“How far can you see?” is one of the most common questions I get asked when showing someone the night sky.
And during November, we are perfectly placed to answer this question. The Great Andromeda Galaxy (M31), located low in the northern sky is the farthest object we can see with the naked eye. It is the closest of the large galaxies and contains approximately two hundred billion stars, about as many as our own galaxy. You can see it as a faint smudge of light away from city lights.
The light from the Andromeda Galaxy takes over 2 and a half million years to complete its journey to the earth. Just think about that. The light from the Andromeda Galaxy had already been travelling for a million years before the very first hominids roamed across the plains of east Africa.
By the time the very first ancestors of modern man started making stone tools in China and Africa, the light had completed over 85% of its journey. Travelling at 300,000 kilometres per second, the light raced across intergalactic space to the Milky Way galaxy. When the slaves of Egypt built the great pyramids 5000 years ago, the light from Andromeda was already well inside our own galaxy.
Almost 2800 years ago, Chinese astronomers observed an eclipse of the Sun. They would have also known of that little smudge of light in the night sky but would have been totally unaware of what it represented.
The Greek and Roman empires rose and crumbled; Christopher Columbus discovered the West Indies; and Galileo pointed his first telescope to the heavens. Still that light travelled. By the time Neil Armstrong walked on the Moon in 1969, only 57 years remained of its journey.
The other fun fact to remember is that the Andromeda Galaxy is getting closer to us, by about 400,000 kilometres every hour!
For more than a decade, in fact, it looked like the two galaxies were on a collision course. But recent studies say there’s only a 50-50 chance of a collision and merger. And if it does happen, it’ll take place billions of years later than previous estimates.
The new study used years of observations by two space telescopes – Hubble and Gaia. Researchers plugged those observations into simulations that also considered the gravitational effects of two smaller galaxies. The results indicated that one of them tends to push Andromeda and the Milky Way together, while the other tends to pull them apart.
The researchers ran a hundred thousand simulations. In half of them, Andromeda and the Milky Way flew past each other and went their own ways. In the other half, they eventually spiralled together and merged – but not for at least 10 billion years – twice as long as earlier estimates.
The simulations aren’t the final word, as there are just too many uncertainties. But for now, it seems likely that the two giants will stay apart for a long, long time. Phew!!! That’s a relief. I hated the new name that that been proposed for the combined galaxy – Milkomeda!!
So, when you next go out on a clear November night and look at that smudge of light that we know as the Andromeda Galaxy, try to imagine that immense journey and all the history that has passed since that light began its journey to Earth.
Rising in the east late into the evening, we can now see the constellations that will keep us company during the warm summer nights. Orion, the mighty hunter of Greek legends is the best known. Stars like Sirius, Rigel, Betelguese and Aldebaran bring a formidable brilliance to the eastern sky which is not repeated at any other time of the year.
Another sign of the coming of summer is the appearance of the Pleiades star cluster in the north-eastern sky. Probably better known by its more common name of “the Seven Sisters”, the cluster marks the shoulder of Taurus, the bull.
The Pleiades is actually a cluster of several hundred young stars. It's about 400 light-years from Earth. If we were orbiting a star embedded in the Pleiades, and looking back toward our own solar system, the Sun would be invisible. It's just too faint to see from that far away. But many of the stars of the Pleiades are hotter and brighter than the Sun, so they're easy to see.
Long-exposure photographs of the cluster show that the stars are surrounded by wisps of gas. The gas shows up because it reflects light from the stars.
Astronomers used to think this gas was left over from the formation of the cluster. But over the last decade or so, they've come to realize that the stars are just passing through the gas cloud, so there's no real relationship between them.
Look high in the northern sky and you’ll find beautiful Saturn. It’s height above the horizon means that atmospheric turbulence will be at a minimum ensuring crisp views of the planet and its magnificent rings.
It’s pretty easy to measure the length of a day on Mars or most other solid bodies. Just pick a feature on the surface and see how long it takes to spin back into view. That’s not the case for Saturn though. It’s not so easy for planets that don’t have a solid surface. We can track bands of clouds, but different bands can move at different speeds.
Scientists have been trying to pin down Saturn’s rotation rate, the length of its day, for centuries. When the twin Voyager spacecraft flew past Saturn in the 1980s, they measured the planet’s magnetic field to reveal the rotation rate of its interior. But when the Cassini spacecraft orbited Saturn decades later, its observations showed the day was about six minutes longer.
At the end of its mission, Cassini flew between Saturn and the inner edge of its rings. Measuring waves in the rings and tiny changes in the planet’s gravitation field produced yet another length: 10 hours, 33 minutes, and 38 seconds.
One thing you’ll notice when observing Saturn, if you can bear to move your gaze away from the rings, is that the ball looks flattened at the poles. It is 10 percent wider through its equator than through the poles. A result of its low density and fast rotation.
Saturn consists of a series of layers. Its core is a dense ball of metal and rock. Around that is a layer of hydrogen that’s squeezed so tightly that it forms a metal. Around that is a layer of liquid hydrogen, the lightest and simplest chemical element. And the planet is topped by an atmosphere that contains methane, ammonia, water, and other compounds.
Saturn doesn’t have a solid surface. But scientists have defined a “surface” as the depth in its atmosphere where the pressure equals the surface pressure on Earth. At that level, Saturn’s gravity is only a bit stronger than Earth’s gravity. If you were floating at that altitude, you’d feel like you’d added a few kilograms. And because of Saturn’s flattened shape, you’d feel heavier at the poles than the equator.
The Moon is at Last Quarter on November 2, New on the 9th, at First Quarter on the 17th, and Full on the 25th.
Happy stargazing.
