☄️ On 12 October it will be possible to see a bright comet with the naked eye.

Comet C/2023 A3 will reach its maximum brightness and will be available for observation from the Northern Hemisphere of planet Earth from 12 October.

At that time, the comet will be observable between the bright stars Spica (α Virginis) and Arcturus (α Volopassus).

The Mars rover Perseverance has travelled about 28 kilometres during its mission since landing in 2021 🟠

The Einstein Probe space observatory, a joint project between China and Europe to be launched in January 2024, has taken a new X-ray image of the Moon ⚪️

A video of Mercury made up of 56 photos taken by the cameras of the BepiColombo spacecraft, a joint project between Europe and Japan 🛰

Stars, like all objects in the galaxy, are constantly moving 🌌

However, the human age is too short to notice these changes in the sky.

The video shows the proper motion of stars in a small patch of sky around the constellation of the Big Dipper over a period of 300,000 years (150,000 BCE to 150,000 CE)

On 8 June 2004, Venus passed in front of the Sun 🟠 🟠

This phenomenon made it possible to observe the atmosphere of Venus

The collision of galaxies is not always a catastrophe 💫

Stars in galaxies are vast distances apart and do not collide when they merge. The interaction is between gas and dust clouds that merge to form shock waves.

These waves compress the gas, leading to intense star formation.

This is what the Sun looks like in outer space.

Why are stars different colours?

The colour of a star depends on its temperature. The hottest stars are blue and the coldest stars are red. Other factors, such as chemical composition, also affect the colour of stars.

The alpha-magnetic spectrometer installed on the ISS has detected an unexpectedly large number of antigelium particles

This observation, according to scientists, can not be explained by standard astrophysical models. Perhaps it indicates the existence of unknown processes in the cosmos. This study, which originally aimed to solve an old astrophysical mystery, may lead to the discovery of a new, unexplored phenomenon.

The Sun is much bigger than the Earth 🟠

It would fit 1.3 million planets like ours.

💫 The Draconids meteor shower will take place in the evening and night from 8 to 9 October.

Astronomers have promised up to 15 large and bright meteors per hour

Observations of the Rosetta spacecraft in 2016 recorded a "snowstorm" on comet 67P Churyumov-Gerasimenko ❄️

"Snowflakes" are particles of dust and ice lifted from the surface of a comet. Warming up as it approached the Sun, the comet began to release matter into the surrounding space.

A computer simulation has demonstrated the detailed process of the destruction of a star by a black hole 🌌

The model shows how a star with a mass and radius comparable to the Sun is destroyed by the tidal forces of a supermassive black hole (a million times more massive than the Sun)

From 2024 to 2038, the view of Saturn from Earth will gradually change 🪐

Changes in the mutual position of the planets in their orbits and the angle of rotation of the gas giant's rings will affect its appearance to Earth observers

The Earth's magnetic field is a giant invisible shield surrounding the Earth, protecting the planet from solar radiation.

The invisible forces extend from the Earth's poles thousands of kilometres into space.
