Unveiled by the James Webb Space Telescope, fresh imagery has unveiled unprecedented twin-like celestial entities in the Orion Nebula, previously unnoticed by scientists.

The Orion Nebula, a luminous mist of particles and gases, stands out as one of the most brilliant nebulae in the night sky and is recognizable as the sword within the Orion constellation. Situated 1,300 light-years away from Earth, this nebula has fascinated astronomers for a long time, offering them a treasure trove of celestial objects to observe, such as disks around young stars that give rise to new planets and brown dwarfs, which are objects with a mass between that of planets and stars.

To capture the wonders of the Orion Nebula in unprecedented detail and to unveil unexpected findings, astronomers employed NIRCam, the near-infrared camera of the Webb telescope. This sophisticated instrument allowed them to create intricate mosaics of the nebula using both short and long wavelengths of light.

Astronomers Samuel G. Pearson and Mark J. McCaughrean observed the Orion Nebula's short-wavelength image, specifically focusing on the Trapezium Cluster. This cluster is a youthful star-forming region that is approximately 1 million years old and contains numerous newly formed stars. Apart from these stars, the researchers also identified brown dwarfs, which are too small to initiate nuclear fusion in their core and thus do not become stars. Brown dwarfs have a mass less than 7% of the sun's mass.

While searching for other low-mass objects, the astronomers made a remarkable discovery. They encountered pairs of planet-like objects with masses ranging between 0.6 and 13 times the mass of Jupiter. These findings challenge certain fundamental astronomical theories.

The scientists named them JuMBOs, which stands for Jupiter Mass Binary Objects. Pearson, a research fellow at the European Space Agency, stated that while some of them are heavier than Jupiter, they will be approximately the same size or just slightly larger.

The astronomers made a remarkable discovery of 40 pairs of JuMBOs and two triple systems, all revolving around each other in wide orbits. While these celestial objects exist in pairs, they generally maintain a separation of approximately 200 astronomical units, equivalent to 200 times the distance between Earth and the sun. It takes anywhere from 20,000 to 80,000 years for these objects to complete a full orbit around each other.

The temperatures of the objects vary from 1,000 degrees Fahrenheit (537 degrees Celsius) to 2,300 F (1,260 C), according to Pearson. These gaseous objects are relatively young, around 1 million years old in astronomical terms. In comparison, our solar system is approximately 4.57 billion years old.

McCaughran, the senior adviser for science and exploration at the European Space Agency, explains that these objects in Orion are like 3-day-old babies when compared to the lifespan of the sun. Despite their young age, they emit a significant amount of light and heat because the energy they possess when they are created allows them to glow, enabling us to observe them. McCaughran and Pearson have conducted research on the Orion Nebula using the Webb telescope and have written two research papers on their findings. These studies have been submitted for publication in academic journals, and the preliminary findings can be accessed on the preprint site arXiv. However, many mysteries still surround these massive gaseous objects, including their origin.

JuMBOs: Disrupting the norms of astronomy

The birth of stars occurs when immense clouds of gas and dust succumb to gravitational forces, causing them to collapse. This ongoing process leads to the creation of disks comprised of gas and dust that revolve around these stars, ultimately giving rise to planets. Nevertheless, the origin and presence of JuMBOs within the Orion Nebula remain an enigma, as current theories fail to provide a satisfactory explanation.

Some may view the JuMBOs as akin to rogue planets, which are planetary-mass objects that wander freely through space, devoid of any stellar orbits. However, numerous rogue planets initially start off by orbiting stars before getting ejected. Consequently, it becomes challenging to rationalize how two of these objects were simultaneously expelled while still maintaining their gravitational connection to one another.

"Scientists have dedicated decades to studying and developing theories and models regarding the formation of stars and planets. However, none of these theories could have predicted the existence of pairs of super low mass objects drifting through space - a phenomenon that is being observed frequently," stated Pearson. "This discovery indicates a fundamental flaw in our understanding of either planet formation, star formation, or both."

"The Orion Nebula is highly regarded among astronomers as a favored subject for observation. As telescopes continue to advance in size and capability, more and more objects within the nebula are being unveiled," added McCaughrean.

According to Pearson via email, the objects we are observing may be extremely faint, but they appear brightest in the infrared, making it the optimal range for detection. They claim that the JWST, the most advanced infrared telescope ever constructed, is indispensable for these observations, which would be impossible with any other telescope.

Pearson further mentioned that the scheduled observations of the nebula in early 2024 have the potential to offer additional understanding of the atmospheric compositions of the JuMBOs. The researchers also aim to gather more information about these objects, including obtaining accurate measurements of their masses.

Additionally, the investigation of various star-forming regions may uncover the presence of JuMBOs in locations outside of the Orion Nebula. Pearson expressed astonishment, exclaiming, "Where did that originate from?! It is truly astounding, and extensive future examinations and simulations will be necessary in order to elucidate it."
