Hubble at 25: Oh Planet, What Art Thou?

- This episode of "Hubble at 25" uncovers Hubble's key role in the study of planets beyond our own solar system. Thousands of "exoplanet" candidates have been discovered. While Hubble is not responsible for most exoplanet detections, it is able to examine the chemical compositions of their atmospheres. Since these planets are too far away to ever visit in the forseeable future, analyzing their atmospheres provides critical clues about the existence of life elsewhere in the universe.
We've got a new video in our Hubble's 25th anniversary series. Find out why Hubble matters to the study of planets outside the solar system.
Hi you
Amazing.
Very informative..
Hi
Thanks for the "service" Hubble Space Telescope Very Well Done !!!
I feel like our Scientists are viewing the Universe with such a narrow view. Why is everything compared to what happens and how things happen on the Earth?
I always hear "this planet is too hot to support life..." No, it's too hot to support human life. "a planet must have water to support life..." Again, human life. Who says the Universe plays only by our rules? Even the stats of exoplanets are based on what we know from Earth, again, how can they be so sure the state of a gas, for example, on Earth is the same state in the Universe?
How many times does the Universe have to surprise the Scientists before they broaden their perspective?
Just curious...
I totally agree with you, Life as we know it or life that can exist in what we might call a toxic environment! We as humans as we call ourselves are so arrogant the we think for some strange reason if we can't live there then nothing can! We as humans need to GROW UP. Cheers from John Australia.
2DebbieDoo it's always compared to life on earth because we only know of one place where life, not just "human" life (WTF.?), exists, which is Earth, and all we know about where and what life forms can endure is based on what we observe here.
Hi. Scientist are fully aware that life can develop in various environments but the time it would take to try and look for life everywhere in the universe would be inconceivable. As such scientists narrow their search to where they know for sure that life can develop. Meaning rocky planets found in the goldilocks zone which has the possibility of sustaining liquid water.
They have a lot wrong. Try holoscience.com to find out the electric model of plasma in the universe. The planets around Sol make more sense, the behaviour of comets, nebular structures and all things standard model finds weird are simply explained.
This is amazing!
Very very beauty to see.and philomina loved it i want to kniw more about plz thanks.
At times like this I wish the Overwhelmingly Large Telescope was being built.
slightlytwistedagain Until then, we'll have to make do with the GMT :)
well, i'm quite late on this scene, some comments below are 4 yrs old, but just want to thank Mary Estacion for her presentation.
these days there is so much criticism of NASA (some of it valid, though) its probably (and provably) in order to add
favorable comments as often as possible. At any rate, it is imminent that the new 10 meter mirror will be in place to improve
the telescopic images of such distant constellations. And I want to be effective in encouraging the continued sharing of
these discoveries and images with the publlc. James E. Mortensen
And how you find the transits of a pluto like planet that orbits every 658 years to complete 1 circle
are there other universe s that know about us?
umm i would like to learn more about that rainbow analogy. didnt quite get thr last part of what she meant
lexusfan100 That wasn't an analogy. When you look at the spectrum of light, gasses really do absorb specific wavelengths of light. So if you shine white light through hydrogen gas, for example, you will see several wavelengths of light missing that correspond to the fingerprint of hydrogen gas, so you know the light passed through hydrogen gas. It's not an analogy, that's literally how it works.
We can look at the light coming from a star and see what wavelengths are missing and determine its composition. Then, we can wait until a planet passes in front of it, and see what other wavelengths disappear. When light passes through a planet's atmosphere, the gasses it interacts with also absorbs some of the light, and we can look at the spectrum and determine what gasses it passed through.
Thus, we can determine exactly what gasses comprise a planet's atmosphere.
Podrían alguna vez subtitular en español!!!! Los que no sabemos ingles no existimos?
HOW DID THE HUBBLE GET TO THE NORTHEN PART OF THE MOON?
patrick or paddy you must be a tick irishman , hubble is not on the moon
Who's here in 2011 waiting for James Webb telescope to launch?
👍👍👍👍👍👍👍👍👍👍👍👍👍
and brother.😂
Sie reden und reden und reden. Vollkommener Stuss.
