New Hubble observations of NGC 4698 in the Virgo Cluster show a spiral galaxy whose central stars and gas rotate perpendicular to its disk, likely the result of accreted outside gas and a past minor merger. The finding is a reminder that galaxies are not finished objects: they still grow by consuming their surroundings.
A verified preview of Monday's 3 p.m. EDT NASA and Boeing briefing on Starliner: what is confirmed, what happened on the 2024 Crew Flight Test, and why a second independent US crew vehicle matters for the space station and beyond.
A shoebox-sized NASA CubeSat built around a single non-toxic fuel tank feeding both a powerful chemical engine and gentle electrospray thrusters has cleared leak, thermal vacuum and spin tests at Marshall Space Flight Center, ahead of a launch scheduled no earlier than October 1, 2026.
The top $300,000 prize went to Chinyere Ukeje of Philadelphia for the Adaptive Nourishment Infrastructure (ANI), a modular ecosystem of agriculture, fermentation, fungi cultivation and closed-loop nutrient recycling designed to produce half a crew's food away from Earth. Here is why feeding a Mars crew is one of the harder engineering problems, and what the five winners actually delivered.
NASA and NSIDC report the 2026 Arctic minimum tied for 10th lowest, consistent with a decade-scale plateau. Here is what that means for readers, what it does not mean, and why the Antarctic side is harder to read.
The far-infrared telescope will survey the cold dust where planets, stars and water form, a band JWST and radio telescopes leave uncovered. Selection funds preliminary design; a confirmation review still stands between PRIMA and construction.
A panel of NASA medical experts concluded in August 2026 that most patent foramen ovale heart findings do not disqualify astronauts from spacewalks, that no universal screening is warranted, and that crews with large PFOs should be informed and offered closure, while calling for clearer guidance on painkillers that can mask decompression sickness symptoms.
A eukaryotic amoeba found in Lassen Volcanic National Park reproduces at 145 degrees Fahrenheit, breaking the previous 140-degree ceiling for complex life and widening the conditions under which NASA will search for life beyond Earth.
NASA used its planetary archive, lunar datasets and information standards as working examples for Artemis Accords partners. The sessions advanced technical coordination without creating a binding international system.
The final NextSTEP-3 solicitation targets power, oxygen extraction and manufacturing technologies that still require controlled testing before any lunar deployment can be considered.
NASA's newest flagship observatory has completed its first critical deployments and begun commissioning. Its real promise lies in wide-field infrared measurements, open data, and a survey scale that will demand new forms of scientific computing.
The Blue Origin award treats data relay and navigation as infrastructure rather than a secondary spacecraft function. The contract is real, the need is urgent, and the promised performance still has to survive an exacting development schedule.
