The Hubble Constant tells us how fast the universe is expanding. However, different methods of measuring the Hubble Constant give different results. In this podcast, NOIRLab’s John Blakeslee describes data his team has collected to help resolve this discrepancy.
What is a vacuum, and what makes a false one? What happened in the early universe to bring about our current physics? Will it happen again? If so, when?
Today Cosmic Savannah talk with Sambatriniaina Rajohnson about her work on large scale structure of the universe and her plan to observe these structure in Vela supercluster region using MeerKAT.
How long did the Universe take to complete the periodic table? Is Interstellar travel really out of the question? @CheapAstro will answer these questions today.
In this week’s @cosmicsavannah, Robbie Lees chat with Liantsoa Finaritra Randrianjanahary about the evolution of the universe and how he can determine some of the hidden secrets of the universe
This week we wanted to give you a basic physics lesson. This isn’t easy physics, this is a lesson on the basic numbers of the Universe. Each of these numbers define a key aspect of our Universe.
This week we’re going to talk about famous stars. We’re talking about those hot balls of plasma across the distant Universe. #365DyasOfAstro
Is our universe a fractal? How do we test this? Are there any places in the universe that look like fractals?
It’s been a while since we checked to make sure the Universe was still expanding. Yeah, apparently, that’s still a thing. But in the last few years powerful new telescopes and expansive surveys have given us much more knowledge about what’s happening. Especially at the earliest times.
How did the universe begin? How will it end? What’s going on in here and how did we learn all this? I discuss these questions and more in today’s Ask a Spaceman!
