T Coronae Borealis is a binary star system composed of a red giant and a companion white dwarf located in the constellation of Corona Borealis. Nicknamed the âBlaze Star,â it is a recurrent nova with a period of approximately 80 years. Very soon, it is expected to increase rapidly in brightness and astronomers worldwide are training their gaze to catch a glimpse of the expected nova event.

A star is dead? Keep your eyes on the skies, stargazers: NASA has predicted that the much-anticipated “once-in-a-life-time” star explosion — or nova — will be visible to the naked eye sometime this summer, per a recent press release. “It’s incredibly exciting to have this front-row seat,” said Dr. Rebekah Hounsell, an assistant research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dubbed T Coronae Borealis or the “Blaze Star,” the celestial event is located 3,000 light years away and is comprised of a white dwarf, an “Earth-sized” remnant of a dead star. The starburst’s mass, meanwhile, is...

In the coming months, the world is set to witness an extraordinary celestial event as a massive explosion in the T Coronae Borealis star system is poised to create a “new star” in the night sky. This rare astronomical event, expected to occur between now and September 2024, is not the birth of a star but rather an extraordinary nova outburst from T Coronae Borealis (T CrB), situated 3,000 light-years away in the constellation of Corona Borealis. NASA described the anticipated nova outburst as a “once-in-a-lifetime viewing opportunity” as T Coronae Borealis is predicted to become as bright as the...

Stars the mass of our Sun, and up to eight times more massive, evolve into red giants towards the end of their lives. Their outer layers puff up and expand millions of kilometres, their dusty, gassy shells blown away from the central star in relatively slow winds up to few hundreds of km/s. Even larger stars, up to 25–30 times more massive than the Sun, race through their fuel and explode in a supernova, sometimes leaving behind a spinning stellar corpse with a strong magnetic field, known as a neutron star. This tiny core packs the mass of nearly one...

Austin Kasso posted on his own Facebook page that he is disgusted that Memories Pizza of Walkerton, Indiana, has raised over $100,000 on a GoFundMe.com pageset up to help the restaurant get over the attacks on it fostered by the militant gay lobby and the media. But Kasso–the founder of Red Giant, a non-GMO food activist group–went further to vent his rage at Christians by going to the GoFundMe page to warn the pizza shop that he intended to rob them of the $100,000. St. Louis radio host Dana Loesch discovered Kasso’s threat and Tweeted it out… -snip Kasso, though, came...

Question: If Betelgeuse explodes right now, could we see it with naked eye? It is over 400 light years away, so you might think that people would see it long after it actually happens? Betelgeuse is already one of the brightest stars in the night sky, sitting somewhere around the 8th or 9th brightest star in the night sky. (These lists don’t include the Sun, which is somewhat obviously always the brightest object in the sky.) It sits in the constellation Orion, along with a number of other bright stars, and makes up the left hand shoulder of the warrior....

The ‘slow boat’ to Centauri concept we’ve discussed before in these pages envisions generation ships, vessels that take thousands of years to cross to their destination. And based on current thinking, that’s about the best we could manage with the propulsion systems currently in our inventory. Specifically, a solar sail making a close solar pass (a ‘sundiver’ maneuver) could get us up to 500 or 600 kilometers per second (0.002c), making a 2000-year journey to the nearest star possible. It’s hard to imagine under what circumstances such a mission might be launched.But let’s think long-term, as Greg Matloff (New York...

HERE IS THE STORY. A black activist commissioner in Dallas County was upset in a meeting by the use of the term "black hole." I called the Commissioners Court and asked for Commissioner Price. They connected me with his secretary, Melanie. We had a nice friendly conversation. It is not racist, and I am not afraid to say it, but her voice indicated that she was a black lady. MELANIE: Commissioner Wiley. DFU: Yes, ma'am, I'm Doug and I'm calling from California about the story of the black hole and Commissioner Wiley. M: Yes, sir. (sort of a little...

Long before the Bible's tale of Jonah being swallowed by a whale, a small wannabe star has emerged intact after being engulfed by a neighboring giant star, scientists say. The victim was a brown dwarf, a failed star too small to sustain the nuclear reactions that ignites regular stars. The purpetrator was a red giant, an ancient star that once resembled our Sun but which puffed up to enormous size after its hydrogen fuel was depleted. The red giant has since expelled most of its gas into space and transformed into a dense, Earth-sized star called a white dwarfs. Using...
