Thank you for reading the news regarding Technology: Scientists detect signs of a planet in the habitable zone and now with the details
Cairo – Samia Sayed – Researchers believe that there is a potentially life-sustaining planet orbiting a dying sun 117 light-years away from Earth, and if their theory is confirmed, it will be the first time that a potentially life-supporting world has been discovered orbiting such This star, called a “white dwarf”.
According to the British newspaper, “Daily Mail”, experts discovered a ring of debris embedded with moon-sized structures near the dying star, indicating a nearby planet in the region known as the “habitable zone”, where water can exist, which is neither too cold nor too cold. Too hot to sustain life.
A white dwarf is a dead star that burns with hydrogen fuel, and almost all stars, including ours, will eventually become a white dwarf as well, so scientists say their results may provide a glimpse into what will happen to our solar system when the sun becomes a white dwarf following billions of years.
The study’s lead author, Professor Guy Farihi of University College London (UCL), said the observation was entirely new to astronomers.
The researcher added: “This is the first time that astronomers have detected any type of planetary object in the habitable zone of a white dwarf.”
In the new study, UCLA researchers measured the light from a white dwarf in the Milky Way known as WD1054-226, using data from ground and space telescopes, and were surprised to find noticeable dips in the light corresponding to 65 evenly spaced clouds of planetary debris. It orbits the star every 25 hours.
The researchers conclude that dimming the star’s light every 23 minutes indicates that the structures have been kept in such a precise arrangement by a nearby planet, and the region will be habitable for at least 2 billion years, including at least 1 billion years in the future.
