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.
A spacecraft has successfully fired a harpoon into a target orbiting Earth in an operation that could help clean-up the tonnes of space junk threatening telecommunications satellites.
Scientists have found that the magnetic north pole is moving at a speed of about 55 km every year. A hundred years ago, the pole was located near the coast of northern Canada. Now, it is in the middle of the Arctic Ocean.
An international team of scientists found evidence that the rock was launched from Earth by a large impacting asteroid or comet. The impact sent material into space, where it collided with the surface of the Moon 4 bil years ago.
Hidden below the waves off the east coast of Australia, scientists have discovered a 'lost world' of epic volcanic peaks buried under the Tasman Sea, never before seen with human eyes.
Key to the mission is NASA’s Ice, Cloud and land Elevation Satellite-2, which will use the laser instrument to measure - within the width of a pencil - the amount of land ice elevation changes in Antarctica and Greenland.
The international research team found that magnetic field reversals could happen much more rapidly than the thousands of years previously thought to be needed.
