Observatories of the Solar System are joining hands with Parker Solar Probe of NASA for the 4th Solar Encounter

 It is crucial to discern the connection between the planets and the solar ecosystem to understand the space environment. This study is known as heliophysics and involves tracing the cataclysmic behavior of the planetary bodies and the debris occupying space.  

The series of space events in 2020 is establishing a perfect environment for space exploits. These events include the development of one of the finest observatories called the Parker Solar Probe and Sun’s activity, which is currently tolerable for scientists and astronauts to study its background. The researchers can probe the effects of the Sun on the solar system from all perspectives.

The Sun is the biggest star with a magnetic field that flows out to the surrounding planetary objects in the form of the solar wind. Various researchers are studying the effect of this magnetic field on the solar system. One of the breakthroughs in this quest is the Parker Solar Probe, an observatory capable of voyaging past 3.8 million miles from the Sun’s visible distance. This observatory is now widely known after carefully observing the Sun in four different encounters.

Initial encounters of the Parker with the Sun shows photos detailing the Sun’s atmosphere. The Parker Solar Probe is the first observatory to come into contact with the Sun’s solar wind before it reaches the Earth. They were able to identify the particular spot on the Sun, giving out this solar wind.

Nour Raouafi, the project scientist for Parker Solar Probe mission, says that they are looking into the region of the Sun that gives out these solar winds. He singles out their intention to understand the dynamics of the source region that lead to the variations in the evolution and the eventual dispersion of the solar winds to the surroundings. Other supporting teams in this probe are space missions and ground-based observatories who plan to help map out the real deal of the solar winds.

During this ubiquitous period, scientists have another task of understanding the ongoing astronomical solar minimum. In this period, the Sun’s solar activity is lowest and abrupt eruptions like solar flares, solar ejections, and momentous energy eruptions are scarce. Therefore, scientists can have a close perception of the Sun’s influence on the solar system.

High Altitude Observatory solar scientists Giuliana de Toma highlights that this is the period for understanding the trails of the solar winds from the Sun and their consequent effects on the planets. He outlines this period as an opportunity for direct research on cosmic radiations.

Sarah Gibson is well-known for co-leading similar expeditions when there occur solar minimums. Scientists are continually pooling their data in such exotic events of the Sun to arrive at a conclusive perception on the formation and distribution of solar winds. 

The data must reach the Whole Heliosphere and Planetary Interactions (WHPI) umbrella for further classification and analysis. This WHPI also gathers data on other space expeditions like lunar and Mars to comprehend the entire solar system and form a trustworthy knowledge base. 

Finally, scientists are confident that they can unlearn more truths hidden in the solar system by taking advantage of the favorable Sun activity.

Speed of the space storms essential to shielding space travelers and the satellites from radiation

Scientists have found out that space weather predictors need to forecast the speed of solar flare-up, as much as their size to guard astronauts and satellites.

The University of Reading Scientists discovered that by computing speed of Coronal Mass Ejections (CME) after hitting Earth, weather analysts could offer more practical early warnings. It could be helpful to operators of vital infrastructure like satellites to know whether they need to take temporary measures or switch off the systems to protect them.

Coronal mass ejections come as a result of vast eruptions of matter from the sun, hurling through space, and alarming the magnetic field of Earth. By the use of solar imagers to calculate the CME speed near the sun, it is likely to forecast the arriving time of the CME to the Earth’s atmosphere. 

Technological systems operators such as satellites that are exposed to the space weather then get to have a chance to take action in a bid to reduce the damage. However, scientists state that such cautions could be more helpful if combined with more complicated information about the harshness of the storm after it hits the Earth.

Professor Mathew Owens, who is a University of Reading a space scientist, stated that Not all the coronal mass ejections activate rigorous radiation. It means that by looking at sun for action, we receive a lot of the false alarms where a deed is taken that is not required. 

While it is advisable to stay safe than sorry, particularly with the astronauts’ health, sometimes the cost of frequently taking unwanted action to guard a satellite network could become more costly compared to the potential space weather dent itself.

Space weather is noted as one of the most significant hazards to the United Kingdom and many other nations because of the likelihood that computers, electricity systems, and communication networks could be interrupted. Billions of dollars are presently being spent on new rockets and systems to enhance forecast and calculate eruptions after their occurrence.

In new research, published on Space Weather, a scientific journal, the researchers summarize a new method of quantifying the value of getting to know the arrival time of CME. They depict that the CME speed on Earth is a helpful additional piece of information that could be of use in reducing the number of the false alarms as well as make forecasts more precious.

The scientists state that heir discovery should assist in guiding future efforts in improving space weather forecast, assisting to guard serious infrastructure and astronauts” health in the forthcoming days.
