Exoplanets!

 


Hello blog readers! Today we are going to learn about exoplanets.

What is an Exoplanet?

  An exoplanet is a planet that is orbiting other stars in our universe.

Key Points

  • Hubble and Kepler are two space telescopes that have found exoplanets.
  • Methods of finding exoplanets : Radial Velocity, Transit Method and Astronomy
  • The astronomy method is basically using powerful telescopes like Hubble to find exoplanets
  • The Transit Method used by Kepler was all about seeing little differences in a stars light. Basically when a little bit of a star's light wasn't reaching the Kepler Space Telescope, say for ex: the telescope would confirm an exoplanet.
  • The radial velocity method was basically using radar to determine the exoplanet's velocity and distance from the radar's starting point.
  • We have found exoplanets that are habitable.
  • Although we have found habitable exoplanets, we haven't found any alien life on exoplanets.
So this is a good start for starters about exoplanets. The Kepler Space Telescope is no longer active today, but you can visit  Hubble's website. Bye! I hope you had fun reading today's blog!

How to decarbonize the electricity sector by 2050

Wind, solar, and energy storage will not be dominant     First, before everyone thinks that wind, solar, and batteries are the future of electricity, everyone reading should know a key statistic against a future where wind and solar are dominant: we've started investing heavily in those three since 2000. We're almost halfway to 2050; yet the wind and solar percentage in the global electricity mix doesn't even make up a fourth of it. If we keep on going like this, we're only going to achieve a dominant wind and solar future at the end of this century.  If you aren't convinced, a wind and solar dominant world would require a lot of land to provide for the world's electricity needs, and as they increase, the amount of land covered by wind and solar would only increase. The materials needed to make wind turbines and solar panels would have to be acquired by rare earth mining, which would have to take place in countries like China since the environmental regulations ...

How quantum computers will change EVERYTHING

Intro In today's world, digital computers are everywhere, from our pockets to the cold void of space. However, a new generation of computers that are faster and better are starting to emerge. These are quantum computers, and when they come out, they will change the world in ways that are unimaginable today. But the question is, how? How will this new generation of computers change the world? That is the question that we will answer in this blog post. Google's quantum computer, named Sycamore Quantum vs Digital Computers In order to understand how quantum computers will change the world, we need to understand the differences between quantum computers and their digital counterparts. A digital computer operates on bits. These bits have two options: 0 and 1. These bits have tiny switches called transistors that control the flow of electricity within the bit. Electricity that's flowing represents a 1, while no electricity flowing represents a 0. These bits are the foundation for...

Helping hummingbirds!

Hi there! My full name is Shreyas Akula. I'm 8 years old. Please go to the end of the blog, ( not the comments) to click on the essential links. Did you know that plants don't produce their fruit all by themselves? Animals help plants produce fruit ! These animals are called pollinators . But in this era of human history, our activity is putting these animals into trouble ! Wait a second. You might not know what are pollinators are. So let's find out ! Pollinators transport pollen from flower to flower. Pollen carries the male reproductive  cells of the plant. How do pollinators transport pollen? Well, that's no problem for pollinators 'cause they are small! Okay, we are zooming into a flower! The pollinator, a bee has arrived! First, the bee goes to the middle of the flower. This part is called the stigma and located in the middle of a flower and is female. While making it's journey to the stigma, it bumps into the pollen dusters. If you you combine the anther ...
