NASA's TESS Exoplanet Satellite Sees First Light

NASA's Transiting Exoplanet Survey Satellite (TESS) saw its first light and is now open for science! TESS will make a two-year survey of the entire sky to search for nearby extrasolar planets (or exoplanets) around nearby stars that can be followed-up for further study with NASA's James Webb Space Telescope (JWST).

I love how fast you are at reporting current events in space news. Thanks for all the hard work. Its very much appreciated and enjoyed.

[kevinflynn]

Very interesting, thanks! Can't wait to see what real estate appears in the "neighborhood"! 👍✌

[ThisSingleMom]

Definitely learned something. Your channel is refreshing!

[miriamhavard]

I am just SO liking I feel like a kid again! 📺📚📓👧🌌🚀🔭

Great to meet you today. Looking forward to getting to know you better. Love what I've seen so far.

[nicosmind]

There's nothing specific I'm looking forward to from TESS, but the fact it picks out planets for follow up missions is exciting. What I really can't wait for is when we can get the spectra from exoplanets, and start cataloguing planets like that.

Very interesting friend. Thanks for sharing such a valuable knowledge 🙏

This is a great video indeed. Big Thanks

One gripe I have is that TESS is limited to detecting planets with short periods because it only observes one sector for 27 days. Hopefully, after the primary mission is over TESS is made to stare longer at each sector in order to detect planets with Earth-like orbits.

[PhillProbst]

I’ve yet to hear anyone address the fact that the transit method can only find planets in Star systems whose orbital plane is oriented edge on from our perspective. Assuming a random distribution of orbital plane orientations, a quick, back-o-the-envelope, calculation suggest that only 1/648, 000 (or of the observed stars would offer the possibility of planet detection. So, if we find planets at this rate or higher, it would imply that all stars have planets.

TESS has found two new exoplanets one with a year that's only 11 hours long JWST has a lot of work to do IF it gets to orbit
great video criss thanks for the TESS update like the pro version of telescope talk hangout with tony i hope you guys keep it going for many years to come appreciate your work
cheers

I was shocked by the image that was full of stars....how many stars did the TESS watched in Southern Hemisphere?

[eaglevp]

Wow what brilliant content have supported your channel hit the like button and pressed the bell also shared on my twitter account

[prettysweettraveller]

@S.E Sander you also like watching stars, celestial bodies, galxy and the likes? wow

[MrAqr]

2:32~ Nice rhyming! If only you didn’t mention it yourself.

[MrAqr]

I hope α-Centauri has planets suitable for life.

I'm looking forward to the possibility (should be likely) of TESS returning evidence for E.T. civilisations (that is, if the US Govt. will release it).

[adamforest]

Why haven't they released anymore videos/ pictures theirs just the one with the comet which is insane but that's it!???

[CyberwizardProductions]

wish you'd mentioned the planethunters project on Zooniverse. We could use help with the images

[bbbl]

So will TESS be able to detect the planets in the LMC & SMC?
