Earth is on the move. 🌏⬇️➡️

Scientists used InSAR (interferometric synthetic aperture radar) technology on satellites to map the movement of the Kamchatka peninsula after the 8.8 magnitude earthquake offshore on July 29. Displacement measures the shifting of the ground toward or away from the satellite when comparing measurements between two images, usually before and after an event.

InSAR data feeds into models that help scientists define exactly where and by how much a fault slips. This information can be used in tsunami forecasting models, and to help emergency response officials identify the most affected areas after an earthquake.

The recently launched NISAR satellite will provide more consistent and frequent displacement maps. This will allow scientists to track earthquakes in heavily forested areas for the first time, as well as landslides and volcanoes.

This could help predict volcanic eruptions, like that of Krasheninnikova. The long-dormant volcano erupted 5 days after the earthquake, but showed displacement after the earthquake, prior to eruption.

One of the most promising candidates for extraterrestrial life may lie just 40 light-years away.

Astronomers studying TRAPPIST-1e—one of seven known planets orbiting the red dwarf star TRAPPIST-1—have found encouraging signs that it may host a life-supporting atmosphere.

Using data from the James Webb Space Telescope (JWST), a team of researchers has detected hints that the planet could have a nitrogen-rich atmosphere, potentially with traces of methane—a combination that resembles Earth’s air and raises hopes for habitability.

TRAPPIST-1e sits in the middle of its star’s “Goldilocks zone,” where temperatures could allow water to remain liquid. However, detecting atmospheres around planets orbiting red dwarfs is especially difficult because the star’s own light can mimic chemical signatures like water or methane.

To overcome this, the team spent years developing new models to isolate atmospheric signals from starlight interference. Their efforts have revealed subtle features in the light data that, if confirmed, suggest the presence of a life-friendly atmosphere.

Still, caution prevails. With only four JWST transits recorded so far, the evidence is far from conclusive. The team is planning 15 more observations to reduce uncertainties and confirm whether the signals truly originate from the planet’s atmosphere and not from the star itself. If a nitrogen-rich atmosphere is validated, the next step will be to search for carbon dioxide, methane, and determine whether conditions on the surface could allow for liquid water—a key ingredient for life as we know it.

The TRAPPIST-1 system, discovered in 2016, has long excited astrobiologists, especially because three of its planets lie within the habitable zone. But until now, observations of two other potentially habitable planets had failed to reveal any atmospheres. That’s why this new data from TRAPPIST-1e is so important—it’s the first truly hopeful sign in the system.

Our package has been delivered 📦🚀

NASA’s Northrop Grumman CRS-23 mission arrived at the International Space Station today, Sept. 18, carrying a cutting-edge Zero-Boil-Off Tank (ZBOT) experiment led by our center!

ZBOT-NC will study how non-condensable gases affect tank pressure in microgravity. Data from the experiment could help us develop more efficient ways to store spacecraft fuel, advancing NASA Technology that will be essential for long journeys to the Moon and Mars.

This is the second in a trio of ZBOT experiments, the first of which (pictured here 📸) launched to the space station in 2017.

We are well aware about Ohm's law, as, it is the simplest constitutive relation for an ordinary . But, what about ? For that we have the London Equations. They are the simplest meaningful description of superconducting phenomena, and form the genesis of almost any modern introductory text on the subject. The equation are developed by two London brothers and one of them is our "scientist of the day" today.

It's the birthday of , the man who devised the first quantum mechanical treatment of hydrogen molecule - -

(Scientist of the Day - 07 March)

London's early work with on chemical bonding is now treated in any textbook on physical chemistry. This paper was the first to properly explain the bonding in a homonuclear molecule such as H2. It is no coincidence that the Heitler-London work appeared shortly after the introduction of quantum mechanics by and , because quantum mechanics was crucial in their explanation of the covalent bond.

With his brother , he made a significant contribution to understanding electromagnetic properties of superconductors with the London equations and was nominated for the Nobel Prize in Chemistry on five separate occasions.

He coined the expression "dispersion effect" for the attraction between two rare gas atoms at large distance from each other. And today, this attraction is often referred to as "London force".

He was the first theoretical physicist to make the fundamental, and at the time controversial, suggestion that superfluidity is intrinsically related to the Einstein condensation of bosons, a phenomenon now known as condensation.

London was also one of the early authors (including Schrödinger) to have properly understood the principle of local gauge invariance in the context of the quantum mechanics.
