Well, did you hear the big news? Life on Venus. Life… on... Venus. Now, where have we heard this before? Oh right, life on Mars. If you’ve been watching any of my videos or listening to Astronomy Cast, you’re cautiously optimistic. Skeptical, but hopeful. That’s the right position to take, because buckle up, the internet’s about to run with this news. It’s going to be difficult to figure out what was really discovered, and what this means for the search for life in the Universe. Want to see this video early?

When the Apollo astronauts first landed on the Moon, they couldn’t go far on foot. That’s why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science. Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it’s considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon. 60 fps Apollo Videos from Dutchsteammachine https://www.youtube.com/channel/UCRGEIYuo_HbUR6GhFLeEkPA Want to see this video early?

When the largest stars die, it’s usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it just… vanished? Of course, it could have been dust. It’s always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if that’s the case, is this happening more often, we just didn’t notice it? Want to see this video early?

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.

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.

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.
