The star is just about eight million years old, but is already on the verge of becoming a supernova. When that happens, the resulting explosion will be visible from Earth, even in broad daylight.
The star has been observed in many other wavelengths, particularly in the visible, infrared, and ultraviolet. Using ESO’s Very Large Telescope astronomers discovered a vast plume of gas almost as large as our Solar System. Astronomers have also found a gigantic bubble that boils away on Betelgeuse’s surface. These features help to explain how the star is shedding gas and dust at tremendous rates (eso0927, eso1121). In this picture, ALMA observes the hot gas of the lower chromosphere of Betelgeuse at sub-millimeter wavelengths — where localised increased temperatures explain why it is not symmetric. Scientifically, ALMA can help us to understand the extended atmospheres of these hot, blazing stars.
This year’s episode of the grand meteor shower the Leonids will peak on Monday morning before dawn. The meteors are bits of debris dropping off the comet Tempel-Tuttle that intersects Earth’s orbit every November. Unfortunately, it may be tough to see many shooting stars because activity this year will be low and the waning gibbous […]
The Gateway Foundation is a private company that claims they could build the first orbital space hotel by 2025. According to their site, the Von Braun Rotating Space Station is designed “to accommodate both national space agencies conducting low gravity research and space tourists who want to experience life on a large space station with […]
Concerned about your eyesight? You probably should be. And we’re not just talking about seniors here. Young or old, we’re all at risk of coming down with vision issues Most of us might get a vision test only once every couple of years or so when we get a new pair of glasses – if […]
We love our smartphones and tablets, but we also love to write. For a while now, there hasn’t been a workable solution. Either hook it up to a keyboard (which defeats the purpose of a portable gadget) or resign ourselves to typing on tiny, unresponsive glass icons. Looks like technology has finally caught up to […]
So you’ve got an iPhone 11 Pro Max. It’s an impressive piece of hardware – sometimes, too impressive. The more you’re compelled to use it, the more an age-old problem pops up: The dreaded low battery warning. Even if you’re on the go, perhaps the best solution to this is also pretty unobtrusive. It’s the […]
