Almost everything you could want to know about the closest planet to the Sun, Mercury. Real HD photos and videos taken by the MESSENGER probe. We discuss the orbit, climate, geographical features, and general physical characteristics or...

In 2017, Cassini ended its mission by disintegrating in Saturn's atmosphere. What were the final images it ever took?

Hubble doesn't just look at distant nebula and galaxies, but has also observed celestial bodies and events in our own solar system. So what has it seen? Images from Hubble / NASA / ESA.

Saturn's moon, Titan, is the only other body in the solar system that can support liquid on its surface. But not liquid water, liquid methane. What did NASA's Cassini discover about the methane lakes of Saturn's moon, Titan?

Mercury will be transiting the Sun on the 11th November 2019. What time will it be? How can I see it for myself? And why doesn't a transit happen much more regularly?

How do scientists plan to get astronauts to Mars when space radiation is so strong? What can be done about it? Astrum Answers!

While tiny, Earth now has a second moon, or natural satellite, named 2020 CD3. So, will we have to rewrite the text books?

NASA's Dawn spacecraft was the first spacecraft to orbit two extraterrestial bodies, Vesta and Ceres. But what did it do and discover while it was there?

The Sungrazer comets that were discovered minutes before they vapourised.

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...

Asteroids are small, rocky objects that orbit the sun, just like the rest of the planets and celestial bodies in our solar system. Although asteroids are present throughout the solar system, most of them live in the asteroid belt—a...

Since Earth completes one revolution around the sun in 1 year, it would make sense to think that after the completion of year, Earth would be exactly at the same spot where it was at the beginning of the year, wouldn't it? But is it...

The concept of the cosmic calendar was popularized by famous astronomer Carl Sagan to help people understand just how far apart on a time scale events in the Universe are. Basically, he arranged the 13.8 billion years of the Universe’s...

The rotation of the planet around its axis can be generally of two types: prograde and retrograde. Prograde rotation indicates that the motion is in the same direction as the Suns rotationwhich is counter-clockwiseif youre looking down...

Mercury and Venus have no moons because of their close proximity to the Sun. Any moon orbiting around them is likely be swallowed by the mammoth gravitational pull of the mighty Sun. All planets except for Mercury and Venus have moons....

While Neptune, the most distant planet in our Solar System, is 4.5 billion kilometers away from the Sun, Uranus, the second-farthest planet, is just 2.88 billion kilometers away. Uranus is more than a billion kilometers away from...

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...

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...

An increase in Earths rotational speed could have various impacts on life: ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might...

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...

Remember those old space movies where spaceships had to maneuver through a bunch of asteroids scattered around and blocking the path of the ship? Well, that's not really true. The asteroid belt contains asteroids which are so far apart...

Or geomagnetic storm, a severe disruption of the Earth's magnetosphere that can cripple satellites, and even cause severe damage to electrical systems on the ground. A Twig Science Glossary Film. Key scientific terms defined in just 60...

Orbital poles are the two regions of a planet at the extremes of its rotational axis. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning images and concise textual definitions. Twig Science...

An orbit in space which follows an oval-shaped path. Any small object orbiting a larger one in space will follow an elliptical orbit. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning images and...
