Parker Solar Probe Endured 28 Coronal Mass Ejections in a 4-Year Period
NASA’s Parker Solar Probe (PSP) embarked on its journey on August 12, 2018, with the ambitious aim of being the first spacecraft to reach out and touch the Sun, offering unprecedented insights into our closest star. Recently, a study submitted to The Astrophysical Journal delves into the wealth of data that PSP gathered on coronal mass ejections (CMEs) over a span of four years. This study has the potential to enhance our understanding of CMEs and their impact on space weather.
The study, led by Dr. Tarik Mohammad Salman, a Postdoctoral Research Fellow at George Mason University, aimed to compile a catalog of CME events observed by PSP from 2018 to 2022 and analyze the evolution of these events as they traveled away from the Sun. One of the primary motivations for the study was the unique opportunity presented by PSP’s direct measurements of CMEs at varying distances from the Sun.
Between October 2018 and August 2022, PSP recorded direct measurements of 32 interplanetary coronal mass ejections (ICMEs) at distances ranging from 0.23 to 0.83 astronomical units (AU). Out of these measurements, 28 were deemed successful, with the study focusing on understanding the changing characteristics of CMEs as they moved further from the Sun.
Key findings from the study highlighted the increasing complexity of the internal magnetic structure of CMEs with radial distance, a slower decrease in magnetic field strength compared to previous studies, and the role of CME expansion in shaping the compression region ahead of it.
While CME research falls under the realm of solar physics, the broader field of space weather is impacted by these phenomena. Space weather, which examines solar activity and its implications on Earth’s environment, can disrupt communication satellites and power grids. This study contributes to the foundation of CME research critical for enhancing space weather predictions and operations.
PSP’s groundbreaking mission includes investigating the solar processes responsible for generating solar wind, studying solar plasma and magnetic field properties, and exploring energy particles emitted by the Sun. By venturing closer to the Sun than any previous spacecraft, PSP’s cutting-edge solar shield allows it to withstand extreme temperatures up to 1,377 degrees Celsius.
Dr. Salman emphasized the pivotal role PSP plays in advancing our understanding of CMEs and space weather. By providing direct measurements of CMEs in their initial propagation phases, PSP aids in improving space weather modeling frameworks and enhancing predictions about CME impacts on Earth.
CMEs, described as massive solar discharges originating from the Sun’s corona, are vital for solar stability yet pose threats to Earth’s technological infrastructure. Understanding CME initiation, propagation, and evolution is crucial for mitigating potential hazards posed by these solar storms. With continued research and advancements, scientists aim to refine their grasp of CME behavior and enhance space weather preparedness.
As researchers delve deeper into the realm of coronal mass ejections, unveiled discoveries and insights await in the coming years. This relentless pursuit of knowledge underscores the importance of scientific exploration and its profound impact on our understanding of the universe.
Indeed, the exploration of CMEs and space weather promises a future rich with revelations, driven by the unyielding spirit of scientific inquiry. Keep looking up, keep doing science!

Is now the right time to invest in gold as prices have cooled?
The price of gold has climbed to record highs recently and has remained strong through much of April. And, that growth continued until the precious metal traded at around $2,390 per ounce on April 19, 2024. But since, growth in the price of the precious metal has cooled, with gold’s price now hovering around $2,300 per ounce.
This lull in gold’s price may represent an investment opportunity.
In general, investing is centered around buying assets when prices are low and selling them when prices are high – generating a profit on the difference between the two. So, considering the declines in gold’s price over the past few days, now may be the time to make your investment. But is buying gold during this lull in prices really a good idea?
Compare your gold investment options among leading brokers now.
Gold prices have cooled. Should you buy in now?
With gold’s price down from recent highs, you may be wondering if now is the right time to buy in. There are several reasons the dip in gold’s price may represent an opportunity to buy. Here are some of the biggest:
Prices may rise again
If looking at a gold price chart shows anything for certain, it shows that changes in the overall growth of the medal come in fits and spurts. Periods of price growth are typically followed by periods of declines and vice versa.
But with inflation rising in recent months – and with gold’s reputation as a safe-haven asset that can hedge against inflation – it only makes sense that the price of the precious metal will eventually start to head up again in the future. While attempting to time that directional change may be tricky, buying the precious metal while the price is down gives you the opportunity to take advantage of any upward movement that may be ahead.
Add gold to your portfolio now before prices have a chance to rise.
You may be able to make a quick profit
Gold isn’t known as an asset in which you can earn a quick return, but in today’s market, that may be the case. Don’t forget that in January, gold was trading at just $2,000 per ounce. And, by mid-April, the commodity’s price had climbed to around $2,400 per ounce. That’s about 20% growth in a matter of months, much of which happened since March 1 – an impressive climb for any investment asset.
Perhaps more importantly, gold’s price growth through the beginning of 2024 shows that the commodity doesn’t have to be a buy and hold style investment that you keep in a safety deposit box or precious metal depository for years to come. There’s also the possibility that the commodity’s price could climb further ahead, making it a compelling way to potentially generate a quick profit.
There are other benefits of investing in gold
There are other benefits of investing in gold that have little to do with the price growth seen thus far in 2024 – or the lull in prices seen over the past couple of days. Those benefits include:
- Inflation protection: Gold has long been considered an inflation hedge, and for good reason. When inflation drives the prices of consumer goods and services up – and the value of the dollar down – gold’s price tends to rise. So, it could be used to maintain the value of your portfolio during inflationary economic conditions. That’s important in today’s economic environment as stubborn inflation continues to weigh on the value of the dollar.
- Portfolio diversification: Gold’s price doesn’t always move in the same pattern that bonds or stocks do. So, mixing a reasonable amount of gold into your portfolio (up to 10% of your portfolio assets) as a diversifier could protect you from losses should one or more of your traditional portfolio assets fall in value. “If you have less than 5% – 10% of your net worth in commodities & FX (forex), you should absolutely consider adding exposure to gold and other precious metals,” says Vijay Marolia, money manager and managing partner at the wealth management firm, Regal Point Capital.
The bottom line
Gold’s price has fallen from recent highs – which may represent an opportunity to tap into growth ahead. However, gold isn’t simply a “buy while it’s low and sell while it’s a high” kind of investment opportunity. The commodity can also protect your portfolio from the stubborn inflation we’ve seen thus far in 2024 while acting as a diversification tool that could increase your risk-adjusted portfolio returns. So, consider adding gold to your portfolio today while it has the potential to grow in value.
