Our Sun

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.

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.

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.

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

The discovery of tadpole-shaped jets on the Sun adds a new clue to one of the longest-standing mysteries in astrophysics.

On Jan. 19, 2019, just 161 days after its launch from Cape Canaveral Air Force Station in Florida, NASA’s Parker Solar Probe completed its first orbit of the Sun.

Weeks after Parker Solar Probe made the closest-ever approach to a star, the science data from the first solar encounter is just making its way into the hands of the mission's scientists.

On New Year's Day 2019, NASA's New Horizons will fly by a distant Kuiper Belt Object—and open a new chapter in how we define our place in the cosmos.

November 16 marks the premiere of a unique film and musical experience inspired by the Hubble Space Telescope’s famous Deep Field image

Just over a month into its mission, Parker Solar Probe has returned first-light data from each of its four instrument suites. These early observations – while not yet examples of the key science observations Parker Solar Probe will take closer to the Sun – show that each of the instruments is working well.

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission.

Launching from Cape Canaveral Air Force Station in Florida, Parker Solar Probe will make its journey all the way to the Sun’s atmosphere, or corona — closer to the Sun than any spacecraft in history.

The mission will study the Sun closer than any human-made object ever has.
