A crucial, and often underappreciated, facet of science lies in deciding how to turn the raw numbers of data into useful, understandable information -- often through graphs and images. Such visualization techniques are needed...

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.



Temperatures in the corona — the...

The Solar Dynamics Observatory, or SDO, spacecraft was launched on Feb. 11, 2010, and began collecting science data a few months later. With two imaging instruments – the Atmospheric Imaging Assembly and the Helioseismic and...

NASA's STEREO spacecraft and new data processing techniques have succeeded in tracking space weather events from their origin in the Sun's ultrahot corona to impact with the Earth 96 million miles away, resolving a 40-year...

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new...

How do we know when to stop social distancing and reopen the world? It's complicated, but there are four major goalposts we should meet before we start getting back to normal.

The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on Feb. 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material...

For the first time, using NASA's Solar Terrestrial Relations Observatory, or STEREO, scientists have imaged the edge of the sun and described that transition – from which the solar wind blows. Defining the details of this...

Scientists have just seen a new type of magnetic explosion, known as forced or controlled magnetic reconnection.

At the end of June 2013, NASA will launch its newest mission to watch the sun: the Interface Region Imaging Spectrograph, or IRIS. IRIS will show the lowest levels of the sun's atmosphere, the interface region, in more detail than...

Eclipses set the stage for historic science. NASA is taking advantage of the Aug. 21, 2017 eclipse by funding 11 ground-based scientific studies. As our scientists prepare their experiments for next week, we're looking back to an...

Scientists Nelson Reginald and Natchimuthuk Gopalswamy describe the experiment they will do during the 2016 eclipse in Indonesia.



As the moon slowly covers the face of the sun on the morning of March 9, 2016, in Indonesia,...

Our sun's adolescence was stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

On September 30, 2014, multiple NASA observatories watched what appeared to be the beginnings of a solar eruption. A filament -- a serpentine structure consisting of dense solar material and often associated with solar eruptions...

We're concluding our study of clade gnathifera with a two-part investigation of phylum rotifera. In the first video, we'll focus general characteristics of some of the free-living, non-parasitic rotifers. These creatures have been...

For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there....

Our sun's adolescence was cooler than today, but stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

In February 2020, NASA’s Solar Dynamics Observatory — SDO — is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the Sun, studying how the Sun creates solar activity and...

On April 3, 2009, countries from around the world participated in the '100 Hours of Astronomy' webcast to celebrate the International Year of Astronomy. Produced to support the webcast, this movie highlights the discoveries of the...

PCR tests for Covid-19 are pretty accurate. But they're often very slow and they can be hard to get. Results sometimes aren't available in time to be useful. Faster tests can be less accurate. As we try to reopen schools and businesses...

NASA's Parker Solar Probe is heading to the Sun. Why won't the spacecraft melt?



Thermal Protection System Engineer Betsy Congdon (Johns Hopkins APL) outlines why Parker can take
