CosmicRami<p>Whooooaaaa! The new <a href="https://aus.social/tags/JWST" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>JWST</span></a> image is so good! So much physics going on — physics Einstein himself thought about!</p><p>This is called an Einstein Ring. When a massive foreground galaxy (in this case, an elliptical galaxy) warps the space-time around it, light from behind it bends in our direction.</p><p>The JWST caught this fantastic example, where the background spiral galaxy is getting warped into our view. It appears as a ring, but we can see its structures like its spiral arms, gas features and star clusters. </p><p>Incredible science happening here! </p><p>📸 ESA/Webb/NASA/CSA/G.

pglpm<p>Dear geodesists, astronomers, and astrophysicists: Does any of you know of some publication that explicitly reports the expression for the metric in a Geocentric Terrestrial Reference System (GTRS) or in the more specific International Terrestrial Reference System (ITRS)?</p><p>Various publications (eg <a href="https://doi.org/10.1086/378162" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">doi.org/10.1086/378162</span><span class="invisible"></span></a>) and textbooks (eg <a href="https://doi.org/10.1017/CBO9781139507486" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">doi.org/10.1017/CBO97811395074</span><span class="invisible">86</span></a>) report and discuss the metrics for the Geocentric Celestial Reference System (GCRS), but not for the GTRS.

Debbie Goldsmith 🏳️‍⚧️♾️🇺🇦⧖<p>I keep seeing the news about lunar time presented as “the Moon is getting its own time zone." What's actually happening is the Moon is getting its own time *standard*. The problem being solved is that time passes slightly more quickly on the Moon compared to Earth (due to General Relativity) and so the Moon needs its own time standard for precise measurements and navigation. UTC is the time standard for measuring time on Earth, and LTC is being created for the Moon.</p><p><a href="https://mastodon.social/tags/GeneralRelativity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GeneralRelativity</span></a> <a href="https://mastodon.social/tags/time" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>time</span></a></p>
