What Happens When Galaxies Collide?
Galactic collisions are among the most spectacular events in the cosmos. Collisions between galaxies are commonplace among galaxies that coexist in the same cluster.
How Many Earth-Like Planets Are There In The Milky Way?
The Earth is generally viewed as a unique planet, and in terms of all the planets in our solar system, it most definitely is.
The Largest Volcano In The Solar System
Volcanic eruptions are a common occurrence on Earth, yet the presence of volcanoes is not unique to the Earth.
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.
Neptune
Orbiting the sun at a distance of 2.8 billion miles (4.5 billion kilometers), Neptune is the fourth-largest planet by diameter and third-largest by mass.
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.
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.
Venus
Venus is the second planet from the sun and the nearest planet to the Earth. On average, Venus orbits the sun at a distance of 67.2 million miles.
Saturn
Suspended against the darkness of space, Saturn is truly a sight to behold. Saturn is the second largest planet in the solar system by size.
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?
