Mar 11, 2021 Zipping through space at close to the speed of light, Solar Energetic Particles, or SEPs, are one of the main challenges for the future of human spaceflight. Clouds of these tiny solar projectiles can make it to Earth – a 93-million mile journey – in under an hour. They can fry sensitive spacecraft electronics and pose serious risks to human astronauts. But their onset is extraordinarily hard to predict, in part because we still don’t know exactly where on the Sun they come f...

The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George Mason University, Virginia, U.S. These particles...

But its a tricky thing to observe directly, ...

Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observations of the polarization of the Suns ultr...

Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active solar plage region. This is the first time that the magnetic field in the chromosphere has been charted all the way up to its top. This finding brings us closer to understanding how energy is transferred between layers of the Sun.

Ask a Singaporean where they’d like to travel to pre-Covid, chances are you’ll hear Hokkaido, Japan. It’s easy to see why it’s a favourite: everyone loves the weather, the food, and of course, the breathtaking views. While travel might not be the first thing on your mind right now, Hokkaido’s already ready and waiting for visitors to visit their wonderful attractions. The following video shows how Hokkaido is preparing for your return, and what you can look forward to doing when you�...

Oscars 2021: Here Are 5 Qualified Features You May Not Know About Many pundits are calling it for Pixar’s Soul or Cartoon Saloon’s Wolfwalkers,the two most lauded films in the recent round of critics’ awards. A few other big-studio tentpoles are being talked out about as likely nominees with an outside chance of a win: Netflix’s Over the Moon, Pixar’s Onward, Studio Ghibli’s Earwig and the Witch. These predictions are sensible, and this reveals an unfortunate fact about the ani...

Nasa has approved a large contribution to Japan’s Extreme Ultraviolet High-Throughput Spectroscopic Telescope (EUVST) mission. Led by the Japan Aerospace Exploration Agency, the mission involves a solar telescope that will study the way the sun’s atmosphere detaches to become the solar wind. This is a constant sleet of particles that flows through the solar system creating “space weather” that sparks the polar lights on Earth, and disrupts technology. Along with other solar missions, su...
