What would happen if all the planets would align?


Nothing. Almost nothing. No earth quakes, no tidal waves. The influence of other planets on Earth would be so small that that they would be impossible to see. The Moon has more influence over our tidal waves than even the Sun.

Actually, the Moon has 3x more stronger tidal force than the Sun and tens of thousands of time than Jupiter or Saturn. Due to the high distance to the planets an alignment cannot influence anything on Earth. The last question in the video is quite interesting: what if you replace the Moon with Jupiter. Then the tidal forces would be so high on Earth that we would have volcanic activity and tidal waves like it crazy and it is doubtful we would have a nice life in here.

Mystery solved.

The planet with two suns


Kepled 16b is a planet with two suns. Such a planet is called circumbinary and it located at 200 light-years from us. Kepler 16b is a big planet and orbits the tow suns, which in turn orbit each other at close proximity.

Kepler 16 is the system. In it Kepler 16A is the big star, then Kepler 16B is the small star and Kepler 16b is the planet. Upper case letters like B, for stars, and lowercase letters, like b, for planets.

Kepler 16b has a surface temperature of about -100 degrees Celsius and is about the size of Saturn, as it is a gas Giant. It has a gravity 1.5 times the one we have here.

Yup, the Universe has lots of surprises.

How does it rain on different worlds? What does it rain in there?

ASAP Science shared a greta infographic made by American Infographic and its amazing to see how it rains on other worlds, planets or satellites from our Solar System and beyond.

For example, it rains with different substances on different worlds:
– Earth – water
– Venus – sulfuric acid
– planet HD189733b – glass
– Neptune – diamons
– OGLE-TR-56b – iron
– satellite Titan – methane

Neil deGrasse Tyson about dying on other celestial bodies

If you try to live on the Sun, then you die instantly. On mercury, Venus or other planets you get to live a couple of seconds and then you die. The only place safe is still Earth. Why would you die on other planets? Let Neil deGrasse Tyson explain it to us.

How do planets sound like?

The planets have a sound of their own and it is really strange. NASA Space Sounds shows off the corresponding sounds generated by complex interactions of charged electromagnetic particles from the solar wind, ionosphere, and planetary magnetosphere. They sound much like you would play a video on slow motion and then try to hear the sound.

Maybe the planets talk to each other and their time frame is way longer than ours 😀 Just kidding. Have fun listening t the sounds of the planets.

Why Pluto is NOT a planet [astronomy]

C.G.P. Grey does amazing videos which teach us some of the less known facts around us. Like the fact that Pluto is not a planet and is merely an asteroid (dwarf planet, ok?) in the Kuiper Belt or that the definition of “planet” is a little bit skewed.

Pluto is not considered a planet anymore because it is very tiny and lots of other cosmic object almost the site of Pluto orbit in the same area called the Kuiper Belt. Honestly I grew knowing that we have nine planets, but I need to give place to scientific reason and send Pluto to the limits of the class. So, Pluto, we had a good run.
