Technology Highlights
The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand.  Much of what we know about these electrons comes from instruments that have fundamental limitations in their ability to sample multiple energies with high time resolution.

Guessing your age might be a popular carnival game, but for astronomers it’s a real challenge to determine the ages of stars. Once a star like our Sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for billions of years. One exception to that rule is the […]

The April 8, 2024, total solar eclipse will produce stunning views across North America. While anyone along the eclipse path with a clear sky will see the spectacular event, the best view might be 50,000 feet in the air, aboard NASA’s WB-57 jet planes. That’s where a trio of NASA-funded teams are sending their scientific […]

Our Sun, like many stars, is adorned with a crown. It’s called a corona (Latin for “crown” or “wreath”) and consists of long, thread-like strands of plasma billowing out from the Sun’s surface. The powerful magnetic field of the Sun defines these strands, causing them to ripple and evolve their structures constantly. The strands are […]

Do you wish you could see a total solar eclipse every day? With a new online tool called Eclipse Watch, you can observe the Sun’s outer atmosphere, or corona, in real time with eclipse-like images from space as we count down to the next total solar eclipse on Earth. The new Helioviewer Eclipse Watch data […]

On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even though it was never designed […]

A total solar eclipse creates stunning celestial views for people within the path of the Moon’s shadow. This astronomical event is a unique opportunity for scientists to study the Sun and its influence on Earth, but it’s also a perfect opportunity to capture unforgettable images. Whether you’re an amateur photographer or a selfie master, try […]
