You may find this quiz really hard if you're not too into astronomy. Acceleration is defined as a. Here are some tests from spring 2015:. From Sirius to Spica, Canopus to Capella, and Arcturus to Altair, we have a galaxy of stars waiting for you.
The solar system is located in the minor arm Orion, not Sagittarius. Which are the most likely places in our solar system for life to exist aside from Earth of course? Find out now by trying our astronomy quizzes! This is probably because it is easy to do this for the make-up and special effects people, rather than because we think our body shape is likely to be very common in the universe! What is 2 × 10 6 multiplied by 10 -3? The Great Andromeda Galaxy Observations suggest that Andromeda originally formed from a merger about 8-9 billion years ago, and since then it has had close encounters but not collisions with the neighbouring smaller galaxies M33 2-4 billion years ago , M32 and M110. A star as hot as 10,000°C on its suface will be emitting lots of red and blue light as well, so the whole thing blurs to white. ! How fast is the universe expanding? Using this value for the Hubble Constant, the age of the universe is now thought to be 13. This is the edge of our solar system, and it might even overlap with a similar cloud that we assume surrounds the nearest stars to us - so we might even be swapping comets with nearby stars! Usually more expensive than reflecting telescopes 5. Astrophysicists are using a record-breaking computer simulation to learn their secrets, including whether the clusters gave rise to recently observed ripples in space-time. Mountains on the earth's moon.
It is summer in the northern hemisphere, and the Tropic of Cancer is the northern tropic. Newton's first law of motion. The sun gets its energy from core hydrogen fusion. What are degrees, arcminutes, and arcseconds and how many of which fit into what? By rare coincidence, it has no net spin at all. Which came first, the black hole and the galaxy forms around it or the galaxy and the black hole forms within it? As you might be able to guess, there really isn't an answer to this one or if there is somewhere in the world of theoretical physics we probably wouldn't be able to work out what the sums meant. Light and Telescopes Who first used the telescope to look at planets? So we need to look at places that might still have liquid water, and outside of the Earth there are not too many of those. In simple language, Kepler's second law means that a.
Tycho Brahe's principal contribution to astronomy was a. The only way to find out is to take it. You may have to click on the blank to activate it before you start typing in your answer. Will there be a time when new stars will stop forming? These objects orbit around in roughly the same flat disc that the planets and asteroids do, around the equator of the Sun. The Orion nebula with young stars hidden in the gas and clouds. Space is an amazing place, from our own solar system to the outer reaches of the galaxy.
Furthermore, you notice that this fixed point is 30 degrees above the horizon. There is only one correct response for each question. Early accretion of icy bodies Solar nebula Solar wind Late comet and asteroid impacts Which structural layer of earth is liquid? Why do stars twinkle but planets don't? Telescopes have significantly changed over time. Mercury, Earth, Mars, Venus c. Space Quiz Space is a mysterious place but there are plenty of things we are sure about when it comes to that vast space that surrounds us here on earth. When we look out at distant galaxies, they are all rushing away from us, and the further away they are, the faster they are moving - this is some of the evidence that makes us think everything started in a Big Bang. The earth's orbit is elliptical and therefore its orbital speed varies slightly.
The sun's path ecliptic and the celestial equator cross at the equinoxes. Try answering the twenty questions on your own and then scroll down to the bottom of the page for the all important answers. In fact - the temperature that you need to get green light is about 10,000 degrees Celsius. Don't include this in an essay! Being me, I just had to make one. The disc is out beyond Neptune which means that they take a few hundred years to complete and orbit. Therefore, not all of these questions will apply perfectly to your exact situation.
How much energy would be produced by the total conversion of 1 kg of material into energy? Interacting galaxies often display tidal tails - streamers of stars, gas and dust dragged free of the parent galaxy. Find answers to your , as well as about the other planets in the solar system, stars, and galaxies. They reached the ground at the same time because a. Test your knowledge of planets, stars, moons, astronauts, our solar system, galaxy and more space related trivia. And there are only 50 billion galaxies? The Cartwheel Galaxy is a particularly spectacular example of a nearly centre-to-centre collision, resulting in the nucleus being stretched open like an expanding ring. Are you a trivia star? Mercury, Mars, Earth, Venus d. An astronomer takes a high resolution spectrum of a nearby star and finds that a spectral line normally seen at 5000 â„« appears instead at 5005 â„«.
What possible stellar remnants are left after the explosion? We are in the Orion arm and we are in the virgo cluster. Think about those truly mind-boggling gaps and you start to see that stellar collisions will actually be rare events. Newton's third law of motion. There is far more and around 2. Inner Planets What causes the aurora borealis and aurora australis? This full-scale model of the James West Space Telescope is as big as a tennis court and as tall as a four-story building c This means it will show us some of the first galaxies that existed - although these babies are 300 million years old. We think there are some larger objects out in that region too, like the dwarf planet Pluto - we call these Kuiper Belt Objects not a very imaginative name! What does the central star become after a few tens of thousands of years? What happens when two galaxies collide? For a star to look green to us it would have to emit only green light, and that's impossible for a gigantic ball of burning gas! You may find this quiz really hard if you're not too into astronomy. A snapshot of the oldest light in our Universe from 380,000 years ago showing regions of slightly different densities seeds of all future structure including the stars and galaxies of today.
A collection of older questions below are arranged in categories: sky behavior and astronomy history, light and telescopes, inner planets, outer planets, comets and asteroids, the sun, stars, galaxies, cosmology, and life in the universe. Where am I likely to find globular clusters? Using it's array of instruments it will be able to see infrared light which was emitted by galaxies about 300 hundred million years after the Universe was created in the Big Bang which scientists think was 13.

Discover the difference and evidence for dark energy and dark matter, and learn about worlds closer to home such as Venus and Saturn. Cepheid variable stars are important distance indicators because 1 they are supergiants and thus visible for many Mpc, well into the realm of galaxies, and 2 measurement of the apparent magnitude gives the pulsation period of the star. Diurnal motions are caused by a. In the end though, the idea of a white hole comes out of certain mathematical equations. But if we include dead stars into this question, then a white dwarf star the sort of thing that the Sun will eventually evolve into might only be the size of the Earth 10-15,000 km in diameter , whilst a neutron star would be more like 20km in diameter - and yet could still contain twice the mass of the Sun!
