Emilia Kilpua (born November 18, 1977, in Oulu) is a Finnish space scientist. She is currently Professor of Space Physics at the University of Helsinki. [1]
Kilpua was born and raised in Oulu, northern Finland, where auroras are commonplace in winter. She studied theoretical physics and mathematics at the University of Helsinki, followed by a Master's degree and PhD, with a thesis titled Interplanetary shocks , magnetic clouds and magnetospheric storms , which she completed in 2005. [2] She undertook a postdoctoral research associate post in the Space Sciences Laboratory at UC Berkeley. She moved back to Finland in 2008.
Kilpua's primary research focus is space weather, particularly with an eye to improving forecasting. [3] [4] She has made advances in our understanding of the formation and propagation of coronal mass ejections to Earth, [5] as well as the response of the magnetospheric system, particularly the Earth's radiation belts.

Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline, James Keeler, said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–what they are, rather than where they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
A Birkeland current is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere. In the Earth's magnetosphere, the currents are driven by the solar wind and interplanetary magnetic field and by bulk motions of plasma through the magnetosphere. The strength of the Birkeland currents changes with activity in the magnetosphere. Small scale variations in the upward current sheets accelerate magnetospheric electrons which, when they reach the upper atmosphere, create the Auroras Borealis and Australis.
The Finnish Academy of Science and Letters is a Finnish learned society. It was founded in 1908 and is thus the second oldest academy in Finland. The oldest is the Finnish Society of Sciences and Letters, which was founded in 1838.
Ørsted is an Earth science satellite launched in 1999 to study the Earth's geomagnetic field. It is Denmark's first satellite, named after Hans Christian Ørsted (1777–1851), a Danish physicist and professor at the University of Copenhagen, who discovered electromagnetism in 1820.
Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy, aurorae, planetary ionospheres and magnetospheres, radiation belts, and space weather. It also encompasses the discipline of heliophysics, which studies the solar physics of the Sun, its solar wind, the coronal heating problem, solar energetic particles, and the heliosphere.
Heliophysics is the physics of the Sun and its connection with the Solar System. NASA defines heliophysics as "(1) the comprehensive new term for the science of the Sun - Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like our Sun."
Carl-Gunne Fälthammar was a Swedish electrical engineer and physicist who was Professor Emeritus of electrical engineering at the Royal Institute of Technology in Stockholm, specialising in space and plasma physics. He succeeded Hannes Alfvén as Professor of Plasma Physics in 1975.
Tuorla Observatory is the Department of Astronomy at the University of Turku, southwest Finland. It is the largest astronomical research institute in Finland. Together with the Space Research Laboratory at the Physics Department of the University of Turku, it forms the Väisälä Institute of Space Physics and Astronomy (VISPA).
Sami Khan Solanki is director of the Max Planck Institute for Solar System Research (MPS), director of the Sun-Heliosphere Department of MPS, a scientific member of the Max Planck Society, and a Chair of the International Max Planck Research School on Physical Processes in the Solar System and Beyond at the Universities of Braunschweig and Göttingen.
The Royal Belgian Institute for Space Aeronomy (BIRA-IASB) is a Belgian federal scientific research institute. Created in 1964, its main tasks are research and public service in space aeronomy, which is the physics and chemistry of the atmosphere of the Earth and other planets, and of outer space. The scientists rely on ground-based, balloon-, air- or space-borne instruments and computer models.
Aditya-L1 (/aːd̪it̪jə/) is a coronagraphy spacecraft for studying the solar atmosphere, designed and developed by the Indian Space Research Organisation (ISRO) and various other Indian Space Research Institutes. It is orbiting at about 1.5 million km from Earth in a halo orbit around the Lagrange point 1 (L1) between the Earth and the Sun, where it will study the solar atmosphere, solar magnetic storms, and their impact on the environment around the Earth.
In solar physics and observation, an active region is a temporary feature in the Sun's atmosphere characterized by a strong and complex magnetic field. They are often associated with sunspots and are commonly the source of violent eruptions such as coronal mass ejections and solar flares. The number and location of active regions on the solar disk at any given time is dependent on the solar cycle.
Planetary and Space Science (P&SS), published 15 times per year, is a peer-reviewed scientific journal established in 1959. It publishes original research articles along with short communications (letters). The main topic is Solar System processes which encompasses multiple areas of the natural sciences. Numerical simulations of solar system processes are also conducted at ground-based facilities or on-board space platforms. The editor-in-chief is Maria Cristina De Sanctis. It is published by Elsevier.
John Randolph Winckler was an American experimental physicist notable for his discovery of sprites in 1989 and other discoveries in the fields of solar, magnetospheric, auroral, and atmospheric physics.
Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a planned joint venture mission between the European Space Agency and the Chinese Academy of Sciences. SMILE will image for the first time the magnetosphere of the Sun in soft X-rays and UV during up to 40 hours per orbit, improving our understanding of the dynamic interaction between the solar wind and Earth's magnetosphere. The prime science questions of the SMILE mission are
Helena Aksela is a Finnish physicist and emeritus professor at the University of Oulu. She was the first woman to be appointed a professor of physics in Finland.
Minna Palmroth is a professor in computational space physics at the University of Helsinki; her particular area of interest is magnetospheric physics and solar wind - magnetosphere interactions.
Space climate is the long-term variation in solar activity within the heliosphere, including the solar wind, the Interplanetary magnetic field (IMF), and their effects in the near-Earth environment, including the magnetosphere of Earth and the ionosphere, the upper and lower atmosphere, climate, and other related systems. The scientific study of space climate is an interdisciplinary field of space physics, solar physics, heliophysics, and geophysics. It is thus conceptually related to terrestrial climatology, and its effects on the atmosphere of Earth are considered in climate science.
James Wynne Dungey (1923–2015) was a British space scientist who was pivotal in establishing the field of space weather and made significant contributions to the fundamental understanding of plasma physics.
Hele Irene Savin is a Finnish scientist and inventor, best known for her research in solar cells and is a professor of micro and nanoelectronics at Aalto University. She is publicly known as an inventor and developer of high-efficiency solar cells using nanostructured, so-called black silicon.
