In 1967, Jocelyn Burnell, a postgraduate student at Cambridge University, detected a pulsating radio signal from deep space with a radio telescope.
The signal had a precise interval of 1.33 seconds, initially thought to be man-made interference but later confirmed to be from deep space.
The signal was named LGM-1, sparking debates on whether it was a natural occurrence or a transmission from extraterrestrial life.
Pulsating signals like these are now known to be emitted by rapidly rotating neutron stars called pulsars, akin to lighthouse beams.
Earth has been unintentionally broadcasting radio signals into space for decades, potentially alerting aliens within 100 lightyears of our presence.
The Square Kilometer Array in South Africa and Australia could detect radio signals from earthlike civilizations hundreds of lightyears away.
Arecibo Observatory sent an interstellar message in 1974, taking less than 3 minutes to transmit, with no confirmed detection of a reply.
Biosignatures, like oxygen-rich atmospheres, and technosignatures, such as artificial satellites, could indicate extraterrestrial life or technology.
The Fermi Paradox questions the lack of evidence for extraterrestrial life despite the vastness of the universe.
'Oumuamua, an extrasolar object passing through the Solar System in 2017, raised speculation as a potential interstellar probe due to its unusual characteristics.

The search for extraterrestrial intelligence is vast and uncertain, with billions of earthlike planets raising questions about the potential for life beyond Earth, including the unknown factors of abiogenesis and the probability of cosmic solitude. Despite our limited understanding, the vastness of space offers numerous unexplored opportunities for detecting signs of life, suggesting that the universe may not be as silent as we perceive.
