What Is Antimatter?
Antimatter is a form of matter that has an opposite electric charge to regular matter. When the two forms of matter meet, they cancel each other out.
How Big Is The Milky Way?
The Milky Way Galaxy is estimated to be 100,000 to 200,000 light years across. The size of the Milky Way is determined using both parallax and variable stars.
The Ten Biggest Stars In The Milky Way
The Milky Way contains over 100 billion stars, including our sun. The sun seems big, yet it is dwarfed by some of the other stars in our galaxy.
What Are Supermassive Black Holes?
These black holes are called supermassive black holes, and they can be anywhere from a million times the mass of the sun to over 100 billion times the mass of the sun.
Is There A Center Of The Universe?
Humanity once believed that the Earth was at the center of the universe. This was proven untrue, yet does the universe actually have a center?
How Much Would You Weigh On Each Planet?
Earth has the highest surface gravity of the inner rocky worlds, and so your weight on Earth will be higher than on Mercury, Venus, or Mars.
What Is A Meteor Shower?
Meteor showers are consistent astronomical events that occur every year. They are left over debris from comets that happened to cross the Earth’s orbit.
How Many Stars Are There?
The universe contains a vast amount of stars, and estimating their number requires knowing the number of galaxies in the universe.
Saturn’s Moon Iapetus
Saturn has one of the largest, most diverse moon systems in the solar system. One of those moons is Iapetus, and it is one of Saturn’s most unique moons.
The Different Types Of Planets
Planets are defined as either being rocky or gaseous, yet these categories also have subcategories. There are at least six different types of planet.
Gamma Ray Bursts
Gamma ray bursts are among the brightest, most energetic events in the cosmos. They form during the death of a massive star and the formation of a black hole.
The Star Eta Carinae
Other than Earth-sized flares and solar storms, the sun is stable enough for life to evolve and flourish on our world.
The Interstellar Medium
Rather than being completely empty, space is filled with gas and dust called the interstellar medium. Most of the interstellar medium is hydrogen and helium.
10 Facts About Mars
Mars is the most intensely studied planet in the solar system, and more is known about Mars than most other planets. Here are ten facts about the Red Planet.
The Quilted Multiverse Theory
If the universe is infinite in size, arrangements of matter and energy will eventually repeat, resulting in multiple parallel bubble universes within space.
What Are Exomoons?
Exomoons are moons that orbit exoplanets, planets that orbit stars other than the sun. To date, no exomoons have been confirmed, yet that will likely change.
What Shape Is The Universe?
The shape of the universe is either spherical, hyperbolic, or flat, which is dependent upon how the universe itself is curved.
Red Dwarf Stars
Red dwarf stars are the most common type of the star in the universe. Red dwarfs are also the smallest, dimmest, and oldest stars in the cosmos.
Space Travel Funding By Country
Funding for space travel was at its highest during the Space Race in the 1960s. Since then, funding has decreased, yet more countries are now going to space.
Can Alien Life Be Silicon Based?
All life on Earth is carbon-based. Does alien life also have to be carbon-based? Silicon is another element that could potentially be the basis for alien life
How Often Do Stars Die?
Stellar death is part of stellar lifecycles. Within the Milky Way, astronomers estimate that one star dies every year, while supernovae happen every century.
How Many Galaxies Are There?
To estimate the number of galaxies in the universe, astronomers take wide images of different regions of space. There is an estimated 200 billion galaxies.
Is The Moon Moving Further Away?
The moon has been gradually moving further away from the Earth ever since it formed 4.5 billion years ago. It is currently moving 1.48 inches away every year.
How Solar Flares Are Produced
Solar flares are energetic bursts of plasma that move outwards from the sun. They form from the interaction of the sun’s magnetic field and rotation.
James Webb Telescope Finds Water In Exoplanet Atmosphere
The James Webb Space Telescope has recently released data on the composition of an exoplanet’s atmosphere, finding evidence of water vapor.
First Images From James Webb Telescope
On July 11, 2022, NASA released the first color images from the James Webb Space Telescope, showcasing what is the most powerful telescope ever built.
How Many Dwarf Planets Are There?
The first dwarf planet was discovered in 1801, and since then, scientists have found potentially hundreds more. There could be as many as 120.
Five Reasons Why Humans Should Go To Venus
Venus is a potential target for human exploration. Some factors may make it more promising than Mars. Here are five reasons why we should visit Venus.
Could We Terraform Mars?
Humanity has long dreamed of travelling to Mars, and it may one day be possible to later its environment to support the existence of human life.
How Long Would It Take To Travel To Mars?
In order for humans to eventually travel to Mars, they will need to survive in space for extended periods of time, yet just how long would it take to travel to Mars?
How Planets Produce Magnetic Fields
Magnetic fields are common among the planets in our solar system. Although not every planet has a magnetic field, most of them do.
What Is Spectroscopy?
The science of spectroscopy is one of the most important areas of astronomy. Spectroscopy is the study of an object’s composition by examining the light it emits.
How Much Of A Threat Are Asteroids?
Space agencies from around the world actively track what are called near-Earth asteroids. These are asteroids that are located within Earth’s vicinity.
The Voyager Golden Record
Voyager 1 and 2 launched in 1977, and their journey brought them both to Jupiter and Saturn. Voyager 1 did not continue onto any other planets.
What Is A Light Year?
A light year is a simple form of measurement. One light year is equivalent to 5.88 trillion miles (9.46 trillion kilometres).
What Are Rogue Planets?
There are many planets that do not orbit a star, and instead, drift through the emptiness of interstellar space. These planets are called rogue planets.
What Is A Dyson Sphere?
Throughout human history, how we consume and use energy has changed drastically. Although it may sound like science fiction, in the future, we may have the energy of an entire star.
What Is String Theory?
Interestingly, there are some potential theories out there that combine the two pillars of physics, the most famous of which is string theory.
