NASA Astronaut Captures Stunning Green Aurora Behind Russian Soyuz Spacecraft Docked at ISS
NASA astronaut Matthew Dominick, aboard the International Space Station, recently captured an extraordinary image of the Russian Soyuz spacecraft with a vibrant green aurora in the background. The photograph, taken during Expedition 71 in 2024, showcases the breathtaking beauty of space and the fascinating interplay between solar activity and Earth...

How Long Will Oxygen-Rich Atmosphere Sustain On Earth? Study Says...
The shift will take Earth back to something like the state it was in before what's known as the Great Oxidation Event (GOE) around 2.4 billion years ago, said the study.

NASA's Perseverance Rover Finds Diverse Set Of Organic Molecules On Mars
Organic molecules are the key building blocks of life on Earth that are made primarily of carbon and hydrogen and often other elements like oxygen, nitrogen, phosphorus, and sulphur.

Where Did Earth's Oxygen Come From? Scientists Hint At An Unexpected Source
The amount of oxygen in the Earth's atmosphere makes it a habitable planet. 21% of the atmosphere consists of this life-giving element. But in the deep past - as far back as the Neoarchean era 2.8-2.5 billion years ago - this oxygen was almost absent

Ancient Oxygen Source Detected in Earth’s Crust; May Have Influenced Evolution of Life, Researchers Say
Researchers have discovered a mechanism through which hydrogen peroxide can be generated from rocks under the Earth's surface during the movement of geological faults. The oxygen source could have influenced the early evolution of life on Earth when photosynthesis wasn't there, according to the researchers.

World’s Oldest Wildfires Date Back 430 Million Years, Shed Light on Earth’s Flora and Oxygen Levels Then
Scientists have discovered the world's oldest wildfires thanks to 430-million-year-old charcoal deposits found in Wales and Poland. They reveal a lot about what life was like on Earth during the Silurian period.

Moon’s Top Layer Can Provide Enough Oxygen for 8 Billion People for 100,000 Years
The Moon's layer of rocks, called regolith, contains enough oxygen to sustain human life. If a new study is to be believed, the Moon's surface has enough oxygen to keep 8 billion, or 800 crore people alive for around 1,00,000 years.

NASA's OSIRIS-REx Probe Finds Signs of Water on Asteroid Bennu
OSIRIS-REx, which flew last week within a scant 19km of the asteroid Bennu some 2.25 million kilometres from Earth, found traces of hydrogen and oxygen molecules.

Mars Likely To Have Enough Oxygen To Support Life, Finds Study
Salty water just below the surface of Mars could hold enough oxygen to support the kind of microbial life that emerged and flourished on Earth billions of years ago, researchers reported Monday.

Protective Magnetic Field Helped Life Begin On Earth
Not just water and oxygen, life thrived on early Earth thanks to another necessary ingredient: the presence of a protective magnetic field.

Oxygen Was Present On Earth Far Earlier Than Thought: Study
Small levels of atmospheric oxygen had already developed on Earth about 3.8 billion years ago, much earlier than previously thought, a new study has found. Reconstructing the emergence and evolution of life on our planet is tightly linked to the questions as to when and to what extent Earth's atmosphere became oxygenated.

NASA's Mars Rover Spots Loads Of Silica, Bolsters Water Presence
NASA's Mars rover Curiosity has found mysterious rocks rich in silica - a rock-forming chemical combining the elements silicon and oxygen and commonly seen on Earth as quartz.

Global Warming Could Cause Fall in Oxygen on Earth: Study
Earth's oxygen could dramatically fall due to change in ocean temperature of just several degrees, which may likely result in the mass mortality of animals and humans, a new study has claimed.

A Whiff From Blue-Green Algae Gave Oxygen to Earth
Oxygen on Earth emerged in whiffs from a kind of blue-green algae in shallow oceans around 2.5 billion years ago, helping the origin of life with enough oxygen around to inhale, shows significant research from Canadian and US scientists.

Atmospheric Oxygen Levels Influenced Past Climate: Study
Changing oxygen levels in Earth's atmosphere could have significantly altered global climate throughout the planet's history, a US study said on Thursday.
