Astronomers may have caught a baby planet in the act of being born around a star, sculpting beautiful spiral arms into the dusty disc that surrounds it.<\/p>\n

Using the European Southern Observatory\u2019s Very Large Telescope (VLT), researchers believe they\u2019ve found a planet forming in real time, deep within a swirl of gas and dust 440 lightyears away.<\/p>\n

This newborn exoplanet is twice the size of Jupiter and, as it orbits its star, is leaving giant spiral patterns in its wake.<\/p>\n<\/p>\n

A peek into planetary origins<\/p>\n

The planet-in-the-making was discovered orbiting a young star<\/a> called HD 135344B.<\/p>\n

This star is surrounded by a protoplanetary disc, a massive disc of gas and dust that serves as the raw material for planets.<\/p>\n

And right at the base of one of the disc\u2019s grand spiral arms, astronomers spotted something extraordinary: a bright object that looks like a growing exoplanet<\/a>.<\/p>\n

“What makes this detection potentially a turning point is that, unlike many previous observations, we are able to directly detect the signal of the protoplanet, which is still highly embedded in the disc,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, and lead author of the study.<\/p>\n

“This gives us a much higher level of confidence in the planet\u2019s existence, as we\u2019re observing the planet\u2019s own light.”<\/p>\n

Until now, scientists could only infer a new-forming planet\u2019s existence around this star, based on the shapes in these discs.<\/p>\n

Now they\u2019ve caught one shining through the dust.<\/p>\n

\nMeet the growing planet<\/p>\n

The suspected planet is located as far from its star as Neptune is from our Sun, and is estimated to be around twice Jupiter\u2019s mass.<\/p>\n

As the planet sweeps through the disc, it\u2019s pulling material toward itself and sending shockwaves through the gas, carving the sweeping spiral arms astronomers can now see with clarity.<\/p>\n

Those spirals were first spotted years ago using an instrument called SPHERE on the VLT, years ago.<\/p>\n

But no one had managed to catch the planet thought to be causing them until now, thanks to a newer, sharper tool called on the VLT called the Enhanced Resolution Imager and Spectrograph (ERIS).<\/p>\n

This marks the first time astronomers have detected an exoplanet nestled inside a disc spiral, right where they thought it would be.<\/p>\n

\nAnother mysterious companion<\/p>\n

A second team of astronomers also used ERIS in a separate study, taking a close look at V960 Mon, a star even younger than HD 135344B.<\/p>\n

Again, previous studies showed its disc was fragmenting in a chaotic process known as gravitational instability.<\/p>\n

This is when chunks of material collapse in on themselves, potentially forming planets or even bigger objects.<\/p>\n

With ERIS, the researchers discovered a bright, compact companion lurking near one of the disc\u2019s spiral arms.<\/p>\n

It could be a giant planet forming through gravitational instability, or perhaps a brown dwarf, a kind of failed star, too big to be a planet but too small to ignite as a true star.<\/p>\n

For astronomers, this is about as close as we\u2019ll ever get to watching planets being born.<\/p>\n

“We will never witness the formation of Earth,” says Maio. “But here, we may be watching a planet come into existence in real time.”<\/p>\n","protected":false},"excerpt":{"rendered":"Astronomers may have caught a baby planet in the act of being born around a star, sculpting beautiful…\n","protected":false},"author":2,"featured_media":15664,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[90,416,56,54,55],"class_list":["post-15663","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-science","tag-space","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/15663","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=15663"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/15663\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/15664"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=15663"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=15663"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=15663"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
