Can aliens detect humans by signal leakages from Earth?

Published

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.

Users of WhatsApp will soon be able to lock chats on connected devices.

Additionally, linked devices will now have access to the conversation lock feature. Users of WhatsApp will also soon have the option to tag their contacts in status updates.

Notably, WhatsApp users can link their devices to log in to the same account on different devices. However, several functions, such as conversation locks and status updates, are not accessible on the secondary devices.

Even if they are locked on the main conversations, anybody can still access your private chats on a connected device. WhatsApp is currently working on adding Chat Lock capability to connected devices in order to address this.

The chat lock feature on WhatsApp will soon be available on connected devices.

Prior to this, it was claimed that WhatsApp, which is owned by Meta, was developing new personalisation options for an iOS beta.

According to WABetaInfo, an update tracker portal for the instant messaging network, WhatsApp for iOS users will soon get the option to modify both the conversation bubble’s colour and the app’s primary colour scheme.

A feature that let beta testers choose the primary colour scheme of the WhatsApp iOS app from a selection of five colours was first tested back in January.

The instant messaging app is testing a feature that lets users change the colour of chat bubbles within conversations, though, in a new beta edition.

Moon train operations are planned by NASA.

The goal is to construct the first lunar train system, which will enable safe, independent, and effective cargo transportation on the moon, according to robotics specialist Ethan Schaler of NASA’s Jet Propulsion Laboratory in Pasadena, California.

He went on, “The day-to-day functioning of a sustainable lunar base in the 2030s will depend heavily on a robust, long-lasting robotic transport system.”

The Flexible Levitation on a Track, or FLOAT, is the name of the proposed lunar rail system. According to NASA, the establishment of a railway system on the moon is “critical to the daily operations.”

According to the space agency, the primary objective of FLOAT is to offer transportation services in regions of the moon where astronauts are engaged in activities. To do this, cargoes of lunar soil and other materials will need to be transported to various regions of the moon.

Each robot will be able to transport cargo of various sizes and shapes at a pace of roughly 1 mph (1.61 km/h), according to Dr. Schaler.

Notably, NASA also declared new initiatives last month to create and test new vehicle models intended for moon exploration.

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.
