Our Sun

Which way the solar wind blows has new importance as NASA again prepares to send astronauts to the Moon.

As of June 2020, NASA’s Solar Dynamics Observatory – SDO – has now been watching the Sun non-stop for over a full decade.

Researchers have reset the timeline for when stars like our Sun start blasting high-energy radiation into space.

A citizen scientist has spotted a never-before-seen comet in data from SOHO — the 4,000th comet discovery in the spacecraft’s 25-year history.

A confluence of events provided a unique opportunity for scientists to study how the Sun influences conditions throughout space.

Now, for the first time, scientists have used an entire solar cycle of data from NASA’s IBEX spacecraft to study how the heliosphere changes over time.

Images from OSIRIS-REx show rocks on asteroid Bennu appear to be cracking.

NASA’s STEREO-A spacecraft captured these images of comet ATLAS swooping by the Sun.

The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon.

Ice-blue clouds are drifting over the Arctic and that means noctilucent cloud season is here.

Nearly 25 years since its launch, data from SOHO has led to the discovery of well over half of all known comets.

New analysis published in the Astrophysical Journal Letters provides a possible explanation for the origin of switchbacks — sudden reversals in the magnetic field of the solar wind — first observed by Parker Solar Probe during its November 2018 solar flyby.

NASA has selected a new mission to study how the Sun generates and releases giant space weather storms into planetary space.

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.

Solar Orbiter, a new collaborative mission between ESA (European Space Agency) and NASA to study the Sun, launched on Feb. 9.

It will be a dark winter’s night when Solar Orbiter launches from Florida on its journey to the source of all light on Earth, the Sun.

Researchers using Parker Solar Probe data released a new wave of research papers in a special supplement of The Astrophysical Journal

An abridged story of solar scientific history: A genealogy of the advances that led to solar science as we know it today.

NASA is targeting Feb. 9, for the launch of Solar Orbiter, an international collaborative mission between ESA and NASA.

At 4:37 a.m. EST on Jan. 29, 2020, NASA’s Parker Solar Probe broke speed and distance records as it approached the Sun.

A new spacecraft is journeying to the Sun to snap the first pictures of the Sun’s north and south poles.

NASA’s Parker Solar Probe began its fourth solar encounter on Jan. 23, at a distance of about 23.3 million miles from the Sun’s surface.

Spitzer, designed to reveal the far, cold and dusty side of the universe, made discoveries its designers never even imagined, including a previously unseen ring of Saturn.

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.
