For a long, astronomers have been looking for life in the vast universe but for a planet to have water is important.
A study has been published by the GLOBE Institute researchers at the University of Copenhagen, indicating that the planet may have water present during the very formation. As per the study, it is said to be true for Venus, Mars, and Earth.
To support Anders Johansen’s discovery, a Professor of Astronomy at Lund Observatory and his team surveyed how dust particles of ice formed all planets, and millimeter-size carbon revolves around all young stars in the Milky Way. Roughly around 4.5 billion years ago, these same particles accreted into forming a blue planet that was later known as ‘Earth.’
Anders Johansen says, “All our information propose that water was essential for Earth’s structure blocks, directly all along. Also, because – water molecule is oftentimes occurring, there’s a likelihood that it applies to all planets. The decisive point for whether fluid water is available in the distance of the planet from its star.”
The theory suggests that the planets are formed by pebbles forming together, which makes them grow larger, and the theory is named ‘pebble accretion.’
“All planets in the Milky Way are framed by similar structure blocks, implying that planets with a similar measure of water and carbon as Earth – and accordingly potential spots where life might be available – happen as often as possible around different stars in our universe, given the temperature is correct,” he says.
Anders Johansen expressed his thoughts on the next generation of space telescopes.
“The new telescope is powerful. They use spectroscopy, which means that by observing which type of light is being blocked from planets’ orbit around their star, you can see how much water vapor there is. It can tell us something about the number of oceans on that planet”.
