Questions & Answers

Q: How was the closest black hole discovered?

The closest black hole was found using x-ray transients in a binary system where the black hole was siphoning material off a star, emitting x-rays.

Q: How long can bacteria survive underground on Mars?

The dinococcus radio Durant bacteria can survive under Mars' soil for approximately 280 million years due to its radiation resistance.

Q: How can Starlink's satellites serve as a GPS system?

By decoding timing bits from Starlink satellites, researchers at the University of Texas Austin were able to reverse engineer location on Earth with 30 meters accuracy.

Q: Why won't Arecibo Observatory be rebuilt?

The Arecibo Observatory won't be rebuilt after its collapse in 2020 as the National Science Foundation will focus on other projects and build a science center instead.

Summary & Key Takeaways

• Closest black hole found in binary system using x-ray transients.

• Bacteria like dinococcus radio Durant can survive under Mars' soil due to its radiation resistance.

• Starlink's satellites can be used as a GPS alternative, opening up new possibilities for navigation.
