We have some incredibly powerful telescopes that have given us spectacular views of the cosmos and allowed us to look back to the early days of the universe. These observatories, such as the James Webb Space Telescope (JWST), are amazing feats of engineering that have required billions of dollars and decades of work. But what … Read more
The remarkable aurora in early May this year demonstrated the power that solar storms can emit as radiation, but occasionally the sun does something far more destructive. Known as “solar particle events”, these blasts of protons directly from the surface of the sun can shoot out like a searchlight into space. Records show that around … Read more
The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity indicates the halfway point of solar maximum, the height of solar activity, and the beginning of the shift toward solar minimum. … Read more
Fear passed in front of the sun last week, and a NASA rover saw it fly. The Mars moon Phobos, whose name means “Fear” in ancient Greek, was caught on camera by the NASA Perseverance rover on Feb. 8. The potato-shaped moon was visible in front of the sun from Percy’s current perch in Jezero … Read more
Later this year, the European Space Agency (ESA) will launch the Proba-3 mission into orbit around Earth. This unique project’s twin spacecraft will align with each other to create frequent, artificial eclipses in space, which will give researchers near-unlimited access to studying the sun’s outer atmosphere, or corona, for the first time. An upcoming terrestrial … Read more
The strength of solar storms hitting Earth can vary dramatically over short distances, with places just a few dozen miles apart experiencing very different magnetic disruptions, new research finds. This could mean that some areas are more vulnerable to large solar storms than previously appreciated, study co-author Eija Tanskanen, the director of the Sodankylä Geophysical … Read more
An enormous “solar tornado” the size of 14 Earths stacked on top of each other recently raged on the sun’s surface for three whole days. The enormous plasma twister may be one of the largest ever recorded. The solar tornado emerged near the sun’s north pole on March 15 and continued to grow and shape-shift … Read more
Researchers have finally pinpointed the likely origin of mysterious heartbeat-like signals spat out by the sun during solar flares. The findings could help us learn more about how potentially damaging solar storms are unleashed, a new study shows. Solar radio bursts are streams of electromagnetic radiation — made up mainly of radio waves, as well … Read more
Are aliens using a quirk of the sun’s gravity to transmit information through an interstellar communication network? For the first time ever, astronomers explored this intriguing possibility and scanned for signals coming from hidden nonhuman probes orbiting the sun. So far, the method hasn’t turned up signs of spacefaring aliens, but it represents a promising … Read more
Scientists have captured the first direct evidence of the sun’s magnetic field quickly switching directions, which could help explain the mysterious force that flings particles across our solar system. The researchers observed the phenomenon using the Solar Orbiter probe, which was developed by the European Space Agency (ESA) and is jointly run with NASA. The … Read more
