Mr Dobson and his radical idea

Australian Sky & Telescope

NEWS NOTES

Baily and his beads • Francis Baily is remembered for a sole phenomenon, while his other achievements have been somewhat eclipsed.

A LOT IN A NAME

Rugged Worlds • The two spacecraft sent to Ryugu and Bennu have unveiled asteroids with formidable surfaces and mysterious histories.

ASTEROID PROSPECTING?

Revising the story of planet formation • New technology has given astronomers access to the dusty regions where planets are born — and has complicated our picture of planet formation.

How protoplanetary disks form

Venus is dead. Long live Venus. • In which I attempt a contrarian argument against my own contrarian argument.

Quicksilver astronomy • Forget lenses and aluminising — some astronomers are turning to whirling dishes of mercury to study the universe.

What came before

The classic Dobsonian telescope • A relic of the 1970s finally sees the light.

The Dobsonian Mount

USING THE STAR CHART

Blind spot stargazing

Fabled females and a first transit • Constellations that invoke mythological women are found in May’s night sky.

VISTAS

Jupiter and Saturn’s close double act • While Venus vanishes from the evening sky, the two gas giants snuggle up.

The Etas for early risers • This shower is usually a crowd-pleaser.

SKY PHENOMENA

LUNAR PHENOMENA

Two enigmatic comets • These ‘dark horse’ comets are surprising astronomers.

Expect an explosion • T Coronae Borealis is a supernova waiting to happen.

The Mountains of Mitchel • How to glimpse these enigmatic features on the surface of the Red Planet.

Hoag’s legacy • Ring galaxies are among some of the quirkiest objects in the sky — and one in particular piqued the author’s curiosity.

CELESTIAL CALENDAR

Solar eclipses throughout the Solar System • Total solar eclipses are amazing spectacles, but can they be seen from planets other than the Earth?

Changing of the guard • CMOS is set to become the dominant scientific-imaging medium — but is it up to the task?

NEW PRODUCT SHOWCASE

Magna Carta of modern physics • THE GENERAL THEORY OF RELATIVITY

Canon’s mirrorless EOS Ra • We test Canon’s EOS R mirrorless cameras, including the new ‘Ra’ model made for astrophotography.

Canon’s premium RF lenses • Along with the R cameras, we received samples of two of Canon’s premium RF lenses made for the EOS R cameras and ideal for astrophotography.

A ‘painted’ telescope • Here’s how to fabricate a carbon-fibre tube.

Cloudy skies as coronavirus bites • Several astronomy events have had to be cancelled.

2020 CALENDAR
