What are the characteristics of the planets that have been found so far around other stars?
What does this mean about their positions? They are probably closer to their star than the Earth is to the Sun. In general, what are the characteristics of the planets that have been found so far around other stars? They are the mass of Saturn or larger, and are therefore Jovian-type planets.
What did the Hubble telescope discover?
The telescope was named after American astronomer Edwin Hubble. Born in 1889, Hubble discovered that many objects previously thought to be clouds of dust and gas and classified as nebulae were actually galaxies beyond the Milky Way.
Which planet shows the greatest amount of cratering on its surface?
Mercury and the Moon Impact craters dominate the surfaces of Mercury and the Earth’s Moon. Both bodies lack liquid water on their surfaces that would erode impact craters over time. They also lack an atmosphere which, on planets like the Earth and Venus, could disintegrate meteoroids before they impact the surface.
What is the Hubble Space Telescope and what does it do?
Hubble is solar-powered. Hubble takes sharp pictures of objects in the sky such as planets, stars and galaxies. Hubble has made more than one million observations. These include detailed pictures of the birth and death of stars, galaxies billions of light years away, and comet pieces crashing into Jupiter’s atmosphere.
How does NASA take pictures of space?
Hubble uses a digital camera. It takes pictures like a cell phone. Then Hubble uses radio waves to send the pictures through the air back to Earth.
What is the real color of space?
Space emits a range of wavelengths of light, some we can see others we can’t. The majority of emissions are of red and blue light which are easily visible to the human eye but there are also UV, X-rays and gamma rays which are invisible.
Why can you not see stars in space?
The stars aren’t visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
What happens if you fart in space?
On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.
Is space completely silent?
The song fits the video well: Without any air to transmit sound, space is indeed completely silent. Russian cosmonaut Sergey Ryazanskiy, Italian astronaut Paolo Nespoli and American astronaut Randy Bresnik captured the stunning footage from August through October 2017 on the International Space Station.
Why is sound not heard in space?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
