Solar activity News
Three satellites burned up in Earth’s atmosphere just two months after their launch
Solar phenomena such as sunspots and solar flares play a significant role in disrupting satellite operations
The increased solar activity is a mounting concern for satellite operators globally
RAISE images are used to create a data product called a spectrogram, which separates light from the Sun into all its different wavelength components.
The study shows how sunspot records can be used to reconstruct what happened the last time the Earth experienced such a dramatic dip in solar activity more than three centuries ago.
Researchers including those from European Southern Observatory (ESO), produced the images as a demonstration of ALMA’s ability to study solar activity at longer wavelengths of light than are typically available to solar observatories on Earth.
The ultra-high definition video, featuring one entire year of the activity on the sun - from January1, 2015 to January 28, 2016, was released to mark the SDO's sixth year in space.
Researchers in the UK claimed to have created a new model that predicts the solar cycles more accurately than ever before.
