More Water Than Earth’s Oceans Found in Planet-Forming Disk
A groundbreaking discovery has been made by astronomers, who have identified a significant amount of water vapor in the protoplanetary disk surrounding a young star. The quantity of water present in the dust of this disk is three times more than the combined volume of water in all of Earth’s oceans. What makes this discovery even more remarkable is that the water is densely concentrated in the inner region of the disk where rocky planets tend to form.
The implications of this finding are profound, as water is a fundamental ingredient for life. The discovery of such abundant water in a protoplanetary disk that is conducive to planet formation is a fascinating revelation. The significance of this discovery is detailed in a new paper published in Nature Astronomy titled “Resolved ALMA observations of water in the inner astronomical units of the HL Tau disk,” with leading author Stefano Facchini, an astronomer at the Università degli Studi di Milano, Milano, Italy.
Facchini expressed his astonishment at the discovery, stating, “I had never imagined that we could capture an image of oceans of water vapor in the same region where a planet is likely forming.” This revelation was made possible by observing the young star HL Tau, which is approximately 450 light-years away and is suspected to be less than 100,000 years old, making it a prime target for studying planet formation. The Atacama Large Millimeter/submillimeter Array (ALMA) played a crucial role in capturing high-resolution images of HL Tau and its disk, revealing distinct rings that indicate the formation of young planets.
The presence of substantial water vapor in the protoplanetary disk of HL Tau has captivated the scientific community, further enhancing its appeal for extensive observation. The paper’s authors assert that the observations open avenues to studying the water content in the inner regions of similar disks. The precise analysis conducted by ALMA revealed a lower limit estimate of 3.7 Earth oceans worth of water vapor within the inner 17 astronomical units of the HL Tau system.
As planets form within a protoplanetary disk, they create clearings in the dust, indicating their presence. ALMA’s detailed observations have provided crucial insights into this process. The researchers underscore the uniqueness of ALMA in its ability to detect water in such disks. The facility’s capability to spatially resolve water vapor distribution within the disk has been instrumental in shedding light on the planet formation process.
The researchers examined different frequencies of water molecules using ALMA, elucidating the intricate relationship between water and dust in planet-forming disks. The observations revealed water vapor in regions where gaps suggest the formation of planets, indicating that the water is likely being incorporated into the planetary bodies. By examining water as it emerges from dust particles, astronomers gained valuable insights into the process of planet formation.
The discoveries made through this study carry significant implications for understanding the mechanisms governing the development of planetary systems. The research team emphasizes the pivotal role of ALMA in advancing our understanding of protoplanetary disks. While ALMA has provided invaluable insights, future telescopes such as the Extremely Large Telescope with the METIS instrument are poised to offer even more detailed perspectives on planet formation processes.
Ultimately, the revelations from the study of HL Tau highlight the interconnectedness of water with planetary formation, offering a glimpse into our own planet’s past evolution. As we continue to unravel the mysteries of the universe, discoveries such as these pave the way for a deeper understanding of the origins of planetary systems.

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.
