The comprehensive study of mineral-rich tiny rocks revolving around the Sun into space could reveal when the solar system actually formed.
Those rocks are known as CAIs (calcium-aluminum-rich inclusions), and researchers have examined such microscopic inclusions inside a strikingly pristine meteorite. And with this study, the researchers have tried to precisely examine the early days at Earth and around it. The study outcomes have concluded that the solids surrounding the Sun adhered together in a short period and evaded from the cloud of hot debris. It is the primary step towards the formation of asteroids and planets.
Cosmochemistry makes use of specific chemical ratios to separate multiple stages of that timeline, such as carbon dating. In this case, it is more complicated. Cosmochemist Maitrayee Bose told Space.com that examining and understanding the chronology of events being occurred during the formation of asteroids and planets would reveal crucial information about the formation of the solar system.
On the contrary, scientists have grabbed some information about the solar system formation by searching for exoplanets. A remarkable example is the observation of a star known as HL Tau; researchers were able to recognize clefts in the debris ring around the star, which indicates that big chunks of debris were adhering.
Likewise, the discovery of the exoplanet k2-18b in 2015 wasn’t an exciting event, but from the past few days, some researchers have been claiming that its atmosphere comprises large amounts of water vapors. The red-dwarf star around which exoplanet k2-18b orbiting is located nearly 110 light-years away from us. Moreover, the distance between the exoplanet and its star reveals that the planet wouldn’t be too hot or too cold.
The exoplanet k2-18b was discovered using the Kepler space telescope. According to the images captured by the Hubble Space Telescope, the planet has a water vapor-rich atmosphere, which is one of the chief characteristics of a planet to be habitable.
