Solar flares are among the most violent explosions in our solar system, but despite their immense energy -- equivalent to a hundred billion atomic bombs detonating at once -- physicists still haven't been able to answer exactly how these sudden eruptions on the Sun are able to launch particles to Earth, nearly 93 million miles away, in under an hour.

The Sun emitted a strong solar flare on Tuesday, May 10, 2022, peaking at 9:55 a.m. EDT. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Sun Releases Moderate Solar Flare

The Sun emitted a moderate solar flare on May 4, 2022, peaking at 5:00 a.m. ET. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

The Sun emitted a strong solar flare on May 3, 2022, peaking at 9:25 a.m. EDT. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

The Sun emitted a strong solar flare on April 30, 2022, peaking at 9:47 a.m. EDT. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

The Sun emitted two solar flares on April 19, 2022, one moderate peaking at 9:35 p.m. EST and one strong peaking at 11:57 p.m. EST.

Even though Earth's magnetic field shields us from solar wind and space weather--it doesn't always offer complete protection.

Ancient Ice Reveals Mysterious Solar Storm

Through analyzes of ice cores from Greenland and Antarctica, a research team led by Lund University in Sweden has found evidence of an extreme solar storm that occurred about 9,200 years ago.

Mid-Level Flare Erupts From Sun

NASA's Solar Dynamics Observatory captured this image of a solar flare - as seen in the bright flash on the right side of this image of the Sun - on January 20.

Solar Activity And Space Weather

After providing an overview of solar activity as measured by the sunspot number (SSN) and space weather events during solar cycles (SCs) 21-24, we focus on the weak solar activity in SC 24.

The Geospace Dynamics Constellation mission - or GDC - is a team of satellites that will study Earth's upper atmosphere and provide the first direct global measurements of our planet's dynamic and complex interface with the space environment.

While movies show Earth as existing in a calm, pristine corner of the universe, in reality the near-Earth space environment is dangerous and dynamic.

NASA has selected the CubeSat Imaging X-Ray Solar Spectrometer (CubIXSS), led by Southwest Research Institute, to measure the elemental composition of hot, multimillion-degree plasmas in the Sun's corona - its outermost atmosphere.

The Sun Released A Significant Solar Flare

The Sun emitted a significant solar flare peaking at 11:35 a.m. EDT on Oct. 28, 2021. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

A joint NASA-U.S. Naval Research Laboratory experiment dedicated to studying the origins of solar energetic particles -- the Sun's most dangerous form of radiation -- is ready for launch.

Our corner of the universe, the solar system, is nestled inside the Milky Way galaxy, home to more than 100 billion stars.

Solar Storm Stirs Stunning Aurora

After the Sun ejected a violent mass of fast-moving plasma into space on 9 October, ESA waited for the storm to strike.

A Solar Eruption Arrives At Earth

A mass of solar material that erupted from the Sun on Oct. 9, 2021, reached Earth on Oct. 12.

A new meteorological satellite, called Fengyun-3E (FY-3E), is crossing the early morning sky, observing and collecting data about the weather, climate and more.

A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events.
