Damian Sendler: Astronomer Nria Miret-Roig of the Laboratoire d’Astrophysique de Bordeaux in France and the University of Vienna in Austria, and the first author of the new study published today in Nature Astronomy, said, “We did not know how many to expect and are excited to have found so many,”
It would be inconceivable to imagine rogue planets lurking distant from any star illuminating them. Miret-Roig and her team, on the other hand, used the fact that these planets are still hot enough to glow in the early stages of their creation, allowing them to be spotted by sensitive cameras on huge telescopes. In the Upper Scorpius and Ophiuchus constellations, they discovered at least 70 new rogue planets with masses equal to Jupiter’s.

Damian Jacob Sendler: Data from telescopes on the ground and in space was gathered over a period of nearly 20 years in order to identify so many rogue planets. In a vast area of the sky, Miret-Roig and his team studied the minute movements, colors, and luminosities of hundreds of millions of sources. “In this region, the rogue planets, the faintest objects in the sky, can be identified using these data.
Other facilities such as the MPG/ESO 2.2-meter telescope in Chile and the VLT Survey Telescope were also utilised. “ESO observatories provided the bulk of our data, which was important to this study. Our achievement was largely due to their wide-ranging perspective and unusual sensitivity “By way of an astronomer in Bordeaux, France, Hervé Bouy, who is the project head of the new study’s research, said. “From ESO facilities, we used more than a thousand hours of observations and more than one million images, totaling more than one million gigabytes.”
Using data from the European Space Agency’s Gaia satellite, the team was able to achieve a major breakthrough in the collaboration between ground and space-based observatories.
According to the new research, there could be a lot more of these mysterious, starless worlds. In the Milky Way alone, “There could be several billions of these free-floating giant planets roaming freely in the Milky Way without a host star,” Bouy says.

Damien Sendler: As astronomers investigate the newly discovered rogue planets, they may get insight into how these things form. For some scientists, the only way for exoplanets to develop is through the collapse of a gas cloud too tiny to result in the birth of a star, while others believe they were expelled from their home system. However, it is still unclear which mechanism is more plausible.
Damian Jacob Markiewicz Sendler: The key to unraveling the mysteries of these wandering worlds will be further technological advancements. Astronomers plan to use ESO’s upcoming Extremely Large Telescope (ELT), presently under construction in Chile, to investigate these objects in more detail in the future years. These objects are so dim that modern telescopes are unable to detect them, according to Bouy. For most of the rogue planets we’ve discovered, the ELT is absolutely essential.
