Sun can emit superflares every 1000 years

The Sun has the potential to emit massive ‘superflares’ every 1000 years, say scientists.

More sun means fewer children and grandchildren

A new study shows that periods of high UV radiation can affect a population over several generations.

Tracking the Earth’s magnetic field in Northern Lights

Physicists are keen on solving the mysteries of the Earth’s magnetic field. Their curiosity has a practical side – when solar storms that create the aurora are bent by the magnetic field, it can affect technologies that modern civilization depends on.

First known Uranian Trojan companion found

A Danish astronomer and his colleagues have discovered a little space rock that circles the sun in the same orbit as Uranus. This is the first time that astronomers observe a so-called ‘Trojan’ asteroid companion for Uranus.

Early Earth was pounded into pieces

Scientists have found evidence of a previously unknown meteor bombardment of Earth some 4.3 to 4.1 billion years ago.

Proof: graphene can convert sunlight to electricity

Graphene has an excellent ability to convert solar radiation into energy. Now we can see how the material works and why it has the potential to massively boost the efficiency of solar cells.

New centre to unravel mystery of solar energy storage

A new research centre has been given five years to develop new techniques for storing solar energy.

Beating the winter blues

The lack of sufficient daylight in northern climes makes many tired and depressed. But don’t worry, researchers have come up with ways to counteract the winter blues.

New model helps scientists understand solar flares

Using a new computer model, researchers can now see how a solar flare arises and develops. An increased understanding of the gigantic explosions on the Sun will over time give us better space weather forecasts.

Giant tornadoes fire up the solar atmosphere

How can the outer regions of the Sun’s atmosphere be upwards of 150 times hotter than the surface? One of the oldest problems of astrophysics has now been partially explained.
