This week, scientists announced that the James Webb Space Telescope, which among its many talents can analyze the atmospheres of exoplanets, just confirmed the presence of carbon dioxide on a world orbiting a sun some 700 light-years away. It’s the first observation of CO2 in a planetary atmosphere beyond our solar system.
But that discovery, made about a world very unlike our own, is just the first taste of what Webb’s instruments may soon reveal. Astronomers are eager to focus the telescope on planets like Earth, where liquid water, a crucial ingredient for life as we know it, is abundant. In the coming months and years, they will undoubtedly get their chance.
There are a number of promising Earth-like planets Webb could study in the near future, but in a paper published recently in The Astronomical Journal, scientists from the University of Montreal argue they’ve discovered one of the best such candidates yet.

He has also authored academic papers for prestigious peer-reviewed journals, such as Human Brain Mapping and Cognition & Emotion.
If you’re listening to this then congratulations, you’re lucky enough to be alive during the most exciting time in history. We are on the verge of a paradigm shift of unparalleled magnitude. Such a shift occurs when new science forces us to adopt a different overall framework and perspective.
While the planet is too large and hot for life, it could help us study more Earth-like exoplanets.
WASP-39b, a distant gas giant “hot Jupiter,” shows signs of water vapor and carbon dioxide, helping Webb scientists hone in on how to find them on smaller planets.
Researchers have found a new way to convert methane into rocket fuel on Mars — adding crucial flexibility to future astronaut missions to the Red Planet, according to a recent blog post on the University of California, Irvine’s (UCI’s) official website.
Scientists create new way to convert methane into rocket fuel on Mars
Elon Musk and other engineers at SpaceX theorized such a method while searching for ways to combine water from ice on Mars with carbon dioxide to procure enough carbon and hydrogen for methane production.
Why we should be performing interstellar archaeology and how Avi Loeb and his team at the Galileo Project plan to recover an interstellar object at the bottom of the ocean.
“Any chemically-propelled spacecraft sent by past civilizations into interstellar space, like the five we had sent so far (Voyager 1 & 2, Pioneer 10 & 11, and New Horizons), remained gravitationally bound to the Milky Way long after these civilizations died. Their characteristic speed of tens of kilometers per second is an order of magnitude smaller than the escape speed out of the Milky Way. These rockets would populate the Milky Way disk and move around at similar speeds to the stars in it.
This realization calls for a new research frontier of “interstellar archaeology”, in the spirit of searching our backyard of the Solar system for objects that came from the cosmic street surrounding it. The interstellar objects could potentially look different than the familiar asteroids or comets which are natural relics or Lego pieces from the construction project of the Solar system planets. The traditional field of archaeology on Earth finds relics left behind of cultures which are not around anymore. We can do the same in space.“ https://avi-loeb.medium.com/
The goal of the Galileo Project is to bring the search for extraterrestrial technological signatures of Extraterrestrial Technological Civilizations (ETCs) from accidental or anecdotal observations and legends to the mainstream of transparent, validated and systematic scientific research. This project is complementary to traditional SETI, in that it searches for physical objects, and not electromagnetic signals, associated with extraterrestrial technological equipment.
Within this overarching goal, the Galileo Project has defined two specific goals, correlating to our two related areas of study:
To examine the possibility of extraterrestrial origin for unidentified aerial phenomena (UAP), by making observations of objects in and near Earth’s atmosphere, filtering out identifiable objects using AI deep learning algorithms trained on rigorous classification of known objects, and then examining the nature of the remaining data for anomalous characteristics.
Scientists zapped mold spores in a laboratory and concluded that two types of fungus could survive a journey to the moon or Mars.
There are both positive and negative implications about this news, according to a recent statement by the American Geophysical Union (AGU). AGU coordinated the 2019 Astrobiology Science Conference in Seattle, where lead researcher microbiologist Marta Cortesão, a doctoral student at the German Aerospace Center (DLR), will present her research on the mold today (June 28).
Any Xenomorph-fearing ‘Alien’ fan will tell you that sound doesn’t exist in space. The thing is, that’s not completely true.
Back in May, during black hole week, NASA released an eerie sound clip of a black hole showing that space does make a lot of noise, depending on where you look, and how you process it.
“The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we’ve picked up actual sound. Here it’s amplified, and mixed with other data, to hear a black hole!”
The private space firm hopes to send a small probe to Venus by 2023.
Rocket Lab is self-funding a mission to go to Venus in search of signs of extraterrestrial life, a report from *Ars Technica* reveals.
Venus’s surface is a hellish landscape with crushing pressures and temperatures that make it completely uninhabitable. However, some scientists believe the clouds above Venus’ surface may have conditions that are conducive to some forms of microbial life.
Jupiter’s icy moon Europa is an ocean world encased beneath a thick crust of ice — a place where snow floats upward.
The underwater snow forms in the global ocean and travels up though the water to attach to submerged ravines and inverted ice peaks, according to new research. This same phenomenon takes place below ice shelves on Earth — and it may be how Europa builds its ice shell.
The finding, published Monday in the journal Astrobiology, suggested Europa’s ice shell may not be as salty as scientists first thought. Understanding the salt content of the ice crust is crucial as engineers work on assembling NASA’s Europa Clipper spacecraft, which is preparing to launch to Europa in October 2024.
