Female of the Species is a podcast created by Phoebe Cohen, paleontologist and member of the NASA Astrobiology Institute team based at MIT, centered around casual one-on-one conversations between Cohen and fellow women in science that include a “healthy mix of issues facing women in STEM, good solid chit chat, and belly laughs.”
A batch of six episodes is available for download via iTunes. The discussions glide between personal interests and experiences to broader social topics, and each podcast highlights engaging details about the featured guest, who also in turn gives a shout out to other inspiring women, helping to ...

When haze built up in the atmosphere of Archean Earth, the young planet might have looked like this artist’s interpretation — a pale orange dot.
We know little about Earth’s surface temperatures for the first 4 billion years or so of its history. This presents a limitation into research of life’s origins on Earth and also how it might arise on distant worlds as well.
Now researchers suggest that by resurrecting ancient enzymes they could estimate the temperatures in which these organisms likely evolved billions of years ago. The scientists recently published their findings in the journal, Proceedings of the National Academy of Sciences.
“We need a better understanding of not only how life first evolved on Earth, but how life and the ...

The Astrobiology Graduate Conference (AbGradCon) 2017 takes place June 5-9, and the webcast will be viewable at SAGANet.org.
AbGradCon (Astrobiology Graduate Conference) 2017 takes place June 5-9 and will be webcast in its entirety at SAGANet.org.
AbGradCon provides a unique setting for astrobiologically-inclined graduate students and early career researchers to come together to share their research, collaborate, and network. AbGradCon 2017 marks the 13th year of this conference—each time in a different place and organized by a different group of students, but always with the original charter as a guide.
Since it is organized and attended by only graduate students, post docs, and select undergraduates, AbGradCon is an ideal ...

In May, the University of Illinois at Urbana-Champaign profiled Kennda Lynch, postdoc and member of the NASA Astrobiology Institute team at Georgia Tech, tracing how she’s grown from an engineering major at Illinois to become a multidisciplinary researcher in the NASA astrobiology community.
Lynch describes how her emerging fascination with astrobiology combined with opportunity, setting her on a path where she currently researches Mars analog environments found in Utah, work that helps NASA narrow down potential landing sites for the Mars 2020 rover and informs future Mars human missions.

The Astrobiology Science Conference (AbSciCon) took place at the Mesa Convention Center in Mesa, Arizona on April 24–28, 2017.
Sessions were live streamed, and the recordings of AbSciCon 2017 are now available on the NASA Astrobiology YouTube channel.
The theme this year was “Diverse Life and its Detection on Different Worlds.” Mars and icy worlds in our solar system are increasingly recognized as habitable, even as increasing numbers of exoplanets in their stars’ habitable zones have been discovered. The focus is shifting from identification of habitable worlds, to detection of life on these worlds.

Ocean worlds are on planetary scientists’ minds. More and more, evidence rolls in about the potential habitability of ice-covered bodies like Jupiter’s moon Europa or Saturn’s moon Enceladus. The findings point to heat-driven processes in their subsurface oceans that could support life. Scientists are now beginning to wonder: Could the search for life end on one of these icy satellites?
Assuming humanity does land a spacecraft on Europa or Enceladus, any evidence of life it might uncover would receive heavy scrutiny. In a recent report on a possible landing mission to Europa, scientists devoted multiple chapters to discussing ...

NASA scientist, Mary Beth Wilhelm, collects soil samples of preserved ancient microorganisms in the Atacama Desert.
In the above photo, NASA scientist Mary Beth Wilhelm, wearing a cleanroom suit, kneels as she collects soil samples containing microorganisms from Chile’s Atacama Desert, one of the driest places on the planet. She is investigating the preservation of ancient microorganisms on Earth, and what that might mean for future visits to Mars.
“My research shows that the molecules which made up microbes that lived long ago remain well preserved under extremely dry, Mars-like conditions in the Atacama Desert here on Earth,” said Wilhelm, a researcher at NASA’s Ames Research Center in California’s Silicon Valley, and a ...

The NASA Astrobiology Institute was pleased to once again sponsor the Student Poster Competition at the Astrobiology Science Conference (AbSciCon) 2017. As with previous AbSciCon conferences, this event provided motivation, encouragement, and most of all, recognition to astrobiologists of the future.
Thank you to the 85 students and 43 judges that participated in the competition!
The first place poster, with an award of $1000, went to Jacqueline Long from the College of Marine Science, University of South Florida. Her poster was titled: Chlorophyll-f: Earth’s Unseen Production and Habitability Under Red Light.

An artist's conception of planet Kepler-452b, the first near-Earth-sized world to be found in the habitable zone of a star that is similar to our sun.
(Inside Science) — It seems like every day that astronomers discover another possibly habitable world, like Proxima Centauri b, our closest exoplanent neighbor, and TRAPPIST-1f, one of seven recently discovered Earth-sized planets orbiting the same star. But don’t prepare for first contact just yet. It will be exceedingly complicated to figure out whether there’s actually any life or potential for it on such planets, based on new research into our own evolving world.
To a distant observer peering through a telescope, even Earth would not have shown signs of life through most of its past. Despite the fact that our ...

For much of its first two billion years, Earth was a very different place: oxygen was scarce, microbial life ruled, and the sun was significantly dimmer than it is today. Yet the rock record shows that vast seas covered much of the early Earth under the faint young sun.
Scientists have long debated what kept those seas from freezing. A popular theory is that potent gases such as methane – with many times more warming power than carbon dioxide – created a thicker greenhouse atmosphere than required to keep water liquid today.
In the absence of oxygen, iron built up in ancient ...

Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope.
In the papers, Cassini scientists announce that a form of chemical energy that life can feed on appears to exist on ...

Algal bloom in Arctic pond near Tiksi viewed from a Soviet transport helicopter.
It is thought that animal life first arose during the Ediacaran Period, between 635 and 541 million years ago, but these organisms bore little resemblance to the animals we know today. That’s led some scientists to believe that they may not have been animals at all, and instead amounted to failed experiments in multi-cellular evolution.
The remains of these odd creatures, most of which have no evidence of a circulatory or digestive system, largely vanished from the rock record at the start of the Cambrian Period, 541 million years ago. Piecing together a picture of the Ediacaran environment is key ...

Scientists from NASA’s Goddard Center for Astrobiology observed the comet C/2014 Q2 – also called Lovejoy – and made simultaneous measurements of the output of H2O and HDO, a variant form of water. This image of Lovejoy was taken on Feb. 4, 2015 – the same day the team made their observations and just a few days after the comet passed its perihelion, or closest point to the sun.

A trip past the sun may have selectively altered the production of one form of water in a comet – an effect not seen by astronomers before, a new NASA study suggests.
Astronomers from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, observed the Oort cloud comet C/2014 Q2, also called Lovejoy, when it passed near Earth in early 2015. Through NASA’s partnership in the W. M. Keck Observatory on Mauna Kea, Hawaii, the team observed the comet at infrared wavelengths a few days after Lovejoy passed its perihelion – or closest point to the sun.
The team focused ...
