Do you know there\u2019s an object in space astronomers named \u2018unicorn\u2019? This cute name was given to a really weird blinking light astronomers spotted while observing the sky. You might think it was a star or a spaceship, but it wasn\u2019t\u2026 it was something totally different because it didn\u2019t blink randomly. Instead, it followed a strange rhythm, like it had its own beat. Are you curious to know more about this \u2018unicorn\u2019 in space? Let\u2019s see what makes this mysterious light so special and if it matters for the future.<\/p>\n
A unicorn in space? Well\u2026 almost<\/p>\n
Looking at the sky is a common thing to do, but one day some astronomers were doing this and they found something incredible: the CHIME J1634+44. This caught their attention because it was blinking in a very strange way. However,\u00a0 the most curious thing is that they\u2019ve compared it to a \u201cunicorn\u201d in space, because it\u2019s unique and unlike anything they\u2019ve seen before. (More beautiful and easier name to call this strange object, right?).<\/p>\n
This object is thousands of light-years away from Earth (really, really far!) and behaves in a way that nobody really understands. It lights up, goes dark, lights up again\u2026 but it does this on two different time intervals: one every 14 minutes, and another every 70 minutes. That\u2019s already pretty strange. But what\u2019s more, it seems to be spinning faster and faster, which usually doesn\u2019t happen in space.<\/p>\n
What is this strange object?<\/p>\n
Scientists believe it could be a very small and very dense star, something that\u2019s left behind after a big star \u201cdies.\u201d There are two types that could fit: white dwarfs and neutron stars<\/a>. Both are super compact, like fitting a ton of stuff into a super tiny box. Neutron stars, for example, can have more mass than the Sun but are only about 20 kilometers wide. They\u2019re incredibly dense.<\/p>\n And why does it blink?<\/p>\n That\u2019s what they are trying to figure out. Some neutron stars emit radio waves regularly, like they\u2019re sending signals into space. These are called pulsars, and scientists think this object could be one of them. But there are others who think it could be a white dwarf that also emits this kind of signal, although that\u2019s much more rare.<\/p>\n What\u2019s clear is that this object doesn\u2019t behave like anything they have seen before. For example, its light is \u201cpolarized\u201d in a completely perfect way, something never seen in an object like this. It\u2019s like it\u2019s following a rule we don\u2019t know yet.<\/p>\n What now?<\/p>\n Astronomers want to keep observing it more closely and find out more about it. Sometimes in science, when something doesn\u2019t fit what was known before, that\u2019s when the important discoveries begin. CHIME J1634+44 could help us understand much more about how these strange stars work, and whether there are more like it hiding out there. In case they are really important for us, it would be a good idea to see if there are more \u2018unicorns\u2019 to study.<\/p>\n What does all this mean for us?<\/p>\n
