For the first time, researchers observed a stellar disk in another galaxy.

The image of the star HH1177 system is not very uncommon. Except the system's location is in the Large Magellanic Cloud. This is the first time that a space telescope has taken an image of a star in another galaxy. The material disk around the star HH1177 belongs to a young star. And that shows that there is star formation in those galaxies.

The Large Magellanic Cloud is the Milky Way's companion galaxy. The existence of the young stars in that galaxy tells that the Milky Way hasn't pulled all gas and dust away from that galaxy. The material disk around the star HH1177 tells that there are also solar systems in the Large Magellanic Cloud and other dwarf galaxies. And that thing opens new visions for the galaxy's evolution.

With the combined capabilities of ESO’s Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, a disc around a young massive star in another galaxy has been observed. Observations from the Multi Unit Spectroscopic Explorer (MUSE) on the VLT, left, show the parent cloud LHA 120-N 180B in which this system, dubbed HH 1177, was first observed. The image at the center shows the jets that accompany it. The top part of the jet is aimed slightly towards us and thus blueshifted; the bottom one is receding from us and thus redshifted. Observations from ALMA, right, then revealed the rotating disc around the star, similarly with sides moving towards and away from us. Credit: ESO/ALMA (ESO/NAOJ/NRAO)/A. McLeod et al.

"This artist’s impression shows the HH 1177 system, which is located in the Large Magellanic Cloud, a neighboring galaxy of our own. The young and massive stellar object glowing in the center is collecting matter from a dusty disc while also expelling matter in powerful jets. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, a team of astronomers managed to find evidence for the presence of this disc by observing its rotation. This is the first time a disc around a young star — the type of disc identical to those forming planets in our own galaxy — has been discovered in another galaxy. Credit: ESO/M.

"This mosaic shows, at its center, a real image of the young star system HH 1177, in the Large Magellanic Cloud, a galaxy neighboring the Milky Way. The image was obtained with the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope (VLT) and shows jets being launched from the star. Researchers then used the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, to find evidence for a disc surrounding the young star. An artist’s impression of the system, showcasing both the jets and the disc, is shown on the right panel. Credit: ESO/A. McLeod et al./M.

Another thing that this kinds of research give is that helps to make models of when planet formation begins in the galaxies. The planets are necessary if researchers want to find lifeforms. If a galaxy comes too soon into the plasma halo of another larger galaxy, it loses its gas and dust. And that thing turns the galaxy into a stellar cluster. there is no star formation.

An interesting thing is that there could be planets around stars that are in the star clusters. The thing is that until now. Researchers couldn't take straight images from the stars in another galaxy or outside the Milky Way.

The Large Magellanic cloud has a spiral form. That means there must be some kind of gravity center in that galaxy. It's possible that inside the Large Magellanic Cloud is some kind of black hole. That thing explains why that galaxy still exists. The star formation requires disturbance in the gas cloud. That disturbance makes some kind of whirls. And those whirls turn gas into the stars.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to form the blue giant or too small it can collapse straight into a black hole . If the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts. The theory of hydrogen-burning supernovas consists model of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al. Ack.: CASU, CALET" (ScitechDaily, Astronomers Baffled by Ancient Galaxy That Mirrors Modern Milky Way) Researchers found the youngest Milky Way-type galaxy. The distance to the galaxy is enormous. And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

"New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) The transcendenc...
