Galaxies Were Already Dying Just 700 Million Years After the Big Bang

When galaxies run out of primordial hydrogen and helium, they cease star formation, shifting to primarily long-lived red stars. These galaxies are considered "red and dead." It usually takes billions of years for galaxies to run out of hydrogen, but now astronomers using JWST have found examples of galaxies that have already stopped forming stars just 700 million years after the Big Bang, much earlier than predicted by cosmological models. from Universe Today https://ift.tt/l3HPVM9 via IFTTT

Perseverance is Trying Out Spacesuit Materials on Mars

NASA's Perseverance Rover is an ambitious mission. Along with its day-to-day exploration, the rover carried an experimental rotorcraft and is also caching samples for eventual return to Earth. But there's another aspect to its mission that's hidden in the glare of its ambitions. The rover is busy testing five different spacesuit materials. from Universe Today https://ift.tt/G4XP0wT via IFTTT

Students Designed a Mission to Venus on the Cheap

Sometimes, the best way to learn how to do something is just to do it. That is especially true if you're learning to do something using a specific methodology. And in some cases, the outcome of your efforts is something that's interesting to other people. A team from across the European Union, led by PhD candidate Domenico D'Auria, spent a few days last September performing just such an exercise - and their work resulted in a mission architecture known as the Planetary Exploration Deployment and Research Operation - Venus, or PEDRO-V. from Universe Today https://ift.tt/kYU35aV via IFTTT

LOOKING GLASS: Exploring Titan's Icy Hydrocarbon Cycle

Though wildly different in so many ways, Earth and Saturn's moon Titan have something important in common. Among all the objects in the Solar System, they're the only two with liquids on their surfaces. There are parallels in how the liquids move in cycles on both worlds and a new mission proposal outlines how we can understand Titan better by studying these parallel processes. from Universe Today https://ift.tt/Eexv06Q via IFTTT

Black Hole Found Consuming its Own History

One of the common misconceptions about black holes is that they devour not only matter, but also the history of that matter. So when a black hole forms, you can only guess how it came to be. That isn't entirely true. Informational history is only lost when matter crosses the event horizon, and perhaps not even then. The material surrounding a black hole still has a rich history. In a recent study, astronomers have used that history to uncover the origins of a black hole system. from Universe Today https://ift.tt/GzbyTJS via IFTTT

Venus Could Be Much More Volcanically Active Than We Thought

Even though Jupiter's moon Io is considered the most volcanically active world in the Solar System, Venus actually has more volcanoes and volcanic features on its surface. For a long time, scientists thought that most of these features and volcanoes were ancient remnants of the planet's geological past. However, newer research shows that Venus is still volcanically active. from Universe Today https://ift.tt/kcwxtM3 via IFTTT
