The Andromeda Galaxy Find it by looking high in the east between 8 and 10 o'clock. Find the Andromeda, the Princess, and her string of three medium bright stars.
Use the middle star, and then follow two fainter stars to the upper left, where you'll see a faint smudge of light. Looking slightly away from it allows the light to hit a more sensitive part of your eye, and you will see it more easily, though still quite faint. November 11, Select Date of Nightly Events.
If you want to see Uranus or Neptune you need to use a telescope. The 8 planets of our Solar System all orbit the Sun at different speeds. This means we see the planets at different times each year. Astronomers use their knowledge of the movements of planets to predict where and when they will be visible in the night sky. The ' Horizon View ' pictures show maps of the night sky for each of the compass points: north, east, south, west.
Make sure to note down which map the planet appears in before you go looking for it. The ' Whole Sky ' pictures show the entire sky as a big round picture. But this successful deployment was followed by two nail-biting weeks as people on the ground were unable to receive any communications from the satellite.
They finally detected signals late in the month and are now working hard to get the satellite up to full capacity. Image: What a view! Binar-1 is too small to be seen from the ground with your eyes, but you can track it down if you are a keen radio enthusiast and it is on a similar orbit to the International Space Station.
You can use this website to help you figure out the best time to see the ISS passing overhead. Satellites in low earth orbit like the ISS and Binar-1 move more than 7km per second. Venus is looking glorious in the western sky in the evenings. Because of the way the orbits line up , it is backdropped by the centre of the Milky Way in Sagittarius right now, and in the first week of November its path will take it almost right through the middle, as seen from Earth.
This is of course an observational effect, the black hole itself is 26, light years away, but you can use Venus as a reference point. Jupiter is still looking nice and bright, high in the evening skies. It reaches eastern quadrature on 15 November, which means at sunset on this date it will lie exactly along a line drawn north to south in the sky.
Seen from above, lines drawn from the Sun to Earth and from Earth to Jupiter will meet at a right angle. Another way of thinking about this is if you point one hand at the setting sun and the other at Jupiter, your arms will make a right angle. Aries is a medium-sized constellation and part of the Zodiac, meaning that it lies along the ecliptic which you will be able to trace out using the instructions above. It is visible in the northern sky in the mid-evenings during November, and is recognised as the gently curving set of stars representing the ram and its horns.
The brightest star in this constellation is Hamal, a giant star that has used up all the fuel in its core and is now in the process of fusing hydrogen in layers around the middle. The location of fusion away from the core of the star causes its outer layers to heat up and expand, and ultimately cool the star down a little, turning it a reddish colour.
The ram appears in many stories of mythology, perhaps the most well known being the bearer of the golden fleece which was made from its hide, serving as the basis for one of the trials of Jason and his crew of Argonauts. This story is also recorded in the gigantic asterism of Argo Navis, these days broken into the constellations of Vela, Puppis and Carina — visible in the south east at the same time as Aries is up in the north. Always guaranteed to get a lame laugh, this planet gets its name from the primordial Greek God of the Sky.
It should appear as a greenish-blue source through a medium-sized telescope. Uranus is technically the first planet ever discovered. The other naked eye planets Mercury, Venus, Mars, Jupiter and Saturn have been known since antiquity, while Uranus is recorded as being discovered on 13 March Its long orbit and great distance from us mean it requires many observations or powerful equipment to see the signs that this point of light in the sky is an entire world.
No matter how, the result is that seasons on Uranus last for decades at a time. The local claim to fame is that observations performed at Perth Observatory helped confirm the discovery of the rings of Uranus. The planet was predicted to pass in front of a distant star and block out the light received. Astronomers noticed that in addition to the expected drop in starlight from the planet being in the way, there were also dips in starlight observed just before and just after Uranus blocked the star: tell-tale signs of a ring system around the planet obstructing the starlight.

It seems like something that belongs in a movie: An asteroid is headed towards Earth — can we deflect it by flying a big heavy spaceship into it to push it off course and save the planet? Taking off on a SpaceX Falcon 9 rocket, it will speed towards the double asteroid Didymos. To be clear, Didymos and Dimorphos are not on a collision course with Earth, we are safe for now.
Asteroids can be tricky to study, and their widely varying composition makes it difficult to extrapolate data from one study to the next. Image: DART. Travelling to an altitude of km, this carries travellers well above the Karman line , the internationally agreed edge of space. You might have noticed that the New Shepard rocket looks a little different to the sleek rockets we have become used to. The reason is in the landing of the rocket and the safety of the people on board.
Landing rockets is a difficult and dangerous task, so if you can make sure there are no people around when it happens, all the better. The crew capsule at the top of the New Shepard is designed to detach and land separately under parachutes as the now uncrewed booster stage lands using its engine. The two separate at an altitude of about km so they have plenty of time to drift apart.
