New findings from a team of geochemists at the University of California, Los Angeles (UCLA) indicate that life on our home planet started hundreds of millions of years earlier than previously thought. The discovery was made when looking at ancient zircon crystals, and could change our understanding of early Earth.
A newly-published NASA and Space Telescope Science Institute (STScI) study is asserting that roughly 92 percent of habitable worlds have yet to be created. The research draws on data collected by NASA's Hubble and Kepler space telescopes, with the aim of placing the creation of Earth, and the potential for advanced life in the greater context of the Universe.
NASA has launched a new website allowing the public to view images snapped by its Deep Space Climate Observatory (DSCOVR) satellite. The service will provide multiple shots of stunning Earth imagery seven days a week, mere hours after capture.

The Earth's magnetic field is crucial to life on the planet. It keeps out harmful solar winds, which would strip away our atmosphere and surface water and bombard us with radiation if left unchecked. A new analysis of zircon minerals suggests that the field originated at least 4.2 billion years ago – a hop after the planet formed in the geological timeline, and much earlier than previously thought.
NASA's Deep Space Climate Observatory (DSCOVR) has returned a breathtaking image of planet Earth from a distance of roughly one million miles from the homeworld. The image captures the full disk of our planet showing a stunning sunbathed vista of blue oceans and swirling clouds, with glimpses of the North and Central America land masses.
While there is still much conjecture about the causes of some mass extinctions, it is generally believed that they can occur when a biosphere under long-term stress is subjected to a short-term shock. In 1982, Jack Sepkoski and David M. Raup published a paper identifying five mass extinction events throughout Earth's history. Now a team of researchers claims that we are entering a sixth mass extinction event, which threatens our very existence.
company UrtheCast is celebrating the release of three full-color videos shot from its Ultra HD Iris imaging device, mounted on
the exterior of the International Space Station (ISS). The videos are
but a small taste of the high-quality, near-live streams that the
company is planning to make available to the world with the full
launch of the UrtheCast Earth-viewing platform.
