Magnetic reconnection is a process that converts magnetic energy into bi-directional plasma jets; it is believed to be the dominant process by which solar-wind energy enters the Earth's magnetosphere. This energy is subsequently dissipated by magnetic storms and aurorae. Previous single-spacecraft observations revealed only single jets at the magnetopause—while the existence of a counter-streaming jet was implicitly assumed, no experimental confirmation was available. Here we report in situ two… 
Evidence for an extended reconnection line at the dayside magnetopause
We report in-situ detection by two spacecraft of oppositely directed jets of plasma emanating from a magnetic reconnection site at the Earth’s dayside magnetopause, confirming a key element inherent
Comparison of Magnetospheric Multiscale ion jet signatures with predicted reconnection site locations at the magnetopause
Magnetic reconnection at the Earth's magnetopause is the primary process by which solar wind plasma and energy gains access to the magnetosphere. One indication that magnetic reconnection is
Continuous magnetic reconnection at Earth's magnetopause
It is shown that reconnection at Earth's high-latitude magnetopause is driven directly by the solar wind, and can be continuous and even quasi-steady over an extended period of time.
In situ detection of collisionless reconnection in the Earth's magnetotail
The serendipitous encounter of the Wind spacecraft with an active reconnection diffusion region is reported, in which are detected key processes predicted by models of collisionless reconnection in the magnetotail.
Accelerated flows at Jupiter's magnetopause: Evidence for magnetic reconnection along the dawn flank
We report on plasma and magnetic field observations from Juno's Jovian Auroral Distributions Experiment and Magnetic Field Investigation at 18 magnetopause crossings when the spacecraft was located
Double-reconnected magnetic structures driven by Kelvin-Helmholtz vortices at the Earth's magnetosphere
In an almost collisionless magnetohydrodynamic plasma in a relatively strong magnetic field, stresses can be conveyed far from the region where they are exerted, e.g., through the propagation of
Magnetic reconnection at the dayside magnetopause: Advances with MMS
Magnetic reconnection is known to be an important process for coupling solar wind mass and momentum into the Earth's magnetosphere. Reconnection is initiated in an electron‐scale
Modification of the Hall physics in magnetic reconnection due to cold ions at the Earth's magnetopause
Magnetic reconnection is a process permitting mass and energy exchange across plasma boundaries and converting magnetic energy into particle kinetic energy. Strong electric fields and currents due to
Evidence for interplanetary magnetic field By controlled large‐scale reconnection at the dayside magnetopause
We report evidence of a long-lasting reconnection event during which the accelerated plasma flow direction changes in response to an interplanetary magnetic field (IMF) By reversal, indicating a
The Location of Magnetic Reconnection at Earth’s Magnetopause
Improved methodology using the time-of-flight effect of precipitating ions in the cusp regions and the cutoff velocity of the precipitating and mirroring ion populations was used to pinpoint magnetopause reconnection locations for a wide range of solar wind conditions.


Evidence for magnetic field reconnection at the Earth's magnetopause
Eleven passes of the ISEE satellites through the frontside terrestrial magnetopause (local time 0900–1700; GSM latitude 2–43°N) have been identified, where the plasma velocity in the magnetopause and
Plasma acceleration at the Earth's magnetopause: evidence for reconnection
A characteristic of magnetic field reconnection is the acceleration of plasma as it flows across a rotational discontinuity. At the Earth's magnetopause this effect has only been observed recently
