![]() ![]() You can track space weather events such as today’s aurora and follow the latest developments, find the latest data, and see a forecast of possible future auroral activity on ESA’s SWE Service Portal. and the triangle is the non-MGM companion to the MGM candidate HD 179958. The mission will give us advance warning of oncoming solar storms and therefore more time to protect spacecraft in orbit, infrastructure on the ground, and explorers now and in the future, unshielded by Earth’s magnetic field and vulnerable to our star’s violent outbursts. Example of recent imaging observations of the solar corona taken with the. ESA’s upcoming Vigil mission will keep an eye on the ‘side’ of the Sun to spot any potentially hazardous solar activity before it rotates into view from Earth. But what could we do if a CME was heading straight for us?Īn early warning is key. A coronagraph is a specialized instrument designed to block out the light of the sun so that researchers can glimpse the burning stars hot, thin, outermost layer, called the corona. Later, in 1895, William Ramsey actually discovered helium on Earth. Fortunately, most of it missed us and no serious impacts on infrastructure on Earth have been reported. For the first time ever, a spacecraft has touched the sun. In the 19th century, some of the spectral lines of sunlight did not match the lines of any substance on Earth, and it was proposed that they came from a new unknown chemical element, named helium (from the Greek helios -Sun). The CME was associated with a solar flare that occurred close to midnight ( UTC) on February 25. The future ESA Vigil mission will provide a first-of-its-kind capability: monitoring the Sun to provide constant, near real-time data on potentially hazardous solar activity.
