Scientists find evidence of 'supernova graveyard' at the bottom of the sea — and possibly on the surface of the moon
- Researchers have found evidence of a 'supernova graveyard' in the deep sea, potentially originating from a cosmic explosion called a kilonova 10 million years ago.
- Samples from the ocean revealed traces of rare radioactive plutonium believed to be debris from these cosmic events, which could also be present on the moon.
- The discovery of isotopes like plutonium suggests the occurrence of kilonovas, explosive events spawned by colliding binary neutron stars.
- Scientists aim to conduct further tests, particularly on lunar samples, to strengthen their theories and validate the existence of past kilonova events.
- The Artemis missions, set to return humans to the moon, offer hope for more abundant lunar soil samples for analysis.
- By analyzing additional moon soil, researchers seek to confirm the occurrence, timing, and location of ancient cosmic explosions like kilonovas.
- The moon's geology provides a clearer picture of how cosmic debris settles compared to Earth's more complex environmental factors.
- With upcoming Artemis missions, scientists hope to gain access to more lunar samples to advance their research on cosmic events.
- Fields and his team are working towards proving their theories to the scientific community and making a compelling case for studying these phenomena further.
- The collaboration between research efforts and space missions like Artemis could offer valuable insights into the history of cosmic explosions and their aftermath.

Can any nearby supernova cause a mass extinction
- A nearby supernova can cause mass extinction by breaking up the ozone layer on Earth, leaving it vulnerable to ultraviolet radiation from the Sun.
- The dangerous outputs of a supernova, such as X-rays and gamma rays, can tear apart molecules and cause the formation of nitrogen oxides, including nitrous oxide (laughing gas).
- Without the ozone layer, photosynthetic microorganisms like algae become vulnerable, leading to ecosystem collapse and a mass extinction.
- However, there are no known supernova candidates within 30 light years of Earth, providing a relief from the potential danger.

Why we are so scared of space—and how this fear can drive conspiracy theories
- The fear of space is driven by concerns about asteroid strikes, climate change, wars, and unknown threats from above.
- Daniel Deudney warns that technologies used for planetary defense could also be weaponized in military conflicts.
- Deudney suggests limiting human activities in space to avoid catastrophic conflicts and species extinction.
- Ancient tales like the Cosmic Hunt and modern fears like UFOlogy highlight deep fears about space and human actions.
- Belief in conspiracies related to space, such as UFO cover-ups, stems from underlying fears of space as a threat.
- Chinese science fiction author Cixin Liu likens space to a 'dark forest' where civilizations hide from each other.
- Ground bias leads to viewing space as a threatening external entity rather than part of our interconnected world.
- Fears about space extend to theories like viruses originating from space, as seen in the COVID skeptics' beliefs.
- Wickramsinghe's theory of viruses from space driving pandemics demonstrates how anxieties about space are used to explain earthly phenomena.

Where do meteorites of different types come from?
- Meteorites originate from meteoroids and asteroids in the asteroid belt, with recent research linking them to specific regions within the belt.
- Traced meteorite falls provide a map of the asteroid belt, aiding in planetary defense and asteroid evolution studies.
- Most meteorites come from asteroid families formed by collisions, such as the Koronis and Flora families.
- H-chondrites trace back to the Koronis family, while L and LL chondrites correspond to the Flora and Hertha families.
- Asteroid fragments reaching Earth do so through orbital evolution due to forces like the Yarkovsky effect and resonances with Jupiter.
- Efficiency of resonances like the ν6, 3:1, and 5:2 varies in delivering meteorites to Earth from the asteroid belt.
- Meteorites can have exposure ages indicating long periods within asteroids before being ejected towards Earth.
- Advancements in technology, like all-sky camera networks, have improved tracking of meteorite falls and origins in recent years.
- Efforts to detect more asteroids before impact and refine observations aim to enhance understanding of the asteroid belt's influence on Earth.
