applications for our open
PhD student position
related to studies of magnetic reconnection in space plasmas.
|26 April 2017:
Cassini's first crossing of the ring plane inside the rings of Saturn, marking
the beginning of the end of the 20 years the NASA spacecraft, with our
Langmuir probe onboard, has spent in space. The final
end of mission is
in September 15.

Ångström laboratory Open House day, we showed ESA's
big (8 metres!) model of the Rosetta space probe and the
with its eerie auroral plasma glow from the University of Leicester.
|7 April 2017:
In his lecture for the docent degree at Uppsala university,
Yuri Khotyaintsev presented the science and techniques behind
our electric field measurements in space plasmas.
We investigate what
goes on in space using instruments we build
ourselves and fly on spacecraft, ground based instruments, computer
simulations and plasma theory. Here are some samples of our research:
For the moment,
we have eight instruments in
various parts of the solar system, and four more to which we have made
a significant contribution.
- Oct 2016: In a paper in Physical
Review Letters, our PhD student
Andreas Johlander have used the Magnetospheric Multiscale (MMS) satellites
to find out the details of shock waves in space. See also our

suggests new ways electrons can be accelerated in a shocked solar wind, based on the Magnet
ospheric Multiscale (MMS) satellite data. The paper was selected as Editor's High
- May 2014: The properties of asymmetric magnetic reconnection, important for storage and release
of magnetic energy in a variety of cosmic contexts, could be explored in detail
with our and other instruments on ESA's Cluster satellites. The results were
published in Physical Review Letters.
- Jul 2013:
Magnetic reconnection can be more efficient in accelerating electrons to
high energy when variable rather than steady, we show in a paper in
- Aug 2012:
Exploring the properties of thin sheets in space, we have for the first time been able
to verify the properties of so called lower hybrid drift waves in space around Earth,
using our instruments on the multi-spacecraft Cluster mission.
The results were published in Physical Review
Letters: see also our press release.
- Jan 2012: Cold plasma previously hidden in the magnetosphere is revealed by our instruments on
the Cluster satellites in a study we publish in Geophysical Research Letters,
also featured in National Geographic Daily News and an AGU news release.
- Jan 2012: We show that dusty plasma around Enceladus affects
Saturn's magnetosphere. See the NASA mission news feature or the editor's highlight in Journal of

when they hit an obstacle, using our instruments on the Cluster satellites
in the Earth's magnetic tail.

known as electron holes dwell at the heart of a
magnetically explosion in space, known as reconnection, we show from
our Cluster data in study in

atmosphere of Mars, we show in Geophysical

turbulence, as shown in a study in Physical Review Letters. See also NASA's and ESA's press releases.

in space. See ESA's press

the Earth far out in space using Cluster. Published in Nature
Geoscience, presented in our press

turbulent plasmas, too. Published in Nature Physics,
presented in an ESA news
- Nov 2006: We reveal the inner structure of a region of space
close to a magnetic reconnection site. Published in Physical Review
- Aug 2005: We discovered Alfvén vortices, a kind of
whirlpools in space, near the boundary of the Earth's magnetosphere.
Published in Nature, presented in
release and in an ESA news feature.

immediately detected cold plasma around Titan and plasma interaction
with ring dust. Published in Science and Geophysical Research

MultiScale mission, launched March 13, 2015, for which we provided sensor
coating and test equipment for the
electric field instruments built by the University of New Hampshire and the Royal
Institute of Technology (KTH). More
info on the SMART instrument suite for MMS at SwRI.
