Earth is an average planet with a diameter of 12,700 km. But a thousand Earths could be stacked on another planet, Jupiter. A thousand Jupiters in the sun. Or the sun could cover one million Earths with a diameter of 1.39 million kilometers. Look at how small the earth is in comparison. If the sun…
Radio images reveal fast-moving electrons interacting with the galaxy’s magnetic field. They help us map atomic and molecular hydrogen and hot ionized regions. Infrared images show where starlight heats the interstellar gas and dust and reveal red giants, planetary nebulae, and young, massive stars deeply embedded in their parental molecular gas clouds. Visible light shows…
An explosion from a new and unnamed sunspot created the X-Class flame, the first of the 25 solar cycles. An X-ray explosion travels to Earth at the speed of light and collides with the upper part of our atmosphere, causing a shortwave radio blackout in the Atlantic Ocean and coastal areas. The blackout map above…
Pegasus is a constellation near Pisces. 51 Pegasi is a star that is barely visible to the naked eye. It is about 50 light-years from Earth. That is, when we see that star, we see light that traveled five decades ago. Michel Mayor and Didier Queloz, researchers at the University of Geneva in Switzerland, who…
Everything in the universe is based on certain laws. One such law regarding black holes was discovered in 1971 by the British physicist Stephen Hawking. One prediction according to this theory is that the area of the event horizon of black holes will never decrease. Furthermore, the event horizon area of another black hole formed…
The Solar System, in which the planet Earth. The only place in the universe where we can now say for sure that there is life.It is this thought that touches the depths of human curiosity that mainly motivates us to discover the planets outside the solar system.One of man’s primitive curiosities is whether life exists…
When we look through a Kepler telescope. The size is determined by looking at the amount of light that passes through the front of a planetary star.It calculates the year by looking at the time differences that pass through itThen the atmospheres can be understood by looking at the spectrum of a planet as it…
Venus is covered by clouds of opaque and light-reflecting sulfuric acid, and Venus has a darker atmosphere than all other rocks.
SizeMercury is the smallest planet in the Solar System in mass and diameter. It is slightly larger than Earth’s Moon. HeatMercury’s surface temperatures range from −173 degrees C at night to 427 degrees C during the day. This is because the planet does not have the atmosphere to trap heat, and the energy from the…
