  1. Humankind has studied the Sun for millennia. Look through highlights from the history of solar science, from ancient records of solar eclipses & sunspots to the upcoming launch of , which will provide the first-ever images of the Sun's poles:

    made its 4th close approach to the Sun early this morning and set new records in the process! Parker flew about 11.6 million miles from the Sun and achieved a top speed of more than 244,000 mph, breaking records it set in 2018:

    Our Interstellar Mapping and Acceleration Probe is one step closer to launch! The IMAP mission will study the boundaries of the heliosphere, where material from the Sun meets interstellar space. IMAP is slated to launch in 2024:

    , an & collaborative mission, launches in February! This spacecraft will study the Sun from a unique perspective: its tilted orbit carries it out of the plane of the planets so it can take the first-ever pictures of the Sun’s poles.

    Magnetic storms near Earth can generate dazzling auroras ⬇️ and also release high-energy particles hazardous to spacecraft & astronauts. Our THEMIS mission saw one such event much closer to Earth than previously thought possible. More from :

    A planet’s magnetic field plays a big role in how much the host star affects the planet. Here on Earth, we have a robust magnetic field that shields us from solar activity, but not every world is so lucky. More factors to consider in the :

    What makes an exoplanet habitable? It’s not just about the planet itself — the activity of its star matters, too! ⭐️

    Since we can’t travel to worlds beyond our solar system, scientists use what we know about Earth to predict the characteristics of exoplanets — including whether they might be able to support life.

    Spitzer’s infrared observations also gave us a unique view of Comet ISON, which made its dramatic final journey around the Sun in 2013 — also observed by many of our Sun-watching satellites!

    After 16 years, we’re saying farewell to . This infrared observatory shed new light on galaxies, stars and worlds — including our own Sun. Spitzer’s data showed scientists that our star was a relatively late bloomer in the Milky Way:

    The Sun is just right for Earth, but another type of star may be "Goldilocks" when it comes to searching for life on other worlds — not too hot, not too cool, and not too violent to host habitable planets. More on this research:

    In the upper reaches of the atmosphere, at the boundary between Earth and space, particles and gases and energy do an intricate and colorful dance that varies daily. Our new mission is watching that dance up close:
