Fans of perovskite solar cell technology have been promising the moon, and stakeholders are increasingly confident that it will deliver. Among them is Toyota, which has just tapped its Woven Capital branch to put down a 5.5 billion yen stake in the perovskite solar startup EneCoat Technologies. If you’re thinking the solar-powered electric car of the future is coming, that’s a good guess, because EneCoat lists mobility applications among its areas of focus.

A team of scientists from Montana State University has provided the first experimental evidence that two new groups of microbes thriving in thermal features in Yellowstone National Park produce methane—a discovery that could one day contribute to the development of methods to mitigate climate change and provide insight into potential life elsewhere in our solar system.

Scientists using the James Webb Space Telescope have discovered one of the oldest and coldest-known exoplanets by directly imaging its host star (see image, below).

It’s the first time JWST has imaged an exoplanet that had not already been imaged using a ground-based telescope.

Exoplanets are planets that orbit a star other than our sun. Almost all of the 5,000 known exoplanets have been discovered indirectly using the transit method, detecting changes in the light of a star as a planet crosses in front of its disk.

“This discovery is exciting because the planet is quite similar to Jupiter — it is a little warmer and is more massive but is more similar to Jupiter than any other planet that has been imaged so far,” said Dr. Elisabeth Matthews.

How cold are exoplanets? This is what a recent study published in Nature hopes to address as a team of international scientists investigated Epsilon Indi Ab, which is located approximately 12 light-years from Earth and whose radius is slightly larger than Jupiter and just over three times as massive. What makes this study unique is this it was observed using the direct imaging method, which has only been conducted on approximately 25 exoplanets to date, and could help astronomers better understand the formation and evolution of not only Epsilon Indi Ab, but countless other exoplanets, as well.

Discovered in 2019, astronomers previously hypothesized the planetary properties of Epsilon Indi Ab based on data at the time. For this recent study, astronomers used JWST’s Mid-Infrared Instrument (MIRI) and its coronagraph to directly image Epsilon Indi Ab, revealing much different properties while also identifying the planetary temperature of approximately 35 degrees Fahrenheit, making Epsilon Indi Ab the coldest exoplanet to date. Additionally, Epsilon Indi Ab was also found to have high metal contents within its atmosphere, specifically a high carbon-to-oxygen ratio.

A very relevant subject for research.

The world appears to contain diverse kinds of objects and systems—planets, tornadoes, trees, ant colonies, and human persons, to name but a few—characterized by distinctive features and behaviors. This casual impression is deepened by the success of the special sciences, with their distinctive taxonomies and laws characterizing astronomical, meteorological, chemical, botanical, biological, and psychological processes, among others. But there’s a twist, for part of the success of the special sciences reflects an effective consensus that the features of the composed entities they treat do not “float free” of features and configurations of their components, but are rather in some way(s) dependent on them.

Consider, for example, a tornado. At any moment, a tornado depends for its existence on dust and debris, and ultimately on whatever micro-entities compose it; and its properties and behaviors likewise depend, one way or another, on the properties and interacting behaviors of its fundamental components. Yet the tornado’s identity does not depend on any specific composing micro-entity or configuration, and its features and behaviors appear to differ in kind from those of its most basic constituents, as is reflected in the fact that one can have a rather good understanding of how tornadoes work while being entirely ignorant of particle physics.

Mosses are among Earth’s great terraformers, turning barren rock into fertile soils, and now a team of scientists is proposing these non-vascular plants could do the same on Mars.

Whether we should introduce life from Earth onto our red neighbor is another question – we don’t have a great track record with this on our own planet.

But if we decide it’s worth messing with soil on Mars to create a second home for us Earthlings, ecologist Xiaoshuang Li and colleagues at the Chinese Academy of Sciences have a candidate that they think should do just the trick.

NASA’s Juno orbiter has returned its latest batch of images of giant Jupiter, which are as impressive as ever.

Despite suffering from radiation damage earlier this year, its JunoCam camera—boasting just a two-megapixel resolution—continues to take and return arresting images of the planet’s cloud tops.

In recent months, Juno has been sending back images of Io, the closest of Jupiter’s large Galilean moons (Io, Europa, Callisto and Ganymede) and the most volcanic world in the solar system.

NASA is celebrating the 25th anniversary of its Chandra X-ray Observatory launch by sharing never-before-seen photos of the largest known spiral galaxy in the universe.

The Chandra X-ray observatory was launched on July 23, 1999. Since then, it has scoured the universe to look for X-ray emissions from exploded stars, clusters of galaxies and more, according to NASA. The observatory returns data to the Chandra X-ray Center at Harvard University’s Smithsonian Astrophysical Observatory.

To most people, the sun is a steady, never-changing source of heat and light. But to scientists, it’s a dynamic star, constantly in flux, sending energy out into space. Experts say the sun is now in its most active period in two decades, causing potential disruptions to radio and satellite communications. John Yang speaks with Bill Murtagh of NOAA’s Space Weather Prediction Center to learn more.
