Ozone high in the stratosphere protects us from the Sun’s ultraviolet light. But ozone near the ground is a pollutant that harms people and plants. The San Joaquin Valley has some of the most polluted air in the country, and NASA scientists with the new Ozone Where We Live (OWWL) project are working to measure ozone and other pollutants there. They need your help!  

Do you live or work in Bakersfield, CA? Sign up to host an ozone sensor! It’s like a big lunch box that you place in your yard, but it’s not packed with tuna and crackers. It’s filled with sensors that measure temperature and humidity and sniff out dangerous gases like methane, carbon monoxide, carbon dioxide, and of course, ozone. 

Can you fly a plane? Going to the San Joaquin Valley? Sign up to take an ozone sensor on your next flight! You can help measure ozone levels in layers of the atmosphere that are hard for satellites to investigate. Scientists will combine the data you take with data from NASA’s TEMPO satellite to improve air quality models and measurements within the region.

Iceland is one of the most active volcanic regions in the world, but its seismic nature is part of a much broader geological history.

In a groundbreaking discovery, scientists, supported by an ESA-funded project, have uncovered the underlying forces that forged the North Atlantic’s fiery volcanic past – shedding light on the vast geological region that spans from Greenland to western Europe, which is home to iconic natural wonders like the Giant’s Causeway in Northern Ireland. 

A radio signal from the dawn of time could help scientists weigh the first stars and reveal how they lifted the cosmic darkness.

Our climate seems to be more sensitive to greenhouse gas emissions than some researchers had hoped, meaning the world will have to up its decarbonisation efforts

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead formed inside a colossal black hole.

NASA has announced a new launch date for the private Axiom astronaut launch to the ISS, following delays due to leaks aboard the space station.

Stephen Hawking has made a compelling case that black holes eventually evaporate, but the time scales are beyond our ability to detect it. A new paper suggests that primordial black holes passing through the Solar System could be releasing positron emissions that would be detectable when they pass up to 10 AU from Earth. If found, they would confirm Hawking's theories and provide an explanation for dark matter. Unfortunately, our best technology isn't quite sensitive enough.

The Chinese Space Agency took a major step toward its 2030 lunar mission goals this week by successfully testing the escape system of its next-generation Mengzhou spacecraft. At the Jiuquan Satellite Launch Center, engineers conducted their first zero-altitude escape flight test at 12:30 PM when solid rocket engines ignited, propelling the spacecraft skyward for 20 seconds before the return capsule separated, deployed parachutes, and landed safely.

As different nations begin conducing operations on the lunar surface, humanity's penchant for geopolitical struggles will likely be along for the ride. Tension between nations and/or corporations could grow. There are few rules and treaties that can calm this potential rising tension. What kinds of conflict might erupt and how can it be prevented?

Star formation peaked during the Cosmic Noon, which spanned from 10 to 12 billion years ago. During Cosmic Noon, star formation was 10 to 100 times greater than it is now. New research shows that a particular class of galaxy was experiencing its first intense burst of star formation during this time. Were these galaxies the progenitors of galaxies like the Milky Way?

Modern telescopes like the Zwicky Transient Facility (ZTF) are watching the sky for any changes, and can report a million variations in a single night. This will multiply when Vera Rubin comes online. SETI researchers are looking for specific events that could be caused by an intelligent civilization, and have developed methods to search through astronomical alerts automatically. This could give SETI researchers dozens of potential targets a night to follow up on, scanning for signals or anomalous changes in brightness.

You're probably aware that most of the matter of the Universe is "dark matter," and astronomers still don't know what it is. But 75% of the regular matter in the Universe is also hidden, located in the thin gas between galaxies. Probing this gas is difficult, but astronomers have used a new technique, analyzing the light from fast radio bursts as they pass through billions of light-years of gas. Longer, redder wavelengths are slowed down compared to shorter, bluer wavelengths, allowing the hidden material to be weighed.
