Mega Meteorite, 4 Times The Size Of Mount Everest, May Have Sparked Life On Earth: Study
This immense rock slammed into Earth, boiling the oceans and unleashing a record-breaking tsunami.

Phosphorus Grains in Ryugu Samples Offer Insights into Earth’s Early Life Chemistry
Scientists have discovered phosphorus-rich grains in samples from the asteroid Ryugu, brought back by Japan’s Hayabusa2 mission. These grains, thought to have come from the outer Solar System, may have interacted with early Earth’s water, releasing essential nutrients like phosphorus and nitrogen. This interaction could have played a role in th...

Discover LUCA: The 4.2 Billion-Year-Old Ancestor of All Life on Earth
Recent research has revealed that LUCA, the last universal common ancestor of all life, lived around 4.2 billion years ago. This new estimate pushes back the timeline for the origin of life by 300 million years. The study, published in Nature Ecology & Evolution, involved analysis of genes from 700 species of bacteria and archaea, as well as ancien...

All Life On Earth Originates From One Ancestor, Older Than Previously Believed
A new study estimates that LUCA, the Last Universal Common Ancestor of all life on Earth, existed around 4.2 billion years ago, challenging previous timelines for the origin of life.

Groundbreaking New Study Finds Life On Earth Emerged 4.2 Billion Years Ago
Earth itself is approximately 4.5 billion years old, indicating life originated when the planet was still in its infancy.

Canada's Last Chance Lake Has Clues To Origin of Life On Earth: Study
The researchers were drawn towards the Last Chance lake after studying a 1990s unpublished master's thesis that had recorded unusually high levels of phosphate there.

Origins of Life Explored: Study Points To Ancient Hot Springs As Potential Source
This research not only sheds light on Earth's early life, but also raises the tantalizing possibility that similar processes could be occurring in the frozen seas of distant moons.

Origins Of Life On Earth: 4.5 Billion-Year-Old Asteroid Holds Clues
Scientists are hopeful that fragments from a 4.5-billion-year-old space rock will reveal the origins of our existence.

Water Drop Discovered on Ryugu Asteroid Offers Clues to Origins of Life on Earth
A water drop discovered on specks of dust from Ryugu, an asteroid close to Earth, has offered new support for the theory that life on the planet was seeded from outer space. The sample of the asteroid retrieved by the Hayabusa-2 probe has already showed that some of the building blocks of life on Earth, amino acids, may have been formed in space. T...

Traces of Indigenous Gas Found in Meteorite to Shed Light on Moon’s Origin
A recent study has suggested that the Moon may have inherited some noble gases, such as neon and helium, deep from the Earth's mantle. The discovery was made by analysing lunar meteorites found in Antarctica. Upon analysing the glass particles, the team found chemical fingerprints or isotopic signatures of the solar gases in them.

Researchers Identify RNA Precursors in Molecular Clouds Located in the Centre of the Milky Way
An international team of researchers have spotted traces of an organic class of molecules at the centre of the Milky Way which are precursor to molecules essential for life. It is believed that originally life was based on only RNA (ribonucleic acid) on Earth while DNA (deoxyribonucleic acid) and protein enzymes evolved later. RNA is capable of per...

Japanese Space Probe Touches Down On Asteroid To Collect Samples
A Japanese space probe named after a falcon, Hayabusa 2, has touched down on an asteroid more than 300 million kmfrom Earth on a mission to seek clues about the origins of life, Japan's space agency said on Friday.

Japanese Space Probe Reaches Asteroid In Search For Origin Of Life
The probe which traveled for more than three years through deep space will help scientists gain clues about what gave rise to life on Earth from samples taken from Ryugu, which is thought to contain relatively large amounts of organic matter and water.

Scientists Find Potential Missing Link In Origin Of Life On Earth
Scientists, including those of Indian origin, have discovered a compound that may have played a crucial role in the origin of life on Earth.

Fossils Point to Life on Earth 4 Billion Years Ago
The fact that life kick-started not long after Earth formed suggests it could also emerge on watery worlds outside our Solar System at comparable stages of formation.
