Extremely active sunspot AR3664 blasted a major X8.7-class solar flare. The sunspot was behind the incredible geomagnetic ...

When sunspots erupt at nearly the same time, it could be something known as "sympathetic solar flares." A double eruption ...

The sun just released a burst of a rare form of helium known as helium-3 ( 3 He). What's peculiar is this lightweight, ...

A solar jet captured by the Solar Orbiter unleashed a mind-blowing 200,000-fold increase in a rare helium isotope, 3He – far ...

A study published in The Astrophysical Journal Letters reveals new insights into the triggering mechanisms of solar ...

The solar array corners are clipped to provide clearance for the high-gain dishes when the Earth is between SDO and the Sun. The four telescopes of AIA are visible on the top with EVE and HMI on ...

In this Solar Dynamics Observatory extreme ultraviolet image, the blue arrow marks a small bright point located at the edge of a coronal hole (outlined in red) that was the source of the phenomenon.

These jets, known as spicules, were captured in an SDO image on April 25, 2010. Combined with the energy from ripples in the magnetic field, they may contain enough energy to power the solar wind ...

NASA's Solar Dynamics Observatory (SDO), which has been monitoring the sun from Earth orbit since 2010, followed up on the event. Using high-resolution imaging, SDO traced the outburst back to a ...
