Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth. Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon).

Why do stars twinkle?

In fact, most of the stars are shining with a steady light. The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. … To our eyes, this makes the star seem to twinkle.

What is the most important star?

the SunThe most famous star in our sky is the Sun, the source of the heat and light that powers the solar system. It’s a G-type star that formed some 4.6 billion years ago. The Sun is a yellow-white dwarf that will continue its hydrogen-burning phase (that is, “live” on the Main Sequence) for another 5 or so billion years.

What is the actual shape of a star?

Most stars are much like the Sun—giant balls of gas burning billions of miles away. These spherical stars pump out a steady stream of light that crosses vast stretches of space before it illuminates the night sky.

What color is the hottest star?

Blue starsWhite stars are hotter than red and yellow. Blue stars are the hottest stars of all.

Why is a star shape with 5 points?

How hot is the hottest star in the universe?

Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.

Do stars die?

Stars die because they exhaust their nuclear fuel. … Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.
