NASA scientists are reshaping the basic understanding of a type of wave in space known as a kinetic Alfvén wave.
New research has uncovered a mechanism, similar to one that occurs on Earth, which may allow new insights into forecasting space weather and activity on the sun.
A mysterious flash of X-rays has been discovered by NASA’s Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may be of a variety that scientists have never seen before.
Recent images have revealed the emergence of small-scale magnetic fields in the lower reaches of the corona researchers say may be linked to the onset of a main flare.
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth’s surface may also exist on the sun, according to a new study.
Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists catalogued 17 types of visible particles, with the most recent one being the Higgs boson, creating the ‘Standard Model’. However, they are still struggling to detect the hidden particles, the ones that constitute the dark sector of the Universe.
Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about the Earth’s crust. The result is the release of highest resolution map of this field seen from space to date. This ‘lithospheric magnetic field’ is very weak and therefore difficult to detect and map from space. But with the Swarm satellites it has been possible.
The inner Van Allen belt has less radiation than previously believed, according to a recent study. Observations from NASA’s Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.
Eruptions on the Sun’s surface not only send bursts of energetic particles into the Earth’s atmosphere causing disturbances in our planet’s magnetic field, they can also strangely decrease the number of free electrons over large areas in the polar region of the ionosphere, new research concludes.
Scientists using the All Sky Automated Survey for SuperNovae (ASASSN) have identified a black hole, choking on stardust. Data suggest black holes swallow stellar debris in bursts.
