This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe.You'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.Subscribe to the Weekly Space Hangouthttps://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcgWatch this episode:https://www.youtube.com/watch?v=nzO-QhBFz04Thumbnail credit: ESO/M.

Earlier this year, NASA announced 4 new Discovery-class missions that they were considering. These are low-cost, rapidly-built missions that will help scientists understand some mystery in astronomy and planetary science.One of these missions is called Trident, and it’s going to be targeting the Planet Neptune. And more specifically, it’s going to be providing close up pictures of its largest moon Triton.Want to see this video early?

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of.That’s why it’s reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone.Thumbnail credit: NASA/Harvard-Smithsonian Center for Astrophysics/D.
