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.

Scientists from the University of Graz, Kanzelhöhe Observatory, Skoltech, and the World Data Center SILSO at the Royal Observatory of Belgium, have presented the Catalogue of Hemispheric Sunspot Numbers.

Describing The Sun's Electric Field

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star.

Which Way Does The Solar Wind Blow?

The surface of the sun churns with energy and frequently ejects masses of highly-magnetized plasma towards Earth. Sometimes these ejections are strong enough to crash through the magnetosphere -- the natural magnetic shield that protects the Earth -- damaging satellites or electrical grids. Such space weather events can be catastrophic.

Space weather often manifests as substorms, where a beautiful auroral display such as the Northern Lights is accompanied by an electrical current in space which has effects at earth that can interfere with and damage power distribution and electrical systems.

The Aurora's Very High Altitude Booster

A critical ingredient for auroras exists much higher in space than previously thought, according to new research in the journal Scientific Reports.

The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George Mason University, Virginia, USA.

The first observations of a space hurricane have been revealed in Earth's upper atmosphere, confirming their existence and shedding new light on the relationship between planets and space.

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun's flow of high-speed solar wind, detailed in new research published today in The Astrophysical Journal.

A phenomenon first detected in the solar wind may help solve a long-standing mystery about the sun: why the solar atmosphere is millions of degrees hotter than the surface.

In direct contradiction to the official forecast, a team of scientists led by the National Center for Atmospheric Research (NCAR) is predicting that the Sunspot Cycle that started this fall could be one of the strongest since record-keeping began.

At the edge of space, the ever-growing fleet of satellites in low-Earth orbit are locked in a constant, precarious battle with friction.

A Large Sunspot For Thanksgiving

On November 18 scientists from the US National Science Foundation's (NSF's) National Solar Observatory (NSO) predicted the arrival of a large sunspot just in time for Thanksgiving.

One of the first things people want to know before taking a trip is what the weather will be like wherever they are headed.

In 2018, a new aurora-like discovery struck the world. From 2015 to 2016, citizen scientists reported 30 instances of a purple ribbon in the sky, with a green picket fence structure underneath.

New research shows that sunspots and other active regions can change the overall solar emissions.
