Red giant star

Scientists published research related to a red giant star explosion they witnessed in real-time-- a first for the history of astronomy.

Remember in late 2019, when the famous red star Betelgeuse suddenly and mysteriously began dimming in brightness? Astronomers studying a similar star - VY Canis Majoris, one of the largest and brightest stars in our galaxy - commented that it's "behaving a lot like Betelgeuse on steroids."

How’s this for a depressing look into Earth’s potential future: astronomers have witnessed the first evidence of a planet’s destruction by its aging star as it expands into a red giant. “A similar fate may await the inner planets in our solar system, when the Sun becomes a red giant and expands all the way … Continue reading "A First: Star Caught in the Act of Devouring a Planet"

Grand star forming region R136 Stars are hot bodies of glowing gas that start their life in Nebulae. Stars form when enough dust and gas clump together because of gravitational forces. Nuclear reactions release energy to keep the star hot. They vary in size, mass and temperature, diameters ranging from 450x smaller to over 1000x larger than that of the Sun. The colour of a star is determined by its temperature, the hottest stars are blue and the coolest stars are red. The Sun has a surface…

It's easy to forget just how magical the universe we live in is. Here on Earth, life can be pretty normal, but far past what we can see with the naked eye lies some of the most mind-bending sights imaginable that reveal many secrets about humanity's and the universe origins. This reminds us that there is far, far more going on than we realize.
