NASA sun data helps new model predict big solar flares

Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.

As it progresses through its natural 11-year cycle, the Sun transitions from periods of high to low activity, and back to high again. The scientists focused on X-class flares, the most powerful kind of these solar fireworks. Compared to smaller flares, big flares like these are relatively infrequent; in the last solar cycle, there were around 50. But they can have big impacts, from disrupting radio communications and power grid operations, to – at their most severe – endangering astronauts in the path of harsh solar radiation. Scientists who work on modeling flares hope that one day their efforts can help mitigate these effects.

Astronomers develop new method for predicting explosive solar flares

We can now predict dangerous solar flares a day before they happen

A new method to predict solar flares could help us to prepare for potential disasters caused by these huge eruptions on the sun.

Predicting solar flares is difficult, because we don’t know exactly how they are triggered. While telescopes can see a flare when it occurs, providing some warning, energetic particles can arrive at Earth in as little as 8 minutes ‘ potentially putting astronauts’ health at risk and damaging satellites before we have time to react.

‘Campfires’ on the Sun: Solar Orbiter captures the ‘closest ever pictures’ of the sun from 47 million miles away

The British-built European Space Agency Solar Orbiter has captured the closest images ever taken of the Sun and it did so while flying between the orbits of Venus and Mercury, according to the UK Space Agency.

The stunning images taken by the Solar Orbiter while 47 million miles away from the surface of our host star include signs of mini solar flares that have been dubbed ‘campfires’ by the scientists behind the probe.

Solar flares are brief eruptions of high-energy radiation from the Sun’s surface and these ‘campfires’ are millions of times smaller than normal flares from the star.’

NASA’s Parker Solar Probe Teams Up With Observatories Around Solar System

At the heart of understanding our space environment is the knowledge that conditions throughout space ‘ from the Sun to the atmospheres of planets to the radiation environment in deep space ‘ are connected.

Studying this connection ‘ a field of science called heliophysics ‘ is a complex task: Researchers track sudden eruptions of material, radiation, and particles against the background of the ubiquitous outflow of solar material.

A confluence of events in early 2020 created a nearly ideal space-based laboratory, combining the alignment of some of humanity’s best observatories ‘ including Parker Solar Probe, during its fourth solar flyby ‘ with a quiet period in the Sun’s activity, when it’s easiest to study those background conditions. These conditions provided a unique opportunity for scientists to study how the Sun influences conditions at points throughout space, with multiple angles of observation and at different distances from the Sun.

Alabama was a big part of a big week for space science and tech

It was a big week for space science and technology, and Alabama is in the middle of a lot of what made news.

To start, NASA closed a chapter in space history Friday at the Marshall Space Flight Center in Huntsville. The space agency put the last piece of the first Space Launch System (SLS) rocket built at Marshall on a barge to Kennedy Space Center in Florida. To mark the milestone, Governor Kay Ivey declared July 17 Artemis Day in Alabama.

The part is called the Launch Vehicle Stage Adapter, and Teledyne Brown Engineering of Huntsville built it to connect the rocket’s core stage and one of its propulsion stages. The propulsion stage was built by Boeing and United Launch Alliance in Decatur. All of it is destined to ride atop the first SLS when it launches in November 2021.

Greetings Earthlings: Those crazy UFOs again! The data presented above may one day be zapped to another dimension. Just thought you should be aware. Hey, buddy, why are all the planets not aligning?
