Astronomers studying the water vapor around a newborn star find that it's chemically similar to ice in solar system comets, a possible source of Earth's oceans.
Water is arguably Earth's most distinctive feature. Much has been made about the search for water elsewhere the universe in the hunt for so-called Goldilocks planets, where temperatures might permit liquid water to exist.

Scientists have presented detailed numerical models of the spectrum of an Earth-like exoplanet carrying bio-signature such as oxygen and ozone molecules along with water molecules.
Since the Nobel prize-winning discovery of the first exoplanet, 51 Pegasi b, in 1995, more than five thousand planets orbiting stars other than the Sun have been discovered through various astronomical methods by using several ground- as well as space-bound telescopes.
How Long is a Day on Each Planet? - WorldAtlas
On Earth , a day lasts 24 hours. The length of a day on our world is determined by the rotational velocity of our planet. When we say a day is 24 hours, this means that it takes 24 hours for the Earth to rotate once about its axis .
A sidereal day is the time it takes for a planet to rotate once about its axis, while a solar day is the time it takes for the sun to return to the same position. While sidereal days generally remain constant, solar days can vary depending on the orbit and axis tilt of a planet.
