For the first time, a NASA spacecraft is flying through the Sun's atmosphere. Nour Raouafi, project scientist for Parker Solar Probe, explains why the Sun's corona is the source of one of the biggest mysteries in all of space science. So, what does it take to build a probe that can touch the Sun—including surviving temperatures of 2,500 degrees Fahrenheit and barreling through sudden eruptions of solar plasma—and live to tell the tale? We'll also go inside the fleet of NASA spacecraft studying the Sun from many angles, including the rescue mission to save a wildly spinning observatory before it became lost in space forever.

Sun Series: Bonus: Dispatches from the Path of Totality | About the Episode

On April 8, 2024, North America experienced its last total solar eclipse until the 2040s. As the Moon’s shadow fell across the U.S., NASA sent Curious Universe producers out into the field across the path of totality to talk to space nerds and eclipse scientists. In this special bonus episode of our Sun Series, we’ll relive the special day together.

Sun Series: Bonus: Dispatches from the Path of Totality

In this episode, Dr. Chelle Gentemann, Open Science Program Scientist for the Office of the Chief Science Data Officer, explains NASA’s initiative to make science more collaborative, accessible, and inclusive. Known as Transform to Open Science, or TOPS, the program encourages increased access to research and data.

Small Steps, Giant Leaps: Episode 129: Accelerating Discoveries with Open Science

For the first time, NASA released a sonification simultaneously with news results associated with two of its telescopes, the Imaging X-ray Polarimetry Explorer (IXPE) and the Chandra X-ray Observatory. The data cover the region near the supermassive black hole at the center of the Milky Way galaxy. The black hole, known as Sagittarius A*, is barely seen in the lower right-hand of the visual image that contains X-ray data from IXPE (red-orange) and Chandra (purple). In the sonification of these data, the cursor begins at Sagittarius A* and moves out as a growing circle toward the center of the image. As it encounters IXPE data, the volume of the notes changes according to the brightness of the X-rays. The brighter the Chandra data, the higher the musical pitch and vice versa. When the cursor travels over a large patch of X-rays both from Chandra and IXPE in the center of the image, a rushing sound is heard. This region is where scientists find a “light echo,” a high-energy relic left behind from an eruption from Sagittarius A* about 200 years ago.

Sagittarius A* Light Echo Sonification

One of the surprising features of black holes is that although light (such as radio, visible, and X-rays) cannot escape from them, surrounding material can produce intense bursts of electromagnetic radiation. As they travel outward, these blasts of light can bounce off clouds of gas and dust in space, similar to how light beams from a car’s headlight will scatter off fog.
A new sonification turns these “light echoes” from the black hole called V404 Cygni into sound. Located about 7,800 light-years from Earth, V404 Cygni is a system that contains a black hole, with a mass between five and 10 times the Sun’s, that is pulling material from a companion star in orbit around it. The material is funneled into a disk that encircles the stellar-mass black hole.
This material periodically generates bursts of radiation, including X-rays. As the X-rays travel outward they encounter clouds of gas and dust in between V404 Cygni and Earth and are scattered at various angles. NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory have imaged the X-ray light echoes around V404 Cygni. Because astronomers know exactly how fast light travels and have determined an accurate distance to this system, they can calculate when these eruptions occurred. This data, plus other information, helps astronomers learn more about the dust clouds, including their composition and distances.

V404 Cygni Sonification

This image shows the region around the Milky Way's central supermassive black hole, known as Sagittarius A* (Sgr A*), in infrared (orange and purple) and X-ray light (blue). The image is scanned from left to right and the data are transformed into sound. The brightness of the objects is represented by the volume, while the vertical positions of the sources in the image are mapped to musical pitches. X-rays are played with a soft synthesizer and the infrared data are heard as bass notes and plucked sounds. The brightest region in the middle of the image (and hence the loudest) is where Sgr A* the black hole, resides. It is within this area that the Event Horizon Telescope was able to peer to obtain the first image of Sgr A* itself.

Ana Roqué de Duprey was born in Puerto Rico in 1853. She started a school in her home at age 13 and wrote a geography textbook for her students, which was later adopted by the Department of Education of Puerto Rico.  Roqué had a passion for astronomy and education, founding several girls-only schools as well as the College of Mayagüez, which later became the Mayagüez Campus of the University of Puerto Rico. Roqué wrote the Botany of the Antilles, the most comprehensive study of flora in the Caribbean at the beginning of the 20th century, and was also instrumental in the fight for the Puerto Rican woman’s right to vote.
