The Webb gets a good closer look at an exoplanet

Exoplanets are hard to spot but the James Webb Space Telescope got an image of one (HIP 65426b), reported September 1: The planet is more than 10,000 times fainter than its host star and about 100 times farther from it than Earth is from the Sun (~93 million miles), so it easily could be spotted when the telescope’s coronagraphs removed the starlight. The exoplanet is between six and 12 times the mass of Jupiter—a range that could be narrowed once the data in these images is analyzed. The planet is only 15 million to 20 million years old, making it very young compared to our 4.5-billion-year-old Earth.

Sci-fi Saturday: An Asteroid Lingers Near Earth and Devours Time

Or, at any rate, it devours our perception of time, as one man discovers

“Flyby,” a short sci-fi film at DUST by Jesse Mittelstadt (January 28, 2021 13:22 min) “When a passing asteroid begins to affect how people perceive time, one man struggles to keep up with a life that is quickly disappearing into the future.” Note: Language and mature scenes warning. When watching the opening sequence of “Flyby,” it’s hard not to think of space cigarillo Oumuamua, for which Harvard astronomer Avi Loeb made the case that it was an extraterrestrial lightsail. Loeb has recently published a book on these and similar reflections, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth (Houghton Mifflin Harcourt (January 26, 2021). Back to the film, which takes quite a different tack, of course, addressing altered perceptions Read More ›
