IN BRIEF

The day the universe grew • Edwin Hubble’s observations showed us that the Milky Way is not all that there is.

SHADOW Science • As the Moon’s shadow crossed the Earth last year, researchers mounted intensive campaigns to study every aspect of the dramatic event.

Expanded roles for citizen scientists

Future Martian invasion?

Pioneer of a NEW astronomy • He’s largely forgotten, yet John Bolton founded a new type of science and probably should have been awarded the Nobel Prize.

To catch a falling star • Improve your chances of success by observing during an annual meteor shower.

The Moon Mess • A planet-scale smash created Earth’s satellite. But how did it come to be so like Earth?

Planets and Moons side by side • The Moon is the fifth-largest natural satellite in the Solar System, both in size and mass — even outranking Europa and Triton. In comparison with the giant planets that host the other large moons, though, Earth is puny. Worlds are shown to scale by radius. Sizes and mass ratios are rounded to the nearest 10.

`Oumuamua’s Dramatic visit • The space rock from beyond the Solar System has left us amazed and perplexed.

USING THE STAR CHART

A peek behind the curtain

The Sea Goat in the sky • The ancient constellation Capricornus has an interesting history.

An early evening blockbuster • Mercury, Venus, Mars, Jupiter and Saturn all share top billing this month.

Orionids by moonlight • The lunar glow will affect this month’s best meteor shower.

SKY PHENOMENA

Voyage through the Telescope • Aptly named southern constellation is home to some pleasing doubles.

Spring’s comet collection • There’s plenty of comet action in the southern sky during October.

A nod to lunar libration • Every month, the Moon’s face wobbles enough to give you a peek at some of its hidden farside.

Square galaxies • Spend some time hunting this group of faint fuzzies in the Great Square of Pegasus.

Giants walk among the stars • Uranus and Neptune are ideally placed for viewing in the evening sky.

Maroon Moon • The Moon turned red on the morning of July 28, as it slid into the Earth’s shadow for the longest lunar eclipse of the century.
