Researchers have discovered a population of mysterious stars in the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. This discovery could provide insights into hot helium stars, which are thought to be the beginning of neutron star mergers and hydrogen-poor core-collapse supernovae. 

Here are some other recent discoveries about stars and galaxies: 

• NGC 346 NASA’s James Webb Space Telescope has shed light on this star-forming region in the Small Magellanic Cloud, a dwarf galaxy close to the Milky Way. 
• Magellanic Stream Scientists have discovered stars within the Magellanic Stream, a river of hydrogen gas from two small galaxies. 
• Intergalactic stars Vanderbilt astronomers have identified over 675 stars at the edge of the Milky Way, between the Andromeda Galaxy and the Milky Way. They believe these stars are hypervelocity (intergalactic) stars that were ejected from the Milky Way’s Galactic Center.

Researchers suspect the stars are precursors to neutron star mergers and hydrogen-poor supernovae. The universe teems with systems of two stars orbiting each other in a seemingly endless cosmic dance

Astronomers have discovered a population of stars that may be precursors to hydrogen-poor supernovae and neutron star mergers. 

The stars are massive and have had their hydrogen envelopes stripped by their companions in binary systems. They are located in the Large and Small Magellanic Clouds, which are nearby satellite galaxies of the Milky Way. 

The stars are believed to be hot helium stars, which are thought to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers. 

Neutron star mergers are the same mergers that emit gravitational waves detected by the LIGO experiment.

The stars are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers. The lack of hydrogen in these supernovae suggests that the precursor stars lost their thick hydrogen-rich envelopes. 

The star systems are also thought to be necessary to form neutron star mergers, like those that emit gravitational waves detected from Earth by the LIGO experiment.

The Large and Small Magellanic Clouds are two of the Milky Way’s closest dwarf galaxies. The Large Magellanic Cloud (LMC) has about 20 billion stars and the Small Magellanic Cloud (SMC) has about 3 billion. 

The stars could also provide clues about the history of the two galaxies. The Magellanic Stream, as it is known, previously appeared to be devoid of stars, despite astronomers predicting they should exist. 

The discovery of these stars has also revealed the true distance to the Magellanic Stream, which extends from 150,000 light-years to more than 400,000 light-years away.

The Magellanic Clouds are of interest to astronomers for a number of reasons: 

• Proximity The Magellanic Clouds are some of the closest galaxies to the Milky Way, making them useful for studying star formation and galactic evolution. 
• Stellar formation The Magellanic Clouds contain many young stars and star clusters, including R136a1, the most massive known star. 
• Irregular shape The Magellanic Clouds are thought to have been shaped by galactic tides from the Milky Way, making them irregular. 
• Dark matter The stability of the Magellanic Clouds can be used to determine the Milky Way’s total mass. 
• Cosmic noon Materials in the Small Magellanic Cloud may represent a period when many stars and planets were forming. 

The Magellanic Clouds are also independent galaxies, but close enough to the Milky Way that astronomers can observe individual stars

Here are some people who have studied the Magellanic Clouds: 

• John Herschel In 1847, Herschel wrote a report about the Magellanic Clouds, detailing 919 objects in the Large Magellanic Cloud and 244 objects in the Small Magellanic Cloud. 
• Henrietta Swan Leavitt Leavitt studied the Large and Small Magellanic Clouds from Harvard College Observatory in Southern Peru. She is known for her work on Cepheid variable stars and discovered the period-luminosity relation for Cepheids while studying variable stars in the SMC. 
• Edwin Hubble Hubble established the extragalactic nature of the Magellanic Clouds, which are now called galaxies. 
• ‘Abd al-Rahman al-Sufi Shirazi In 964 AD, Shirazi, also known as “Azophi”, wrote about the Large Magellanic Cloud in his Book of Fixed Stars, referring to it as Al Bakr, the White Ox. 

The Magellanic Clouds were first observed in the 10th century by the Persian astronomer Al Sufi.
