Astronomers just casually witnessed the birth of a new solar system
Astronomers have witnessed the creation of a solar system for the first time. Data captured by the ALMA telescope in Chile and the James Webb Space Telescope showed planets forming around a star in the first record of its kind. The findings, detailed in a study published on Wednesday, showed how scientists observed a gaseous plate being formed around a star – the first step in the birth of a new solar system. Professor Melissa McCure from the Leiden University in the Netherlands said: 'For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our Sun.' The new solar system is being formed around a baby or 'proto' star named HOPS-315 located some 1300 light-years from Earth. Scientists believe the unique sighting can paint a picture of how our solar system was formed, as well as help us better understand the planetary formation process. Merel van't Hoff, of Purdue University in the USA, who co-authored the study, said the nascent planetary system resembles what our solar system would have looked like when it was beginning to form. She said: 'This system is one of the best that we know to actually probe some of the processes that happened in our Solar System.' A solar system is formed from solid material within meteorites, which condense and then bind themselves together. More Trending The pieces of matter begin to form tiny planets or 'plantesimals' before they form larger full size planets. The first minerals around HOPS-315 were detected by the James Webb Space Telescope, before the ALMA Telescope was used to identify exactly where they originated. ESO astronomer Elizabeth Humphreys, who manages the European ALMA Programme Manager said she was 'really impressed' with the study. She said: 'It suggests that HOPS-315 can be used to understand how our own Solar System formed. This result highlights the combined strength of JWST and ALMA for exploring protoplanetary discs.'

See the baby solar system astronomers just spotted forming a planet for the first time
Outside our own solar system, the first moments of planet formation have never been detected, until now. Astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and Nasa's James Webb Space Telescope in orbit to observe the earliest moments when specks of dust began tumbling into what will become planets. New Images Released Of 'Interstellar Wanderer' Zooming Through Our Solar System The European Southern Observatory (ESO) said the images are of a "baby star" known as HOPS-315 located about 1,300 light-years from Earth. The images and findings were published in the journal Nature on Wednesday. Study co-author and Purdue University Professor Merel van 't Hoff compared the images to "a picture of the baby Solar System … seeing a system that looks like what our Solar System looked like when it was just beginning to form." According to ESO, the image above shows HOPS-315. The orange is carbon monoxide blowing away from the baby star. In blue, there is a jet of silicon monoxide, which will eventually become the solid material to form planets. Previously, astronomers have observed giant planets, like Jupiter, forming in the giant discs around young stars. According to the ESO, this discovery shows the first minerals condensing and growing in size and mass. Eventually, this process will form planets. The illustrations on the right of the above image show this process happening around baby star HOPS-315 as molecules of silicon monoxide condense into solid silicates. Largest Chunk Of Mars Discovered On Earth Sells At Auction For $5.3 Million The minerals were first identified by the James Webb Space Telescope and then the signals were pinpointed by ALMA. The ALMA image above shows the jets of silicon monoxide blowing away from the star.

History made in space! Astronomers spot a solar system forming for the first time
What makes HOPS-315 so special? Live Events How do planets begin to form around stars? Could this explain how Earth was born? FAQs (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel For the first time, scientists have observed planets forming around a star other than our used the James Webb Space Telescope and ALMA to observe planet-building material forming near the young star. This stunning discovery may help us understand how our own solar system formed 4.6 billion years have observed the first solid materials forming around a young star known as HOPS-315 , the earliest stage of planet formation ever seen outside of our solar emergence of a planetary system that may eventually resemble the solar system has been observed by astronomers. The team was able to determine when the young star HOPS-315, which is about 1,300 light-years away, started to form the specks of material that will eventually form from the Atacama Large Millimeter/submillimeter Array (ALMA), a network of 66 radio telescopes situated in the northern Chilean desert, and observations from the James Webb Space Telescope (JWST) enabled the discovery, as per a report by McClure, a professor at Leiden University in the Netherlands and the study's lead author, says, "For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our Sun." The study was published in Nature today.'We're seeing a system that looks like what our Solar System looked like when it was just beginning to form," says co-author Merel van 't Hoff, a professor at Purdue University in the United States, who likens their findings to "a picture of the baby Solar System." The team's findings were released in the journal Nature on Wednesday, July 16, as per a report by HOPS-315, a "proto" or baby star that is located about 1300 light-years away from us and is comparable to the young Sun, this newborn planetary system is beginning to frequently observe "protoplanetary discs," which are discs of gas and dust that are the birthplaces of new planets, around such baby in order to observe the birth of these new "exoplanets," or extrasolar planets, astronomers had to detect protoplanetary disks meteorites that have fallen to Earth, scientists can find a clue about what they should be searching for in these disks in their early stages. Meteorites are pieces of asteroids that formed during the formation of our solar system's planets 4.6 billion years ago. Meteorites, like those found in the protoplanetary disk around the sun during the early solar system, are rich in crystalline minerals that contain silicon monoxide, which condenses at high team found evidence of hot minerals condensing in the protoplanetary disk whirling around HOPS-315. They specifically found silicon monoxide in crystalline materials and as a gas surrounding this young star. This process has never been observed outside of our solar system or in a protoplanetary have discovered evidence that these hot minerals are starting to condense in the disc around HOPS-315. According to their findings, SiO is found both inside these crystalline minerals and surrounding the baby star in its gaseous state, indicating that it is only now starting to solidify. This process has never been observed outside of our Solar System or in a protoplanetary acting as a stand-in for young solar systems throughout the galaxy, the disc of HOPS-315 offers astronomers a fresh chance to investigate early planet formation and a fantastic analog for researching our own cosmic discovered early signs of solid materials, which are the basic building blocks of helps scientists understand how planets like Earth might have formed billions of years ago.

Cosmic Baby Photo: Scientists Catch Rare First Glimpse Of Planets Being Born Around A Sun
The young star, named HOPS-315, is located approximately 1,300 light-years away from Earth. It is classified as a protostar, a star in the earliest phase of development An unprecedented achievement has been made in the field of space science. For the first time, scientists have observed the earliest stages of planet formation around a newborn star similar to our Sun. This remarkable discovery was made by an international team of scientists using the James Webb Space Telescope (JWST) and the ALMA telescope. The young star, named HOPS-315, is located approximately 1,300 light-years away from Earth. It is classified as a protostar, a star in the earliest phase of development. Surrounding HOPS-315 is a protoplanetary disc made of gas and dust, which serves as the birthplace of new planets. First Signs of Planet Birth Within this disc, scientists have detected the presence of hot mineral molecules that are beginning to solidify. These minerals eventually form planetesimals, small rock-like bodies that gradually combine to become planets. Lead researcher Melissa McClure from Leiden University stated, 'This is the first time we've observed when and how planet formation begins. It offers a crucial insight into the origins of our own solar system." Co-author Merel van 't Hoff from Purdue University described the discovery as 'a childhood photo of our solar system." The key molecule identified was silicon monoxide (SiO), a mineral also found in the early rocks of Earth and other planets. These minerals, initially in gas form, are now crystallising, marking the first solid step in planet formation. Striking Similarities With Our Solar System What makes this even more intriguing is that the signals of silicon monoxide came from the same region of the disc where the asteroid belt exists in our own solar system. According to Logan Francis (Leiden University), 'We're seeing the same minerals in the same location as we do in our solar system. It's a fascinating parallel." Why HOPS-315 Is So Special The disc around HOPS-315 acts as a natural laboratory, helping us understand the early formation of solar systems. According to Elizabeth Humphreys of the European Southern Observatory (ESO), 'HOPS-315 provides a unique opportunity to study the cosmic history of our own solar system." This discovery is not just a scientific milestone; it opens a window into how worlds like ours come into being. view comments Disclaimer: Comments reflect users' views, not News18's.
