Supernovae come in two types. Core-collapse supernovae result from massive stars exhausting fuel. Thermonuclear supernovae are triggered by white dwarfs accreting mass or merging. Both produce expanding SNRs that can leave neutron stars or black holes.

⭐ The stars that guided ancient navigators are aging through cosmic epochs. Our Sun transforms across ten billion years, swelling from a G-type main-sequence star to a red giant, forging helium now, and later carbon and oxygen in its core.

The Star That Jumped Through Time 🌟⏳

Imagine finding a modern artifact inside an ancient fossil—that is the level of scientific paradox recently discovered by the Gaia telescope. Astronomers have spotted a red giant star orbiting the black hole Gaia BH2 that simply shouldn't exist as it currently does.

The Start of a Supernova

Stars about eight times more massive than our sun end their lives in supernovas, incredible explosions that rip the star apart. The earliest stages of this explosion are something we’ve never observed firsthand, until now. A new study reports observations of the supernova explosion SN 2024ggi, detected here on Earth on 10 April 2024. Only 26 hours later, researchers pointed the Very Large Telescope at it, capture data that revealed its oblong shape as the initial explosion reached the star’s surface.

What you see above and below are not the actual supernova. They are an artist’s conception of the event, based on the researchers’ observation data. That data is enough to rule out several existing supernova models and will no doubt guide new models of star death going forward. (Image credit: ESO/L. Calçada; research credit: Y.

Hot new #JWST image just dropped.

This is WR 70–16, a triple-star system better known as "Apep" after the mortal enemy of the sun god Ra in Egyptian mythology. The main pair of stars in the system is a rare binary composed of two Wolf–Rayet stars. These are evolved, massive stars that have completely lost their outer hydrogen atmospheres and are fusing helium (or heavier elements) in their cores. In time, these objects are thought to turn into supernovae. A third, hot supergiant star orbits the binary Wolf-Rayet stars with an orbital period of at least 10,000 years.

Wolf-Rayet stats are cosmic dust-making factories. A vast complex of cosmic dust shaped by furious stellar winds surrounds the system. The orbiting star/dust sources produces a pinwheel effect near the center of the image.

It's a highly dynamic system. According to NASA, "When the two Wolf-Rayet stars approach and pass one another, their strong stellar winds collide and mix, forming and casting out heaps of carbon-rich dust for a quarter century at a time." The dust produced by systems like this goes on to contribute to the formation of the next generation of both stars and planets.

Veil Nebula

These glowing wisps are the visible remains of a star that went supernova about 7,000 years ago. Today the supernova remnant is known as the Veil Nebula and is visible only through telescopes. In the image, red marks hydrogen gas and blue marks oxygen. First carried by shock waves, these remains of a former star now serve as seed material for other stars and planetary systems to form.
