Imagine the Universe!
He also made important contributions to mechanics, stating that in a collision between bodies, neither loses nor gains ``motion'' (his term for momentum). In astronomy, he discovered Titan (Saturn's largest moon) and was the first to correctly identify the observed elongation of Saturn as the presence of Saturn's rings.

The Sun gives off different kinds of energy: including heat, visible light, and invisible light in the form of ultraviolet (UV) rays. While the Earth's atmosphere protects us from most of the Sun's harmful UV rays, there is still an abundance of UV rays around us. This activity explores UV rays from the Sun and ways we can protect ourselves from these potentially harmful UV rays.

Exploring Magnetic Field Lines
When discussing space weather or how Earth's magnetosphere protects us, we often see diagrams with lines wrapping around the globe. What are these lines? Can we see these lines if we were in space looking back at Earth? This activity lets us explore the magnetic field of a bar magnet and serves as a good introduction to understanding Earth's magnetic field. It is also a good way to demonstrate why prominences are always "loops".

Eclipse: How can the little Moon hide the giant Sun?
Although this activity isn't a "make and take", it offers great hands-on exploration of how distance can affect the way we perceive the size of an object. It makes a good introduction to solar eclipse as well as Sun and Moon's sizes and distances from Earth. The idea behind this activity is very simple and the activity itself is easy to do, making it accessible even for young kids.

Lunar Eclipses and Solar Eclipses

The Short Answer:
What is an eclipse?

	An eclipse happens when a planet or a moon gets in the way of the Sun’s light. Here on Earth, we can experience two kinds of eclipses: solar eclipses and lunar eclipses.
	

Below, check out a visualization of the April 8, 2024, total solar eclipse!

What’s the difference between a lunar eclipse and a solar eclipse?

Solar Eclipse
A solar eclipse happens when the Moon gets in the way of the Sun’s light and casts its shadow on Earth. That means during the day, the Moon moves over the Sun and it gets dark. Isn’t it strange that it gets dark in the middle of the day?
This total eclipse happens about every year and a half somewhere on Earth. A partial eclipse, when the Moon doesn’t completely cover the Sun, happens at least twice a year somewhere on Earth.

Note: This diagram is not to scale. Credit: NASA/JPL-Caltech

A total solar eclipse was visible over the continental United States on Aug. 21, 2017. This image was captured in Hopkinsville, Kentucky during the 2017 eclipse. Credit: NASA/MSFC/Joseph Matus

But not everyone experiences every solar eclipse. Getting a chance to see a total solar eclipse is rare. The Moon’s shadow on Earth isn’t very big, so only a small portion of places on Earth will see it. You have to be on the sunny side of the planet when it happens. You also have to be in the path of the Moon’s shadow.
On average, the same spot on Earth only gets to see a solar eclipse for a few minutes about every 375 years!

Visit Solar System Ambassadors for information and examples of past events in your area.

Special Event with a Local Scientist
Scientists studying the Sun and its impact on Earth can bring the excitement of their latest research to your education programs. Past museum programs have hosted talks and question-answer sessions with scientists as part of their Sun-Earth Day celebrations. If you would like to invite a scientist to participate in your events, please contact Carolyn Ng.

Kiosk or Computer Station
With access to a computer or a simple kiosk/computer station, you can create an instant exhibit that allows users to explore Sun-Earth Connection in depth. Total Eclipse: Solar Eclipses and the Mysteries of the Corona, Space Weather Media Viewer, and Traditions of the Sun are all available for free online and on CD-ROMs by request.

Cultural Programs
Not only is the Sun an important focus of scientific research, it has also been an important cultural and spiritual symbol to people around the world both in the past and today. In fact, celestial events such as total eclipses have inspired people to observe and understand the Sun-Earth-Moon system. As with Sun-Earth Day 2005, Ancient Observatories - Timeless Knowledge, and Eclipse 2008 we encourage education programs where the public can explore the science of the Sun within its cultural context. Visit the Exploratorium website for examples of past programs.

Solstice and Equinox
Solstices are special days of the year with the most and least hours of daylight; equinoxes are days with equal hours of daylight and night. These are wonderful opportunities for people to become aware of the motion Earth relative to the Sun and understand how it affects the seasons. These days are also celebrated in many cultures and often used to guide planting and harvest. Refer to the new Sun-Earth Day Calendar for a complete listing of dates.

Children's Literature Program / Story Time
For a list of books that focus on eclipses and Sun-Earth Connection, visit the Children's Books page in our Multimedia section.
Lunar Eclipses and Solar Eclipses | NASA Space Place – NASA Science for Kids
It’s true that the Moon goes around Earth every month, but it doesn’t always get in Earth’s shadow. The Moon’s path around Earth is tilted compared to Earth’s orbit around the Sun. The Moon can be behind Earth but still get hit by light from the Sun.

In this diagram, you can see that the Moon’s orbit around Earth is at a tilt. This is why we don’t get a lunar eclipse every month. This diagram is not to scale: the Moon is much farther away from Earth than shown here. Credit: NASA/JPL-Caltech

Because they don’t happen every month, a lunar eclipse is a special event. Unlike solar eclipses, lots of people get to see each lunar eclipse. If you live on the nighttime half of Earth when the eclipse happens, you’ll be able to see it.

Remembering the Difference
It’s easy to get these two types of eclipses mixed up. An easy way to remember the difference is in the name. The name tells you what gets darker when the eclipse happens. In a solar eclipse, the Sun gets darker. In a lunar eclipse, the Moon gets darker.

Watch the Skies -
On December 4, 2023 periodic Comet 12P/Pons-Brooks shared this telescopic field of view with Vega, alpha star of the northern constellation Lyra. Fifth brightest star in planet Earth’s night, Vega is some 25 light-years distant while the much fainter comet was about 21 light-minutes away. In recent months, outbursts have caused dramatic increases in brightness for Pons-Brooks though. Nicknamed the Devil Comet for its hornlike appearance, fans of interstellar spaceflight have also suggested the distorted shape of this large comet’s central coma looks like the Millenium Falcon. A Halley-type comet, 12P/Pons-Brooks last visited the inner Solar System in 1954. Its next perihelion passage or closest approach to the Sun will be April 21, 2024. That’s just two weeks after the April 8 total solar eclipse path crosses North America. But, highly inclined to the Solar System’s ecliptic plane, the orbit of periodic Comet 12P/Pons-Brooks will never cross the orbit of planet Earth. Credit: Dan Bartlett
“Comet 12P/Pons-Brooks is an intrinsically bright Halley-type comet that underwent an outburst back in July. Pressure from sunlight (radiation pressure) has caused the gas and dust surround the comet to assume a horseshoe shape, which some observers say reminds them of a devil with horns. Spring will see two phenomena that would have terrified our ancestors – a solar eclipse turning day into night and a “devil” comet. Should be exciting!” he exclaims.
Cooke also shared his picks for the top three meteor showers in 2024:

Perseids in mid-August – The Perseid meteor shower is always a stunner and this year, there will be no moonlight to spoil the show.
Eta Aquariids in early May – This is an outburst year with visual rates as high as one per minute for observers in the Southern Hemisphere.
Geminids in mid-December – The number of bright meteors is expected to outshine the strong Moon interference.

 
The featured composite image was taken during the 2018 Perseids from the Poloniny Dark Sky Park in Slovakia. The dome of the observatory in the foreground is on the grounds of Kolonica Observatory.
