In a speech at the Oxford University Union, theoretical physicist Stephen Hawking says humanity will not survive another 1,000 years on Earth because of the usual suspects such as climate change, nuclear war and artificial intelligence. Our best chance for survival is to leave earth and find another planet to live on.
Astronomers at NASA have discovered electrons that reside outside the Earth's magnetic field which somehow get super-accelerated once they fall into a turbulent region called the foreshock. High above the surface, Earth’s magnetic field constantly deflects incoming supersonic particles from the sun, but these particles are disturbed in regions just outside the magnetic field and some that get reflected into the foreshock region accelerate almost at the speed of light. And observation from from NASA’s THEMIS (Time History of Events and Macroscale Interactions during Substorms) mission revealed that this turbulent region is responsible for the creation of high-speed electrons.
The GRAPES-3 moun telescope located at the Cosmic Ray Laboratory (CRL) in Ooty recorded a massive burst of galactic cosmic rays about 20 GeV, on 22 June 2015.
A very peculiar system of a planet rotating around three suns has recently been discovered. The planet is known as HD 131399Ab and is located at the constellation of Centaurus.
Stephen Hawking has teamed up with Yuri Milner and Mark Zuckerberg to announce a new project known as Breakthrough Starshot for exploring Alpha Centauri.
Astronauts grow taller in space as the spine elongates due to lack of gravity. Find out other effects of space on humans; including how and why they happen.
Science fiction has conjured up countless pictures of what life could look like if humans could colonize space. But is space colonization even possible?
A huge gas cloud known as the Smith Cloud is on collision course with the Milky Way. If the cloud were visible, it would be 30 times larger than the Moon.
For the first time since 2005, the five brightest planets - Mercury, Venus, Saturn, Mars and Jupiter - will appear together in around an hour or so before sunrise, from about January 20 to February 20.
