Living Earths: The Astronomical Answer to “Are We Alone?"
About | Information | History | Online | Facts | Discovery
NASA has begun four concept studies of major space observatories that could launch sometime in the coming couple decades. In this fourth in our series on these studies, we discuss the Habitable Exoplanet (HabEx) concept. HabEx is a design for a highly capable observatory with one of the most ambitious and exciting goals: the astronomical search for life-bearing planets in the solar neighborhood. The discovery over the past few years that stars in the Milky Way may each be orbited by at least one planet suggests that among these numerous planetary systems may reside planets similar to Earth and perhaps even harboring life. The HabEx concept is intended to be the astronomical community’s response to an age-old question of humanity, “Are we alone in the cosmos?" Such observations require a large pristine optical space telescope, which will also enable a broad range of unique investigations in general astrophysics. Please join our regular hosts, Tony Darnell, Alberto Conti, and Harley Thronson, as they discuss with Dr. Bertrand Mennesson (NASA JPL), Dr. Scott Gaudi (Ohio State University) and Dr. Rachel Somerville (Rutgers University) the astronomical search for life, exciting new studies in general astrophysics, and the technological advances that will make it possible. =========== Download the DeepAstronomy App and stay current on all content: Android: https://play.google.com/store/apps/details?id=me.dwnld.vrf985&hl=en_GB Apple: https://itunes.apple.com/us/app/deep-astronomy/id1098749154?ls=1&mt=8 Follow DeepAstronomy on Twitter: @DeepAstronomy Like DeepAstronomy on Facebook: https://www.facebook.com/DeepAstronomy/ Like Space Fan News on Facebook: https://www.facebook.com/SpaceFanNews/ Follow DeepAstronomy on Google+ http://google.com/+DeepAstronomy http://google.com/+TonyDarnell We also have a great Google+ Community, come share your thoughts and join the discussion! https://plus.google.com/communities/109849939648748938781

Tony, what happened to the Hubble Hangouts? I really miss them.

I just can't understand how a cellphone camera has specs like this:
CAMERA Primary 12 MP, f/1.7, 26mm, phase detection autofocus, OIS, LED flash, check quality
Features 1/2.5" sensor size, 1.4 µm pixel size, geo-tagging, simultaneous 4K video and 9MP image recording, touch focus, face/smile detection, Auto HDR, panorama
Video 2160p@30fps, 1080p@60fps, 720p@240fps, HDR, dual-video rec., check quality
Secondary 5 MP, f/1.7, 22mm, dual video call, Auto HDR
but a scientist's or scientists' cameras in 2016-2020 are still only able to do what Voyager's camera did in 1990. Come one, scientists are supposed to have the best tech in the world, it needs to improve. -
Each example of a star shade mission that I've seen seems to suggest that the mission pairs a single star shade with a single space telescope. If shade movement is such a time consuming ordeal (not to mention what do you do if the shade fails to deploy correctly), then why is it not the plan to simply send a telescope with a small compliment of them? One would think that this will allow the telescope to look at something worthwhile continuously as each non-observed shade adjusts itself and queues up to be next. This carries the added benefit that if a shade fails, there are backups.
It just seems to me like the advantages of multiple shades would massively outweigh any argument that the project is already physically too big or heavy. Perhaps a single viewing takes so long that moving star shades for a week at a time just feels like a mere moment's wait by comparison? How long do you expect to stare at a single star before you think you understand it well enough to move on to another target? -
Standing in New York and looking at a firefly in LA? Where are those flat earthers when you need em?

Let the xoplanets do for us where we fail in technology in realizing, that planets emit theire own light source .without the deflected sunlight.any lighting strike and hundreds of strikes are the equivalent to a spike in our sensitive light detecting equipment.lighting Is a planets own light and heat source . And the bottom line you get atmosphere readings or atmosphere fingerprints too.and two birds with one stone by a planet doing for us what our limits are failing us.

Tony m'man, you should slit there hangouts up.. in "combustable" bite-sizes ;) like 10-15 mins and realse with a few days inbtween.. People with bad memory like me will listen, and have to rewatch some thing :)
Just like down town man.. -
Missed you guys!
-
Any word from SNC about Dreamchaser? If they are going to continue testing and when a possible launch date may take place?
-
wish i could of seen this live... do they talk about trappist 1?
-
As always awesome Tony, thanks for sharing your love with the universe gathering together expert lovers for us mortal lovers! You know what I mean, keep this way!
-
Only caught a little live, but got the rest now. Great stuff, as usual. Thanks!
-
Great show, and great news at 56:17 , can't wail till you do a show on it
-
Thanks as always!
-
I can't believe That where live
-
Never stop looking up
-
I have this idea that "dark matter" is a heavier gas than "dark energy".
-
Tony, while watching this video I got the idea that "dark energy" is gas.
