Indian-British Scientist’s Exoplanet Discoveries Stir Hope On Alien Life

The vast cosmos has always been a source of intrigue, with the quest for life beyond Earth spanning decades. The recent revelation of potential biosignatures on the exoplanet K2-18b has sent ripples through the astronomical community. This has prompted a retrospective look at the past decade of discoveries that have revolutionized our understanding of planetary habitability.

The journey began with NASA’s Kepler mission, which opened the floodgates to the discovery of thousands of exoplanets, planets beyond our solar system. Among these, a select few have been found within the coveted habitable zone, a region around a star where conditions could potentially support liquid water, a key ingredient for life as we know it.

One of the earliest and most celebrated discoveries was Kepler-186f, a rocky planet approximately 500 light-years away from Earth. Similar in size to our home planet and orbiting within its star’s habitable zone, the discovery of Kepler-186f in 2014 marked a significant milestone in the search for Earth-like planets.

New Discoveries

In 2017, the discovery of a system of seven Earth-sized planets orbiting a dim red dwarf named TRAPPIST-1 further piqued the interest of the scientific community. Three of these planets, named e, f, and g, were found within the habitable zone. Their size and proximity to each other made them ideal candidates for atmospheric analysis. However, subsequent studies raised concerns about the extreme stellar flares of their host star, which could potentially strip away their atmospheres, casting a shadow over their habitability.

Closer to home, the discovery of Proxima b in 2016, a mere 4.2 light-years away, sparked global interest. Slightly larger than Earth and orbiting within a potentially temperate zone, Proxima b seemed a promising candidate for life. However, its parent star, Proxima Centauri, is known for its volatility, raising doubts about the planet’s long-term habitability.

In recent years, LHS 1140 b, a dense, rocky planet 40 light-years away, has emerged as a strong contender in the search for extraterrestrial life. With a stable orbit and early indications of an atmosphere, it is a prime target for upcoming investigations by the James Webb Space Telescope (JWST).

The Spotlight on K2-18b

Adding to the growing list of potential life-supporting planets is TOI 700 d, confirmed in 2020 by NASA’s TESS observatory. Receiving nearly the same amount of light as Earth and orbiting a quiet red dwarf, it raises hopes for a relatively undisturbed environment. However, atmospheric data remains elusive, leaving its habitability status uncertain.

The current spotlight, however, is on K2-18b, a sub-Neptune-sized planet first identified in 2015. Located 124 light-years away, the planet has shown signs of water vapor, methane, and carbon dioxide. In 2023, astronomer Nikku Madhusudhan and his team reported faint traces of dimethyl sulfide (DMS), a molecule produced on Earth only by life. New observations in 2025 using a different JWST instrument strengthened the case for DMS and a related compound, dimethyl disulfide (DMDS).

Despite these promising findings, experts urge caution. Dr. Ryan MacDonald of the University of Michigan stated, “These new JWST observations do not offer convincing evidence that DMS or DMDS are present.” Others, like NASA’s Nicholas Wogan, have acknowledged the improved data but stress the need for independent verification.

The consensus among scientists is that while these planets show potential, confirming life—or even just conditions for it—remains an immense challenge. The “five-sigma” statistical confidence required to claim a discovery in physics is still a long way off for most of these detections.

As we continue to explore the cosmos, we are reminded of the words of Dr. Thomas Beatty of the University of Wisconsin-Madison, who encapsulated the current state of affairs, saying, “Right now, we’re seeing a lot of ‘maybes.’” He added, “But even a maybe is remarkable, considering how far we’ve come.”

The search for extraterrestrial life has transformed our place in the cosmos—from passive observers to active explorers of worlds that, not so long ago, existed only in science fiction. As technology advances and instruments like JWST continue to refine their vision, the quest continues, reminding us of the vastness of the universe and the potential it holds.

Are UFO revelations true? Buzz Aldrin clears lie detector test on UFO sighting

Astronauts Buzz Aldrin, Al Worden, Edgar Mitchell and Gordon Cooper have one thing in common, they are among the ardent defenders of UFO theory and claimed to have seen or chased many during their space travels. Now, all the four have cleared a lie-detector test, which reiterates their claim.

The lie detector test was carried out using the latest technology and experts said they were “completely convinced” with the results that they are telling the world truth about signs of alien life.

Buzz Aldrin, now 88, was the second human alogn with Neil Armstrong to set foot on the moon in their historic Apoll 11 mission in 1969. He claimed later that he saw a UFO. “There was something out there that was close enough to be observed, sort of L-shaped,” he said repeatedly.

The Institute of BioAcoustic Biology in Albany, Ohio, which has conducted the test, preferred to keep its technology top secret though. They have claimed that they used complex computer analyses of the astronauts’ voice patterns and more reliable than current lie detector tests.

Edgar Mitchell, another who took the test was the sixth astronaut to walk on the moon, who had earlier claimed that “aliens have contacted humans several times”.

Al Worden, 86, who had piloted the Apollo 15 mission revealed similar views to Good Morning Britain viewers with his claims earlier to have seen extra-terrestrials. In addition, the voice recordings of Edgar Mitchell and Gordon Cooper, both now dead, were also analysed by the Ohio-based institute.

Mitchell was part of the Apollo 14 mission and Cooper was also a space pilot who claimed to have chased UFOs during his flights.

Aldrin has been in the news recently for advocating an affordable plan to get humans to Mars.

Since Earth does a lap of the Sun once every 365.256 days and Mars too does a lap of the Sun once every 686.93 Earth days, he said we can overlay these two orbits with a third orbit, that of a spacecraft, which takes 2 and 1/7th years to complete. This spacecraft can meet up with the two planets, he said.

Instead of using fuel to change direction, the spacecraft could use gravitational slingshot manoeuvres to reduce the cost of each trip, he explained.

NASA Denies Anonymous Video on Alien Life Discovery Announcement

US space agency NASA has denied global hackers group Anonymous claim that it is going make announcement on the discovery of alien life, said a spokesman.

Last week, the hacking group Anonymous posted a video on YouTube that said NASA is about to announce the discovery of life in our galaxy but NASA scientist beyond Earth.

“Contrary to some reports, there’s no pending announcement from NASA regarding extraterrestrial life,” said NASA science chief Thomas Zurbuchen in a tweet.

“Are we alone in the universe? While we do not know yet, we have missions moving forward that may help answer that fundamental question,” Zurbuchen said.

In fact, Anonymous has put out its video based on Zurbuchen’s testimony to the House of Representatives’ Committee on Science and Space in April this year. However, NASA has always maintained that there is no discovery of alien life and Anonymous video (see below) has surprised many.

Anonymous on their website said, “NASA says aliens are coming!” and  uploaded the above video citing alien-friendly comments made by NASA astronauts and space scientists.

Anonymous quoted Zurbuchen’s rendering before a Congressional hearing in April titled “Advances in the Search for Life” that said: “NASA`s recent advances, such as the discovery of hydrogen in Saturn`s moon Enceladus and the Hubble team’s promising results from the oceans of Jupiter`s moon Europa, are promising signs that we’re closer than ever to discovering evidence of alien life.”

“Taking into account all of the different activities and missions that are specifically searching for evidence of alien life, we are on the verge of making one of the most profound, unprecedented, discoveries in history,” Zurbuchen said. Perhaps the second part of the quote has made Anonymous see NASA forthcoming with an announcement.
