Why is Pluto no longer considered a planet?

All the way in the late 19th century, astronomers have predicted that there must be an object that disturbs Uranus‘s orbit. Later in 1930, the American 27-year old Clyde W. Tombaugh discovered an object only 16% of Earth, which was named, after the God of the Underworld, Pluto. The discovery made headlines around the globe. There were […]

The Moon

Earth’s natural satellite, the Moon, is thought to have formed about 4,5 billion years ago as a result of a collision between the young Earth (which was smaller than the Earth today) and an object about the size of Mars. The impact spewed out a huge amount of rocky debris, which eventually coalesced to form the […]

Aurorae

An Aurorae is a colorful display of lights in the sky, caused by the collision of energetic particles from the Sun – the solar wind – with gas particles in Earth’s atmosphere. Aurorae are most often seen in the Arctic and Antarctic regions in winter. The Aurorae in the Northern Hemisphere is known as the Northern Lights or […]

The first image ever of a black hole

For the first time, humanity has seen an actual black hole. This achievement took supercomputers, 8 radio telescopes on five continents, hundreds of researchers, and vast amounts of data to accomplish. The results from this project, called the Event Horizon Telescope, were announced on 10 April 2019. The results helped to confirm (again) Einstein’s theory […]

NASA heading back to Moon

NASA is accelerating plans to return Americans to the moon. “It’s important that we get back to the moon as fast as possible. This time, when we go to the moon, we’re actually going to stay. We’re not going to leave flags and footprints and then come home to not go back for another 50 years. We’re […]

InSight successfully lands on Mars

Sent on 5 May 2018, the NASA InSight Mars lander successfully landed on Mars on November 26 2018, after a 458 million km (301 million miles) journey. This Mars lander is so special, because it will not only study the surface of the Red Planet, but also its interior, so we can understand more about […]

Arecibo Message

On 16-11-1974, 45 years ago,the SETI, Search for Extra-Terrestrial Intelligence, sent a message to Messier 13 Globular star cluster, 25000 light years away, hoping that they will get a response. The “Arecibo Message” was broadcast into space a single time via radio waves from the Arecibo radio telescope in Puerto Rico. The message consists of approximately 210 bytes of data. The message […]
