What makes a star shine?
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot).
The source of their energy is nuclear reactions going on deep inside the stars.
In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star..
Why is Venus called the morning and evening star?
Venus was Phosphorus in the morning and Hesperus in the evening. We can thank Pythagoras around the 5th century B.C. for pointing out that Hesperus and Phosphorus were really one and the same. Because they orbit the sun more closely than Earth does, Mercury and Venus are called “inferior” planets.
Does Venus twinkle like star?
Venus reaches inferior conjunction today, officially leaving the evening sky. It has been low in the sky, where Earth’s atmosphere has caused Venus to scintillate, or twinkle, in many colors. Planets usually shine steadily. But bright Venus is twinkling now – shining in multiple colors – because it’s so low in the sky.
Is Venus a morning or evening star now?
Venus – the brightest planet – reached its greatest elongation from the sun in the morning sky on August 12 or 13 (depending upon your time zone). But dazzling Venus will remain bright and beautiful as a morning “star” for the rest of this year.

What is the first star to appear at night?
VenusVenus shines so brightly that it is the first “star” to appear in the sky after the Sun sets, or the last to disappear before the Sun rises. Its orbital position changes, thus causing it to appear at different times of the night throughout the year.
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.
Which star shines the brightest?
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star.

What 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.
