In rare events, the sheath of electrons and ions enveloping Venus in a height of 150 to 300 kilometres can expand into space like a tail. This exceptional deformation occurs on the planet’s night side, when the solar wind, the flow of charged particles from the Sun, nearly comes to a stop. Scientists under the lead of the Max Planck Institute for Solar System Research (MPS) were now for the first time able to study such an event in detail. Their analysis is based on data obtained by instruments on board ESA's spacecraft Venus Express. The results may help to understand, whether particles in our solar system can travel from one planet to another – for example from Venus to Earth.

The scientists identified a pulsar that is able to dramatically change the way in which it shines. In just a few seconds, the star can quiet its radio waves while at the same time it makes its X-ray emissions much brighter.

A NASA suborbital telescope has given scientists the first clear evidence of energy transfer from the sun's magnetic field to the solar atmosphere or corona. This process, known as solar braiding, has been theorized by researchers, but remained unobserved until now.

Peering deep into the dim edges of a distorted pinwheel galaxy in the constellation Ursa Major (the Great Bear), astronomers at Case Western Reserve University and their colleagues have discovered a faint dwarf galaxy and another possible young dwarf caught before it had a chance to form any stars.

Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system’s formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.

"Monster" outflows of charged particles from the centre of our Galaxy, stretching more than halfway across the sky, have been detected and mapped with CSIRO's 64-m Parkes radio telescope.
