A Rover To Mine Martian Volcanoes

Different parts of Mars have different advantages and disadvantages when it comes to their available resources, just like Earth. The polar caps are likely the most valuable in terms of their water content, which will be critical to any early stage crewed mission to the Red Planet. But to really unlock the fully potential of … Read more

Civilization Can’t Arise Without Plate Tectonics And Carbon Dioxide

While plate tectonics may not be absolutely necessary for life, they may be necessary for a technological civilization to arise. Habitability may be possible on a static world, but habitability probably won’t persist long enough for a technological civilization like ours to appear. Plate tectonics regulates our planet’s climate, and without it, atmospheric CO2 would … Read more

Interstellar Objects Like Comet 3I/ATLAS Could Act As Planetary Seeds

The Gemini South Telescope captured this image of the interstellar comet 3I/ATLAS as it sped through the inner Solar System. The comet’s coma and tail are growing as it approaches the Sun.

Astronomers Catch a Planet in the Act of Being Born

Protoplanets are celestial objects in the act of forming into full planets within the gas and dust disks surrounding hot, young stars. These objects, often several times the mass of Jupiter, are still embedded in their birth environments, actively feeding on surrounding material through their own circumplanetary disks. Unlike mature planets, protoplanets offer a rare … Read more

Clusters and Chains of Stars Reveal a Dynamic Milky Way

Three data releases from the recently retired Gaia spacecraft show that far-flung parts of the Milky Way are connected by families of stars born in clusters. Some continue to travel the galaxy together, while others appear wildly dispersed, sometimes as chains of related stars. One cluster is even trying to escape the Milky Way. The … Read more

Does the Multiverse Explain the Nature of the Universe?

One possibility to explain the constants of nature is that there’s more than one universe. That we live in a multiverse, with each different universe “sampling” different values of the constants. There are a few extremely hypothetical ideas in physics that can lead to the multiverse. One is through the concept of eternal inflation, where … Read more
