Space
How Big Is The Universe?
The universe is unimaginably gigantic. The human brain is simply incapable of truly grasping the immensity of space.
Planet X (Planet Nine)
Planet X, also called Planet Nine, is a hypothetical planet that orbits the sun in the far outer regions of the solar system.
Is Time Travel Possible?
The concept of time is one of the most mysterious concepts in physics. Traveling into the future is possible, but scientists do not know if backward time travel is possible.
Earth
Earth is the fifth-largest planet in the solar system and the largest of the inner rocky worlds. The Earth is 7,926 miles (12,756 kilometers) in diameter.
Asteroids
Most asteroids are minor and far, so observing them without equipment is impossible. Only one asteroid, called 4 Vesta, is sometimes visible to the naked eye.
How Do We Find Planets Around Other Stars?
Ever since humanity came to the realization that the Earth is one of many planets, we have dreamed about the possibility of worlds around other stars.
Is There Life On Jupiter’s Moon Europa?
The solar system boasts a number of worlds that possess the necessary conditions for the existence of life, the most promising of which is Jupiter’s moon, Europa.
What Are Dark Matter And Dark Energy?
As previously mentioned, 27% of the stuff in the universe is composed of dark matter. The only aspect about dark matter that scientists truly know is that it exerts a gravitational force.
The Lifecycle Of A Star
Nothing in this universe lasts forever. Even the stars themselves cease to exist. When we look at the night sky, the stars seem eternal.
Solar System
What is a solar system? A solar system is essentially a star orbited by one or more planets bound to it by its gravitational pull.
Kuiper Belt
The Kuiper Belt likely formed soon after the planets came into existence. Eight planets emerged out of the protoplanetary disk around the sun.
The Sun
The sun is the nearest star to the Earth, and it is the powerhouse of the solar system. More than 99% of all the mass in the solar system is contained within the sun.
Kepler-452b
Kepler 452b was discovered using the transit method. While observing the star Kepler 452, Kepler looked for a change in the star’s brightness caused by a planet passing in front of the star.
Kepler-22b
If certain conditions are met, such as an Earth-like atmosphere, liquid water could theoretically exist on the surface of Kepler 22b.
Proxima Centauri b
Proxima Centauri is a red dwarf star that is far smaller and dimmer than our sun. The star is so dim that it is not visible to the naked eye.
Countries With The Most Space Travelers
The idea of sending humans into space was once considered nothing more than a fantasy. It was not until the mid-20th century that the prospect of sending humans into space became plausible.
Which Planet In Our Solar System Has The Most Gravity?
Each of the eight planets in our solar system has its own gravitational pull, whose strength is related to its mass. The smaller a planet's mass, the weaker its gravity.
Biggest Moons In Our Solar System
Some moons are so large that if they were orbiting the Sun instead of a planet, they would likely be considered planets in their own right.
How Old Is The Solar System?
For most of human history, there have been varying assumptions about the age of the Earth and the rest of the planets. How old is the solar system, and how was it determined?
How Many Shuttles Were Lost In Space?
Space travel is never easy. It is a dangerous endeavor, one in which people put their lives at risk in the name of exploration.
Why Methane Can Be A Sign Of Life Outside Of Earth
Although methane isn’t overly common in the Earth’s atmosphere, it plays a vital role in our planet’s atmosphere.
What Are Black Holes?
Any discussion on black holes must first begin with a simple question: what are black holes?
