NASA: Exploring the Universe and Beyond

In this video, you will learn about NASA’s Parker Solar Probe, a spacecraft that is flying closer to the sun than ever before. You will discover how the probe uses gravity assist from planets, especially Venus, to change its orbit and get closer to the sun. You will also find out what are some of the records and achievements that the probe has set so far in its mission, and what are some of the mysteries and phenomena that it is trying to measure and understand in solar physics. You will also see some amazing images and data of the sun and its surroundings, collected by the probe’s instruments. This video will give you a glimpse into the secrets of the sun and its effects on the solar system, and how NASA’s Parker Solar Probe is revealing them to us.

Black holes are the most mysterious and fascinating objects in the universe. They are so massive and powerful that they can swallow anything, even light itself. Nothing can escape from their gravity, not even time. But how did these black holes form and grow? And how do they affect the evolution of the universe? In this video, we will explore two main types of black holes: primordial black holes and supermassive black holes. We will also show you some of the latest discoveries and observations that shed light on their origin and growth, using various telescopes such as JWST, Chandra, Hubble, and ALMA. We will also highlight some of the controversies and challenges that surround this topic, and how they could affect our view of the origin and evolution of black holes and galaxies. So join us on this journey into the dark and mysterious world of black holes.

Today, the Artemis II astronauts got their first look at the Orion spacecraft slated to fly them around the Moon in late 2024. The Artemis II crew consists of NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen. Artemis II is the first crewed mission on our path to establishing a long-term human presence on the Moon, and is the first mission with astronauts to the Moon's orbit in more than 50 years. The approximately 10-day flight test will launch on the powerful Space Launch System rocket, prove the Orion spacecraft’s life-support systems, and validate the capabilities and techniques needed for humans to live and work in deep space.

In this episode, you will learn about a fascinating topic: dark matter annihilation at the center of the Earth. Dark matter is a mysterious substance that makes up most of the matter in the universe, but has not been directly detected yet. However, some astronomers have been searching for signs of dark matter colliding with itself and producing neutrinos, which are tiny particles that can travel through the Earth without being stopped by anything. To do this, they have been using a giant detector called IceCube, which is a neutrino observatory located at the South Pole. IceCube has been looking for neutrinos from dark matter annihilation for seven years, and it has found some intriguing hints of a possible signal. But it is not sure yet if this signal is from dark matter or from something else. This could be a breakthrough discovery, or a false alarm. You will find out more about this exciting research and what it means for our understanding of the cosmos.

*How old is our universe?* This is one of the most fundamental questions in cosmology, and we thought we had the answer: about 13.8 billion years. But what if we are wrong? What if our universe is twice as old as we thought, and that changes everything we know about its history and evolution? In this video, we will explore a shocking new discovery that suggests that our universe is 27 billion years old, and what it means for our understanding of the cosmos. We will also look at some of the mysteries and puzzles that led scientists to question the age of the universe in the first place, and how they used a new model to solve them. We will talk about how the James Webb Space Telescope has discovered early galaxies that seem to be far too advanced for their age, and how this challenges our theories about the origin and evolution of galaxies. We will also discuss how this new study can affect some of the fundamental questions and mysteries that we have about the universe, such as what happened before the Big Bang, what is the shape and size of the universe, and what is the destiny and fate of the universe. This video is based on a new study by Rajendra Gupta, a physicist from the University of Ottawa, who claims that our universe is not 13.8 billion years old, but 27 billion years old. His study is published in Physical Review D in November 2021. If you are interested in learning more about this topic, please check out the links in the description below.
