Will we recognize alien life if we find it?
In searching for life on other planets, including on planets orbiting other stars (exoplanets), we are faced with some serious problems. In the case of...
A close encounter with the Sun
In December, the Parker Solar Probe spacecraft made the closest controlled approach to the sun of any manmade object. Moving at 192 kilometres a second, it was...
Light from one of first galaxies to form after the beginning of the universe finally seen
Once again the James Webb Space Telescope has come up with a stunning and intriguing image. Taken with some major cosmic help, it shows one of the first...
Astronomy from a logging road
There are some astronomy projects that are better done far away from observatories, or any other form of human activity. The enormous amount of interference...
The quest for a Martian calendar
In a few days, on the Dec. 21, the Earth will reach the point in its orbit where the northern end of its axis is leaning directly away from the Sun. We will...
The rings of our solar system's most distinctive planet
These evenings, when it is clear, there is (what appears to be) a fairly bright yellow "star" in the southern sky. It is not actually a star; it is...
Measuring magnetic fields in space
Every week, the Dominion Radio Astrophysical Observatory (just south of Penticton) has a science meeting, where, after all the interesting admin updates are...
Looking back to see how astronomers of the past worked
Our ancestors had no problem with the idea that the sun would rise and set every day, providing light and warmth, forever. Things in the sky things could be...
When it comes to galaxies, it's a case of eat or be eaten
Looking at the summer Milky Way on a clear, dark night from the shore of a lake is a wonderful experience. It all looks so beautiful and peaceful. The images of...

A number of countries are preparing to send astronauts to the Moon. It is likely, this time the missions won't just be flying visits but part of the work...
How we learned to figure out exactly where we are at any given time
These days, thanks to GPS (global positional systems), it is easy to know exactly where you are. Until quite recently, that was not always the case. Knowing...
Death and life in the solar system
Corona Borealis, "The Northern Crown,” is one of those rare constellations that actually looks like what it represents. It is a small circlet of...
Underground installations help us 'see' what's reaching us from space
We put optical observatories on tops of high mountains to get them above the clouds and away from our light pollution. Radio observatories are usually put in...
Advancement in telescopes revolutionizing our ideas of how the universe works
The most familiar type of telescope is the refractor. It uses two lenses, one to collect the light and form an image, called the “objective,” and...
Could the inhospitable atmosphere on Jupiter be creating diamonds?
Carbon comes in two forms. One is graphite, which is soft, black, greasy and hard to wash off clothes. It is widely used as a lubricant. Its presence is what...
Looking for a planet called Vulcan
Our ancestors noticed that among the "fixed” stars, which remained in unchanging patterns, there were five "wandering” stars, or planets,...
Protecting Earth from the Suns coronal mass ejections
Seeing the launch of a coronal mass ejection (CME) from the surface of the Sun is an awe-inspiring experience. The story starts with a huge loop, many times...
