The ESA/NASA Solar Orbiter mission, launched in February 2020, will explore the Sun and heliosphere from close up and from out of the ecliptic plane. It aims to address the overarching questions of how the Sun creates and controls the heliosphere, and why solar activity changes with time. Among the instruments that Solar Orbiter carries is the Polarimetric and Helioseismic Imager (SO/PHI), which is the first magnetograph to leave the Sun-Earth line and to observe the Sun from different directions. Solar Orbiter is still in its cruise phase and SO/PHI is still undergoing various tests, improving its calibration procedures, etc. Nonetheless, already a few glimpses of SO/PHI’s capabilities have become apparent, including the excellent quality of the data. The promise for the science that can be done with SO/PHI data in the future is immense, both with standalone observations by SO/PHI and with SO/PHI data combined with observations made by other Solar Orbiter instruments, or with data

Warum Harvard-Astrophysiker Avi Loeb Oumuamua für Alien-Technologie hält op-marburg.de - get the latest breaking news, showbiz & celebrity photos, sport news & rumours, viral videos and top stories from op-marburg.de Daily Mail and Mail on Sunday newspapers.
Harvard University astronomer Abraham Loeb claims that a discarded alien machine visited the solar system but was mistaken as a natural object because of “groupthink.”
In his forthcoming book, “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth,” Loeb wrote about the solar system’s first known interstellar visitor, ‘Oumuamua. He posited that ‘Oumuamua is really technological trash thrown away by an intelligent alien civilization based on its cigar or disk shape, shininess and behavior, which he noted are unlike anything ever seen in the solar system before.
However, Loeb said that his ideas are not taken seriously by the scientific community because everyone refuses to wrest free from the mainstream view that the object was just a space rock.
Harvard astrophysicist Avi Loeb has reignited a debate about whether alien life can explain an object that visited the solar system in 2017 in a scathing new book.
