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 The Kepler Space Telescope is no longer active today, but you can visit  Hubble's website.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!

Microsoft's Majorana 1: A Leap Toward Practical Quantum Computing

  In February 2025, Microsoft unveiled a groundbreaking advancement in quantum computing: the Majorana 1 chip. This development marks a significant step toward realizing practical, large-scale quantum computers. What Is the Majorana 1 Chip? The Majorana 1 chip is Microsoft's first quantum processing unit (QPU) designed to harness topological qubits. Unlike traditional qubits, which are susceptible to errors due to environmental noise, topological qubits are inherently more stable. This stability arises from the use of Majorana zero modes—quasiparticles that are their own antiparticles and are theorized to exist in certain quantum states. To create these topological qubits, Microsoft introduced a new class of materials known as topoconductors . These materials combine indium arsenide (a semiconductor) with aluminum (a superconductor) to achieve a state called topological superconductivity. When cooled to near absolute zero and exposed to specific magnetic fields, these materials...

The Origins of Life: A Journey to the Beginning

  Where did life come from? It’s one of the most profound questions humanity has ever asked. 🌍 The Early Earth: A Hostile Cradle About 4.5 billion years ago, Earth formed from cosmic dust. The young planet was a hostile environment—volcanic activity raged, the surface was molten in places, and the atmosphere was thick with carbon dioxide, methane, ammonia, and water vapor. This was not a place we’d associate with life. Yet, these chaotic conditions may have been the perfect incubator. ⚡ The Spark of Life: Chemical Origins In 1953, the famous Miller-Urey experiment demonstrated that amino acids—the building blocks of proteins—could form when electricity (like lightning) passed through a mixture of early Earth-like gases. This suggested that life’s raw materials could arise naturally. Some scientists propose life began in hydrothermal vents on the ocean floor. These deep-sea vents offer heat and minerals, creating chemical gradients—ideal for the emergence of complex molecu...

Einstein's 5 theories

  A bit of background on Einstein Albert Einstein was a German physicist and Jew born on March 14, 1879 whose discoveries helped to open up a new world of physics. When Einstein was a kid, he had a speech disorder, but he was very good at math and had a very curious mind. When Einstein was 5 or 6, he got sick, so a father bought him a compass, which made him wonder how the needle of his compass always points in the same direction. This really got Einstein interested in science. When Einstein was an adult, he was working in the Swiss Patent Office at Bern. A few years after working at the patent office, it was Einstein's miracle year: 1905. Relativity In his miracle year, 1905, he made his 5 theories about relativity. Relativity states that everything in this universe, including space and time, is relative to one another. Theory 1: General Relativity So what is general relativity exactly? General relativity states that space and time are woven into a 4D...
