Astrum investigates some examples of the longest and shortest years that we know of. The differences are mind-boggling!

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 big do you think our solar system is? Up until Pluto? A bit beyond? How big can other solar systems get? Astrum answers!

Gravitational microlensing events are revealing the mysteries of rogue planets, but what are they, and how does it work? And what role does the Nancy Grace Roman Space Telescope play in helping us spot more rogue planets in the future?

There is an exoplanet, discovered by ESO's VLT, where it rains iron. But WASP-67b is 690 light years away, how could we possibly know that?

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?

How much of an effect would a second Sun have on Earth? Is there a way it could work?

While the sun seems yellow to you from childhood, in reality, it is white. The reason why the sun appears yellow is because of the Earth’s atmosphere. When sunlight hits atmospheric particles, it causes electrons and protons to vibrate...

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...

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...

Hawking radiation was first discovered by English scientist Stephen Hawking in 1974. Prior to this discovery, our knowledge of black holes was very limited. It was believed that black holes were completely black and that they did not...

Space is full of radio waves, plasma waves, magnetic waves, gravitational waves, and shock waves, all of which can travel in space without a medium. These waves are recorded by instruments that can sense these waves, and the data is...

A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's...

Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

If you are still living under the assumption that the moon can only be seen in the night sky, you’re incorrect! The fact is that the moon is always hanging around our planet; sometimes, it’s visible during the day (given you have the...

Planetary orbits are elliptical because gravitational interaction over time changes the delicate balance of mass, velocity and distance from the star which otherwise keeps planetary orbit circular. For a very long time, from Ptolemy to...

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain...

From ancient civilizations to modern breakthroughs, learn about the nine most important cosmic discoveries that changed the way we look at our Sun, Moon and beyond. Learn how Copernicus challenged the status quo, Kepler unveiled the...

Orbital poles are the two regions of a planet at the extremes of its rotational axis.
