Birth of planet captured: Astronomers share rare glimpses of newborn planet about 1,300 light-yrs away
For the first time, a team of researchers has captured the birth of a planet around a star beyond our Sun. The observations captured the very beginnings of planet formation , a rare glimpse into the cosmic process that gives rise to Earth-like planets around a star. Observations were made using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope and NASA's James Webb Space Telescope to capture the formation of a new planetary system. Scientists detected the formation of the first specks of planet-building material around a baby star named HOPS-315 , located about 1,300 light-years away. HOPS-315 is considered a 'proto-star', meaning it's in the earliest stage of stellar evolution. These young stars are often surrounded by protoplanetary discs - rotating clouds of gas and dust where planets are born.

The findings were published in the journal Nature . The team found evidence of silicon monoxide (SiO) gas and solid crystalline minerals in the disc surrounding HOPS-315. This suggests that planet-forming materials are beginning to condense from gas into solid particles, an evolutionary phase in the birth of planets. "This process has never been seen before in a protoplanetary disc — or anywhere outside our Solar System," said Edwin Bergin, co-author and professor at the University of Michigan, USA. The discovery unveils a never-before-seen phase in planet formation and opens a new window into studying how planetary systems like our own come into being.

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.'

Astronomers witness dawn of new solar system for 1st time
Astronomers have witnessed the birth of a solar system beyond our own for the first time. An international team of researchers has been able to pinpoint the exact moment when planets began to form around a star by using data captured by the ALMA telescope in Chile and the James Webb Space Telescope, according to a study published in Nature on Wednesday. MORE: 100 undiscovered galaxies could be orbiting the Milky Way, according to new research The astronomers observed hot minerals just beginning to solidify – the first specks of planet-forming material, the astronomers said. A gaseous disk surrounding the young star is the first stages of the assembly process to form a new planetary system, according to the paper. "For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our Sun," Melissa McClure, a professor at Leiden University in the Netherlands and lead author of the study, said in a statement released by the European Southern Observatory (ESO). Planets and small bodies like those in our solar system likely formed through the mixture of interstellar solids with rocky solids that condense from the hot gases surrounding a young host star, astronomers hypothesize. But the specific process of the solar system's formation remains unclear. In our solar system, the first solid material to condense near Earth's present location orbiting the sun is found trapped within ancient meteorites, according to the ESO. Over time, the newly condensed solids bind together and begin the planet formation process as they gain both size and mass. MORE: Webb telescope discovers stars forming in 'toe beans' of Cat's Paw Nebula Researchers say they found evidence that these hot minerals have begun to condense in the disc surrounding the young star, or protostar, named HOPS-315. "This process has never been seen before in a protoplanetary disc – or anywhere outside our solar system," said Edwin Bergin, an astronomer at the University of Michigan and co-author of the paper, in a statement. The protostar is located in the Orion B molecular cloud, around 1,300 light-years from Earth, according to the paper, and is positioned in a way that allows a direct view of its inner gaseous disk. One light year is approximately 5.9 trillion miles. The view is rare because jets of gas emitted by protostars, known as outflow, often block the view of the disk, the researchers said. MORE: Astronomers spot 'interstellar object' speeding through solar system Astronomers were able to observe solids starting to condense from the cooling gas – known as "time zero" for planet formation – by using infrared and millimeter wavelengths from the ground- and space-based telescopes, the researchers said. The Webb telescope, the most powerful telescope ever launched into space, was used to probe the chemical makeup of the material around the protostar, detecting crystalline silicate materials that are a "telltale sign" of early planet formation, according to the paper. The chemical signals appear to be coming from a small region of the disc around the star that's equivalent to the orbit of the asteroid belt around our own sun, according to the ESO. "This hot mineral is the first feedstock that you have to start growing things in the dark," McClure said. The finding marks the first time a planetary system has been identified at such an early stage. While astronomers have previously seen young discs that contain newborn, massive planets like Jupiter, it was not yet proven that the first solid parts of nascent planets, known as planetesimals, must form further back in time, at earlier stages, McClure said. The discovery opens a window into the past of our own solar system, since the formation of the new system likely mimics the conditions that occurred at the dawn of the planetary system that is home to Earth, astronomers said. "This system is one of the best that we know to actually probe some of the processes that happened in our solar system," said Merel van 't Hoff, an astronomer at Purdue University and co-author of the study, said in a statement released by Nature.

HOPS-315: Scientists spot birth of a new solar system for first time
Astronomers say they have observed the moment when planets start forming around a distant star for the first the earliest stage of planet formation ever seen by new planetary system is taking shape around HOPS-315, a baby star which is located 1,300 light years from Earth in the Orion say that the discovery could help better understand the beginnings of our own Solar System. What have scientists discovered? HOPS-315 is a baby star, which looks like our own Sun in its youth, and is located 1,300 light years from Earth in the Orion Nebula.A team of international researchers used the ALMA telescope in the Chilean desert along with the James Webb Space Telescope in order to witness the moment when planets began to form around HOPS-315. Experts say that they saw the creation of the first specks of planet-forming material around HOPS-315 - hot minerals which are just beginning to minerals were first spotted by the James Webb Space team then used the European Southern Observatory's ALMA telescope to find out exactly where the chemical signals were coming discovered that these minerals were found in a small portion of the disc which is similar to the asteroid belt that surrounds our say that this discovery could allow them to see what the formation of our own Solar System may have been like billions of years ago."We're seeing a system that looks like what our Solar System looked like when it was just beginning to form," study co-author Merel van 't Hoff from Purdue University in America author, Melissa McClure of Leiden University in the Netherlands, added: "For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our Sun."
