Tessera AI model offers accessible way to view Earth

Tessera AI model offers accessible way to view Earth Lisa Lock Scientific Editor Andrew Zinin Lead Editor A foundation model trained on Earth observation data from Copernicus Sentinel-1 and Sentinel-2 has been made widely available to researchers, it was announced at a computer industry conference this week in Denver, U.S. Tessera, an advanced artificial intelligence (AI) model, offers high-accuracy datasets that encode what the satellite "sees" of Earth's surface during the course of a...

ESA selects two new scout-class missions

ESA selects two new scout-class missions Lisa Lock Scientific Editor Andrew Zinin Lead Editor When it comes to understanding Earth and our changing environment, space is the place. Not only does it give us an overall holistic view of the planet below, but satellite-based imagery can transcend national boundaries and give us an understanding of key changes that often go unseen at ground level. Now, the European Space Agency (ESA) has chosen two new missions to address key questions in Earth...

A faster way to forecast alien weather

A faster way to forecast alien weather Lisa Lock Scientific Editor Andrew Zinin Lead Editor The TRAPPIST-1 system, located about 41 light years from Earth, has been a focal point of much exoplanetary discussion—mainly because it has seven confirmed planets orbiting a dim M-dwarf star. Two of those planets—TRAPPIST-1e and -1f—are thought to be in the star's habitable zone. However, the habitable zone of M-dwarfs is so close to the star itself, the planets are likely tidally locked to it,...

Space station dust maps slash climate uncertainty over iron-rich particles

Space station dust maps slash climate uncertainty over iron-rich particles Lisa Lock Scientific Editor Robert Egan Associate Editor New research from a team of scientists led by Cornell is transforming how researchers understand one of the atmosphere's most abundant and least understood constituents: mineral dust. Mineral dust, composed of tiny particles lifted from arid regions including the Sahara, Middle East and East Asia, plays a complex role in Earth's climate system. These particles...

Ever seen a cave cricket? Australia now has three new species of these spindly, spider-like creatures

Ever seen a cave cricket? Australia now has three new species of these spindly, spider-like creatures Lisa Lock Scientific Editor Robert Egan Associate Editor When you picture a cave, you probably think of an environment devoid of life. But for most caves on Earth, this couldn't be further from the truth.

Silent volcanic gas buildup revealed six months before La Palma eruption

Silent volcanic gas buildup revealed six months before La Palma eruption Lisa Lock Scientific Editor Robert Egan Associate Editor Researchers at Geosciences Barcelona (GEO3BCN-CSIC) have developed a novel way to monitor the silent accumulation of volcanic gases beneath Earth's surface using seismic ambient noise. The results could significantly improve early warning systems for volcanic eruptions. The continuous but invisible release of gases from underground is notoriously difficult to...

'Out-of-place' rocks reveal how a young ocean formed

'Out-of-place' rocks reveal how a young ocean formed Lisa Lock Scientific Editor Robert Egan Associate Editor Deep below the Tyrrhenian Sea offshore Italy, scientists drilled into what they thought would be dark mantle rock—and found pieces of granite that seemingly had no business being there. Those unexpected intrusions turned out to offer a rare glimpse of how a massive fault rapidly pulled deep Earth rocks toward the surface during the opening of a young ocean basin. "When we first...

Kamo'oalewa asteroid's lunar origin challenged ahead of Tianwen-2 arrival

June 2, 2026 report Kamo'oalewa asteroid's lunar origin challenged ahead of Tianwen-2 arrival Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor China's Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo'oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had assumed originated from the moon. However, a new study published in Nature Communications suggests...

Expedition to Antarctica advances research on potential melanoma treatment

Expedition to Antarctica advances research on potential melanoma treatment Lisa Lock Scientific Editor Andrew Zinin Lead Editor Deep beneath the icy waters surrounding Antarctica, a small marine organism may hold clues to a future cancer treatment. Researchers from USF recently returned from a six-week expedition in one of the most remote environments on Earth to study a species of ascidian, or sea squirt, that contains a bacterium capable of killing melanoma cancer cells. The discovery was...
