A distant signal from space has helped astronomers to confirm the existence of a planet outside our solar system that could be capable of supporting life.
The exoplanet, called HD 20794 d, orbits a star similar to our Sun. It is 20 light-years away, which is so close in cosmic terms that future, more advanced telescopes could be used to capture direct images of the stellar discovery.
It was first detected two years ago by Michael Cretignier, a researcher at the University of Oxford, but its existence has now been confirmed using data from advanced planet-hunting space instruments in Chile.
HD 20794 d is one of the most exciting exoplanets discovered so far and offers astronomers an opportunity to study a world that may share some similarities with Earth.
“For me, it was naturally a huge joy when we could confirm the planet's existence,” Mr Cretignier said. “It was also a relief, since the original signal was at the edge of the spectrograph’s detection limit, so it was hard to be completely convinced at that time if the signal was real or not. Excitingly, its proximity to us means there is hope for future space missions to obtain an image of it.”
Findings from the research have been published in the Astronomy & Astrophysics journal.
Mystery signal
The exoplanet was first detected because of tiny changes in the light spectrum of its host star, which were seen using archived data from the High Accuracy Radial velocity Planet Searcher (Harps) spectrograph and the Echelle Spectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (Espresso) instrument.
These shifts suggested something was pulling on the star with its gravity. But the signal was so faint that there that was still doubt about what was causing it. It could have been caused by the star itself, or an error in the instruments.
Mr Cretignier and an international team of researchers used more than 20 years of data from the two instruments to verify the signal and confirm the Earth-like exoplanet.
Earth similarities
What makes HD 20794 d so special is its location in the habitable zone, the region around a star where temperatures are just right for liquid water.
But unlike Earth, the exoplanet does not have a near-circular orbit. Instead, its path around the star is elliptical, meaning its distance from the star changes over the course of its year.
Jonathan Ward, a fellow of the UK’s Royal Astronomical Society, who was not involved in the study, explained how an elliptical orbit could affect the likelihood that the exoplanet can host life.
“For liquid water to exist, a planet’s temperature has to stay in the right range. If the orbit is too elliptical, the planet might swing too close to its star, making it too hot, or drift too far away, making it too cold,” he told The National. “It’s not clear yet how that would affect the potential for life to form and evolve.”
Strange Earth-like planets that lie beyond our solar system
Another factor is the exoplanet’s size, but the researchers have to wait until more advanced telescopes have been developed to determine how big the celestial body is.
"At the moment the best we can say is that its minimum mass is six Earth-mass and there is 75 per cent of chance that the planet is smaller than 10 Earth-mass," Mr Cretignier told The National. "Direct imaging data will allow us to reconstruct the 3D orbit of the planet, leaving this fundamental degeneracy and providing the real mass of the exoplanet."
Telescope projects, including the Extremely Large Telescope (ELT) and the Large Interferometer For Exoplanets (Life), could revolutionise the study of HD 20794 d. The ELT could take images of the planet directly, revealing its true mass and atmospheric composition, while Life would analyse its atmosphere for water vapour and potential biosignatures, offering deeper insights into its habitability.
Searching for water
Mr Cretignier said that, if these telescopes are developed, he would prioritise the search for water molecules in the exoplanet's atmosphere. "After all, it is well-accepted that searching for life is useless if there is no water to sustain this life," he said.
If there are water molecules, another indicator of life could be biosignatures. These are chemical markers, such as oxygen or methane, in a planet's atmosphere that could indicate the presence of life.
"So far as I know, there are no perfect biosignatures at the moment, even if some species are often mentioned," Mr Cretignier added. "For instance, we know that life began on Earth well before leaving an active or detectable trace in the Earth's atmosphere.
"Similarly, some geophysical phenomena can mimic the signatures of life or thick clouds/haze may hide them so we should be very careful here."

UK's plans to cut net migration
Under the UK government’s proposals, migrants will have to spend 10 years in the UK before being able to apply for citizenship.
Skilled worker visas will require a university degree, and there will be tighter restrictions on recruitment for jobs with skills shortages.
But what are described as "high-contributing" individuals such as doctors and nurses could be fast-tracked through the system.
Language requirements will be increased for all immigration routes to ensure a higher level of English.
Rules will also be laid out for adult dependants, meaning they will have to demonstrate a basic understanding of the language.
The plans also call for stricter tests for colleges and universities offering places to foreign students and a reduction in the time graduates can remain in the UK after their studies from two years to 18 months.

Electoral College Victory
Trump has so far secured 295 Electoral College votes, according to the Associated Press, exceeding the 270 needed to win. Only Nevada and Arizona remain to be called, and both swing states are leaning Republican. Trump swept all five remaining swing states, North Carolina, Georgia, Pennsylvania, Michigan and Wisconsin, sealing his path to victory and giving him a strong mandate.
Popular Vote Tally
The count is ongoing, but Trump currently leads with nearly 51 per cent of the popular vote to Harris’s 47.6 per cent. Trump has over 72.2 million votes, while Harris trails with approximately 67.4 million.
