‘Blaze star' might go nova soon; what to expect
SPACE (KXAN) — A rare nova could occur in the next few nights. Called T Coronae Borealis, the 'Blaze Star' and 'T CrB' by astronomers, the binary star system could produce an explosion visible to the naked eye. Located about 3,000 light years from Earth, the 'Blaze Star' is actually two stars. One is a white dwarf star, dead and shriveled, about the size of Earth. The other is an ancient red giant star that's slowly being devoured by the smaller star. According to NASA, during a nova event, the white dwarf releases a massive explosion. The star will stay intact after this explosion, unlike during a supernova, in which the star explodes. These explosions reoccur every few years. The explosion will create a bright spot in the sky that will last about a week. The last time the star's eruption was seen happened in 1946. The 'Blaze Star' is located in the 'Northern Crown,' a horseshoe-shaped curve of stars located to the west of the Hercules constellation. This constellation is found by looking east. According to NASA, the best way to locate the star is to find Arcturus and Vega, two of the brightest stars in the night sky this time of year, and drawing a line between them. The star will be visible about four hours after sunset this month. Once it explodes, the bright nova will be about the same brightness as the North Star. The 'Blaze Star' was originally expected to explode in 2024. The dimming of the star system that year led many to believe it would explode soonish. 'Recurrent novae are unpredictable and contrarian,' said Dr. Koji Mukai, a fellow astrophysics researcher at NASA Goddard, in a statement released last year. 'When you think there can't possibly be a reason they follow a certain set pattern, they do – and as soon as you start to rely on them repeating the same pattern, they deviate from it completely. We'll see how T CrB behaves.' It is important to note, because of the distance between the Earth and this star system, that we're actually seeing an explosion that occurred 3,000 years ago. Because the system is 3,000 light-years away, it takes 3,000 years for the light to actually reach us. Copyright 2025 Nexstar Media, Inc. All rights reserved.

A Star May Explode This Week in a Once-in-a-Lifetime Event—Here's How to See It
T Coronae Borealis, a binary star system located 3,000 light-years away from Earth, may be visible to the naked eye this week. This phenomenon last happened in 1946 and won't occur again for about another 80 years. Once it reaches its peak brightness, T Coronae Borealis will be visible for several days to the naked eye.A star system located 3,000 light-years away from Earth may become visible to the naked eye this week—a phenomenon that only happens about once every 80 years. T Coronae Borealis is a binary star system in the constellation Corona Borealis. Per the National Aeronautics and Space Administration (NASA), its magnitude is normally +10, which is too dim to see with the unaided eye. Per NASA, when the star explodes—an event known as a nova outburst—its magnitude will jump to +2, making it as bright as the North Star. The last time this happened was in 1946. According to NASA, the star system consists of a white dwarf and red giant. The stars are close enough that, as the red giant becomes unstable and begins ejecting its outer layers, the white dwarf collects that matter onto its surface. The atmosphere of the white dwarf heats enough to cause a reaction that produces the nova we see from Earth. While the exact day and time the nova outburst occurs is unknown, a paper published by the American Astronomical Society (AAS) estimates that T Coronae Borealis will explode on March 27, 2025. If the nova outburst doesn't happen this week, AAS notes that November 10, 2025, is also a possible date for this event. Once its brightness peaks, T Coronae Borealis should be visible for several days to the naked eye and over a week with binoculars before dimming again, NASA estimates. While you wait, the space agency says to become familiar with the constellation Corona Borealis, also known as the Northern Crown, where the outburst will take place. It's a small, semicircular arc near Bootes and Hercules. Related: 3 Full Supermoons Will Light Up the Night Sky in 2025—Here's How and When to See Them Read the original article on Martha Stewart

Find The ‘Blaze Star' Among The Stars Of Spring: The Weekend Night Sky
Late-March seeing the stars of spring appear, bringing new shapes and constellation — and possibly ... More an exploding star in the constellation Corona Borealis, the "Northern Crown." Each Friday, I pick out North America's celestial highlights for the weekend (which also applies to northern hemisphere mid-northern latitudes). Check my main feed for more in-depth articles on stargazing, astronomy, eclipses and more. Spring started yesterday, with the vernal equinox bringing equal nights of light and dark to everywhere on our planet. However, sky-watchers already know that spring is here, with late-March seeing the stars of spring appear, bringing new shapes and constellation — and possibly an exploding star. It's also wise to look out for the Northern Lights, which tend to strengthen around the equinoxes. Here's everything you need to know about stargazing this weekend: These are the constellations that can be seen in spring. They include the Great Spring Triangle. The ... More design features a forest and a telescope. Here's celestial proof that spring has arrived in the Northern Hemisphere. Face northeast and you'll see the Big Dipper with its handle facing down towards the horizon. Follow that handle in an arc and you'll come to Arcturus low in the eastern night sky — a red giant star about 37 light years distant and the fourth-brightest in the night sky. Now take a spike to the southeast and you'll see Spica just above the horizon. Spica is 261 light years distant. Now find Denebola in the springtime constellation Leo to make the shape of a equalateral triangle — the 'Great Spring Triangle.' The moon reaches its last quarter phase tonight, shining half-lit in the constellation Sagittarius. More importantly for stargazers, the last quarter has the moon rising at midnight. That clears the way for about 10 completely moonless evening night skies ideal for finding constellations How To Find Corona Borealis. If there's one thing to find this weekend, it's Corona Borealis, the 'Northern Crown.' This curl of seven stars between the constellations Boötes and Hercules could be about to host an eighth bright stars — but just for a few days. If astronomers are correct, a dim binary star called T Corona Borealis (or T CrB and he 'Blaze Star' for short) may go nova and explode on March 27, becoming 1,000 times brighter. Here's how to find it in the east about three hours after sunset. The times and dates given apply to mid-northern latitudes. For the most accurate location-specific information, consult online planetariums like Stellarium. Wishing you clear skies and wide eyes.
