A computer virus is alive and well on the International Space Station (ISS).
Nasa has confirmed that laptops carried to the ISS in July were infected with a virus known as Gammima.AG.

The worm was first detected on Earth in August 2007 and lurks on infected machines waiting to steal login names for popular online games.
Nasa said […]

The first results from a powerful gamma-ray telescope launched into orbit earlier this summer show it is on track to unlock new secrets of the most energetic explosions in the universe. That was the message from NASA researchers speaking at a teleconference this afternoon to present the findings and to announce the mission’s new name.

A new image from NASA’s Spitzer Space Telescope tells a tale of life and death amidst a rich family history. The striking infrared picture shows a colorful cosmic cloud, called W5, studded with multiple generations of blazing stars.

It also provides dramatic new evidence that massive stars — through their brute winds and radiation — can […]

Astronomers looking through the data from the Sloan Digital Sky Survey, the world’s largest survey of galaxies, have found a new haul of objects closer to home - including one with a potentially exotic origin.

By searching through a survey region known as Stripe 82, a team led by Dr Andrew Becker of the University of […]

Some solar flares may be caused by dark matter particles called axions spewing out from the centre of the Sun, new calculations suggest.

Solar flares are sudden changes in the Sun’s brightness thought to be caused when twisted magnetic fields on […]

The mystery of how young stars can form within the deep gravity of black holes has been solved by a team of astrophysicists at the Universities of St Andrews and Edinburgh.

The team made the discovery after developing computer simulations of giant clouds of gas being sucked into black holes. The new research may help scientists […]
