infrared tools Hubble Space Telescope, shared by NASA and ESA (European Space Agency), managed to capture a strange and complex phenomenon that occurs millions of light years away.
They are called “ghosts” or “ghostly mist” because of their spirit as a concept. They are stars that do not belong to any galaxy or star cluster. That is to say, that they are celestial bodies that are not tied to any gravitational force, for which reason they are considered as “souls in pain” wandering through the immensity of the universe.
A review of Bio Bio Chile says that these points lie between galaxies. They explain that its light is 10,000 times dimmer than the night sky seen from Earth. So, for that they need the infrared from a telescope like Hubble to be able to detect them.
Intergalactic stars are very strange objects in the universe. These celestial bodies are believed to have separated from their home galaxy due to gravitational interactions with other nearby stars or celestial bodies, ie collisions or mergers.
Once on the move, their speed and direction can take them through intergalactic space, where they move alone in the darkness of the universe.
One of the best-known intergalactic stars is the star HE 0437-5439, which was discovered in 2003. This star is located in intergalactic space, at a distance of 200,000 light-years from Earth, and it moves at an incredible speed of over of 1 million kilometers per hour. It is believed to have broken away from its home galaxy about 100 million years ago and has been wandering intergalactic space ever since.
The recent NASA study brought together analyzes of about 10 star clusters located approximately 10 billion light-years away. They focused their gazes on the stars that were in the straits that separate the galaxies to learn about their nature.
Research by space and astronomy agencies indicates that “the fraction of intracluster light in relation to total cluster light remains constant over billions of years,” a concept that reveals that stars never belonged to nearby galaxies.
