The hottest part of the Sun is its core at 27 million F° (15 million C°).
The Sun’s activity, from its powerful eruptions to the steady stream of charged particles it sends out, influences the nature of space throughout the solar system.

The Large Magellanic Cloud (LMC) is a satellite of the Milky Way, containing about 30 billion stars. Seen here in a far-infrared and radio view, the LMC’s cool and warm dust are shown in green and blue, respectively, with hydrogen gas in red.

A ray of zodiacal light, sunlight reflected by dust grains orbiting between the planets in the Solar System, rises from the horizon. Arching across the top is the central band of our Milky Way Galaxy. Jupiter and Saturn are also visible in the background night sky.

On the left, the central plane of our home galaxy extends from the horizon past the middle of the sky. On the right, an auroral oval also extends from the sky's center -- but is dominated by bright green-glowing oxygen.

The main asteroid belt lies between Mars and Jupiter, and Trojan asteroids both lead and follow Jupiter. Scientists now know that asteroids were the original "building blocks" of the inner planets.

The Milky Way is the galaxy we are living in. It is a barred spiral galaxy with an estimated diameter of 87,400 light-years but only about 1,000 light years thick at the spiral arms
It is estimated to contain 100–400 billion stars
We’ve never seen it from outside !

This illustration reveals how the gravity of a black hole warps space and bends the light of a distant star behind it. The black hole traps light due to its intense gravitational field, hence it cannot be seen directly.

The solar cycle is a nearly 11-year change in the Sun's activity measured by counting sunspots on its surface
The measurements started in 1750 and we are now in cycle 25.
This cycle was predicted to be less intense than it is actually.
Auroras intensity depends on this activity.
