Behold, the closest-ever photo of a coronal streamer

It was captured by the Parker Solar Probe, which is currently studying the star.

NASA
  • NASA's Parker Solar Probe is currently traveling closer to the sun than any other spacecraft before it.
  • The probe is recording data on the star to help scientists learn more about the star and its volatile nature.
  • Also this week, NASA released the first images of its Mars InSight lander taken from space.

NASA's Parker Solar Probe has come closer to the sun than any human spacecraft before it, managing to enter the star's atmosphere to record data for the ambitious mission.

On November 8, the probe soared within about 15 million miles of the sun's surface. To illustrate how close that is, NASA researchers wrote: "If Earth was at one end of a yard-stick and the Sun on the other, Parker Solar Probe will make it to within four inches of the solar surface."

During the encounter, the probe's wide-field imager snapped the closest-ever photo of the sun emitting solar material, in an event known as a coronal streamer.

These events usually occur over regions undergoing increased solar activity, and this one appeared over the east limb of the sun and includes at least two visible rays. Jupiter, the bright spot toward the center of the photo, is also visible in the background.

The photo was shared at a meeting of the American Geophysical Union earlier this week.

"Heliophysicists have been waiting more than 60 years for a mission like this to be possible," said Nicola Fox, director of the Heliophysics Division at NASA Headquarters in Washington. Heliophysics is the study of the Sun and how it affects space near Earth, around other worlds and throughout the solar system. "The solar mysteries we want to solve are waiting in the corona."

What the Parker probe mission hopes to accomplish

The Parker Solar Probe is on an exploratory mission that could yield surprising findings for scientists, namely because no one's quite sure what exactly happens when a spacecraft gets so close to the sun. NASA hopes the mission will address three key questions:

"First: How is the sun's outer atmosphere, the corona, heated to temperatures about 300 times higher than the visible surface below?" NASA wrote in a blog post. "Second — how is the solar wind accelerated so quickly to the high speeds we observe? And finally, how do some of the sun's most energetic particles rocket away from the sun at more than half the speed of light?"

To answer these questions, the Parker probe must match the speed of the sun's rotation so it can hover over areas of interest, meaning it must fly faster than 213,000 miles per hour. Learning more about the star is important, given its tremendous influence on our planet and those in our solar system. NASA writes:

"The solar wind, its outflow of material, fills up the inner part of our solar system, creating a bubble that envelops the planets and extends far past the orbit of Neptune. Embedded in its energized particles and solar material, the solar wind carries with it the Sun's magnetic field. Additional one-off eruptions of solar material called coronal mass ejections also carry this solar magnetic field — and in both cases, this magnetized material can interact with Earth's natural magnetic field and cause geomagnetic storms. Such storms can trigger the aurora or even power outages, and other types of solar activity can cause communications problems, disrupt satellite electronics and even endanger astronauts — especially beyond the protective bubble of Earth's magnetic field."

NASA also releases first images of Mars InSight lander taken from space

This week, NASA published the first images taken of its Mars InSight lander, which touched down on the red planet in November and is designed to help scientists learn more about the formation of rocky planets. The images were taken from HiRISE, a camera onboard NASA's Mars Reconnaissance Orbiter (MRO).

Remote learning vs. online instruction: How COVID-19 woke America up to the difference

Educators and administrators must build new supports for faculty and student success in a world where the classroom might become virtual in the blink of an eye.

  • If you or someone you know is attending school remotely, you are more than likely learning through emergency remote instruction, which is not the same as online learning, write Rich DeMillo and Steve Harmon.
  • Education institutions must properly define and understand the difference between a course that is designed from inception to be taught in an online format and a course that has been rapidly converted to be offered to remote students.
  • In a future involving more online instruction than any of us ever imagined, it will be crucial to meticulously design factors like learner navigation, interactive recordings, feedback loops, exams and office hours in order to maximize learning potential within the virtual environment.
