Which star is brightest?
Sirius ASirius, 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..
Does the universe have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Can you see stars in space?
Of course we can see stars in space. We see stars more clearly from space than we do from Earth, which is why space telescopes are so useful. … Even in space the stars aren’t overly bright, and our eyes can lose dark adaption pretty quickly. NASA An image from the ISS of stars and glowing layers of Earth’s atmosphere.
What is the closest sun to our sun?

What is the hottest star color?

Which star is nearest to Earth?

Which is the biggest known star?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.
How far is a star from Earth?
4.364 light yearsAlpha Centauri A/Distance to Earth
What is the hottest planet?
VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
What’s the hottest star in space?
The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun. Like Baskin-Robbins, Wolf-Rayet stars come in a variety of flavors.
How far is the second closest star to Earth?
In 2016, astronomers discovered a planet orbiting Proxima Centauri, the nearest star to our sun, just 4 light-years away. Now, they believe they have found an exoplanet around Barnard’s star, which at 6 light-years away is the second-closest star system.
How far away can we see in space?
30 billion light-years awayToday, the most distant objects we can see are more than 30 billion light-years away, despite the fact that only 13.8 billion years have passed since the Big Bang. The farther a galaxy is, the faster it expands away from us and the more its light appears…
What planet is closest to the sun?
MercuryZipping around the sun in only 88 days, Mercury is the closest planet to the sun, and it’s also the smallest, only a little bit larger than Earth’s moon.

Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
Is Hubble still in space?
Eleven years after NASA’s fifth and final servicing mission in May 2009, Hubble is still going strong. The Space Telescope Science Institute still receives some 1,200 observing proposals each year, of which only about 250 can be accommodated.
