What time is it on the moon? US House space committee wants a standard lunar clock

NeRD

We are one step closer to getting a lunar time zone this week, as a bill passed out of the US House Science, Space and Technology committee directs the administrator of NASA to develop a way to coordinate and measure time on the moon. The bill is titled The Celestial Time Standardization Act (or HR 2313), and was passed out of committee by a voice vote on Tuesday (April 29). It now goes to the full House for a future floor vote. If it passes the House (and then the…

What would it be like living on Tatooine from ‘Star Wars’? This exoplanet orbiting twin suns could tell us

NeRD

A Tatooine-like world with a key difference from the desert planet in “Star Wars” has been serendipitously discovered orbiting not two stars, but a pair of brown dwarfs. What’s more, this wacky planet doesn’t orbit around the brown dwarfs’ equator, but instead up and down over their poles. In the “Star Wars” universe, Luke Skywalker famously came from the planet of Tatooine, which had two suns and double sunsets. Tatooine is in a circumbinary orbit, which means that it doesn’t orbit one star, but instead orbits both stars of a…

A whole ‘population’ of minimoons may be lurking near Earth, researchers say

NeRD

Earth’s minimoon may be a chip off the old block: New research suggests that 2024 PT5 ​​— a small, rocky body dubbed a “minimoon” during its discovery last year — may have been blown off the moon during a giant impact long ago, making it the second known sample traveling near Earth’s orbit. The discovery hints at a hidden population of lunar fragments traveling near Earth. “If there were only one object, that would be interesting but an outlier,” Teddy Kareta, a planetary scientist at Lowell Observatory in Arizona, said…

James Webb Space Telescope finds coldest exoplanet ever seen, and it orbits a dead star

NeRD

Astronomers using the James Webb Space Telescope (JWST) have detected the first planet seen orbiting a dead star, offering new insights into how planets evolve during the final stages of a star’s life. The James Webb Space Telescope‘s observations of the exoplanet, named WD 1856+534 b, also confirm it is the coldest exoplanet to date, which could pave the way for the first detailed atmospheric studies of gas giant exoplanets and help us contextualize our solar system on a cosmic scale. “We were all a bit surprised — and excited…
