Summary

TLDRThis video delves into exciting scientific discoveries about Earth's core and Mars' volcanic activity. Researchers have found that Earth's core might hold vast amounts of hydrogen, possibly from water on ancient Earth. Meanwhile, on Mars, a recently discovered volcanic site may have erupted just 50,000 years ago, suggesting volcanic activity could still be happening. The video also promotes Patrick Olsen's new song 'Like This,' a relaxing track from his 'Music for Scientists' album. The single encourages mindfulness and is available on all streaming platforms.

Takeaways

  • 💿 Patrick Olsen's new song 'Like This' is now available on all streaming platforms.
  • 🌌 Hydrogen is the most common element in the universe, but it's rare on Earth's surface.
  • 🧪 New research suggests that Earth's core may contain enough hydrogen to form 70 new oceans.
  • 🪨 Earth's iron core is lighter than expected, indicating lighter elements like hydrogen might be present.
  • 🔬 Researchers used extreme pressure and heat simulations to show that hydrogen could bond with iron in the core.
  • 💧 This hydrogen likely originated from water molecules on early Earth, requiring a vast amount of water to explain.
  • 🌋 A possible active volcanic site has been discovered on Mars, located in Elysium Planitia.
  • 🔥 The volcanic site may have erupted as recently as 50,000 years ago, which is geologically recent.
  • 🚀 The eruption could have been explosive, launching ash and rock 10 kilometers into the air.
  • 📡 NASA's InSight lander detected seismic activity near the site, suggesting underground magma may still be active.

Q & A

  • What is the primary topic discussed in the video?

    -The video discusses the discovery of large amounts of hydrogen in Earth's core and the potential presence of a recently active volcano on Mars.

  • How much hydrogen is thought to be in Earth's core according to the new study?

    -The study suggests that there is enough hydrogen in Earth's core to form 70 new oceans.

  • How do scientists study the Earth's core if they cannot explore it directly?

    -Scientists study the Earth's core by analyzing patterns of seismic waves, which travel at different speeds through different materials, providing clues about the types of rocks they pass through.

  • Why did scientists previously find it controversial that hydrogen could be in Earth's core?

    -It was controversial because, under normal conditions, hydrogen and iron do not bond efficiently. Although some experiments suggested they might bond under extreme pressure, others did not support this.

  • What device did researchers use to simulate core conditions in the new study?

    -Researchers used a device called a diamond anvil cell to crush microscopic samples under extreme pressure, and they also heated the samples with a laser to mimic conditions in Earth's core.

  • Where do scientists think the hydrogen in Earth's core originally came from?

    -Scientists believe the hydrogen in Earth's core likely split off from water molecules during the early stages of Earth's formation.

  • What recent discovery on Mars is discussed in the video?

    -Researchers may have discovered a previously unknown volcanic site on Mars, located in the Elysium Planitia region, which may have erupted as recently as 50,000 years ago.

  • How does the volcanic site in Elysium Planitia differ from most other Martian volcanoes?

    -Unlike most Martian volcanoes, which erupted billions of years ago, this site may have experienced a more recent and explosive eruption, launching rock and ash up to 10 kilometers into the air.

  • What evidence suggests that Mars' volcanic activity may still be ongoing?

    -NASA's InSight lander recently detected two seismic events near Elysium Planitia, which could indicate that underground magma is still active in the area.

  • Who is Patrick Olsen, and what does his new song 'Like This' focus on?

    -Patrick Olsen is a musician known for his album 'Music for Scientists.' His new single 'Like This' focuses on being aware of our senses and our place on Earth. It is described as a chill, relaxing song.
