—BBC Sky at Night: “We Were Truly Astonished” – Astronomers Say Earth Formed from the Same Material as Mars“

Planetary scientists say they’ve taken a step closer to solving the mystery of where the material that formed Earth comes from. While Earth resides in the inner Solar System with Mercury, Venus and Mars, it’s been proposed that up to 40% of the material that formed our planet came from the outer reaches, beyond the orbit of Jupiter. But a new study looking at the chemistry of meteorites has found that Earth is likely made entirely from the inner Solar System. In particular, Earth’s make-up is strikingly similar to that of Mars and Vesta, one of the biggest objects in the asteroid belt.

—SciTechDaily: “Interstellar Comet 3I/ATLAS Came From a Place Nothing Like Our Solar System“

A comet from beyond our solar system is giving astronomers a rare look at how alien planetary systems may form under conditions very different from those that shaped our own cosmic neighborhood. The object, called 3I/ATLAS, was discovered less than a year ago as it traveled through our solar system. Although scientists still do not know exactly where it originated, new research led by the University of Michigan suggests the comet formed in an extremely cold region of space…“Our new observations show that the conditions that led to the formation of our solar system are much different from how planetary systems evolved in different parts of our galaxy,” said Luis Salazar Manzano, lead author of the study and a doctoral student in the U-M Department of Astronomy.

—New York Times: “U.S.-China Rivalry Reaches South American Skies“

In the foothills of the Argentine Andes, the enormous Chinese radio telescope sits in one of the world’s premier stargazing locations, surrounded by vast, undulating mountain ranges and beneath skies untouched by light pollution. It is also on the opposite side of the planet from Beijing, offering China a window on the half of the heavens it would not otherwise see. But the Chinese telescope at the site, the Cesco observatory in San Juan Province, picks up no signals. After the U.S. government repeatedly pressed them on the issue, the Argentine authorities stopped the project’s completion. Lacking key parts, the telescope now sits dismembered, its gigantic antenna pointing blindly at the sky.

—Rocket Lab: “Rocket Lab Completes Second Dedicated Launch for Japan Aerospace Exploration Agency (JAXA)“

The “Kakushin Rising” mission lifted off from Rocket Lab Launch Complex 1 in New Zealand at 3:09 p.m. NZT to successfully deploy eight spacecraft for JAXA’s Innovative Satellite Technology Demonstration Program that included educational small sats, an ocean-monitoring satellite, a demonstration satellite for ultra-small multispectral cameras, and a deployable antenna packed tightly using origami folding techniques that can unfurl up to 25 times its size. “Kakushin Rising” builds on the success of Rocket Lab’s first dedicated launch for JAXA that took place in December 2025, which saw Electron deploy the RAISE-4 spacecraft that demonstrated new aerospace technologies developed by several companies, universities, and research institutions throughout Japan.

—NASA: “Progress 95 Cargo Craft Docks to Station with Food, Fuel, and Supplies“

The uncrewed Roscosmos Progress 95 spacecraft docked to the aft port of the International Space Station’s Zvezda module at 8 p.m. EDT Monday. The spacecraft is delivering about three tons of food, fuel, and supplies for the Expedition 74 crew. It will remain docked to the orbiting laboratory for about six months before departing for a planned destructive re-entry into Earth’s atmosphere to dispose of trash loaded by the crew.

—National Radio Astronomy Observatory: “3I/ATLAS Contains 30X More Semi-Heavy Water Than Comets In Our Solar System“

New observations of the interstellar comet 3I/ATLAS include the first measurement of the abundance of deuterated water relative to ordinary water in an interstellar object. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered that the interstellar comet 3I/ATLAS is made of an astonishingly high ratio of semi-heavy water relative to water, indicating that its system of origin likely formed under conditions far colder than our own.

—Astronomy.com: “Could this Telescope Find Life on Alien Worlds?“

The ExoLife Finder (ELF) looks like no telescope ever built. A spectacular crown of 15 five-meter mirrors perches atop a sprawling metal lattice, resembling petals on a 10-story-tall mechanical flower — more sculpture than observatory. It is a fundamentally new type of telescope, one that its designers say could discover life on Earth-like planets beyond our solar system. The radical design is the brainchild of astrophysicist Jeff Kuhn of the University of Hawai‘i. For now, it exists only in renderings. To build it, Kuhn and the team he’s assembled must first develop and perfect techniques and technologies never before used in astronomy.

—EarthSky: “Walking Robots on Mars Could Speed Up Life Search“

Robotic rovers have become the go-to way to explore our neighbor planet, Mars. And they’ve been super successful. But they’re also big, heavy and slow. They have to move carefully across the rocky and sandy terrain of Mars. Plus, communication delays between the rovers and Earth – and data transfer limitations – also affect their missions. Is there a better way? On March 31, 2026, researchers in Switzerland and the Netherlands announced a new idea: walking Mars robots. The research team said these robotic explorers would be semi-autonomous. This means they wouldn’t need regular assistance from humans back on Earth. And, their makers say, they could explore their surroundings – on both Mars or the moon – faster than rovers.

—The Times of India: “Mars Could be Warm Enough for Humans in 15 Years; A Discovery that Changes Everything“

Mars has been viewed as a multi-millennial effort to terraform since the inception of the term, but there is new evidence that the time frame has changed dramatically. A published study in Science Advances gives new hope to those wishing to terraform Mars through nanoscopic engineered aerosol-like dust particles made from iron and aluminium found abundantly in the soils of Mars. Specifically, scientists feel that if we inject these engineered aerogels into the atmosphere, the resulting greenhouse effect will raise Mars’ surface temperature by over 50 degrees Fahrenheit in only 15 years.

—Ars Technica: “A Mission NASA Might Kill is Still Returning Fascinating Science from Jupiter“

Jupiter’s colossal storms generate lightning flashes at least 100 times more powerful than those on Earth, according to scientists analyzing data from NASA’s Juno spacecraft. The findings were published March 20 in the journal AGU Advances. Researchers used data recorded by Juno in 2021 and 2022, after NASA granted an extension to the spacecraft’s operations upon completing a five-year science campaign at Jupiter. Juno remains in good health, but NASA officials have not said if they will approve another extension for the mission. The issue is money.

—Astronomy.com: “NASA’s Van Allen Probe A Burns Up Over the Pacific after 14 Years in Space“

NASA’s Van Allen Probe A re-entered Earth’s atmosphere on Wednesday, March 11, at 6:37 a.m. EDT, marking the final chapter for a spacecraft that reshaped scientists’ understanding of the radiation environment around our planet. The U.S. Space Force confirmed the spacecraft came down over the eastern Pacific Ocean. NASA said most of the 1,300-pound (600 kilograms) probe burned up during reentry, though some pieces may have reached the surface. Its twin, Probe B, remains in orbit and is not expected to re-enter before 2030. The twin probes launched together on Aug. 30, 2012, on what was supposed to be a two-year mission. They operated for nearly seven years instead, circling Earth inside the Van Allen radiation belts — zones of high-energy charged particles held in place by the planet’s magnetic field. 

—Carnegie Science: ““Extragalactic Archeology” Reveals Nearby Galaxy’s Evolution“

A team of astronomers, including Carnegie Science’s Jeff Rich and other former Carnegie Observatories astronomers, have for the first time traced the history of a galaxy outside our own Milky way by studying chemical fingerprints in deep space, a new approach they are calling “extragalactic archeology.” Their findings are published in Nature Astronomy. “This is the first time that a chemical archaeology method has been used with such fine detail outside our own galaxy,” said lead author Lisa Kewley of the Center for Astrophysics | Harvard and Smithsonian.

—GeekWire: “Rubin Observatory Sends Out Thousands of Data Alerts with an Assist from Seattle Astronomers“

An astronomical alert system developed at the University of Washington started off with a bang this week, sending out 800,000 notifications about moving asteroids, exploding stars and other celestial changes detected by the Vera C. Rubin Observatory in Chile. Tuesday night’s surge was just the first wave of alerts. Eventually, the Alert Production Pipeline is expected to produce up to 7 million alerts per night. Astronomers around the globe will use the system to sift through the torrent of data, zeroing in on events ranging from newly detected asteroids to supernovas, variable stars and active galactic nuclei.

—Sky&Telescope: “Get Ready for the March 3, 2026, Predawn Total Lunar Eclipse“

On Tuesday, March 3rd, the full Moon glides through the darkest portion of Earth’s shadow, called the umbra, to create a dramatic total lunar eclipse. In the Western Hemisphere, the event occurs in the hours before dawn, while across Asia it happens during the evening. During the eclipse, Earth’s shadow is seen gradually edging across the face of the full Moon until the entire lunar disk glows deep orange or red. Then the sequence of events unfolds in reverse order, until the shadow leaves the lunar disk completely and the Moon returns to full brilliance.

—Futurism: “Astronomer Who Discovered Water on Distant Planet Murdered Outside Home“

A renowned Caltech astronomer who studied distant exoplanets was shot and killed outside his home in a rural area near Los Angeles, the LA Times reported…Among his most notable contributions to the field was leading research published in 2007 that, for the first time, captured enough light from distant exoplanets to identify the molecules in their atmospheres…and soon made the “monumental” discovery of detecting signs of water on another planet.
