“Our Milky Way galaxy is only one of perhaps a trillion galaxies...These observations present us with a cosmos of billions of trillions of stars & likely thousand times as many possible worlds.” Cosmos: Possible Worlds, Ann Druyan @NatGeo @NatGeoBooks @Cornell #COSMOS #COSMOSCSIpic.twitter.com/Y4TUR3dZyp
We were inspired by the new #COSMOS book to wonder about all worlds in our vast universe.
Now you will hear from some of our fellows at the Carl Sagan Institute (@CSInst) on the diversity of worlds already discovered in our Galaxy. Imagine what else is out there!

"Proxima Centauri b is one of the few exoplanets that a human-built spacecraft may be able to visit in our lifetimes." Dr. Mason Peck (Professor of Aerospace Engineering, @Cornell University, @CSI fellow) #COSMOSCSI #COSMOS #CSIExoplanets 1/4pic.twitter.com/3w87AHqyHm
"The goal would be audacious, but every day technology research is bringing that future closer to the present: new materials, communications approaches, and spaceflight navigation are all difficult challenges." Dr. Mason Peck #COSMOSCSI #COSMOS #CSIExoplanets 2/4
"But the prospect of an up-close-and-personal measurement [of Proxima Centauri b] inspires us to take them on." Dr. Mason Peck #COSMOSCSI #COSMOS #CSIExoplanets 3/4
Dr. Mason Peck is on the engineering faculty at @Cornell University, where his research & teaching focus on Aerospace Engineering and Systems Engineering. Learn more about Dr. Peck here: https://www.engineering.cornell.edu/faculty-directory/mason-peck … #COSMOSCSI #COSMOS #CSIExoplanets 4/4
"HD 80806b was the first planet that was discovered to have an extremely eccentric orbit...greater than 0.9. I was initially amazed that a planet could exist on such an eccentric orbit."

"I find it naturally curious to wonder about the existence of planets around exotic objects such as pulsars." Akshay Suresh (Graduate student, Department of Astronomy, @Cornell, @CSInst fellow) #COSMOSCSI #CSIExoplanets #COSMOS 1/4pic.twitter.com/AtNKFl1Tym
"Given the limited sample of pulsar planets known today, the initial discovery of multiple planets around pulsar B1257+12 is highly remarkable. This discovery predates our 1st finding of an exoplanet around a main-sequence star." Akshay Suresh #COSMOSCSI #CSIExoplanets 2/4
"This discovery predates our first finding of an exoplanet around a main-sequence star. Yet, we know very little about planets around pulsars." Akshay Suresh (@suresh_akshay1) #COSMOSCSI #CSIExoplanets #COSMOS 3/4
Akshay Suresh is a graduate student in the Astronomy department at @Cornell. His research is focused on adio transients, such as fast radio bursts, SETI, and exoplanets. Learn more: https://astro.cornell.edu/akshay-suresh 4/4
"51 Eri b is one of the most exciting directly imaged objects to date." Dr. Dmitry Savransky (Assistant Professor, Mechanical and Aerospace Engineering @CornellMAE @Cornell, @CSInst fellow) #COSMOSCSI #CSIExoplanets #COSMOS 1/3
"This planet we’ve found is young - only about 20 million years old. These discoveries close the loop for theorists on how planetary systems develop." Dr. Dmitry Savransky https://news.cornell.edu/stories/2015/08/savransky-savors-role-major-exoplanet-discovery … #COSMOSCSI #CSIExoplanets #COSMOS 2/3

"OGLE-2013-BLG-0723LBb is one of the most interesting planets yet discovered...or is it? This object orbits around a brown dwarf which in turn orbits around a small star." Jack Madden (@Astro_Madden, Graduate Student, Astronomy Department, @Cornell) #COSMOSCSI #CSIExoplanets 1/6pic.twitter.com/oHdKKx3Y9s
"A brown dwarf technically isn’t a star but it also isn’t a planet, so is OGLE-2013-BLG-0723LBb a planet or a moon?" Jack Madden (@Astro_Madden) #COSMOSCSI #CSIExoplanets 2/6
"This object was discovered in 2013 using one of humanity's greatest successes, our understanding of gravity...through the method of gravitational microlensing." Jack Madden (@Astro_Madden) #COSMOSCSI #CSIExoplanets 3/6
"With a mass smaller than Earth it is very likely to be rocky but the surface temperatures could be as low as -230C & the day side would never get much brighter than standing under a street lamp on a dark night here on Earth." Jack Madden #COSMOSCSI #CSIExoplanets 4/6
"The life journey of this planet (OGLE-2013-BLG-0723LBb) might also be very interesting." Jack Madden (@Astro_Madden) #COSMOSCSI #CSIExoplanets 5/6
Jack Madden is a 6th year Ph.D. student in the Department of Astronomy at @Cornell working with Dr. @KalteneggerLisa on modeling the climates of potentially habitable exoplanets.

“All [the planets] have such wonderfully unique stories of their own. But if I had to narrow it down to 2 worlds that exemplify the diversity of exoplanets out there, it would be Europa and Titan." Dr. Azul Pinochet-Barros (@AzulPinoba, Microbiology, @Cornell) #CSIExoplanets 1/7pic.twitter.com/cpxF1q3Fio
“As a microbiologist I have come to realize that life always finds a way. Our very own Pale Blue Dot is home to a wide range of extreme, hostile environments wherein we generally would not think life to be possible. ” Dr. Azul Pinochet-Barros (@AzulPinoba) #CSIExoplanets 2/7
“Europa (with its active, liquid water subsurface ocean) and Titan (a dense [atmosphere] and ice world with surprising Earth-like features) have extreme environments that are literally beyond this world.” Dr. Azul Pinochet-Barros (@AzulPinoba) #CSIExoplanets 3/7
“However, within these hostile conditions, they each possess particular qualities that leave a sliver of hope for their potential to harbor life, or at least the precursors for it.” Dr. Azul Pinochet-Barros (@AzulPinoba) #CSIExoplanets 4/7
“There is still a lot that we do not understand about these systems." Dr. Azul Pinochet-Barros (@AzulPinoba) #CSIExoplanets 5/7
But with further exploration coupled with our scientific inquisitiveness, who knows what answers we will find in Titan, Europa, and beyond? I for one, cannot wait to find out.” Dr. Azul Pinochet-Barros (@AzulPinoba) #CSIExoplanets 6/7
Dr. Azul Pinochet-Barros is a PhD student in the Microbiology Department at @Cornell.
