Astronomers Find New Evidence in the Hunt for Alien Life on Mars and Venus

by

As a lifelong space enthusiast with a soft spot for sci-fi shows like “The Ark,” I can’t help but feel a thrill of excitement whenever I hear about new discoveries in our quest to uncover alien life. Growing up, I spent countless hours poring over books and articles on Mars and Venus, dreaming of the day we would find signs of extraterrestrial existence.

In the first season of SYFY’s series The Ark (currently streaming on Peacock), an exploration team encounters trouble in space, leaving their spaceship crippled and adrift between stars. They unite to survive the initial crisis and, if possible, reach their destination at Proxima Centauri b. In the second season (new episodes release every Wednesday), events take a peculiar, temporary twist.

In the fresh installment of Season 2 titled “Anomaly”, the team unexpectedly stumbles upon a distorted warp pocket where conventional physics rules no longer hold. Within this strange realm, they cross paths with an enigmatic electric entity that wreaks havoc on their vessel. This leaves both the crew and viewers pondering bizarre extraterrestrial actions within a setting unlike any we’re accustomed to, as we try to discern whether what we witness is living or not.

Essentially, what researchers in the real world are doing when studying other planets within our solar system is similar to this: Since we can’t physically go there ourselves, scientists use instruments that orbit around these distant worlds or roam across their surfaces as proxies. Whenever they discover something intriguing, it falls upon the scientists to determine whether they are observing alien geology and chemistry or signs of life beyond Earth. Lately, astronomers have reported potential signs of extraterrestrial life on Mars and Venus.

Astronomers Detect Two Biosignatures in Venus’ Atmosphere

2020 marked the year when astronomers spotted phosphine in their telescopic studies of Venus. This discovery sparked much debate and anticipation regarding the possibility of life on Venus, as phosphine is typically produced by microscopic organisms thriving in low-oxygen settings here on Earth. However, subsequent efforts to corroborate these findings proved unsuccessful, turning out to be another instance of a false alien life signal.

Venus shares several similarities with Earth: it’s nearly identical in size, has a rocky terrain, and resides within the Sun’s habitable zone. However, unlike Earth, Venus experienced a catastrophic greenhouse effect in its past, causing temperatures to skyrocket to lethal levels. Despite being much farther from the Sun than Mercury (67 million miles compared to 43 million miles), Venus is astonishingly hot. The average temperature on this sibling planet reaches around 860 degrees Fahrenheit. If it weren’t such an inhospitable environment, Venus could potentially harbor life. This is why the discovery of biosignatures like phosphine generates excitement.

1. Exploring Extraterrestrial Life: Is There Evidence of Giant Alien Structures in Our Milky Way Galaxy?

Currently, a novel receiver attached to the James Clerk Maxwell Telescope located in Hawaii has allowed astronomers to verify the existence of phosphine within Venus’ atmosphere. At a future meeting of the Royal Astronomical Society scheduled for July 2024, these scientists will share that they’ve gathered over 140 times more data than earlier observations. Interestingly, it wasn’t just phosphine they detected; ammonia was also found in Venus’ atmosphere, bringing the total number of potential biological markers to two.

Researchers hypothesize that if microorganisms reside on Venus, they could potentially produce ammonia as a means to decrease acidity in their surroundings and make certain areas of the planet more habitable. This ammonia could gradually ascend through the atmosphere towards the upper cloud layers over time. However, it’s essential to bear in mind that other possible causes exist for these signals due to Venus’s harsh environmental conditions. To date, no confirmed evidence of past or present extraterrestrial life has been found on Venus or anywhere else.

NASA’s Perseverance Rover Found a Rock Which Might Harbor Alien Fossils on Mars

NASA’s Perseverance rover has recently analyzed a Mars rock that could potentially contain signs of ancient Martian life. This rock was found to resemble an arrow and was discovered along the dried-up bed of Neretva Vallis, an old river channel that once led into Jezero Crater.

As a seasoned Mars researcher with years of exploration under my belt, I find myself intrigued by a particular rock formation that we’ve affectionately dubbed “Chevaya Falls.” With its organic compounds, water-related signs, and surface indications of chemical reactions, Chevaya Falls presents an exciting opportunity for us to explore the potential habitability of Mars.

On July 21, 2024, during its 22nd rock core sampling operation, Perseverance encountered a rock approximately 3.2 feet wide at its maximum diameter. This rock featured long white calcium sulfate streaks, interspersed with reddish bands of hematite – one of the minerals that gives Mars its distinctive red hue. Upon closer inspection, Perseverance detected numerous peculiar, white splotches encircled by black, reminiscent of leopard spots. The Onboard Planetary Instrument for X-ray Lithochemistry (PIXL), located on Perseverance, verified the presence of iron and phosphate in these rings.

If Martian life ever existed, such as fossils or microbial remnants, this type of rock could potentially preserve that information. However, the journey from a potential detection to conclusive proof is a long one, and we’re just starting our investigations at Chevaya Falls. So far, Perseverance has done everything it can do here. Further understanding of this rock and confirming if Martian life ever existed might necessitate bringing the samples back to Earth during NASA’s proposed but currently uncertain Mars Sample Return mission.

Similar to the enigmatic energy source discovered in Season 2 of “The Ark”, it remains uncertain whether the anomalies observed on Mars and Venus are indeed evidence of extraterrestrial existence, or simply unusual natural occurrences disguised in unexpected forms.
