Alien world ‘home to Star Trek’s Spock’ is ‘space illusion’ as scientists warn we’re being tricked by mystery
STAR Trek fans are disappointed to learn that Vulcan — the home planet of the beloved character Spock — does not really exist in our galaxy, as previously thought.
Scientists first came across what they believed to be a small planet orbiting the star 40 Eridani A, where Spock is said to have grown up, in 2018.
Researchers even noted at the time, however, that the transit method is most accurate when observing larger supposed planets, and could give false positives for smaller bodies.
This appears to be what happened in the case of Vulcan.
The radial velocity method uses high-precision instruments based atop Kitt Peak in Arizona to measure "wobbles" in starlight as the gravity of a star pulls at the planet's light.
The resulting information is more accurate than what could be gleaned using the transit method and firmly led scientists to conclude that the variations in light reported five years ago were actually just stellar light bouncing around unexpectedly.
LOOKING FOR LIGHT
Five years ago, scientists believed that this potential Vulcan had a 42-day orbit around HD 26965, a Sun-like star, that exists about 16 light-years away.
They believed that they had found evidence of a super-Earth, which is a planet larger than the Earth but smaller than Neptune.
But the original researchers also noted that these 'light dances' could possibly explain their findings, instead of there being a Vulcan-like planet.
The addition of an instrument known as NEID to the Kitt telescope changed those calculations.
Like other radial velocity instruments, NEID relies on the Doppler effect to measure shifts in the light spectrum of a star.
Measuring the different wavelengths emitting from a planet can produce a highly accurate picture of the celestial body's movements.
These wobbling motions can then be used to estimate the size and composition of the planet in question.
Dartmouth scientists said they believe the initial error came from observing a flickering of something on the star's surface or rays from a solar flare.
PLANET VULCAN DOOMED
Spock is one of Star Trek fans' most beloved characters in the long-lasting sci-fi series, played for years by actor Leonard Nimoy.
He first appeared as a science officer aboard the original starship USS Enterprise from the 1960s, and his mixed human-Vulcan heritage played a role in several plot points.
What is an exoplanet?
Here's what you need to know...
- An exoplanet is a planet that is located outside of our solar system and is orbiting its own star, like how Earth orbits the Sun
- They are very hard to see with telescopes because they are often hidden by the brightness of their star
- Nasa sent the Kepler space telescope into orbit to find Earth-sized exoplanets that might support life
- Over 5,500 exoplanets have been discovered so far, and more missions to find even more exoplanets are planned
- A good way to spot an exoplanet is to look for wobbly stars, because a disruption to starlight can indicate that a planet is orbiting it and therefore blocking out light on occasion
- Exoplanets are very common in the universe, and the more we find that look like Earth, the closer we get to knowing whether we're alone out there
With his bowl-cut hair and deadpan eyes, Spock popularized the now-famous Star Trek greeting made by raising your hand and separating your pinky and ring fingers from your index and middle fingers.
In the series, Spock often talked about his home planet Vulcan and how his culture varied from that of the other characters.

Although Vulcan survived many deadly battles throughout most of the series, the planet was destroyed in the 2009 film by a Romulan villain named Nero.
The fictional Vulcan was consumed by a man-made black hole — not so different to how some fans see the discovery and later 'disappearance' of the real-life Vulcan.
