Infant Stars Emit Gas and Dust “Sneezes”
The discovery of baby stars “sneezing” gas and dust into space has opened up a new avenue of research in the field of stellar formation. Scientists have long known that stars are surrounded by protostellar disks, but the mechanisms by which they release gas and dust have remained a mystery. Recent findings suggest that these young stars discharge material in a process akin to a sneeze, expelling magnetic flux into space.
Researchers from Kyushu University in Japan have been using the ALMA radio telescope to study these phenomena in more detail. They have found that the disks around new stars emit jets or plumes of dust and gas, as well as electromagnetic energy. These “sneezes” appear to erode the magnetic flux of young star systems, leading to weaker magnetic fields than previously expected.
The magnetic fields in these protostellar disks play a crucial role in the formation of planets and other celestial bodies. However, the observation of weaker magnetic fields suggests that the flux is being slowly eroded over time. This phenomenon has been observed in various star systems, including MC 27, located 450 light years away.
The team observed “spike-like” structures extending out from the star, containing gas, dust, and magnetic flux. These features, termed “interchange instability”, are believed to be the result of a baby star’s sneeze. Just like a human sneeze expels air and particles from the body, these young stars release gas and dust from their disks.
Further exploration of these phenomena has revealed signs of multiple sneezes occurring in the past, indicating a dynamic and evolving process in star formation. Although similar spikes have been observed in other star systems, more research is needed to fully understand the implications of this discovery.
Overall, this new research sheds light on the complex processes involved in stellar formation and highlights the importance of studying protostellar disks in greater detail. By using cutting-edge technology like the ALMA telescope, scientists are able to uncover fascinating insights into the birth and evolution of stars in our universe.

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.
