Why Neil deGrasse Tyson and Emily Rice Think You Should Pay Attention to Low-Mass Stars
Could we find life around low-mass stars? Neil deGrasse Tyson and comedian Chuck Nice find out why life might be more likely around low-mass stars, what makes brown dwarfs, galactic archeology, and more with astronomer Emily Rice.
Where did the name “brown dwarf” come from? Learn about when brown dwarfs were first discovered and astronomer Jill Tarter’s research on them. We discuss star classification, why the letters are so out of order, and how brown dwarfs are relevant to the field of exoplanets. What is the difference between a brown dwarf and a low-mass star? Find out what the cutoff is for thermonuclear fusion and how deuterium can help low-mass stars fuse a little.
What is the difference between a brown dwarf and a hot Jupiter? Do we know how brown dwarfs are formed? What is the largest dwarf star ever discovered? Learn about age-mass degeneracy and how low-mass brown dwarfs could actually be old high-mass brown dwarfs. Discover the Sun’s tachocline and how the brown dwarve’s magnetic field may operate differently.
What happens when two brown dwarfs collide? What the heck is a blue straggler? Find out about the lifespan of brown dwarfs, galactic archeology, and metallicity. How do you tell the age of different low-mass stars? What would it take to capture a direct image of an exoplanet? We discuss the Trappist-1 System, the Goldilocks zone, and good candidates for Earth-like planets. Plus, a cosmic perspective on the importance of space exploration.

    Its the same here ( Germany), 25°C is about perfect. 30°C+ is hot, 35°C+ too hot. -10°C is about the point where it gets fing cold. 0°C+- is typical winter. So its the same feeling. When we hear 100°F we think about saunas or cooking water while its just "too hot" in reality.

    Celsius is easy. Below 10° grab a jacket. Below 20° get a coat. Over 25° get a t shirt. Over 30° it's hot. Over 35° forget working. Over 38° stop everything but emergency work.

    Camera obscura. I've worked as a photographer/projectionist and you're absolutely right Neil. Pinhole aperture makes things close up in focus and will only have focus to infinity when a long exposure is applied which would have bleached the photographs white from the extremity of sunlight without an atmosphere. These people will never give it up. They want conspiracy with everything and what enables them is about half the theories are in fact conspiracy so they say everything is a conspiracy.

    Show me an example where we use a term with its adjective but as general not calling it that term. A dwarf planet is a planet . "Planet" is the main term and underneath we have different types of planets. Same like stars ... So why is it that we do not accept Pluto as a planet orbiting the sun in our solar system. Planet is a planet regardless of its type. A human is human regardless of its race religion color or type.

    Society is written and ruled by those who benefit from the 'free will' theory. Therefore, we believe it. This funnily enough, disproves the notion of it -- as your brain is programmed from birth that you have this 'free will' which warps your mental state.

    It feels better for weather because 100 is us. (Actually Daniel Farenheit meant 100 to be human body temperature. He must have had a fever that day.) So it makes a percentage scale of how the temperature compares to us.

    The person I would most like to bring back to life is Mohandas Karamchand Gandhi, popularly known by his unofficial title of The Mahatma, which means Great Soul. Unfortunately he was cremated then his ashes were cast into the holy river Ganges, so resuscitation in his case is unlikely to be successful.
