Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have come from the outer solar system, i.e., beyond Jupiter. For a long time, material from the outer solar system was considered necessary to bring volatile components such as water to Earth. Accordingly, there must also have been an exchange of material between the outer and inner solar systems during the formation of Earth. But is that really true?
Planetary scientists Paolo Sossi and Dan Bower, from ETH Zurich, compared existing data on the isotopic ratios of a wide range of meteorites, including those from Mars and the asteroid Vesta, with those of Earth. Isotopes are sibling atoms of the same element (same number of protons) that have a different mass (different number of neutrons).
The researchers analyzed this data in a new way and arrived at a surprising conclusion: the material that makes up Earth originates entirely from the inner region of the solar system.
Researchers at the National Institute of Standards and Technology (NIST) have developed a new way to package photonic integrated circuits—tiny chips that convey information using light instead of electricity—so they can survive and operate in extreme environments, from scorchingly hot industrial settings to ultracold vacuum chambers and the depths of outer space.
“Our study marks a major step toward bringing the speed and efficiency of photonics into environments where conventional semiconductor chips powered by electric current and photonics chips packaged using traditional methods have not been able to operate,” said NIST physicist Nikolai Klimov, who led the project. The results were just published in Photonics Research.
How can scientists determine if exoplanets orbiting M-dwarf stars are habitable? This is what a study recently presented at the 247th Meeting of the American Astronomical Society hopes to address as a team of scientists investigated how stellar activity from M-dwarf stars could influence planetary habitability. This study has the potential to help scientists to narrow constraints for conditions regarding finding life beyond Earth.
For the study, the researchers explored a unique type of M-dwarf star called a complex periodic variable (CPV), which are young M-dwarf stars that have been observed to have periodic decreases in brightness. While brightness dimming is often attributed to a planet passing in front of the star, or even gas and dust, astronomers were perplexed regarding this particular phenomenon. Their initial hypothesis was the brightness dips resulted from bright and dark regions on the star’s surface.
After significant analysis, the researchers discovered that the brightness dips were caused by a “donut” of super-heated gas called plasma, which all stars are made of, trapped within the star’s magnetic field. As the donut rotated around the star, it caused periodic dips in brightness. Along with estimating that approximately 10 percent of M-dwarf stars could be designated as CPVs, they also note this unique stellar could help gain greater insight into how it influences planetary conditions, which the researchers dubbed “space weather stations”

• JEPA / H-JEPA: avoids predicting every single pixel (too expensive) and rather predicts in latent space. H-JEPA adds hierarchy — short term details vs long term planning ie. how humans actually learn.
• I-JEPA: built for very efficient vision models. Masks image patches and predicts the semantics and in doing so bypasses heavy compute of traditional autoencoders.
• MC-JEPA & V-JEPA: both of these are built for videos. MC-JEPA separates content (what an object is) vs motion (how it moves). V-JEPA masks video features with no text labels making it perfect of action tracking at scale.
• Audio-JEPA: filters out background noise by treating sounds like visuals.
• Point-JEPA & 3D-JEPA: used primarily in AVs. Uses LiDAR point clouds & volumetric grids.
• ACT-JEPA: filters out real world noise to learn manipulation tasks efficiently via imitation learning.
(SRI) will organize a high-level side event during the COPUOS Legal Subcommittee on 16 April 2026 at UNOOSA (Vienna), proposed and convened by Dr. Gülin Dede, titled “Operationalising Space as a Cross-Cutting Enabler of Sustainable Development: Perspectives on an Emerging 18th SDG Articulation.”
The session will bring together legal, policy, industry, and Global South perspectives to examine how outer space is evolving from a sectoral domain into a critical enabling infrastructure for the 2030 Agenda, while simultaneously requiring stewardship as an environment in its own right.
Positioned as an early contribution to shaping how space sustainability is framed within the broader UN system, the event will also be broadcast by the United Nations, extending its reach beyond the room to a global audience.

This video tests three real generation-ship proposals against five brutal constraints: gravity, radiation, closed-loop life support, cultural continuity across 400 years, and the selection problem — choosing who gets to go. We break down Chrysalis (a 58 km modular ship that sheds stages like a rocket), Proximum (a civilization carved inside an asteroid), and WFP (a self-assembling micro-city based on MIT research). Along the way we confront governance without a homeworld, genetic bottlenecks, generational memory loss, and why shared rituals might matter more than engine specs. The answer isn’t one ship — it’s three radically different philosophies of what it means to be human in deep space.

I do the relativistic math behind Project Hail Mary — time dilation, mass ratios, coast phases, and the relativsitic rocket equation with astrophage. How long would it take to reach Alpha Centauri, Tau Ceti, Betelgeuse, Andromeda, and the edge of the observable universe under constant 1.5G acceleration? We also look at Andy Weir’s mass ratio mistake, the astrophage infection range problem, and visualize the spread using the AT-HYG stellar catalog. Includes a interactive relativistic travel calculator on my website.
