Astronomers Stumble Upon the Faintest Exoplanet Ever Imaged from Earth
A team of skilled astronomers at the University of Edinburgh has made a groundbreaking discovery, finding the faintest exoplanet ever imaged from Earth. This remarkable find has been hiding in plain sight in images dating back at least 11 years, according to a study released in The Astrophysical Journal Letters.

The discovery was made by Ben Sutlieff, an astronomer at the University of Edinburgh and co-lead of the study, who called the discovery a ‘serendipitous’ one. The team initially aimed to study a known planet orbiting the star Beta Pictoris using the European Southern Observatory’s Very Large Telescope and observe how it changed over time.
However, when they analyzed their images, they stumbled upon another, previously unknown planet. ‘There’s something else there; did you see it?’ Markus Bonse, the other co-lead of the study, remembered saying. The group then looked through the ESO archive and found the new planet in images going back at least 11 years. In one image, it was barely visible against Beta Pictoris’ first-known planet, called Beta Pictoris b.
A New Planet Discovered: Beta Pictoris d
The new planet is called Beta Pictoris d and is 63 light-years away from Earth. It’s a gas giant, similar to the two other planets in its solar system, as well as Jupiter and Saturn in our system. Beta Pictoris d has a much wider orbit than Beta Pictoris b and Beta Pictoris c.
It’s unusual, as well as difficult, to take a direct image of a planet as faint as Beta Pictoris d. Direct imaging captures the light from an object, so it only works with planets that show up next to their (much brighter) stars. Bonse said the new planet is 100 times fainter than Beta Pictoris b.
A Second Discovery by Another Team
Another team, led by Aiden Gibbs of the University of California in the United States, also discovered Beta Pictoris d using the James Webb Space Telescope. The Astrophysical Journal Letters has published their results today, making it a significant moment in the field of astronomy.
This discovery highlights the importance of continued exploration and observation of our universe. With the help of advanced technology and skilled astronomers, we are able to uncover secrets that were previously unknown, expanding our understanding of the cosmos.
The discovery of Beta Pictoris d is a testament to the power of collaboration and perseverance in the field of astronomy. It also serves as a reminder of the vast mysteries that still await us in the universe, and the importance of continued exploration and discovery.
