Episode 711: The Universe in Formation. Hubble Sees 6 Examples of Merging Galaxies
6:27
10 billion years ago, galaxies of the Universe were ablaze with the light of newly forming stars. This epic phase of history is known as β€œCosmic Noon” - the height of all star creation. Galaxies like our Milky Way aren’t creating stars at nearly the rates they were in the ancient past. However, there is a time when galaxies in the present can explode with star formation – when they collide with each other. This recently published collage of merging galaxies by the Hubble HiPEEC survey (Hubble imaging Probe of Extreme Environments and Clusters) highlights six of these collisions which help us understand star formation in the early Universe.

In this week's Open Space, we had a series of questions about the International Space Station. How long will it remain in orbit, and what role will it continue to play with other space stations under construction? We also talked about how much longer the Earth will remain habitable, and if it could be possible to replace Arecibo. 00:00:00 Start 00:03:35 How much longer with the Earth be habitable? 00:06:30 The great conjunction 00:09:11 Is nuclear power a good option in space? 00:13:31 What is the future of the ISS? 00:18:24 What are the chances of replacing Arecibo? 00:21:57 Couldn't we melt down the station for raw material? 00:23:35 What do I think of Axiom's private space station? 00:27:28 What's the best supernova candidate? 00:32:25 Could we add mass to Mars to restart its core? 00:36:03 Am I excited about the next Gaia release? 00:40:45 Are we looking backwards in time? 00:42:00 How's Chinese going? 00:46:39 What's the future of the Thirty Meter Telescope? 00:50:24 Will there be more international collaboration? 00:54:45 How much of the Universe has already disappeared? 00:56:33 Future telescope names? 00:57:00 Legit warp drive? 00:59:45 Any value putting a telescope on Mars?

Episode 688: Remnants From the Early Universe. Primordial Black Holes
12:55
Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, you’d still end up at the singularity. Astronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well. But there’s a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter. Primordial black holes.

Episode 682: Life on Venus? A Key Biosignature Called Phosphine has been Discovered in Venus' Atmosphere
10:38
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?

Episode 676: Lunar Rovers. From Apollo to Artemis
10:16
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?

Episode 674: A Massive Star Just Disappeared. No Supernova, Just Straight to Black Hole
9:04
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.
