Discharged by gas and dust from an exploding star, the neutron star is playing a winning hide-and-seek game.

When a giant star exploded on a supernova 32 years ago, it must leave behind an incredibly dense core, known as a neutron star. But the giant blast, dubbed the Supernova 1987A, releases gas and dust into the cosmos like a baby throwing pasta around its high chair – it's a magical romance. All the excess dust obscured our view of the neutron star, but using sharp new images, astronomers found the zombie star hiding. Array (ALMA) to examine the dense cloud of dust surrounding the Supernova 1987A, positioned in the Large Magellanic Cloud, some 168,000 light-years from Earth. Gazing through the dense space of smog, astronomers found a patch of dust that they believed enabled the neutron star.

"For the first time we can say that there is a neutron star inside this cloud inside the supernova's lip," said Phil Cigan, astronomer at Cardiff University and first author of the study, in a press release. "Its light is obscured by a thick cloud of dust, blocking the direct light from the neutron star at many wavelengths like the fog forming a spotlight."

The 66 ALMA-forming telescopes were located in the Chilean desert and were used in collaboration with the Event Horizon Telescope team to snap the first ever image of a black hole earlier this year . Researchers used the array to observe the lengths of the submillimeter light, which helped restore the dust curtain to the hidden star. , eventually revealing a ton of knowledge about the lives of giant stars, what happens when they collapse and what the star afterlife looks like. neutron stars who hide and seek heroes. Other researchers post further collapse that could result in a black hole or an unusual type of star known as a "quark star" filled with strange particles and strange physics.
