Discovery Bonus Points. Not really a discovery, but I think the most amazing astronomical objects I have ever seen has to be Comet Hale-Bopp followed by Comet Hyakutake. Both comets filled the dark rural skies in my home near Ottawa, Ontario. Both filled me with awe -- an awe that I c...
How do dark comets differ from normal comets? Comets, often described as the Solar System’s “dirty snowballs”, are icy bodies made of rock, dust and ices. These relics of the early Solar System are critical to unlocking key mysteries ar...
Right now, six of the seven planets — not including Earth — are visible to the naked eye. If you can get away from the city lights and if it's not too cloudy, tonight you will be able to look up and see Venus, Mars, Jupiter, Saturn, Uranus and Neptune. You can add Mer...
Mercury, Venus, Mars, Jupiter and Saturn are visible with the naked eye, and have been known throughout human history. Following the invention of the telescope in the 17th century, Uranus (which astronomers generally pronounce with the stress on the first syllable, not the second) was discovere...

(clusters, nebulas and galaxies) are restricted to the 222 brightest ones observable using a small, backyard telescope. Only the main solar system objects, and the brightest asteroids, comets and satellites, are included. The new "Tonight at a glance" and satellite notifications are included too...
Plotting the two comets' trajectories over the period APR-1 to APR-30 on the two years forms an almost perfect cross. They intersect between the eyes of the Medusa head that Perseus is holding in his left hand. "Algol" means "Demon Star" in Arabic. The head is known as Rosh Satan (...
The stark difference in size explains why dark comets lack the bright, visible tails of their larger, more iconic counterparts. (Composition: Dr Kirsten Banks; Background image: R. Wesson/ESO; Dark comet: Nicole Smith/Universit...
What you saw were most likely fireball meteors, housewife. There are no naked-eye comets, which are quite rare, currently visible. In addition, unlike meteors, comets move slowly across the sky. https://www.cometchasing.skyhound.com/ ...
