This NASA/ESA Hubble Space Telescope image features the remote galaxy HerS 020941.1+001557, which appears as a red arc that partially encircles a foreground elliptical galaxy.ESA/Hubble & NASA, H. Nayyeri, L. Marchetti, J. Lowenthal This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the galaxy was 5.5 billion light-years away and began its trek to us through expanding space). Known as HerS 020941.1+001557, this remote galaxy appears as a red arc partially encircling a foreground elliptical galaxy located some 2.7 billion light-…

X-ray: NASA/CXC/ICRAR, Curtin Univ./Z. Wang et al.; Infrared: NASA/JPL/CalTech/IPAC; Radio: SARAO/MeerKAT; Image processing: NASA/CXC/SAO/N. Wolk Scientists have discovered a star behaving like no other seen before, giving fresh clues about the origin of a new class of mysterious objects. As described in our press release, a team of astronomers combined data from NASA’s Chandra X-ray Observatory and the SKA [Square Kilometer Array] Pathfinder (ASKAP) radio telescope on Wajarri Country in Australia to study the antics of the discovered object, known as ASKAP J1832−0911 (ASKAP J1832 for short). ASKAP J1832 belongs to a class of objects called “long period radio tr…

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) How do we do research in zero gravity? Actually when astronauts do experiments on the International Space Station, for instance, to environment on organisms, that environment is actually technically called microgravity. That is, things feel weightless, but we’re still under the influence of Earth’s gravity. Now, the very microgravity that we’re trying to study up there can make experiments actually really kind of difficult for a bunch of different reasons. First of all, stuff floats. So losing things in the ISS is a very real possibility. For example, the…

5 Min Read Career Spotlight: Mathematician (Ages 14-18) What does a mathematician do? Mathematicians use their expert knowledge of math to solve problems and gain new understanding about how our world works. They analyze data and create mathematical models to predict results based on changes in variables. Many different fields rely heavily on math, such as engineering, finance, and the sciences. Using math to solve real-world problems is called “applied math.” This is different from “abstract math,” which refers to the study of the structure of mathematics. At NASA, applied m…

What do music ensembles and human spaceflight have in common? They require the harmonization of different elements to create an inspiring opus. NASA’s Paige Whittington has experience with both. As a principal flutist for Purdue University’s Wind Ensemble, Whittington helped fellow flutists play beautiful music together while pursuing her graduate degree. Now, as a space exploration simulation architect at Johnson Space Center in Houston, she strives for a cross-team harmony that can inform the agency’s Moon to Mars exploration approach. “Simulation often sits at the intersection of several teams because we integrate various designs and mission …

NASA/Michael DeMocker Just after sunrise, the waning gibbous moon sets just behind a waving United States flag on March 19, 2025, in this image from NASA’s Michoud Assembly Facility in New Orleans. The waning gibbous moon phase comes after the full moon. As the Moon begins its journey back toward the Sun, the opposite side of the Moon now reflects the Moon’s light. The lighted side appears to shrink, but the Moon’s orbit is simply carrying it out of view from our perspective. The Moon also rises later and later each night.
