More important space discoveries are made almost every week. These new discoveries have contributed a lot to our knowledge concerning the formation of the universe in general and our solar system in particular.
A recent discovery, opens another chapter in the history of our solar system with the help of Kepler, the most underrated spacecraft but has proven time and again its usefulness beyond doubt.
In this connection, a group of international astronomers announced a very important new discovery last Tuesday concerning a solar system which is 11.2 billion years old. The universe is estimated to be 13.6 billion years.
Our galaxy, the Milky Way, is only 4.5 billion years old that makes it a baby in the company of the two. We are still drinking milk when they are already eating solid foods by this time.
This is the most ancient star system ever discovered with near-Earth sizes.
By comparison, the five planets are smaller than Earth with the biggest almost the same size as Venus and the smallest approximating that of Mercury.
“We’ve never seen anything like this — it is such an old star and the large number of small planets make it very special,” Huber said in a statement. “It is extraordinary that such an ancient system of terrestrial-sized planets formed when the universe was just starting out, at a fifth its current age.”
The head of the research team, Tiago Campante of the University of Birmingham in England explained that by now knowing near-Earth-size planets formed so long ago, that “could provide scope for the existence of ancient life in the galaxy.
Campante, who is an asteroseismologist also known as stellar seismologist, in order to determine how old and how big this small solar system computed the movement of the star.
The once thought useless Kepler spacecraft is once again making the headlines by performing a spectacular task during the 4-year study. For his reason, the dazzling sun-like star at the middle of this solar system was christened Kepler-444. It’s located in the Lyra constellation which is 2,000 light years away from the Earth.
The team included scientists from Europe, Australia and the United States. Their findings were reported in the latest edition of the Astrophysical Journal.
