How Do Scientists Find Habitable Exoplanets ? 🤔 w/ Professor Brian Cox 🤯

The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy. Today, this process uses instruments with a grating that spreads out the light from an object by wavelength.

Brian Edward Cox is an English physicist and former musician who is a professor of particle physics in the School of Physics and Astronomy at the University of Manchester[2][3] and The Royal Society Professor for Public Engagement in Science.[4] He is best known to the public as the presenter of science programmes, especially BBC Radio 4’s The Infinite Monkey Cage and the Wonders of... series[5][6] and for popular science books, such as Why Does E=mc²? and The Quantum Universe.

More. MORE. MOOOOREEE! Seriously, where's part 2 link

[retired]

Hope he does a presentation in the Eastern US soon.

[Thathumanoverthere]

I wish i could be a student in his lectures when i was at university. It would have been amazing

[JnManuelAG]

His English accent is magnificent. That and the way he talks makes me want to hear him for hours

[richardmayne]

Cut out the best part my stoned arse was just becoming increasingly intrigued 😂😂

[Pepper_Jack]

I was wondering about this a couple of days ago. Thanks for the answer to a question that I didn’t even ask

[andrewjuarez]

What a step forward in light and sight! 😮

[stollifa]

So that found out Fraunhofer. One of a genius in building teleskopes. For making highly accurate crosshairs he was fetching special spiders and made them to spin single hairs he then used building his highly precise crosshairs.

[VishalSingh-gtdx]

! 🤯 I always wondered that how do they know if a exoplanet is habitable.

[Adam_Tilbrook]

What I wouldnt give to be able to go to one of Brian's presentations.

[TheTrentReznor]

Doppler effect, and can tell w/spectrograph composition of atmosphere- boom goes the 🧨

[TheWorldBelow]

Those other folks in Outer Space may have much groovier themes with which to play at absorbing light.

[venkybabu]

Why elements are radioactive from fission because it took a long time for fusion.

[lukem]

They're so famous, I'm not even going to mention them.

[DrDeuteron]

But the reradiate at the same frequency they absorb, so where’s that light go?

[keithandnatani]

So different elements go at different rates

[jeif]

I dont know nor understand 90% of what he is saying. But somehow, I'm compell go listen thru the whole thing..

[thatdrummerdude]

I was Just wondering how we Knew that the sun has helium

[NopeP]

Flat earthers got nothing when talking against this man.

[BBCBOY]

Can we get a new sad song now? Snowfall is so overdone man
