According to the BBC, the James Webb Space Telescope (JWST), the most potent telescope ever built by humans, has discovered Jupiter-sized "planets" that are free-floating in space and not tied to any star. Jupiter Mass Binary Objects, or "JuMBOs," are the names given to these objects. The JWST discovered over 40 pairs of these while surveying the Orion Nebula. Notably, these objects defy both the traditional definition of a planet because they are not in orbit around a parent star and the notion of stars because they are too small to be stars. Astronomers are currently unable to make sense of these enigmatic objects.

Two scenarios for the origin of these enormous objects have been proposed by the European Space Agency (ESA) team. The first is that these objects emerged from parts of the nebula where there was insufficient material density to form stars in their entirety.

The second theory holds that they are planets that were born around stars but were ultimately "kicked out" by gravitational forces. The ejection hypothesis is currently the most popular. Gas physics predicts that things of the mass of Jupiter shouldn't be possible to create independently, and we know that single planets may be expelled from star systems. However, how can you eliminate pairs of these things simultaneously? We don't currently have a solution. It's one for the theorists,'' the senior science adviser for the European Space Agency (Esa) told BBC News.

In 2021-launched and 2022-started Webb telescope has revolutionized knowledge of the early universe while producing breathtaking images of the cosmos. Since it started operating, Webb has produced a flood of previously unheard-of data, showed the existence of the oldest known galaxies, and black holes. The Hubble telescope is nearly 100 times less powerful than Webb.

From February 1961 to October 1968, Webb served as the embryonic space agency's director. He said NASA needed to balance the needs of science with manned spaceflight. The man NASA chose to honor with the name of the Hubble Space Telescope's replacement is most frequently associated with the Apollo lunar program, not with science.

Dimethyl sulfide (DMS) was discovered by NASA's James Webb Space Telescope on exoplanet K2-18b, which may indicate the presence of life. James Webb, NASA's space telescope, may have stumbled onto flimsy evidence pointing to the presence of life on the far-off exoplanet K2-18b.

The James Webb Space Telescope photographed powerful jets erupting from a young star 1,000 lightyears away in September 2023.

According to recent calculations, the visible Universe may include as many as two trillion galaxies. An estimated two trillion galaxies exist. In the known observable Universe, scientists have not sat down and counted every single galaxy they have discovered.
