Explore the vastness of the universe, from the smallest moons to the billions of galaxies that make up the cosmos. This engaging journey highlights the immense scale, scientific curiosities, and fascinating facts about planets, stars,...

We explore the fundamental nature of entropy and its deep link to information. If you were taught that entropy measured disorder, you are in for a treat!

Whether it’s Marvel’s Thor, Disney’s Moana, or those Titans that clashed in that movie, pantheons of mythic heroes are everywhere in popular culture. But those Hollywood films barely even begin to scratch the surface of the wild stories...

As you go faster, what happens to time and space? What would happen if you could manage to go the speed of light? Astrum Answers!

Where is the centre of the universe? Where do astronomers look in space to see where the Big Bang originated?

The James Webb Space Telescope's journey from start to finish.

Supermassive black holes and their distribution in the universe.

The Hubble Space Telescope, active for over 30 years, has revolutionized our understanding of the universe by capturing stunning images of galaxies at various stages of evolution, from vibrant starbursts to dying elliptical remnants....

Olbers' Paradox. With so many stars in the universe, why is space black and not white with light? Astrum Answers!

What makes a planet a planet? And what makes a star a star? Once we know this these defining characteristics, we start to notice that these definitions can overlap. Which begs the question, can a planet be bigger than its parent star?

How can scientists possibly know the age of the universe? Well, through a variety of factors, including redshift, the CMBR and more.

Quasars, or extremely active black holes are the brightest objects in the universe. But aren't black holes meant to be invisible? Based on the Illustris Project simulation, we also look at radio-mode and quasar-mode feedback, seemingly...

Scientists can't use tape measures, rulers or lasers to measure the astronomical distances to stars and galaxies, so how do we do it?

Can planets exist in multi-star systems, and what would that look like from their perspective?

Pi (π) is a fascinating number with many applications in mathematics, physics, and engineering. Its infinite decimal representation is a reminder of its fundamental nature in the universe. Mathematician Johann Lambert proved that pi is...

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical...

Sun is obviously the hottest thing in our Solar System, but it is a mere candle when compared to several other stars and stellar phenomena, particularly supernova. A supernova is a transient event that marks the last evolutionary stage...

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time...

A particle accelerator is a machine that accelerates particles. More specifically, it accelerates elementary particles, like protons and electrons, at extremely high speeds—almost 99.99% of the speed of light. These particles are then...

Neutron stars are formed from the core of some starrs. Neutron stars generally have a radius of only around 12 km. With masses exceeding 1.4 times that of the Sun, these are some of the densest objects in the Universe. A tablespoonful of...

Multiverse theory suggests that our universe, which consists of billions and billions of planets, stars and galaxies and extends out tens of billions of light-years, may not be the only universe that exists. There could be another...

The tale of mathematics is as old as humanity. It has evolved from simple math, like counting cattle, to an intricate study of an object through abstract concepts that we know today. It was not until 600 BC, when civilizations settled,...

The Apollo 13 crew was the farthest distance that humans have traveled from Earth. On April 14, 1970, the crew was 400,171 kilometers (248,655 miles) from Earth. The Apollo 13 mission was the third manned mission intended to land on the...
