A dagger from the stars
In 1922, when archaeologist Howard Carter opened up the tomb of the Pharaoh Tutankhamun, the first undisturbed ancient Egyptian royal tomb to be discovered, he...
Globular clusters with hundreds of stars spotted in space
In summer, the constellation Hercules, named after the hero in Greek myths, is high in the sky. The constellation looks like a broad-shouldered, headless man...
James Webb Space Telescope's view of the universe
The James Webb Space Telescope (JWST) continues to make the front pages in astronomy news. One of the latest images is of the planet Uranus, the seventh planet...
The Sun's impact on our solar system is important
In February 2022, a burst of high solar activity caused the loss of a set of Starlink satellites that were in the process of deployment. The solar activity...
Kicking up a lot of cosmic dust
By now most of us must have seen the incredible images produced by the James Webb Space Telescope. Then of course, there are the beautiful images obtained using...
Inhospitable planet only beautiful from far, far away
Venus is one of the most beautiful sights in the sky. That brilliant, white spark in the morning or evening star got it referred to as Phosphorus "The...
Making really big telescopes
As I write this, the biggest radio telescope ever built, and maybe likely to be built for a very long time, is taking shape. Part of it is in Africa and the...
Conjunctions and 'rising worms' in space
On March 2, the planets Venus and Jupiter were within half of a degree of each other in the western sky after sunset. That is closer together than the width of...
Galaxy found with multiple black holes
A distant dwarf galaxy, located some 7.5 billion light years away (which means it is so far away its light is taking that long to get here), has ejected a...
How to make a really big bang
To make a very big bang in space, we need two stars orbiting fairly closely around each other. These so-called “double” stars are really quite...
Too far to fly to the stars
Several thousand planets orbiting other stars have been found so far and some are "Earthlike.” So far, almost all these planets have been found by...
Looking at the origins of the Moon
Around 4.5 billion years ago, the formation of the Sun's family of planets was in full swing. Dust and lumps of rock and ice were colliding and joining...
The threat to Earth by celestial ‘vermin’
On Jan. 26 a tiny asteroid passed Earth, a mere 3600 km away, at a speed of around 9.3 kilometres a second. Known as 2023 BU, it was discovered by Crimean...
Light pollution is stopping us from seeing the night sky properly
We're a funny species. On one side, we like to lie on our backs by lakes in the woods, or at other dark places, and enjoy looking at a starry sky. Poets,...
The age-old question: Is there life on other planets?
One of the planets being studied with the James Webb Space Telescope is about the size of the Earth. However, it lies so close to its star that it only takes...
Hisses, whistles and clicks—the sound of the magnetosphere
Quite a few years ago now, an ionospheric physicist and I were a long way up a dirt, logging road in Algonquin Park, in Ontario. The idea was to get a long way...
The era of really huge telescopes has arrived
An optical telescope with a mirror 30 metres in diameter is being built. Also under construction is the largest radio telescope in history. This need for...
Listing the faint ‘fuzzies’ in space
Comets are among the most beautiful sights in the night sky. For a few weeks maybe, they grace the sky before vanishing again. We see a glowing head followed by...
Astronomical highlights of 2022
In this last article of 2022, it seems appropriate to mention two of the most exciting things in astronomy that happened this year. The first is the successful...
