New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to…
Active regions on the sun combined to look something like a jack-o-lantern’s face on October 8, 2014. The active regions appear brighter because those are…
On October 16, 2020, the Moon photobombed NASA’s Solar Dynamics Observatory’s view of the Sun. This apparent crossing in space, called a lunar transit, lasted…
NASA’s extensive fleet of spacecraft allows scientists to study the Sun extremely close-up – one of the agency’s spacecraft is even on its way to…
Late on August 16, 2020, the Sun released a burst of light and energy known as a solar flare. This B1-class solar flare – the…
Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from…
At the heart of understanding our space environment is the knowledge that conditions throughout space — from the Sun to the atmospheres of planets to…
As of June 2020, NASA’s Solar Dynamics Observatory – SDO – has now been watching the Sun non-stop for over a full decade. From its…
In February 2020, NASA’s Solar Dynamics Observatory — SDO — is celebrating its 10th year in space. Over the past decade the spacecraft has kept…
NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the…
Starting around approximately 1200 – 1808 UTC (7:00 am – 1:38 pm ET) November 11, 2019, NASA’s Solar Dynamics Observatory watched as Mercury moved across…
NASA’s Solar Dynamics Observatory views our Sun in ten different wavelengths because each wavelength reveals different solar features. This September 21, 2018, view of the Sun uses…
On September 9, 2018, NASA’s Solar Dynamics Observatory, SDO, saw two lunar transits as the Moon passed in front of the Sun. A transit happens…
Without special instrumentation, the Sun looks calm and inert. But beneath that placid façade are countless miniature explosions called nanoflares. These small but intense eruptions…
NASA’s Solar Dynamics Observatory (SDO) scientists used their computer models to generate a view of the Sun’s magnetic field on August 10, 2018. The bright…
Each and every day NASA’s Solar Dynamics Observatory (SDO) observes our Sun and relays observational data to scientists on Earth in an effort to understand…
From March 20-23, 2018, NASA’s Solar Dynamics Observatory captured three sequences of our Sun in three different extreme ultraviolet wavelengths. The resulting images illustrate how…
