Our Sun

They focus on our star, but three of NASA’s Sun-watching spacecraft have also captured unique views of the planets.

NASA and Poland have agreed to cooperate on a NASA heliophysics mission, the Interstellar Mapping and Acceleration Probe (IMAP).

NASA’s Solar Dynamics Observatory, or SDO, has experienced its first lunar transit of the year.

These earthquake-like events release acoustic energy in the form of waves that ripple along the Sun’s surface.

NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth.

Researchers may have found the long-sought “nanoflares” thought to heat the solar corona to its incredible temperatures.

As Chile and Argentina witnessed the total solar eclipse on Dec. 14, 2020, a little tiny speck was flying past the Sun – a recently discovered comet.

NASA has selected two SmallSat missions to share a ride to space in 2025 with the agency’s Interstellar Mapping and Acceleration Probe.

SOHO’s original operating phase was scheduled for two years – and now, through repeated extensions, it is celebrating 25 years in orbit.

New research indicates less intense, but longer-lasting solar storms surprisingly have bigger effects on satellites’ orbits than the shorter, more severe ones.

Measurements from NASA’s New Horizons spacecraft are revising our estimates of one key property of the interstellar medium: how thick it is.

When scientists downlinked data from Parker Solar Probe's sixth orbit, there was a surprise waiting for them: a sungrazing comet.

On Oct. 16, 2020, the Moon photobombed NASA’s Solar Dynamics Observatory’s view of the Sun.

In a new study, scientists looked at sunspots at low resolution to simulate a view of distant stars.

In a paper published in Nature Astronomy, researchers report the first ever clear images of nanojets.

The Sun is stirring from its latest slumber. Sunspots and flares are bubbling from the Sun's surface – signs that a new solar cycle has started.

Surveying sunspots is the most basic of ways we study how solar activity rises and falls over time, and it’s the basis of how we track the solar cycle.

Experts from NASA and NOAA discuss their analysis and predictions for the new solar cycle.

The proposals are for missions to improve our understanding of the Sun and the space environment with which it interacts around Earth.

Astronomers report the discovery of 95 objects known as brown dwarfs, many within a few dozen light-years of our Sun.

Recent observations show that an unusually weak spot in Earth's magnetic field is expanding, weakening, and splitting.

In 2009, NASA launched a sounding rocket to measure helium in the Sun's atmosphere.The results were recently published.

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system.

Scientists have developed a new model that predicted seven out of nine of the Sun’s biggest recent flares.

The first images from ESA/NASA’s Solar Orbiter are now available to the public, including the closest pictures taken of the Sun.
