Can aliens detect humans by signal leakages from Earth?

Researchers have hypothesised in their new study that aliens living on foreign planets need to be technologically more advanced than human beings to detect radio signal leakages from Earth, reported Independent.

The experts simulated the leakage of radio signals from mobile towers and predicted what extraterrestrial life would see on Earth as near as six light years away.

Aliens that may be technologically advanced may not rely on current mobile tower radio signals leakages into space to detect human life, according to the findings published in the journal MNRAS.

The study stated that unless an alien civilisation is much more advanced than humans, “they will find it difficult to detect current levels of mobile tower radio leakage from Earth.”

The researchers also suggested that the detectability of mobile systems on Earth will increase substantially as more powerful broadband systems are adopted across Earth.

The findings of the study also suggested that Earth’s mobile radio signature includes a substantial contribution from Africa, shedding light on the continent’s transition into the digital age after bypassing the landline era.

A co-author Mike Garrett from Manchester University said: “I’ve heard many colleagues suggest that the Earth has become increasingly radio-quiet in recent years — a claim that I always contested — although it’s true we have fewer powerful TV and radio transmitters today, the proliferation of mobile communication around the world is profound.”

“While each system represents relatively low radio powers individually, the integrated spectrum of billions of these devices is substantial,” Dr Garrett said.

“I believe that there’s every chance advanced civilisations are out there, and some may be capable of observing the human-made radio leakage coming from planet Earth,” said Nalini Heeralall-Issur, another author of the study.

While studying further into the matter, scientists hope to examine the signal leakage from powerful civilian and military radars, new digital broadcast systems, Wi-Fi networks, individual mobile handsets and satellites like Elon Musk’s Starlink system.

“Current estimates suggest we will have more than one hundred thousand satellites in low Earth orbit and beyond before the end of the decade,” Dr Heeralall-Issur said.

“The Earth is already anomalously bright in the radio part of the spectrum; if the trend continues, we could become readily detectable by any advanced civilization with the right technology,” she said.

Pakistan’s lunar mission (ICUBE-Q) entered orbit around the moon on Wednesday.

Pakistan’s historic lunar mission (ICUBE-Q) launched from Hainan, China, on Friday aboard China’s Chang’E6 spacecraft.

According to the IST, the satellite ICUBE-Q was planned and developed in partnership with China’s Shanghai University SJTU and Pakistan’s national space agency SUPARCO.

The ICUBE-Q orbiter is equipped with two optical cameras to image the lunar surface. ICUBE-Q has now been integrated into the Chang’e6 mission after successfully qualifying and testing it.

Chang’e6 is the sixth lunar exploration mission launched by China.

The launch event was streamed live on the IST website and social media platforms. Chang’6, China’s Lunar Mission, will land on the Moon’s far side to collect surface samples before returning to Earth for further research.

SIFC was established to improve the ease of doing business for potential investors through a “Whole of Government”Approach”—achieving optimal horizontal-vertical synergy and facilitation by the Pakistan Army—and to attract investments from friendly countries in selected sectors through an empowered organisation that serves as a “single-window” platform for facilitation.

The children will learn the newest skills in these state-of-the-art IT labs, expanding their employment prospects.

These IT laboratories will be constructed in sixteen degree colleges spread throughout various parts of Islamabad.

Students will take six-month courses in artificial intelligence (AI), game development, data science, and block chain in these IT labs.

Approximately 1,000 students will have access to courses in the first phase, which is being implemented in response to market demand.

The National Vocational and Technical Training Commission has worked with esteemed universities such as NUST, National Skills University, COMSATS, and NUML to produce these courses.

The second week of this month will mark the start of these classes. For these courses, about 3,600 students have signed up.

Pakistan launches first-ever lunar mission with iCube Qamar

China’s Chang’E6 spacecraft carried Pakistan’s first satellite mission to the moon, iCube Qamar, into orbit.

The Institute of Space Technology states that IST worked with Pakistan’s national space agency SUPARCO and China’s Shanghai University SJTU to design and develop the satellite ICUBE-Q.

The launch event was streamed live on both Chinese state television and the IST website.

Two optical cameras are carried by the ICUBE-Q orbiter to capture images of the lunar surface. ICUBE-Q has now been successfully integrated into the Chang’e6 mission after qualification and testing.

The sixth in China’s sequence of lunar exploration missions is called Chang’e6.

China’s Lunar Mission, Chang’6, will land on the Moon’s far side in order to gather surface samples and bring them back to Earth for analysis.

Pakistan would benefit from the mission since it will carry a Pakistan CubeSat Satellite, called iCube-Q, which was created by IST.

Small satellites known as “CubeSats” are typified by their uniform design and compact size. They are built in the form of a cube and are made up of modular parts that follow predetermined dimensions.

These satellites are regularly placed in orbit for a variety of uses and only weigh a few kilos.

Cubesats are primarily used to support space exploration education, technology development, and scientific research. Many different missions are carried out by these satellites, such as telecommunication, astronomy, remote sensing, Earth observation, atmospheric research, and technological demonstration.

CubeSats provide universities, research centers, and commercial organizations with the chance to engage in space missions and acquire important data for scientific advancement and innovation because of their small size and very low cost when compared to regular satellites.

They act as test beds for novel ideas and technology, opening up space to a wider spectrum of users and encouraging cooperation amongst members of the space community.
