Astronomy is the natural science that studies celestial objects and phenomena, using mathematics, physics, and chemistry in order to explain their origin and evolution. Discover planets, moons, stars, nebulae, galaxies, and comets, incredible events like supernova explosions, gamma-ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation.

In this lesson, we will explore various topics related to space and celestial objects. We will learn about observatories, which are locations used for observing terrestrial or celestial events, and the different disciplines for which they have been constructed. We will also examine the field of astronomy and the role of astronomers in studying objects in space

Astronomy and cosmology are fields of science that study the universe and its origins, composition, and evolution. Over the centuries, many scientists and philosophers have contributed to our understanding of the universe and the laws that govern it. In this lesson, we will discuss some of the big names in astronomy and cosmology who have made significant contributions to these fields.

In this lesson, we'll discuss a valuable resource that educators can use to make STEM education more accessible and engaging for their students - the NASA Educators' Corner.

Welcome to our course on Astronomy! We will explore the wonders of the Universe, from planets to black holes, galaxies to subatomic particles, and even the eventual fate of the Universe itself.

In this lesson, we will be discussing naked-eye observations in astronomy. Astronomical observations can be done without any equipment like binoculars or telescopes. Naked eye observations are a great way to understand the Universe by looking at it.

Light pollution is a growing problem that has significant consequences for human health and the environment. However, by taking simple steps to reduce our use of artificial light and raise awareness about the issue, we can work together to preserve the beauty of the night sky and protect our health

The sky is a vast and beautiful expanse that has fascinated humans for centuries. In this lesson, we learn about the cycles that occur in the sky, from the daily rotation of the Earth to its yearly orbit around the Sun. As a result of these movements, stars, and planets appear to move in the sky, and different constellations become visible throughout the year. In this lesson, we will explore these cycles in more detail, discuss their significance, and offer advice for those who want to observe them.

The lunar phase or Moon phase is the shape of the directly sunlit portion of the Moon as viewed from Earth. The lunar phases gradually change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. 

A total solar eclipse happens somewhere on Earth once every year or two. What is an eclipse? Learn more about how solar eclipses happen, the four types of eclipses, and how to view the sun safely if you're within the path of totality.

In this lesson, you will learn how to make a pinhole projector, a simple and safe tool to observe a solar eclipse without having to look directly at the sun.

What is the definition of a solstice, and when do they happen? Is the winter solstice always the first day of winter? Find out what causes these bi-annual astronomical events, as well as how they bring about the shortest and longest days of the year.

The Hubble Space Telescope is a groundbreaking instrument that has revolutionized our understanding of the universe. It was launched in 1990 and has been in operation ever since, providing astronomers with unprecedented views of the cosmos. One of the main advantages of the Hubble Space Telescope is that it orbits outside of the Earth's atmosphere, which can distort and block light from distant objects.

A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. They are used for both terrestrial applications and astronomy. 

Gravity or gravitation is a natural phenomenon by which all things with mass or energy (including planets, stars, galaxies, and even light) are brought toward (or gravitate toward) one another

Tides are the rise and fall of the sea level that occurs on the Earth's coastlines. Tidal phenomena are the various effects that tides have on the Earth's oceans and coasts, such as the movement of water, the formation of currents, and the mixing of different water masses. Tides are caused by the gravitational pull of the Moon and the Sun on the Earth, and they have a number of important effects on the oceans and coasts.

Light is a fundamental concept that is essential to our understanding of the universe. Its properties, such as wavelength, intensity, and polarization, allow us to study the universe in ways that would otherwise be impossible. Through spectroscopy and other techniques, we can determine the composition and properties of objects in the universe, and learn more about the nature of our universe.

The universe is an incredibly vast and expansive place, with distances between objects that are difficult for most people to comprehend. In this lesson, we will discuss some of the ways that astronomers measure and express these vast distances, and how they are used to understand the universe and its structures.

Space is a fascinating topic that has inspired people to learn about the universe and even themselves. One of the best ways to learn about space is to start with the closest star to us, which is the Sun, also known as "Sol". The Sun is a big ball of superhot gas that provides energy to our eight-planet solar system. Without the Sun's energy, Earth would be a dark, frozen world with no life.

Let's explore the concept of the cosmic horizon and the observable universe, providing a comprehensive understanding of the fascinating subject of the cosmos.

Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history

How old is the universe, and how did it begin? Throughout history, countless myths and scientific theories have tried to explain the universe's origins

The Big Bang is a challenging concept to understand, but it is essential to understanding the universe we live in. It created everything and its effects are still felt today. To understand it better, it is helpful to learn about related arguments such as dark matter, dark energy, inflation, and multiverse.

The stars and how they can be categorized using their spectra. Together with their distance, this provides a wealth of information about them including their luminosity, size, and temperature.

In this lesson, we will explore the existence of brown dwarfs, which are celestial objects that are bigger than planets but not quite big enough to become stars. Brown dwarfs are formed in the same way that stars are formed but they do not have enough mass to start nuclear fusion in their cores. Instead, they just sit there and cool down until they become cold and dead. Brown dwarfs emit light in the infrared and almost nothing in the visible spectrum. They can be distinguished from stars by testing for the presence of lithium in them.

Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives

Which planets in our galaxy are "just right" for supporting human life?

Exoplanets are planets that orbit stars other than our Sun. The first exoplanet was discovered in 1992, and since then, scientists have found thousands of exoplanets using a variety of techniques, such as the transit method, the radial velocity method, and the gravitational microlensing method.

White dwarfs are incredibly hot and dense objects roughly the size of Earth.

Massive stars fuse heavier elements in their cores than lower mass stars.

Neutrons' stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars, flashing in brightness as they spin. Neutrons stars with the strongest magnetic fields are called magnetars and are capable of colossal bursts of energy that can be detected over vast distances.

Black holes are mysterious and fascinating objects in the universe. They are formed when a massive star collapses in on itself, creating a region of extremely high density and gravitational force. Black holes are so massive and dense that nothing, not even light, can escape their gravitational pull. This makes them invisible to telescopes, which is why they are called "black" holes.

Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars

A star cluster is made of thousands or even millions of stars

Astronomers study a lot of gorgeous things, but nebulae might be the most breathtakingly beautiful of them all

Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular. Galaxies can collide, and grow in size by eating each other.

The Milky Way. It’s a disk galaxy, a collection of dust, gas, and hundreds of billions of stars, with the Sun located about halfway out from the center

Gamma-ray bursts are not only incredible to study, but their discovery has an epic story all its own.

Pulsar planets are planets that are found orbiting pulsars or rapidly rotating neutron stars (the extremely dense core of a massive star that exploded as a supernova)

The Hubble Space Telescope can take only black-and-white images. But by analyzing the wavelengths of light that different elements emit in space, this man turns dull pictures of our universe into the colorful masterpieces we've come to love.
