9 Min Read Temperatures Across Our Solar System An illustration of our solar system. Planets and other objects are not to scale. Credits: NASA What’s the weather like out there? We mean waaaay out there in our solar system – where the forecast might not be quite what you think. Let’s look at the mean temperature of the Sun, and the planets in our solar system. The mean temperature is the average temperature over the surface of the rocky planets: Mercury, Venus, Earth, and Mars. Dwarf planet Pluto also has a solid surface. But since the gas giants don’t have a surface, the mean is the average temperature at what would b…

3 min read NASA’s Hubble Measures the Size of the Nearest Transiting Earth-Sized Planet This is an artist’s concept of the nearby exoplanet LTT 1445Ac, which is the size of Earth. The planet orbits a red dwarf star. The star is in a triple system, with two closely orbiting red dwarfs seen at upper right. The black dot in front of the bright light-red sphere at image center is planet LTT 1445Ac transiting the face of the star. The planet has a surface temperature of roughly 500 degrees Fahrenheit. In the foreground at lower left is another planet in the system, LTT 1445Ab. The view is from 22 light-years away, looking back toward our Sun, which is the bright dot at…

Goddard’s Office of the Chief Technologist named engineer Steven Denis as the FY23 Internal Research and Development (IRAD) Innovator of the Year, an honor the office bestows annually on individuals who demonstrate the best in innovation. Kevin DenisCredit: NASA / Christopher Gunn Denis demonstrated persistence and innovation in developing hair-thin photon sieves to focus extreme ultraviolet light – a difficult wavelength to capture. Thin membranes matter for solar science, he said, because these sieves transmit up to seven times more light than thicker materials. Denis’s work will open new ways to study the Sun in better detail and understand its influence on Earth …

4 min read NASA Telescope Data Becomes Music You Can Play For millennia, musicians have looked to the heavens for inspiration. Now a new collaboration is enabling actual data from NASA telescopes to be used as the basis for original music that can be played by humans. Since 2020, the “sonification” project at NASA’s Chandra X-ray Center has translated the digital data taken by telescopes into notes and sounds. This process allows the listener to experience the data through the sense of hearing instead of seeing it as images, a more common way to present astronomical data. A musical ensemble performs soundscape that composer Sophie Katsner created …

Our world is facing many urgent challenges, such as climate change, water insecurity, and food insecurity. Maintaining and improving quality of life around the world requires bringing together innovators across disciplines and countries to find creative solutions. One critical tool for understanding and improving the urgent challenges facing our world is Earth observation data, meaning data that is gathered in outer space about life here on Earth! Earth observation data provides accurate and publicly accessible information on our atmosphere, oceans, ecosystems, land cover, and built environment. The United States and its partners have a long history of exploring outer…

NASA / William R. Pogue Astronaut William R. Pogue, Skylab 4 pilot, recorded this wide scene of his crewmates, astronauts Edward G. Gibson (left), science pilot, and Jerry P. Carr (right), commander, on the other end of the orbital workshop on Feb. 1, 1974. Also in the frame are parts of three spacesuits, used on several EVA sessions during the third and final mission on the Skylab space station. Skylab 4 launched on Nov. 16, 1973. Pogue, Gibson, and Carr were the first all-rookie crew since Gemini 8 in 1966. The crew continued the science program begun by the previous two Skylab crews, including biomedical investigations on the effects of long-duration space flight…

8 Min Read Satellite Data Can Help Limit the Dangers of Windblown Dust Dust storms present a growing threat to the health and safety of U.S. populations. A new model, powered by NASA and NOAA satellite data, provides important early warnings. Credits: Stock Footage Provided by Pond5/EnglerAerial Interstate 10, an artery that cuts through the rural drylands of southern New Mexico, is one of the country’s deadliest roadways. On one stretch of the highway, just north of a dry lakebed called Lordsburg Playa, fatal collisions occur with such regularity that officials often call it the “dust trap.” It’s a fitting name. Since 1…

6 min read NASA Data Reveals Possible Reason Some Exoplanets Are Shrinking This artist’s concept shows what the sub-Neptune exoplanet TOI-421 b might look like. In a new study, scientists have found new evidence suggesting how these types of planets can lose their atmospheres. NASA, ESA, CSA, and D. Player (STScI) A new study could explain the ‘missing’ exoplanets between super-Earths and sub-Neptunes. Some exoplanets seem to be losing their atmospheres and shrinking. In a new study using NASA’s retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside ou…

Scientists are following neon signs in a search for clues to one planetary system’s future and the past of another – our own solar system. Following up on a peculiar reading by NASA’s previous infrared flagship observatory, the now-retired Spitzer Space Telescope, the agency’s James Webb Space Telescope detected distinct traces of the element neon in the dusty disk surrounding the young Sun-like star SZ Chamaelontis (SZ Cha). Image: SZ Chamaeleontis Protoplanetary Disk (Artist Concept ) In this artist concept, the young star SZ Chamaeleontis (SZ Cha) is surrounded by a disk of dust and gas with the potential to form a planetary system. Once our solar system lo…

2 min read NASA’s X-59 Goes from Green to Red, White, and Blue Lockheed Martin NASA’s X-59 quiet supersonic aircraft continues to make progress, most recently moving to the paint barn at Lockheed Martin Skunk Works’ facility in Palmdale, California. The X-59’s paint scheme will include a mainly white body, a NASA “sonic blue” underside, and red accents on the wings. The paint doesn’t just add cosmetic value. It also serves a purpose – the paint helps to protect the aircraft from moisture and corrosion and includes key safety markings to assist with ground and flight operations. The aircraft made the move to the paint barn on Nov. 14, 2023. Once it …
