Scientists in Spain have taken a major step in protecting Earth from a potential asteroid collision. A study published in ‘Monthly Notices of the Royal Astronomical Society’ highlights a new formula that uses the gravitational bending of light to determine the precise location of celestial bodies, including potentially dangerous asteroids.
Oscar del Barco Novillo, a professor from the University of Murcia who led the research, explained his formula for calculating the angle of light deflection caused by massive objects such as the Sun.
“This could have implications for the precise position of distant stars, as well as the precise location of minor solar system objects such as asteroids, to better estimates of their orbits. As a result, various branches of astronomy and astrophysics, such as celestial mechanics or stellar dynamics, can benefit from these new results,” said Novillo, quoted from Phys.
Gravitational bending and its meaning
By considering phenomena first identified by Isaac Newton and later confirmed by Albert Einstein, the researchers found a way to determine the precise positions of minor objects in the solar system.
In a new paper published in the Monthly Notices of the Royal Astronomical Society, researchers have proposed accurate calculations of the gravitational bending angle of light (GBL) by static massive objects, such as the sun or slow-moving planets.
“Our study, which is based on a geometric optical model, provides precise equations for the most accurate calculation to date of GBL angles by static massive objects, such as the sun or the planets of the solar system,” said Novillo
Light from distant objects often bends under the influence of strong gravitational fields, making them appear displaced from their actual position.
Novillo’s equation is the most accurate to date, taking into account the position of the observer and source relative to the gravitational mass. According to NASA’s Catalina Sky Survey, about 2,000 asteroids larger than 460 feet are discovered near Earth each year.
This is important because it can allow astronomers to determine the exact location of asteroids and minor objects in the solar system. This provides a more accurate calculation of its orbit around the sun and makes it easier to find objects that could potentially harm Earth.
Increases planetary defense
The application of this formula is not only limited to asteroid discovery. This formula could help perfect planetary defense systems, such as NASA’s DART mission, which in 2022 succeeded in changing the trajectory of the asteroid Dimorphos using satellite collisions.
Initial observations from the mission show promising results, with detailed findings expected from the European Space Agency’s Hera mission next year.
Additionally, the new approach could be important in mapping distant galaxies and exploring cosmic phenomena such as dark matter and dark energy.
“Distant galaxies distorted by disturbing masses can now be found precisely,” said Novillo, quoted by the Daily Mail.
The implications of Novillo’s formula extend to mapping nearby stars and their exoplanets. For example, this formula can help determine the exact position of Proxima Centauri, which is 4.25 light years away, thereby helping scientists study potentially habitable planets.
The formula could also help ESA’s Euclid mission, which aims to create detailed 3D maps of billions of galaxies over the next six years.
With these innovative equations, scientists are better equipped to detect, understand, and potentially mitigate cosmic threats while delving deeper into the mysteries of the universe. (Z-3)

Jimmy Carr (in his signature dry tone): “Ah, asteroids. The universe’s way of saying, ‘You know what? I’ve had enough of your species.’ But don’t worry, folks, scientists in Spain have come up with a new formula to help us avoid becoming space splats. Because, you know, that’s exactly what we need – more math.”
(Rowan Atkinson, aka Mr. Bean, makes a goofy face in the background, holding a sign that reads “Asteroid Dodging 101”)
Ricky Gervais (in his cheeky tone): “Now, I know what you’re thinking. ‘A new formula? How exciting!’ No, really, it is. I mean, who doesn’t love a good equation? It’s like the universe’s version of a Sudoku puzzle. ‘Oh, I’ve got a 9, where’s the 5?’ Ah, no, wait, that’s just a massive asteroid hurtling towards us.”
Lee Evans (in his fast-talking, energetic tone): “Hold on, hold on, guys! This is serious business! We’re talking about protecting our planet from potentially hazardous asteroids. I mean, can you imagine the headlines? ‘Asteroid Destroys Earth: Scientists Say, “We told you so”‘. No, no, no! We need to take this seriously. Unless, of course, we’re all just going to end up as space dust anyway. In which case, carry on.”
Jimmy Carr: “Right, so the scientists at the University of Murcia have developed this fancy formula that uses the gravitational bending of light to determine the precise location of celestial bodies. Because, let’s face it, we all know that gravity is just a fancy word for ‘the universe’s way of messing with our heads’.”
Rowan Atkinson (in a silly voice): “Gravity, gravity, gravity… it’s like the universe’s version of a big, invisible hug. ‘Come here, asteroid, let me squeeze you into oblivion’.”
Ricky Gervais: “And the best part? This formula can also be used to map distant galaxies and explore cosmic phenomena like dark matter and dark energy. Because, you know, we haven’t got enough mysteries to solve on our own planet. Let’s go solve some universe-sized puzzles!”
Lee Evans: “I mean, think about it, guys. With this formula, we can finally get accurate calculations of the gravitational bending angle of light. It’s like the universe’s version of a Google Maps update. ‘Recalculating… recalculating… Ah, yes! That asteroid is definitely going to hit us’.”
Jimmy Carr: “So, there you have it, folks. A new formula to help us avoid becoming asteroid fodder. Because, as we all know, the universe is just waiting for us to let our guard down. ‘Oh, humans, you think you’re so smart with your formulas and your space suits? Ha! I’ll just send a big rock your way and see how you like it’.”

Jimmy Carr: “Thanks for joining us on this journey into the world of asteroid dodging. Until next time, when we’ll probably be talking about the impending doom of humanity… ”
Rowan Atkinson (in a silly voice): “Asteroid, asteroid, go away… come again another day… when we’ve got a better formula…”
