Scientists have long searched for planets with characteristics similar to Earth’s, but so far they have not found any other than Mars, which was obviously much easier to detect given that we orbit the same solar system side by side. However, astronomers at the University of Warwick may have found the remains of Earth-like planets. According to the Express, scientists based in the UK have discovered the remains of a planet with a Earth-like shell orbiting the atmosphere of four dwarf stars in deep space.

Scientists say these planets may have existed billions of years ago while the universe was still in its early stages. Scientists have discovered traces of sodium and calcium on the remains of now extinct planets. They also found outer layers containing up to 3,00,000 gigatons of rock debris, including 3,000 gigatons of potassium and 60 gigatons of lithium. The crusts of missing planets are similar to Earth and Mars, suggesting that a planet like ours may have existed or still exists in deep space.

Scientists used data from the European Space Agency’s Gaia telescope to study dwarf stars, which contained elements such as our solar system. The team used spectroscopy to identify similar elements in nearby stars by analyzing the light emitted by each star at different wavelengths. Scientists investigated more than 1,000 dwarf stars before classifying them into four, where Earth-like planets could have existed nearly 10 billion years ago.

A super hot planet found with an Earth-like density
Recently, scientists discovered an unusually super hot Earth-like exoplanet orbiting one of the oldest stars in the Milky Way galaxy. Calling it TOI-561b, astronomers said the exoplanet had an average temperature of over 3,140 Fahrenheit, making it impossible for any life form to survive on it. The high temperature on the planet is because it rotates extremely close to the sun. The researchers also discovered that, although the density of TOI-561b is similar to the density of the earth, it is fifty times higher than our planet.
