There is no mention of any alien cube ship near the sun, according to the details of it's latest images by NASA and the European Space Agency.
Solar Orbiter is an international collaboration between the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) to study the sun. It was launched on February 9, 2020, and the European Space Operations Centre (ESOC) in Germany operates it. The first images from Solar Orbiter were captured on July 16, 2020. Details published by the space agencies do not include descriptions of any cube-like structure near the sun.
The campfires shown in the first image set were captured by the Extreme Ultraviolet Imager (EUI) from Solar Orbiter’s first perihelion, the point in its elliptical orbit closest to the sun. David Berghmans, an astrophysicist at the Royal Observatory of Belgium in Brussels, said that campfires are little relatives of the solar flares that we can observe from Earth, million or billion times smaller.
