Scientists identify 10,000 'impossible' exoplanet candidates, potentially tripling the number of known alien worlds

How many exoplanets are there? A new survey put the number at over 10,000.  But how many of them harbour life is difficult question, as only the creator can create life-giving minerals and other elements to a planet.

Since the first alien planet was spotted in 1995, the number of exoplanet discoveries has slowly risen in line with new technologies, such as the James Webb Space Telescope, which are better equipped to spot these weird alien worlds. In September 2025, astronomers revealed that the number of confirmed exoplanets had surpassed 6,000, and nearly 300 have been added to the list since then, according to NASA.

But in a new study uploaded April 20 to the preprint server arXiv, researchers report that they've uncovered an astonishing 11,554 exoplanet candidates at once. If all of them can be confirmed, it would bring the total number of exoplanets to nearly 18,000, which is almost triple the current total.

Using a machine learning algorithm, the team analyzed the light curves of precisely 83,717,159 stars captured by NASA's Transiting Exoplanet Survey Satellite (TESS), a car-sized space telescope that has been circling Earth since 2018. By looking for subtle dips in the stars' brightness, astronomers can tell when a planet has likely passed in front of, or transited, its home star.

This revealed more than 11,000 exoplanet candidates, of which 10,052 had never been seen before. Around 87% of the candidates were spotted transiting twice or more, allowing the researchers to calculate the planets' orbital periods, which range from 0.5 to 27 days, according to StellarCatalog.com.

Using one of the 21-foot (6.5 meters) Magellan telescopes in Chile's Atacama Desert, the team identified a "hot Jupiter" exoplanet, dubbed TIC 183374187 b, that orbits a star around 3,950 light-years from Earth — right where the algorithm predicted.

TESS was specifically designed to detect transiting objects, and it has already discovered 882 confirmed exoplanets — roughly 14% of the current total — so it may seem strange that no one has seen most of the new candidates until now.

Most researchers prioritize analyzing the light curves of the brightest stars in the TESS dataset, because transit events for these stars are much more noticeable and easier to confirm. But there are many more faint stars that end up being captured in the telescope's wide-field photos.

Space is wonderful, but stars can be fickle. Some exoplanets seem to change their composition oddly. This happened to a star that is about to explode as a supernova.

”One of the largest stars in the known universe is undergoing a strangely rapid transformation and may soon explode as a supernova.

First catalogued in 1981, WOH G64 sits some 160,000 light years from Earth in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way. It is one of the biggest red supergiants, the largest stars we know of. These are massive, cool stars that have run out of hydrogen fuel in their core and instead burn an envelope of hydrogen gas that surrounds them.”

The more we know about exoplanets, the mysterious they become.  Now a planet with a large volcanic  world has just ben found.

“An alien world with a seemingly sulphur-filled atmosphere may be the most volcanic planet astronomers have ever spotted.

We have never directly detected volcanic activity outside our solar system, in part because current telescopes aren’t powerful enough to take images of exoplanets’ surfaces. We might be able to spot alien volcanoes by measuring the gases they pump into a planet’s atmosphere, but this is also at the very limit of what current telescopes can do – there have been tantalising hints of atmospheres on rocky surface.”

Will this exoplanet have life?

K2-18 b is a large world located about 120 light-years from the sun. It inhabits the Goldilocks zone around its star, meaning at liquid water (and potentially life) could exist there.

A recent analysis with the James Webb Space Telescope (JWST) supports the idea that the exoplanet may have its own liquid water ocean — and that the ocean may be home to living creatures. But probably not little green men.

In the study, JWST detected possible traces of dimethyl sulfide, a chemical known to be emitted only by phytoplankton on Earth, in the exoplanet's atmosphere.

But scientist have been adamant that such things happened on  Venus, which will not support life.

Some scientisst think that the oldest continents in our galaxy were created when our  galaxy came unto bemg. This is according to recent research told us, , 

“Astrobiologists think a planet needs to have certain features to support life: oxygen in its atmosphere, something to shield organisms from dangerous radiation and liquid water, for a startldest continents in our galaxy may have arisen 5 billion years before Earth’s, new research suggests — and that means there may be multiple worlds in the Milky Way harboring alien life even more advanced than our own.”

This is what evolution believing astrobiologist, for instance  Jane Greaves, an astronomer at Cardiff University says.

She said; “two exoplanets' continents — and perhaps life — may have arisen four to five billion years before Earth's.,"

But onlt God can create continents.

NASA has found two super earths, while the planets are far too hot and cannot support life

The star HD 260655 is cooler and dimmer than our sun, the proximity of the planets to the red dwarf means the worlds would be way too hot for life. 

HD 260655b has an average temperature of 435 degrees Celsius or 816 degrees Fahrenheit, while HD 260655c is milder but still a fiery (284 degrees Celsius) or 543 degrees Fahrenheit. 

Not all super earhs can harbour life.

Mystery for Darwinism

The Universee is full of dilemmas, that Darwinism cannot explain, Now, a star called AU Microscopii seems to contain strange pockets of hydrogen thousand of degrees colder than the rest of the star, and astronomers aren’t sure why.

They think that . the star “AU Microscopii may have mysterious cold spots. It seems to contain pockets of hydrogen that are more than 1500°C colder than the surrounding areas, and astronomers aren’t sure why.

AU Microscopii, or AU Mic, is a relatively small star about 32 light years away. Laura Flagg at Cornell University was testing an algorithm using data on AU Mic taken by the Hubble Space Telescope in 1998.”

Now, planets, moons and exoplanets are not so old as Darwinians suppose.. Some stars are  older than the universe.

Astronomers say they have spotted signs of what may be an enormous exomoon orbiting a planet more than 5000 light years away. If it is real, it could be the first exomoon we have found, but the detection isn’t conclusive.

This exomoon may be orbiting a planet called Kepler-1708b. 

 David Kipping and his colleagues found an exomoon orbiting a planet known as a super-Jupiter.  

 Some astronomers, like Rene Heller, are not so sure the finding is an exomoon. There are many things in the universe that baffle a human mind.

No live on Venus - that might have been dry for ages .

 A few weeks ago, the  science papers were shouting there’s live on Venus, However, now it seems that it is not – and has been not habitable.

For the past decades, Venus has been seen as a potential abode for life. For instance, models  based on evolution have said that Venus had bog oceans that they thought wuuld have kerpt live going for millions of years.

For live to endure, it has to float - floating in the clouds about 30 miles (50 kilometers) up, where temperatures and pressures are similar to what we enjoy at sea level here on Earth. 

 

However, the new study, which was published online Wednesday (Oct. 13) in the journal Nature, scientists led by Martin Turbet, a postdoctoral researcher at the Geneva Astronomical Observatory in Switzerland, simulated the climate of ancient Venus using a new model. And they came up with very different results. 

 

If the scientist are right, Venus has always been warm and dry, as it is today.

 

This has a message also for exoplanets: The ones  that orbit near the inner edge of the conventional habitable zone, where liquid water can exist on a planet’s surface, might not actually be habitable," the authors write.

No little green men in the universe

Just 5 years ago, physicists opened a new window on the universe when they first detected gravitational waves, ripples in space itself set off when massive black holes or neutron stars spiral together. Even as discoveries pour in, researchers are already planning bigger, more sensitive detectors.

 And a Ford versus Ferrari kind of rivalry has emerged, with scientists in the United States simply proposing detectors 10 times bigger than the ones they have now, and researchers in Europe pursuing a more radical design that would combine six detectors in a single underground observatory. Researchers say detectors 10 times more sensitive than the ones they have now could detect all black hole mergers within the observable universe and spot hundreds of mergers of neutron stars, laying bare the nature of the ultradense matter in neutron stars. But, it's early days for the U.S. project, which is called the Cosmic Explorer, and the European project, which is known as the Einstein Telescope.

However, no little green men  the universe have been detected, Life cannot come about by Darwinian ways. It has to be created.

All attempts to listen to alien sounds have turned out to be false. For instance, an interstellar cloud destroys belief in aliens and all subsequent attempts have been futile.

New Scientist has said that aliens are more likely than God.

But only if we a priori rule out the 
God who in the beginning created everything.

Life cannot create itself.

Astronomers Hunting For Radio Signals See Them From Proxima Centauri

Astronomers hunting for aliens have detected an intriguing signal from the direction of Proxima Centauri nearest star system to the sun, The Guardian reported.

 

Space signals tend to be false alarms. Not even the infamous wow-signal was probably cause by a comet, not aliens.

 

 So, the question is-the who made universe? Regardless of what evolutionist think, the universe cannot have come about by change.it has to have a designer, who designed it very well.

 

Now, evolution believing scientists are hoping that this new signal would bring a solution of who designed the universe and  us.

Planets More Hospitable To Life Than Earth May Already Have Been Discovered

Astronomers have discovered more than 4,000 exoplanets, or planets outside our solar system, so far. even the planet that most resembled the Earth, is not habitable,

For example, planet KELT-9b is so hot that its atmosphere is constantly melting. The darkest known planet, TrES-2b, has an atmospheric temperature of 980 degrees Celsius or1,800 degrees Fahrenheit. On the other end of the inhospitable spectrum is GJ 433 d, whose discoverers described it as the coldest Neptune-like planet ever discovered. 

However, according to evolutionists, at least two dozen planets outside the solar system might be better for life than  Earth,

These planets are just a little older, a little wetter, a little warmer and a little larger than Earth is, researchers wrote Sept. 18 in the journal Astrobiology. All of these factors could mean that some of these planets are the best places to search for extraterrestrial life. 

"We have to focus on certain planets that have the most promising conditions for complex life. However, we have to be careful to not get stuck looking for a second Earth because there could be planets that might be more suitable for life than ours," University of Washington astrobiologist Dirk Schulze-Makuch said .

 A better version of Earth might also have a slightly larger moon, or a moon slightly closer to the planet, which would help stabilize its orbit and prevent life-disrupting wobbles, the researchers wrote. 

 The researchers came up with a set of parameters to use to meet all these criteria. According to them,  the perfect superhabitable planet would be in orbit around a K dwarf star, which is a relatively small star star that’s slightly cooler than our sun (which is considered a yellow dwarf); about 5 billion to 8 billion years old; about 10% larger than Earth; about 9 F (5 C) warmer than Earth, on average; moist with an atmosphere that is 25% to 30% oxygen, with scattered land and water. The perfect planet would also have plate tectonics or a similar geological process in order to recycle minerals and nutrients through the crust and to create diverse habitats and topography, and would have a moon between 1% and 10% of its size orbiting it at a moderate distance.

It's not possible to evaluate distant exoplanets on all these criteria. There is no way to calculate an exoplanet's landmass area, for example, much less how it's distributed. 

So, this research did not come up with “more hospitable than Earth” criteria. Even if a super Earth was found, life has to be planted there – by God.

Some Exoplanets Are Just Weird


Kraus et al., 2020.

Joel Kontinen

Some exoplanets are just weird. The latest one seems to orbit three suns, which would make it into a   tatoiine planet, like the famed sun in Luke Skywalker's twin-sunned homeworld.

“Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the centre, and a third star swirling around its siblings from several hundred million miles away.”

Unlike evolutionists speculate, we would not expect to see little green men on as GW Orionis.
