A tour of Laniakea, one of the biggest structures in the universe

Professor Jim Al-Khalili guides us through Laniakea, a gigantic collection of galaxies in which our home the Milky Way is one tiny dot.

Not everyone on Mastodon may know about my Bright Star Catalogue app. This is a web application that allows you to search for information about any naked eye star from Gaia DR3, Hipparcos and several other sources: https://gruze.org/bsc_app/

Someone asked me for great professional concept/scifi artists to follow on Mastodon. Here are a few:

@ianmcque
@utopieselective
@Robmccallum
@artofsoulburn
@Saltybretzel
@eldritch48
@Ailantd
@alexconnolly
@badgertracks
@alexriesart

Other artists: don't hesitate to wave in comments. I'll do a better list next week :)

any space drive worth it's weight can turn a ship into a missile, Spaceguard must be on constant watch to make sure traffic doesn't deviate suspiciously off course.

Two weeks ago, Canadian #astronaut Dave Williams and I released our latest #book: "Why Am I Taller? What Happens to an Astronaut’s Body in Space."

It's a fun romp through #space and #spacemedicine with a literal space doctor (that would be Dave; I'm a space journalist.) I'd love to see our book appear in more #libraries, so do make a request at your local! Or, if you want a copy, do support your local bookstore. :)

By the time Gaia DR4 is released in 2025 I expect that my virtual starship will have a full range of tools for exploring and presenting the data as a WebXR immersive experience.

The galaxy orbits that we have computed and published in our "Action Dynamics of the Local Supercluster" paper are used in the amazing version 3 of the super popular "Star Size Comparison" video (the vortex version)... Another beautiful job by #morn1415 ! Check out also the featuring of Laniakea ;0)

One thing I like about my new Instagram account is that you understand the subject at a glance.

I wish my Twitter (or Mastodon) homepage looked this nice.

An interesting inclusion on the @RollsRoyce
stand was a graphic of their new gas cooled 1-5MWe microreactor, intended for land and marine applications, which is related to a BWXT-led prototype programme to deliver in 2024 1/2 https://bwxt.com/news/2022/06/09/BWXT-to-Build-First-Advanced-Microreactor-in-United-States
