Recently Australian researchers found the first ever evidence of a plutonium radioactive isotope in the Earth's crust that originally came from outer space, namely a supernova.
Sentinel-6 satellite lifted off on a SpaceX Falcon 9 rocket on Nov 21. Its mission now is to measure and chart the rise of the sea level more precisely than ever before.
A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed - instead of far-reaching comets or asteroids delivering such water.
Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth.
The South Atlantic Anomaly is a vast expanse of reduced magnetic intensity in Earth's magnetic field, extending all the way from South America to southwest Africa.
A robotic servicing spacecraft has hooked up with an aging satellite over the Pacific Ocean. It accomplished the first link-up between two commercial satellites in space, and the first docking with a satellite that was never designed to receive a visitor.
A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.
We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.
The satellite called Icon, or Ionospheric Connection Explorer, will transmit data intended to help scientists understand the physical processes at work where Earth's atmosphere interacts with near-Earth space.
Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn caused diversification.
New research by a team of UK scientists has located the site of the massive impact that took place in Scotland 1.2 billion years ago. Roughly one billion years ago, Earth experienced a higher rate of meteorite impact than it does today.
There are at least 34,000 pieces of large debris in Low Earth Orbit. Now spanish scientists has come up with a simple but elegant idea: equip future satellites with a tether system so they can de-orbit themselves at the end of their lives.
A mysterious large mass of material has been discovered beneath the largest crater in our solar system - the Moon's South Pole - Aitken basin and may contain metal from the asteroid that crashed into the Moon and formed the crater.
The European Very Large Telescope participated in test coordinated by the International Asteroid Warning Network, successfully targeting, tracking and imaging a double asteroid as it flew within 5.2 million km of Earth on 25 May.
An extreme form of solar storm, known as a solar proton event (SPE) struck our planet in 660 BCE. If an event of such magnitude were to happen today, it would likely wreak havoc on our technological infrastructure.
