Through the holidays, many people head away from the bright city lights to go camping.

Key Points: 
  • Through the holidays, many people head away from the bright city lights to go camping.
  • As a child, I loved such trips, and they helped cement my passion for the night sky, and for all things space.
  • One of my great joys as an astronomer is sharing the night sky with people.

Learning the night sky

  • A good place to start if you’re a budding astronomer is to learn your way around the night sky.
  • Today, there are countless good apps to help you find your way around the night sky.
  • A great example of such an app is Stellarium – a planetarium program allowing you to view the night sky from the comfort of your room or to plan an evening’s observing ahead of schedule.
  • To memorise the night sky, you can try star hopping.
  • By star hopping, you’ll slowly but surely learn your way around the night sky until the constellations become familiar friends.

Virtual observing

  • Thankfully, software like Stellarium can give you a fantastic virtual observing experience.
  • Imagine you want to see Saturn’s rings – a spectacular sight through even a small telescope.
  • A virtual observing session is as simple as that – just pan around the sky until you find something you want to see, and zoom in.

A hobby best shared

  • I’d recommend using planetarium programs like Stellarium to figure out what you want to see, then heading out to look at it with your own eyes.
  • Astronomy is a wonderful hobby, and one that is best shared.
  • I joined my local astronomy society, the West Yorkshire Astronomical Society in the United Kingdom, when I was just eight years old.
  • At the society, we had weekly talks on astronomy, given by the club members and visiting astronomers from local universities.
  • We also had regular night sky viewing nights, using the society’s very own telescope – a behemoth the members had built themselves.
  • People who are passionate about their hobby love nothing more than sharing it with others.

How do we know the age of the planets and stars?

Key Points: 
  • How do we know the age of the planets and stars?
  • – Swara D., age 13, Thane, India
    How do we know the age of the planets and stars?
  • Planet properties like temperature are often set by the star they orbit rather than their own age and evolution.

Sussing out a star’s age

    • With very accurate measurements, astronomers can compare these measurements of a star to mathematical models that predict what happens to stars as they get older and estimate an age from there.
    • Over time, their spinning slows down, similar to how a spinning wheel slows down when it encounters friction.
    • A steady decline in magnetic activity from a star can also help estimate its age.

Piecing together a planet’s age

    • As natural clocks, radionuclides help scientists determine the ages of all kinds of things, from rocks to bones and pottery.
    • Similarly, soil brought back from the Moon during the Apollo missions had radionuclide ages of up to 4.6 billion years.
    • Although studying radionuclides is a powerful method for measuring the ages of planets, it usually requires having a rock in hand.
    • We cannot yet directly measure the ages of planets outside our solar system with current technology.

How accurate are these estimates?

    • Astronomers believe planets are roughly the same age as their host stars, so improving methods to determine a star’s age helps determine a planet’s age as well.
    • By studying subtle clues, it’s possible to make an educated guess of the age of an otherwise steadfast star.
    • We won’t be able to answer every question, but we will do our best.
