Jupiter Mass Binary Objects: Astonishing Discovery of Free-Floating Objects in Orion Nebula

Tuesday - October 3 2023, 08:55 UTC - 1 year ago

The James Webb Space Telescope (JWST) has discovered free-floating objects roughly the size of Jupiter that are surprisingly not bound to any host star. The mystery objects have been named Jupiter Mass Binary Objects (JuMBOs). Scientists postulate that these objects may have formed in areas of the nebula where there wasn't enough material to create complete stars or could have been kicked off into interstellar space as a result of gravitational interactions. The JuMBOs are about 1 million years old and have surface temperatures of approximately 1,832 degrees Fahrenheit (1,000 degrees Celsius). The Orion Nebula was recently photographed by the Webb telescope offering the most remarkable and detailed views to date. At the center of the nebula lies the young Trapezium Cluster of stars, and around the stars are proto-planetary disks formed by gas and dust, possibly leading to the formation of planets.

The James Webb Space Telescope (JWST) has discovered free-floating objects roughly the size of Jupiter that are surprisingly not bound to any host star.

Webb stumbled upon these enigmatic entities during its exploration of the closest star-forming area to Earth, known as the Orion Nebula or M42. This stellar nursery is located 1,350 light-years from Earth in the south of Orion’s belt.

These newly identified mystery objects have been named Jupiter Mass Binary Objects, or JuMBOs. These gaseous presences can be as small as approximately half the mass of Jupiter.

Moreover, these objects are too small to be classified as stars, but they challenge the traditional definition of planets because they do not orbit a central parent star. Thus perplexing scientists.

What makes this discovery particularly fascinating is that these objects seem to be moving in pairs, presenting a puzzling challenge for astronomers currently grappling with the task of explaining them. Webb was able to spot 42 in the Orion Nebula.

Scientists postulate that these objects may have formed in areas of the nebula where there wasn't enough material to create complete stars. Alternatively, they might have formed around stars and then been kicked off into interstellar space as a result of gravitational interactions.

There are currently no models of planetary system formation that have proposed the ejection of binary pairs of planets. Reportedly, "according to existing scientific models, it should not be possible to form single objects so small directly from clouds of dust and gas, let alone in pairs. " .

The JuMBOs are relatively young in astronomical terms, at around 1 million years old, and boast scorching surface temperatures of approximately 1,832 degrees Fahrenheit (1,000 degrees Celsius).

The Orion Nebula has been studied by astronomers for quite some time, but the most recent photographs taken by the Webb telescope offer the most remarkable and detailed views to date.

The recent Webb images were created by compiling 700 individual views captured by the NIRCam instrument over the course of a week.

"The new imaging was obtained with Webb’s near-infrared camera, NIRCam, and has been made into two mosaics, one each from the short and long wavelength channels. These are among the largest Webb mosaics observed to date and given the high resolution and large area, they have been incorporated in ESASky to enable easy exploration of the plethora of interesting astronomical sources contained within them," mentioned the European Space Agency release.

At the central region of this bright nebulae lies the young Trapezium Cluster of stars. Among this cluster, the most massive stars emit powerful ultraviolet radiation, which in turn illuminates the nearby gas and dust.

Numerous stars within this region are encircled by dense proto-planetary disks composed of stellar gas and dust, possibly felicitating the formation of the planets. However, in certain instances, these disks are under threat of being eroded or disrupted due to the extreme radiation and powerful winds blasted by the most massive nearby stars.
