The sun in 2018

This montage of 365 images shows the changing activity of our sun through the eyes of ESA's Proba-2 satellite during 2018. The images were taken by the satellite's SWAP camera, which works at extreme ultraviolet wavelengths ...

New sunspots potentially herald increased solar activity

On May 29, 2020, a family of sunspots—dark spots that freckle the face of the sun, representing areas of complex magnetic fields—sported the biggest solar flare since October 2017. Although the sunspots are not yet visible ...

New spider genus named after pop band ABBA

Spiders of the family Araneidae are known for building vertical orbicular webs to catch prey. They can be easily identified by their eye pattern, the abdomen normally overlapping the carapace, and complex genitalia. The family ...

Building robust optical structures made of darkness

Optical devices and materials allow scientists and engineers to harness light for research and real-world applications, like sensing and microscopy. Federico Capasso's group at the Harvard John A. Paulson School of Engineering ...

Solar activity likely to peak next year, new study suggests

Researchers at the Center of Excellence in Space Sciences India at IISER Kolkata have discovered a new relationship between the sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity ...

First video of viruses assembling released

For the first time, researchers have captured images of the formation of individual viruses, offering a real-time view into the kinetics of viral assembly. The research provides new insights into how to fight viruses and ...

Why you shouldn't look at a solar eclipse without eye protection

When a total solar eclipse comes to the Dallas-Fort Worth area on April 8, and the moon starts to cover the sun in the sky, it may feel safe to sneak a peek without eclipse glasses. But experts say that staring at the sun ...

Clouds disappear quickly during a solar eclipse, shows study

Cumulus clouds over land start to disappear almost instantly during a partial solar eclipse. Until recently, satellite measurements during the eclipse resulted in dark spots in the cloud map, but researchers from TU Delft ...
