How Many Galaxies Are There?

Clark Planetarium offers classroom resources and lesson plans. In addition, we also offer professional development workshops for teachers. Workshops typically are scheduled through district science specialists and can be taught on-site for a single district or for several districts together. Some workshops can only be scheduled if funding is available, and some may offer resource kits teachers can take back to their schools. E-mail clarkeducation slco. In this training, learn how to demonstrate the phenomena of seasons and moon phases. In addition, learn how to guide students through investigations of the causes. Learn how to act out the motions of the Earth, Moon, and Sun in this active and engaging workshop. Teachers will act as students in modeling the correct motions and appearances of the Moon and Sun in the sky.

Planet 1 orbits the star with period Tl and Planet 2 with period T2. Gravity and Orbits Activity Page 5! Effects of Gravity on Planetary Orbits. Which of these orbits you will be in is determined by your orbital speed Planetary Gravity Obviously, gravity is very important on Earth. Introduction: You will be investigating the role that gravity plays in creating orbital motions, such as those of the planets around the sun.

Galaxies — those vast collections of stars that populate our universe — are all over the place. But how many galaxies are there in the universe? Counting them seems like an impossible task. Sheer numbers is one problem — once the count gets into the billions, it takes a while to do the addition. Another problem is the limitation of our instruments. To get the best view, a telescope needs to have a large aperture the diameter of the main mirror or lens and be located above the atmosphere to avoid distortion from Earth’s air.

The telescope watched a small patch of sky in repeat visits for a total of 50 days, according to NASA. If you held your thumb at arm’s length to cover the moon, the XDF area would be about the size of the head of a pin. By collecting faint light over many hours of observation, the XDF revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.

So if that single small spot contains thousands, imagine how many more galaxies could be found in other spots.

A selection of answers will be published on the page below. In Summer , Hubble passed the landmark of its millionth observation, by making a spectroscopic analysis of the atmosphere of exoplanet HAT-P-7b. Nearly observing programmes have been carried out or are pending since launch in Hubble has a number of instruments on board — essentially, advanced digital cameras — that have been regularly upgraded and replaced during the five servicing missions to Hubble. This is because the camera was made up of four light detectors with overlapping fields of view, one of which gave a higher magnification than the other three.

When the four images are combined together into one picture, the high magnification image needs to be reduced in size for the image to align properly.

ANSTO provides secondary students with a range of learning resources for those interested in science or studying for exams. For teachers, ANSTO provides learning resources and professional development, as well as in-school-term science tours and videoconferences. They can also be used on their own as a classroom resource. The workbooks for our pre Year 12 Chemistry and Year 12 Physics tours are still available for download.

Freely Accessible Remote Laboratories FarLabs have developed a nuclear remote online laboratory that schools can use to perform experiments with nuclear radiation. Students can choose to pair one of four sources alpha, beta, gamma, and unknown with one of five absorbers, including no absorber at all. The “Inverse Square Law” experiment demonstrates how the amount of radiation decreases with increasing distance from a radiation source.

Students can access a live data feed showing the count rate from a Geiger counter placed at a selected distance away from a radiation source. Teacher Registration. FarLabs Remote Laboratory.

How the Universe Works is a documentary science television series that originally aired on the Episode #, Title, Directed by, Original air date. 1, “Big Bang.

At a particular instant roughly 15 billion years ago, all the matter and energy we can observe, concentrated in a region smaller than a dime, began to expand and cool at an incredibly rapid rate. When the universe had expanded an additional 1, times, all the matter we can measure filled a region the size of the solar system. At that time, the free quarks became confined in neutrons and protons. After the universe had grown by another factor of 1,, protons and neutrons combined to form atomic nuclei, including most of the helium and deuterium present today.

All of this occurred within the first minute of the expansion. Conditions were still too hot, however, for atomic nuclei to capture electrons. Neutral atoms appeared in abundance only after the expansion had continued for , years and the universe was 1, times smaller than it is now. The neutral atoms then began to coalesce into gas clouds, which later evolved into stars. By the time the universe had expanded to one fifth its present size, the stars had formed groups recognizable as young galaxies.

When the universe was half its present size, nuclear reactions in stars had produced most of the heavy elements from which terrestrial planets were made. Our solar system is relatively young: it formed five billion years ago, when the universe was two thirds its present size. Over time the formation of stars has consumed the supply of gas in galaxies, and hence the population of stars is waning. Fifteen billion years from now stars like our sun will be relatively rare, making the universe a far less hospitable place for observers like us.

Our understanding of the genesis and evolution of the universe is one of the great achievements of 20th-century science.

But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of “evolution. In the late s the American astronomer Edwin Hubble made a very interesting and important discovery.

Hubble made observations that he interpreted as showing that distant stars and galaxies are receding from Earth in every direction. Moreover, the velocities of recession increase in proportion with distance, a discovery that has been confirmed by numerous and repeated measurements since Hubble’s time.
