“I didn’t sign up to try to measure a new record or anything”, said Matt Carnicle, a volunteer for the NASA-sponsored Community Collaborative Rain, Hail, and Snow Network, or CoCoRaHS, project. Carnicle measured a whopping 29.06 inches of rainfall on June 18th, 2026, breaking an all-time 24-hour record for the state of Louisiana of 22.00 inches. “I’m just a regular guy who likes to track the weather, and I report what I get in my gauge whether it’s zero, two hundredths, or whatever is in there when I read it.”
CoCoRaHS (pronounced KO-ko-rozz) is a network of volunteer weather observers of all ages working together to measure and map rain, hail, and snow by measuring precipitation in their backyards. Together, these thousands of daily precipitation reports – openly available on the project website – are used by scientists and citizens for a wide variety of purposes, to include improving weather forecasting, informing water and land management, driving atmospheric models, and triggering flash flood and severe weather warnings.
Matt joined through a storm-spotter class where he learned how CoCoRaHS is part of a NASA hail research project focused on Gulf States in the Southeast United States. CoCoRaHS reports (and photos) of hail are used for researching the “melt rate” between when the satellite estimates the stone sizes in the clouds and what volunteers measure on the ground. Matt took it a step further and purchased a standardized rain gauge in order to participate with CoCoRaHS by measuring rainfall.
Matt’s June 18, 2026 rain measurement shatters Louisiana’s 1962 state record of 22.00 inches of rain in 24-hours (Hawaii holds the national record with 49.69 inches in 24-hours). Even more remarkably, the 29.06 inches he measured fell in less than 12 hours! According to Louisiana State Climatologist Jay Grymes, who validated Matt’s measurement along with National Weather Service representatives, an event of this magnitude in this area is expected to happen less than once in a thousand years. A National Oceanic and Atmospheric Administration (NOAA) committee will convene in the coming months to verify and document the new record.
You can join Matt and other CoCoRaHS volunteers and submit official rainfall reports to the National Weather Service. They’re also on the lookout for hail in the southeast, where CoCoRaHS and NASA are doing research on how hail melts as it moves from the clouds to the ground. The only requirement for participation is that volunteers use the correct manual gauge, which is precise to the nearest 1/100th of an inch and is approved by the National Weather Service (measurements from automated rain gauges are not accepted). Sign up here, and you might measure the next record precipitation event: https://science.nasa.gov/citizen-science/community-collaborative-rain-hail-and-snow-network/

Astronomers using NASA’s James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in our Milky Way galaxy.
The young, nearby star Beta Pictoris was already known to host two giant planets: Beta Pictoris b, one of the first exoplanets ever directly imaged, and Beta Pictoris c. The newly identified Beta Pictoris d makes it only the second planetary system known to contain at least three imaged planets. Unlike Beta Pictoris b and c, however, Beta Pictoris d was discovered not by identifying a bright point of light, but by detecting the unique chemical fingerprint of its atmosphere, a technique that could transform the search for worlds around other stars.
“This discovery adds another piece to an already fascinating planetary system,” said Aidan Gibbs, lead author of a new study published Wednesday in the Astrophysical Journal Letters and a postdoctoral researcher at the University of California, San Diego. “Beta Pictoris has long served as a laboratory for understanding how planetary systems form and evolve, and now we have another planet helping us tell that story.”
Located 63 light-years from Earth and about 23 million years old, Beta Pictoris is a nearby system in the Milky Way offering a rare glimpse of the interactions between newborn planets and the disk of dust and debris left behind from their formation.
The team estimates that the newfound Beta Pictoris d is likely at least two times the mass of Jupiter, making it the smallest of the three known giant planets in the system. Modeling suggests it likely circles around its star at about 30 astronomical units, comparable to the region occupied by Neptune in our own solar system. It’s the widest orbit of the known three planets, but still located inside the inner edge of the debris disk.
Although astronomers were not searching for another planet with Webb, Beta Pictoris d emerged while the team was using the telescope’s NIRSpec (Near-Infrared Spectrograph) to study the atmosphere of Beta Pictoris b. Specifically, they used NIRSpec’s Integral Field Unit, which obtains both an image and a spectrum from each pixel in an image.
“We weren’t looking for a new planet,” said Gibbs. “We were trying to understand one we already knew existed. Then, this telltale signal appeared in the data where we didn’t expect it.”
This signal was a series of peaks and troughs within the spectroscopic data where the team expected to see a smooth spectrum from light bouncing off dust. It was a distinctive pattern of carbon monoxide absorption lines, spread out like a barcode, an expected feature in giant planet atmospheres.
Because spectroscopy not only reveals chemical composition, but the motion of an object, the team was able to also extract radial velocity from the data. The team determined the planet’s speed, position, and alignment with the debris disk were all consistent with something orbiting Beta Pictoris rather than a background star or brown dwarf with carbon monoxide in its atmosphere.
“There was an unexpected bright source of light within the Integral Field Unit imaging, but we’ve learned not to trust bright blobs in images,” said Jean-Baptiste Ruffio, a research scientist at University of California, San Diego and principal investigator of the first Webb observations where the discovery was made. “They can be instrumental artifacts or other structures in the debris disk. By obtaining a spectrum at the same time as the image, we were able to quickly confirm our suspicions.”
Follow-up observations with Webb’s MIRI (Mid-Infrared Instrument) through a Director’s Discretionary Time request detected water vapor and methane, further confirming the planet’s identity while providing a richer look at the atmosphere of the planet.
Unlike traditional imaging, the spectroscopic approach allowed researchers to identify the planet and begin studying its atmosphere from the very first observation.
“A spectrum contains an incredible amount of information,” Ruffio said. “You don’t just learn that something is a planet; you immediately begin learning about its temperature, chemistry, and motion.”
A separate imaging study led by Ben Sutlieff of the University of Edinburgh and Markus Bonse of the European Southern Observatory complements the team’s findings with data from the European Southern Observatory’s Very Large Telescope and Webb’s NIRCam (Near-Infrared Camera) and independently confirmed the existence of Beta Pictoris d.


Beta Pictoris d remained hidden for years because it lies within one of the brightest debris disks known.
The dusty disk acts like fog, scattering light from the star, making it difficult for conventional imaging techniques to distinguish planets from surrounding structures. The team’s spectroscopic method with Webb effectively ignored that dust, isolating only the narrow molecular signatures unique to a planetary atmosphere.
Scientists say the planet’s presence may help explain why the famous debris disk has such a sharply defined inner edge and other puzzling structures. In fact, astronomers had already predicted the existence of a planet like Beta Pictoris d to account for the disk’s unusual structure.
Beyond expanding our understanding of Beta Pictoris, the discovery demonstrates a powerful new way to find exoplanets.
This is the first directly imaged planet discovered primarily through moderate-resolution spectroscopy, showing that astronomers can identify worlds in complex environments through their atmospheric fingerprints rather than relying solely on traditional coronagraphic imaging.
The researchers plan to continue analyzing Webb’s observations to better determine the planet’s temperature, atmospheric composition, and orbit, providing an even more detailed view of one of astronomy’s most iconic planetary systems.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Curiosity had a successful long weekend and came into this week ready to explore some more. We’ve been moving fairly rapidly through different mapped “units,” or distinct geological areas of interest, visiting a different one at each of our three stops this week. The terrain all around us can give us clues about the past environment of Gale Crater, and geologists can look at the different compositions and appearances of what may look like ordinary rocks to the rest of us, to infer how it was laid down and altered by its environment in the distant past.
All three of our stops this week included contact science with MAHLI and APXS, as well as compositional analyses with the ChemCam LIBS instrument. Mastcam and ChemCam also continued to study the broader context of this area with medium and longer-distance imaging of the buttes and other formations we see around us. Among the different layers and textures of bedrock are features that formed from some past erosion and we looked at different examples of these through the week, as well.
While every rock Curiosity chooses to examine is special (that’s why we give them all names!), two in particular stood out this week. Monday’s and Wednesday’s workspaces both contained rocks that were darker than the ones around them, so they may have been brought in from elsewhere, or could even be meteorites. To help figure out their histories, we turned LIBS on them to look at their compositions.
Of course we are not only interested in peering into Mars’ past — we also care about its present environment. As we approach the end of the Mars year, moving through summer in Gale Crater and looking towards autumn, the atmosphere almost seems to calm. The turn of the Mars year sees us transition from the dusty season back into the cloudy season, so we’re keeping a keen eye on both dust and clouds. This time of year is the last gasp of the dusty season, what we call the “C” storm season, when mid-size, regional dust storms can form. So we’re keeping an eye out for signs of these with both Mastcam and Navcam. Aside from our dust and cloud imaging, we — as always — have our trusty suite of REMS instruments adding to our daily meteorological record of Gale Crater with regular measurements.

It’s still relatively early in the summer season in the Northern Hemisphere, but several parts of North America were sweltering in mid-July.
The latest purveyor of heat was a strong ridge of high pressure that lingered in the upper atmosphere over the northern Rockies on the weekend of July 11-12, 2026. This pushed hot air toward the surface and trapped it there—a weather phenomenon meteorologists call a heat dome.
Heat domes put the brakes on convection and suppress clouds and precipitation. This allows sunlight to reach Earth’s surface relatively unhindered and further elevate air temperatures. As a result of the July heat dome, sites in Montana, Wyoming, and Utah broke all-time temperature records.
The map above shows air temperatures across the United States on July 12, 2026, at 2 p.m. Mountain Time, modeled at 2 meters (6.5 feet) above the ground. It was produced by combining satellite observations with temperatures predicted by a version of the GEOS (Goddard Earth Observing System) model, which uses mathematical equations to represent physical processes in the atmosphere. The darkest reds indicate areas where temperatures approached or exceeded 45 degrees Celsius (113 degrees Fahrenheit).
A preliminary analysis from the National Weather Service office in Billings found that temperature sensors at airports in Billings and Miles City, Montana (111°F and 115°F, respectively), and Sheridan, Wyoming (109°F), all recorded new all-time record highs on July 12. Each of these stations topped its previous record by at least 2°F, with Miles City breaking its record by a full 4°F. The Montana records date to the 1930s; the Sheridan record begins in 1907.
Multiple locations in Utah broke all-time records as well, according to the National Weather Service office in Salt Lake City, including Deseret (111°F), Salt Lake City (109°F, or 4°F above the previous record), and Randolph (100°F, or 6°F above the previous record). These stations in Utah have records that date back to the 1890s.
Extreme heat doesn’t just make people uncomfortable. It can have serious health consequences, particularly for older people. Extreme heat worsens common age-related health conditions such as heart, lung, and kidney disease. Health tracking data from the U.S. Centers for Disease Control and Prevention shows that the rate of heat-related emergency department visits in the Mountain states spiked tenfold during the July heat.
Heat waves like this one have become more frequent in the United States in recent decades, according to researchers at NASA’s Goddard Space Flight Center. Using a NASA modeling system called MERRA-2 (Modern-Era Retrospective analysis for Research and Applications-2), one NASA team found that summer heat waves in the U.S. roughly doubled in number between 1980 and 2023, increasing from an average of two to four per month.
Forecasters expect the heat dome to spread east into the Midwest, New England, and the Mid-Atlantic in the coming days, where triple-digit temperatures are likely in some areas. The United States isn’t alone in facing significant heat. Parts of both Western Europe, Central Asia, and East Asia are also facing heat waves.
