Image: Instant space selfies

How many times have you taken a selfie and posted it instantly to your favourite social media channel? The Mercury Transfer Module of the BepiColombo spacecraft, currently en route to Mercury, is equipped with three 'selfie-cams' ...

Ultra-hot gas around remnants of sun-like stars

Solving a decades-old mystery, an international team of astronomers have discovered an extremely hot magnetosphere around a white dwarf, a remnant of a star like our Sun. The work was led by Dr. Nicole Reindl, Research Fellow ...

Image: BepiColombo magnetometer boom deployed

The 2.5 m long boom carrying the magnetometer sensors onboard ESA's BepiColombo Mercury Planetary Orbiter (MPO) has been successfully deployed. The sensors are now prepared to measure the magnetic field on the way to Mercury.

BepiColombo: Two orbiters head to mercury

Known since antiquity, Mercury has not yet delivered all its secrets. The international mission BepiColombo, scheduled to launch in the coming days, will study the planet's surface and compare its magnetic field with that ...

SwRI's Strofio will measure Mercury's 'exosphere'

The European Space Agency's BepiColombo spacecraft will launch towards Mercury carrying a unique payload designed and built at Southwest Research Institute: an instrument called Strofio, which will study Mercury's tenuous ...

BepiColombo monitoring camera test image

Magnetosphere

A magnetosphere is formed when a stream of charged particles, such as the solar wind, interacts with and is deflected by the intrinsic magnetic field of a planet or similar body. Earth is surrounded by a magnetosphere, as are the other planets with intrinsic magnetic fields: Mercury, Jupiter, Saturn, Uranus, and Neptune. Jupiter's moon Ganymede has a small magnetosphere — but it is situated entirely within the magnetosphere of Jupiter, leading to complex interactions. The ionospheres of weakly magnetized planets such as Venus and Mars set up currents that partially deflect the solar wind flow, but do not have magnetospheres, per se.
