China Says It May Have Detected Signals From Alien Civilizations

Posted by in category: alien life

The narrow-band electromagnetic signals detected by Sky Eye — the world’s largest radio telescope — differ from previous ones captured and the team is further investigating them, the report said, citing Zhang Tonjie, chief scientist of an extraterrestrial civilization search team co-founded by Beijing Normal University, the National Astronomical Observatory of the Chinese Academy of Sciences and the University of California, Berkeley.

It isn’t clear why the report was apparently removed from the website of the Science and Technology Daily, the official newspaper of China’s science and technology ministry, though the news had already started trending on social network Weibo and was picked up by other media outlets, including state-run ones.

In September 2020, Sky Eye, which is located in China’s southwestern Guizhou province and has a diameter of 500 meters (1,640 feet), officially launched a search for extraterrestrial life. The team detected two sets of suspicious signals in 2020 while processing data collected in 2019, and found another suspicious signal in 2022 from observation data of exoplanet targets, Zhang said, according to the report.

There Could Be Four Hostile Civilizations in the Milky Way

Posted by in category: alien life

In 1977, the Big Ear Radio Telescope at Ohio State University picked up a strong narrowband signal from space. The signal was a continuous radio wave that was very strong in intensity and frequency and had many expected characteristics of an extraterrestrial transmission. This event would come to be known as the Wow! Signal, and it remains the strongest candidate for a message sent by an extraterrestrial civilization. Unfortunately, all attempts to pinpoint the source of the signal (or detect it again) have failed.

This led many astronomers and theorists to speculate as to the origin of the signal and what type of civilization may have sent it. In a recent series of papers, amateur astronomer and science communicator Alberto Caballero offered some fresh insights into the Wow! Signal and extraterrestrial intelligence in our cosmic neighborhood. In the first paper, he surveyed nearby Sun-like stars to identify a possible source for the signal. In the second, he estimates the prevalence of hostile extraterrestrial civilizations in the Milky Way Galaxy and the likelihood that they’ll invade us.

We’re one step closer to Europa.


Engineers completed the Clipper’s main body, which includes some of the most vital components for the 2024 mission to Jupiter’s mysterious moon.

Life on Mars: A critical tool in the search for aliens is delayed

Posted by in category: alien life

We won’t give up on the search for life on Mars.


The situation developed in the next days and weeks, leading to a series of emergency meetings. On March 17, the European Space Agency (ESA)’s council and member states decided to suspend our mission. We won’t know for sure what happens next until a study by ESA and industry partners reports back in July — but there are causes for optimism.

First Mexican-born woman travels to space with Blue Origin

Posted by in category: alien life

CNN — A rocket built by Jeff Bezos’ Blue Origin carried its fifth group of passengers to the edge of space, including the first-ever Mexican-born woman to make such a trek.

The 60-foot-tall suborbital rocket took off from Blue Origin’s facilities in West Texas at 9:26 A.M ET, launching a group of six people to more than 62 miles above the Earth’s surface — which is widely deemed to make the boundary of outer space — and giving them a few minutes of weightlessness before parachuting to landing.

Most of the passengers paid an undisclosed sum for their seats. But Katya Echazarreta, an engineer and science communicator from Guadalajara, Mexico, was selected by a nonprofit called Space for Humanity to join this mission from a group of thousands of applicants.

The Perseverance Rover of NASA captured a flying object on Mars

Posted by in categories: alien life, robotics/AI, transportation

Is this true?


The Perseverance rover has been on Mars for two weeks and has now spun its wheels and began its maiden trek over the red planet’s surface. According to new images transmitted to Earth by the one-ton robot on Friday, the voyage was a quick one.

Engineers have worked tirelessly to get the vehicle and its numerous equipment up and operating, including instruments and a robotic arm. Perseverance’s mission is to look for indications of alien life in the Jezero crater, which is located near the equator. This will take roughly 15 kilometers throughout the following Martian year (approximately two Earth years).

NASA’s Psyche Spacecraft Arrives at Kennedy Space Center

Posted by in categories: alien life, chemistry, evolution

For the past fifty years of space exploration, mass spectrometry has provided unique chemical and physical insights on the characteristics of other planetary bodies in the Solar System. A variety of mass spectrometer types, including magnetic sector, quadrupole, time-of-flight, and ion trap, have and will continue to deepen our understanding of the formation and evolution of exploration targets like the surfaces and atmospheres of planets and their moons. An important impetus for the continuing exploration of Mars, Europa, Enceladus, Titan, and Venus involves assessing the habitability of solar system bodies and, ultimately, the search for life—a monumental effort that can be advanced by mass spectrometry. Modern flight-capable mass spectrometers, in combination with various sample processing, separation, and ionization techniques enable sensitive detection of chemical biosignatures.

Planetary Mass Spectrometry for Agnostic Life Detection in the Solar System

Circa 2021


For the past fifty years of space exploration, mass spectrometry has provided unique chemical and physical insights on the characteristics of other planetary bodies in the Solar System. A variety of mass spectrometer types, including magnetic sector, quadrupole, time-of-flight, and ion trap, have and will continue to deepen our understanding of the formation and evolution of exploration targets like the surfaces and atmospheres of planets and their moons. An important impetus for the continuing exploration of Mars, Europa, Enceladus, Titan, and Venus involves assessing the habitability of solar system bodies and, ultimately, the search for life—a monumental effort that can be advanced by mass spectrometry. Modern flight-capable mass spectrometers, in combination with various sample processing, separation, and ionization techniques enable sensitive detection of chemical biosignatures. While our canonical knowledge of biosignatures is rooted in Terran-based examples, agnostic approaches in astrobiology can cast a wider net, to search for signs of life that may not be based on Terran-like biochemistry. Here, we delve into the search for extraterrestrial chemical and morphological biosignatures and examine several possible approaches to agnostic life detection using mass spectrometry. We discuss how future missions can help ensure that our search strategies are inclusive of unfamiliar life forms.

Biosignatures are the tantalizing chemical and physical imprints associated with life, and the possibility that life exists elsewhere beyond Earth drives us to search for these biosignatures on other planets and moons. The enterprise of space exploration, galvanized by the question of “Are we alone in the Universe?”, demands a stronger understanding of the diversity of biosignatures that life could express, thereby driving payload instruments on board astrobiology missions to offer broader and more advanced detection capabilities. In tandem with cutting-edge instrument platforms, research in data processing and data analysis on Earth-based (Terran) astrobiology analogs and on extraterrestrial materials also serves to increase the breadth of interpretations possible with mission data.
