around two stars.

In a find that remind us of that binary sunset in the original Star Wars movie, the Tatooine-like “TIC 172900988b” is a Jupiter-sized planet.

Known as a “circumbinary” planet, TIC 172900988b’s existence has been revealed in a paper published in the Astronomical Journal by a team led by Veselin B. Kostov of the SETI Institute.

We Asked a NASA Expert: How Did Perseverance Mars Rover Pick Its Landing Spot? [Video]

Mars rover pick its exact landing spot? Believe it or not, the Mars rover decided precisely where to land just moments before it touched down. It’s thanks to the work of engineers like NASA’s Jet Propulsion Laboratory’s Swati Mohan and new technology called Terrain Relative Navigation.

When NASA decides to send a rover to Mars, a whole group of experts gets together to figure out where it needs to go for the best science for that mission. Perseverance’s mission was to find the signs of past life on Mars. So, all the experts got together and picked Jezero crater.

The Science of Aliens, Part 7: How Would WE React to Discovering Alien Life

Posted by in categories: alien life, science

What the discovery of alien life means for our human society. For more info, see.


Ready or not, this discovery is likely to happen soon. In anticipation of discovering alien life, conferences have been held on what such a discovery would mean for humanity. But how would we as humans react to this discovery? That reaction would depend on how advanced the alien life is and whether it would be considered a danger to us. Let´s start with the possibility that we find microbial life on another planet. In a seminal paper published in Frontiers of Psychology, a team of scientists led by Jung Kwon from Arizona State University reported that people would react more positively than negatively to discovering alien life. They partially based their findings on how people reacted to the announcement of fossil life in the Martian meteorite ALH84001, which created excitement in the scientific community (the discovery itself, however, has remained controversial till today and it is unclear whether it is evidence for the existence of past life on Mars).

A 4 billion-year-old rock could make our search for life on Mars harder

Why men are so into space (and why that sucks for women)

Posted by in categories: alien life, Elon Musk

“THE MORE WE TRY TO FORCE EQUALITY, THE MORE WE’RE CREATING A DIVIDE.”

Amy Shira Teitel


And it was male-helmed mega-companies that spurred this surge in space travel. In July, Richard Branson launched himself into suborbital flight on a Virgin Galactic spacecraft. A week later, Jeff Bezos followed suit on a Blue Origin rocket. Elon Musk’s SpaceX launched the first all-civilian space flight in mid-September. Then, Bezos brought sci-fi to life by sending Captain Kirk himself, William Shatner, on a suborbital flight in October.

A philosopher of science explains how birds perceive time and space differently than humans

Posted by in categories: alien life, science

The human and the bird worlds overlap, particularly in cities and suburbs where we have to tolerate each other’s presence. With this in mind, a group of Spanish scientists set out earlier this year to observe whether humans’ changing behavior as a result of the pandemic had affected our feathered friends. Published in the journal Proceedings of the Royal Society B, the researchers’ findings repeatedly surprised them. For one thing, scientists expected birds to be more abundant in urban and town spaces, places that humans were suddenly scarcer in. This proved not to be the case. Yet birds did change their routines in response to humans become quieter. Notably, some species of male birds became louder and more musical, as the reduction of noise pollution allowed them to perform their calls earlier in the day.

It is strange to think that birds live among us, and yet are so alien in their everyday routines and lives. Vinciane Despret — a Belgian philosopher of science and associate professor at the University of Liège — would like to change that with her new book, “Living as a Bird” (translated by Helen Morrison). Opening with observations about a nearby warbling blackbird, Despret immerses readers into the world as it is perceived by those with wings, beaks and talons. While birds of different species will co-exist peacefully during the migratory months of winter, they ostentatiously sing once spring comes and become very aggressive with other birds. To understand both this process and birds’ mindsets more broadly, Despret approaches the subject with the vivid prose of a creative writer instead of the dry, dense verbiage of the detached scientist.

If there is a common theme throughout the book, it is that differences between species (and, for that matter, within the biological sexes in each species) are layered, intersected and rarely as simple as we might prefer to think. Using this understanding as a narrative lens, Despret’s book explores how birds transition from peacefully co-existing during the winter migration to a complex social system in which they sing aggressively, form alliances and behave territorially. Despret told Salon that there were several important lessons she learned about how a bird’s point of view will differ from a human’s. The first involves their perception of time.

The supersymmetric bottom quark and its friends

Posted by in categories: alien life, particle physics, quantum physics

When it comes to quarks, those of the third generation (the top and bottom) are certainly the most fascinating and intriguing. Metaphorically, we would classify their social life as quite secluded, as they do not mix much with their relatives of the first and second generation. However, as the proper aristocrats of the particle physics world, they enjoy privileged and intense interactions with the Higgs field; it is the intensity of this interaction that eventually determines things like the quantum stability of our Universe. Their social life may also have a dark side, as they could be involved in interactions with dark matter.

This special status of third-generation quarks makes them key players in the search for phenomena not foreseen by the Standard Model. A new result released by the ATLAS Collaboration focuses on models of new phenomena that predict an enhanced yield of collision events with bottom quarks and invisible particles. A second new ATLAS search considers the possible presence of added tau leptons. Together, these results set strong constraints on the production of partners of the b-quarks and of possible dark-matter particles.
