Imaged by the Atacama Large Millimeter Array (ALMA), this is the most detailed depiction yet of the enormous supergiant Betelgeuse, 600 light-years off in the constellation Orion and 1400 times the size of the sun.
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.
NASA’s AIRS instrument captured this image of Tropical Storm Fay around 2 p.m. local time on July 10, 2020, as the storm swept through New England. Image: NASA/JPL-Caltech From NASA’s Jet Propulsion Laboratory: Tropical Storm Fay is sweeping across New England, with the center of the storm making landfall about 10 miles (15 kilometers) north-northeast […]
DAIN is an AI-powered method for adding “missing” frames of footage. Standard interpolation treats the existing frames as flat fields of color and contrast, but the AI models the depth of regions in the scene, resulting in a more convincing and less “smeary” results. Let’s go for a ride on the moon! Apollo 16 Rover […]
Next year, the United States Mint will release a silver dollar coin commemorating astronaut and elementary school teacher Christa McAuliffe who died with her six crewmates when the Space Shuttle Challenger exploded after liftoff on January 28, 1986. The candidate coin designs (below) were presented to the Citizens Coinage Advisory Committee (CCAC) and the group’s […]

Meditation seems simple. Just sit on the floor, clear your mind, and zen out. But have you tried sitting cross-legged on the floor without moving for even 10 minutes? It starts getting mighty uncomfortable after a while. And if you’ve got a few years on you, the knees and thighs are going to be barking […]
