That Starry Night Sky? It’s Full of Eclipses An artist’s concept shows the TRAPPIST-1 planets as they might be seen from Earth using an extremely powerful – and fictional – telescope. NASA/JPL-CaltechOur star, the Sun, on occasion joins forces with the Moon to offer us Earthlings a spectacular solar eclipse – like the one that will be visible to parts of the United States, Mexico, and Canada on April 8.
But out there, among the other stars, how often can we see similar eclipses? The answer depends on your point of view. Literally.
On Earth, a total solar eclipse occurs when the Moon blocks the Sun’s disk as seen from part of Earth’s surface. In this case, the “path of totality” will be a strip cutting across the country, from Texas to Maine.
We also can see “eclipses” involving Mercury and Venus, the two planets in our solar system that orbit the Sun more closely than Earth, as they pass between our telescopes and the Sun (though only by using telescopes with protective filters to avoid eye damage). In these rare events, the planets are tiny dots crossing the Sun’s much larger disk.

NASA/Goddard/SDOAnd astronomers can, in a sense, “see” eclipses among other systems of planets orbiting their parent stars. In this case, the eclipse is a tiny drop in starlight as a planet, from our point of view, crosses the face of its star. That crossing, called a transit, can register on sensitive light sensors attached to telescopes on Earth and those in space, such as NASA’s Hubble Space Telescope, James Webb Space Telescope, or TESS (the Transiting Exoplanet Survey Satellite). It’s how the bulk of the more than 5,500 confirmed exoplanets – planets around other stars – have been detected so far, although other methods also are used to detect exoplanets.
“A solar eclipse is a huge transit,” said Allison Youngblood, the deputy project scientist for TESS at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
And both types of “transits” – whether they involve solar eclipses or exoplanets – can yield world-changing science. Solar eclipse observations in 1919 helped prove Einstein’s theory of general relativity, when the bending of a star’s light by the Sun’s gravity caused the star’s apparent position to shift – showing that gravity causes space and time to curve around it.
Exoplanet transits also provide far more than just detections of distant planets, Youngblood said.
“The planet passes in front of the star, and blocks a certain amount of the star’s light,” she said. “The dip [in starlight] tells us about the size of the planet. It gives us a measurement of the radius of the planet.”
Careful measurements of multiple transits also can reveal how long a year is on an exoplanet, and provide insights into its formation and history. Careful measurements of multiple transits also can provide insights into exoplanet formation and history.
And the starlight shining through the exoplanet’s atmosphere during its transit, if measured using an instrument called a spectrograph, can reveal deeper characteristics of the planet itself. The light is split into a rainbow-like spectrum, and slices missing from the spectrum can indicate gases in the planet’s atmosphere that absorbed that “color” – or wavelength.
“Measuring the planet at many wavelengths tells us what chemicals and what molecules are in that planet’s atmosphere,” Youngblood said.
Eclipses are such a handy way to capture information about distant worlds that scientists have learned how to create their own. Instead of waiting for eclipses to occur in nature, they can engineer them right inside their telescopes. Instruments called coronagraphs, first used on Earth to study the Sun’s outer atmosphere (the corona), are now carried aboard several space telescopes. And when NASA’s next flagship space telescope, the Nancy Grace Roman Space Telescope, launches by May 2027, it will demonstrate new coronagraph technologies that have never been flown in space before. Coronagraphs use a system of masks and filters to block the light from a central star, revealing the far fainter light of planets in orbit around it.
Of course, that isn’t quite as easy as it sounds. Whether searching for transits, or for direct images of exoplanets using a coronagraph, astronomers must contend with the overwhelming light from stars – an immense technological challenge.
“An Earth-like transit in front of stars is equivalent to a mosquito walking in front of a headlight,” said David Ciardi, chief scientist at the NASA Exoplanet Science Institute at Caltech. “That’s how little light is blocked.”
We don’t have this problem when viewing solar eclipses – “our very first coronagraphs,” Ciardi says. By pure happenstance, the Moon covers the Sun completely during an eclipse.
“A solar eclipse is like a human walking in front of a headlight,” he said.
We would have no such luck on other planets in our solar system.
Mars’ oddly shaped moons are too small to fully block the Sun during their transits; and while eclipses might be spectacular among the outer planets – for instance, Jupiter and its many moons – they wouldn’t match the total coverage of a solar eclipse.
We happen to be living at a fortunate time for eclipse viewing. Billions of years ago, the Moon was far closer to Earth, and would have appeared to dwarf the Sun during an eclipse. And in about 700 million years, the Moon will be so much farther away that it will no longer be able to make total solar eclipses.
“A solar eclipse is the pinnacle of being lucky,” Tripathi said. “The Moon’s size and distance allow it to completely block out the Sun’s light. We’re at this perfect time and place in the universe to be able to witness such a perfect phenomenon.”

Scientists Use NASA Data to Predict Solar Corona Before Eclipse
4 min read
Scientists Use NASA Data to Predict Solar Corona Before EclipseOur 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 faint, however, so the only way to observe the corona with the naked eye is during a total solar eclipse.
In anticipation of the solar eclipse on April 8, 2024, scientists at Predictive Science are using data from NASA’s Solar Dynamics Observatory (SDO) to predict what our Sun’s crown may look like on that day. What’s more, their model uses the computational efforts of NASA’s Pleiades Supercomputer to update its predictions in near real-time. This means that the model continuously updates its predictions as it ingests data beamed down from SDO, providing information as close to real-time as possible.

The solar corona is our star’s outer atmosphere. It “extends out into interplanetary space as the solar wind,” said Predictive Science president Jon Linker. Driven by heat and magnetic turbulence in the Sun, this wind blows out to the edges of the solar system. “It envelopes the planets,” Linker said, “including Earth.”
As Earth and other planets bathe in coronal outflow, their atmospheres react to the energetic particles and magnetic fields found within the solar wind. This reaction, called space weather, can range from mild to severe, just like terrestrial weather. Extreme space weather events, such as large solar eruptions called coronal mass ejections, can disrupt important communications technology, affect astronauts in orbit, or even harm the electric grids we all rely on.
Modern society depends on a variety of technologies that are susceptible to the extremes of space weather. This graphic shows some of the technology and infrastructure affected by space weather events. NASA’s Goddard Space Flight CenterSpace weather is one of the most tangible effects of the Sun’s dynamic exterior, and creating accurate forecasts is something scientists are striving toward. According to Linker, refining these solar models helps build the foundation for forecasting. “If you’re going to predict the path of a coronal mass ejection, just like for a hurricane, to have this more accurate background is really important,” he said.
SDO and other solar observatories provide detailed insights about the corona, but scientists are still missing some vital information about the forces that drive its activity, which is needed to predict the corona’s appearance with precision. “We don’t have a way of measuring the magnetic field accurately in the corona,” said Emily Mason, a research scientist at Predictive Science. “That’s one of the things that makes this so challenging.”
To build their model, researchers at Predictive Science use measurements of the Sun’s changing magnetic field at the solar surface to drive their model in near real-time. A key to this innovation was creating an automated process that converts raw data from SDO to show how magnetic flux and energy are injected into the corona over time. Adding this dynamic into the model allows the corona to evolve over time, leading to solar eruptions. “We developed a software pipeline that took in the magnetic field maps, picked out all of the areas that should be energized, and then fine-tuned the amount of energy to add to those areas,” Mason said. Building this automatic pipeline was a huge step forward for the team. In past predictions, the model used a static snapshot of the surface magnetic field – not ideal for keeping up with the ever-changing Sun, especially during our current heightened period of solar activity. Similarly, in iterations from 2017 and 2021, Mason explained that a teammate used to “literally hand-draw which areas on the Sun needed to be energized” by analyzing extreme ultraviolet activity in certain regions. Continuously updating the magnetic field is central to all of the changes with this year’s model, and the team has high hopes for the results.
Image Before/AfterThe recurrence of total solar eclipses provides opportunities to test the accuracy of their models against real-life conditions and update them accordingly. “We’ve used the eclipse predictions every time to do something new with the model,” said Cooper Downs, a research scientist at Predictive Science who orchestrated the automated modeling pipeline. “I’m really excited to see over the next two weeks how this prediction keeps improving. I think it will be a really drastic difference from what we used to be able to do.”
Mason shares his enthusiasm. “The eclipse is just such a fantastic chance to go, ‘Look at this! This is what we think it’s gonna look like! Don’t you want to learn more about this?” she said with a grin. “It’s a really exciting opportunity for us to share the things that excite us all year round with everybody else.”
