Asteroids, comets, meteors, and meteorites are all words that seem interchangeable, but they are not! Whilst they do have similarities, it’s a good idea to get to know the differences between them when trying to accurately detail or describe the night sky. So, what’s the difference? Below is a brief
Not too long ago, the idea of habitable planets beyond our solar system was reserved for science fiction, but now, it’s not such a far-fetched notion. With each passing year, scientists are discovering more and more potentially habitable planets. One of the most promising specimens at the minute is an
We’ve all heard them being used, either in real life or science-fiction, but is there a difference between a spaceship and a spacecraft? Spacecrafts are often confused with spaceships. Is there really a difference? A spacecraft is a vehicle designed to travel through space. Spaceships are also vehicles that travel
Wormholes are hypothetical shortcuts between two distant points in space-time. They would allow us to travel faster than light, and according to Einstein’s general theory of relativity, they might exist. Theoretically, wormholes could be created using exotic matter, such as dark energy, or even ordinary matter. Wormhole shortcuts are called
The Fermi paradox is a popularly cited argument against the existence of extraterrestrial civilizations in our galaxy or beyond. It states that, if advanced alien civilizations are common in the universe, then we should have seen evidence of their presence by now. After all, they’ve had enough time to find
There has been much speculation over the years about whether or not extraterrestrial life exists. The idea of alien life has captured our imagination since ancient times and continues to fascinate us today. There is no doubt that some of the most interesting questions in science revolve around the possibility
Astronomers have been using telescopes to look at the moon since the early 19th century. They’ve even sent probes to explore its surface. The Moon has always fascinated us. From ancient times, humans have wondered whether it was inhabited or not. In 1877, astronomer William Lassell discovered the first crater
A telescope is a device that magnifies distant objects. Telescopes come in various sizes from pocket size to large ones that can be mounted on a tripod. The larger the telescope, the better its magnification power. Telescopes can be used to view celestial bodies such as stars, planets, moons, comets,
If you’re new to astronomy or just want a refresher course on the basics of using telescopes for stargazing, this guide will help get you started with your first telescope. Keep reading to discover our ultimate beginner’s guide to magnification with telescopes. How Does A Telescope Work? The primary function
How much light pollution affects our view through telescopes? Is it possible to see stars without light pollution? Astronomy has always fascinated us. We love learning about the universe and observing the night sky. Too much light pollution from cities and towns can ruin your viewing experience. Have you wondered
Astronomy has always fascinated me. I love looking at the stars and planets in the sky. Unfortunately, it’s impossible to see them from my house because of the light pollution. Astronomers estimate that there are over 400 billion galaxies in our universe. The Milky Way alone contains 100 billion stars.
A telescope is a device that magnifies distant objects. The image produced by a telescope is called a telescopic image. Telescopes come in two types: refractors and reflectors. Refractors focus light using lenses, whereas reflectors use mirrors. The first known telescope was built in the 15th century by Chinese astronomers.
What Are Gravitational Waves? When an object moves, it creates waves in the fabric of space-time. The faster the object is moving, the more powerful these waves become. When the wave reaches us, we see them as ripples in spacetime, known as gravitational waves. Gravitational waves are ripples in space-time
Vacuum energy has been measured since the early 20th century, but its existence remains controversial. Why? Because vacuum energy isn’t directly observable. How does it work? What is it? And why should anyone care? What Is Vacuum Energy? The concept of vacuum energy was introduced by Albert Einstein in 1917.
Asteroid impacts occur rarely, but they can be devastating. The last significant impact was 65 million years ago, when a huge asteroid struck the Yucatan Peninsula off Mexico, causing mass extinctions and changing the course of life on Earth. There are currently over 100,000 known asteroids in our solar system.
Have you ever wondered why some stars are named after animals or plants while others are named after people? Picture saved with settings applied. The International Astronomical Union (IAU) has cataloged over 100,000 stars. They are organized into groups called constellations, each representing a mythological figure from Greek mythology. In
As a space enthusiast, you have probably heard the terms quasar, pulsar, and neutron star before. 1920×1080 Wallpaper But, what is the difference between these three amazing space phenomena? What makes each of them unique? This article will discuss the three terms in detail, provide some interesting facts about them
Wormholes are hypothetical shortcuts through space-time that connect distant regions of the universe. They were first theorized by physicist John Wheeler in 1935 and have become one of the most intriguing concepts in modern physics. Although there is no direct evidence for them, scientists believe that some form of exotic
Neutrinos are subatomic particles that pass through matter without interacting with it. They are extremely weakly interactive and therefore pose no threat to humans. Neutrinos come from nuclear reactions within stars and other celestial bodies. The neutrino radiation emitted by these sources is very low energy and does not pose
The asteroid that struck Earth 65 million years ago was large enough to cause global devastation. It slammed into the Yucatán Peninsula of Mexico, creating a massive crater that is now known as the Chicxulub Crater. Scientists believe the impact triggered a mass extinction event that wiped out the majority
Satellites are often confused with spacecraft, but they are two very different things. What exactly is the difference between them? Satellites are man-made objects that orbit Earth at altitudes ranging from hundreds to thousands of miles. They are usually used for scientific research or military purposes. A spacecraft on the
The United States government spends billions of dollars each year on NASA research and development. In fact, NASA has spent nearly over $100 million per day since its inception. However, SpaceX is a private company that was founded by Elon Musk. They offer low-cost launch services to customers who want
Planets are celestial bodies that circle the sun. They are usually large enough to be visible from Earth. Exoplanets are planets outside our solar system. They orbit their host star at distances much greater than Mercury orbits the Sun. Exoplanets are discovered using telescopes. These include NASA’s Kepler space telescope,
What would happen if humans left Earth? Would we become extinct or thrive elsewhere? What would life be like on other planets? These questions are at the heart of space exploration. Space exploration has always fascinated humans. From the earliest days of human history, we’ve dreamed of exploring new worlds
