Our Sun

NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before.

Nearly a year and a half into its mission, Parker Solar Probe has returned gigabytes of data on the Sun and its atmosphere.

Scientists have presented new images of the ionosphere, the dynamic region where Earth’s atmosphere meets space.

Four new papers in the journal Nature describe what scientists have learned so far from NASA's Parker Solar Probe.

The Sun is revealing itself in dramatic detail thanks to NASA's Parker Solar Probe.

On Nov. 12, 2019, NASA’s Parker Solar Probe team released scientific data collected during the spacecraft’s first two solar orbits to the general public.

From our perspective on Earth, Mercury looked like a tiny black dot gliding across the Sun’s face.This only happens about 13 times a century.

The Wind mission launched 25 years ago. Wind currently orbits at the first Lagrange point, which allows the spacecraft to face the Sun at all times.

Two robotic spacecraft orbiting the Moon today were initially known as ARTEMIS.

NASA has selected three proposals for concept studies of missions that could help us better understand the dynamic space weather system driven by the Sun that manifests near Earth.

NASA has selected two proposals to demonstrate small satellite technologies to improve science observations in deep space, which could help NASA develop better models to predict space weather events that can affect astronauts and spacecraft.

NASA has selected two proposals for concept studies that could help us better understand the fundamental nature of space and how it changes in response to planetary atmospheres, radiation from the Sun, and interstellar particles.

Since NASA's Parker Solar Probe launched on Aug. 12, 2018, Earth has made a single trip around the Sun — while Parker is into its third orbit around our star.

Earlier this year, Parker Solar Probe downlinked all of the planned science data from its first two passes by the Sun.

NASA has partnered with the Exploratorium in San Francisco to bring live views to people across the world of a total solar eclipse, occurring July 2, over South America.

The forecast for the next solar cycle says it will be the weakest of the last 200 years.

Ten things that result from Einstein’s theories of relativity, first tested 100 years ago this week.

Several NASA robotic landers have captured views of the Sun rising and setting on distant Mars.

El módulo Viking 1 de la NASA mostró por primera vez a los seres humanos cómo se veía una puesta de Sol en Marte, en 1976. Desde entonces, varios otros robots en el Planeta Rojo han enviado a la Tierra una variedad de vistas de amaneceres y atardeceres en Marte.

Auroras at Jupiter's poles are heating the planet's atmosphere to a greater depth than previously thought — a rapid response to the solar wind.

New research documents the first observations of coronal rain in a smaller, previously overlooked kind of magnetic loop on the Sun.

Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA.

Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it’s often in rings.

Every object, planet or person traveling through space has to contend with the Sun's damaging radiation — and the Moon has the scars to prove it.

When a stream of charged particles known as the solar wind careens onto the Moon's surface, they many enrich ingredients that could make water
