Image: Our sputtering sun
An active region rotated into view and sputtered with numerous small flares and towering magnetic field lines that stretched out many times the diameter of Earth (May 23-25, 2018).

New network is installed to investigate space weather over South America
A group of Brazilian researchers affiliated with the National Space Research Institute (INPE) is working to install a network comprised of magnetometers (instruments used to measure the intensity of a magnetic field) across ...
Tiangong-1 crash—why it's so hard to predict where space debris will land and what can be done about it
The now defunct Chinese space station Tiangong-1 is en route to crash into Earth – completing its "atmospheric reentry phase". While experts have been aware that this would happen for more than a year, there has been huge ...
Is it acceptable to use a brain scan to read a person's mind?
Using brain scans to see what a person is thinking? There's still a long way to go, but technologies for 'reading' the mind are developing fast. Could the use of such technology create privacy concerns? Giulio Mecacci and ...
Study of starspot lifetimes based on light-curve amplitude and spectral type
sunspots are regions on the sun's photosphere that appear darker than surrounding areas because they are cooler, usually by one or two thousand degrees Celsius. These spots are temporary phenomena caused by magnetic activity ...
Team proposes new space-weather forecasting method
Scientists from Skoltech, the University of Graz and the Royal Observatory of Belgium have developed a method to forecast the strength of the 11-year solar activity cycle. The results of this study may shed light into the ...
Why is massive star formation quenched in galaxy centers?
The current cosmological model to explain the universe, the "Big Bang" model, aims to describe all observable phenomena, including the evolution of galaxies from earliest times to the present day. One of the major problems ...
Solar minimum surprisingly constant
Using more than a half-century of observations, Japanese astronomers have discovered that the microwaves coming from the sun at the minimums of the past five solar cycles have been the same each time, despite large differences ...
Image: Solar Dynamics Observatory spies rare encircling filament
NASA's Solar Dynamics Observatory came across an oddity that the spacecraft has rarely observed before: a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that ...
10 years of the trapped rainbow—the revolution of slow light
A decade on from suggesting light can be dramatically slowed - or even stopped - by new materials, Ortwin Hess reviews the progress and applications.
