The mission takes the closest ever images of the star and in a few years will take a look a the star's poles - the world's first. Solar Orbiter, on the other hand, travelling in the vacuum of space has a perfectly clear view of the star. This is because that light gets absorbed by Earth's atmosphere before it reaches the telescopes' lenses. The new EUI imaging mode, however, allows scientists to peer into regions of the atmosphere that are much closer to the sun's surface than what such rare events and conventional coronagraphs allow.ĮUI images the sun in very high resolution, and although Earth-based telescopes with large mirrors can study the sun's surface in even greater resolution, they can't observe the fascinating high-energy, ultraviolet light that EUI sees. Observers on Earth can naturally see the outermost parts of the sun's atmosphere during total solar eclipses. Solar Orbiter to look at Venus' magnetic field as it swings by the planet The sun crackles in new images from spacecraft preparing for a close flyby That allowed scientists to combine the images and study the links between phenomena observed on the surface and in the atmosphere. Solar Orbiter, for comparison, follows an elliptical orbit that periodically takes the spacecraft within the orbit of the solar system's innermost planet, Mercury.īy coincidence, STEREO happened to be looking at the sun from the same angle as Solar Orbiter was during the experiments with the new EUI imaging mode. In the video sequence obtained through the new imaging mode, scientists combined the Solar Orbiter's EUI view of the sun's atmosphere with an image of the star taken by NASA's STEREO mission, which orbits the sun at a slightly closer distance than Earth does. When the shutter opens only halfway, this thumb obscures the sun's disk, allowing EUI to see with great clarity the faint solar atmosphere. The scientists added a tiny protruding "thumb" to the instruments shutter.
"It is actually a very simple modification to the instrument." "I had the idea to just do it and see if it would work," Auchère said in a European Space Agency (ESA) statement. "There must be some secrets in there that we can now find."ĮUI science team member Frédéric Auchère, an astrophysicist at the Institute of Astrophysics of the Université Paris-Sud in France, described the new imaging mode as a result of "a hack," a last-minute modification devised before the launch of Solar Orbiter in early 2020. "Physics is changing there, the magnetic structures are changing there, and we never really had a good look at it before," David Berghmans, EUI principal investigator and solar physicist at the Royal Observatory of Belgium, said in the statement. Not the best ride in the Kingdom, but certainly a fun one and even suitable for small children.But it is in the part of the light spectrum that is only visible to EUI that scientists can study the most intriguing phenomena that occur at the boundary between the sun's atmosphere and its surface.
The ride is short in duration, but if it is being ignored as it may be close to opening time, give it a try. Also good is if you go to the maximum height, you get good views of the park, especially the Castle. There is a lever in the front that allows you to move the vehicle up and down once the ride gets moving. One adult and two small children should fit just fine. It is a long cylindrical ride with a bench in the center. Warnings: The elevator is small, so if you are at all claustrophic, don’t try to board this ride. Accessibility: Astro Orbiter is wheelchair/ECV accessible, but you must be able to transfer out and get into the ride vehicle. Typical waits range from 25 to 70 minutes. When I went up, I was the only one there!Įmma, the attendant, welcomed me and even wiped off the bench in the nearest "Orbiter". There are no Lightning Lanes for this attraction. The ride has a slow load as you have to take one of two small elevators to the ride platform. I looked around and everyone was holding in line and the poor Astro Orbiter was being ignored. I went for Space Mountain, but unhappily, there was a delay.
