‘Interstellar Glaciers’: NASA’s SPHEREx Maps Vast Galactic Ice Regions

NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than 600 light-years across, the ice was found inside giant molecular clouds — vast regions of gas and dust where dense clumps of […]

Starstruck

The Artemis II crew captured this photo of our galaxy, the Milky Way, on April 7, 2026. The Milky Way’s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Spanning more than 100,000 light-years, Earth is located along one of the galaxy’s spiral arms, about […]

Core Survey by NASA’s Roman Mission Will Unveil Universe’s Dark Side

The broadest planned survey by NASA’s upcoming Nancy Grace Roman Space Telescope will reveal hundreds of millions of galaxies scattered across the cosmos. After Roman launches as soon as this fall, scientists will use these sparkly beacons to study the universe’s shadowy underpinnings: dark matter and dark energy. “We set out to build the ultimate […]

Journey to Center of Milky Way With Upcoming NASA Roman Core Survey

At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA’s Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, planets, and unique objects that resist definition. Based on the input of astronomers from across the […]

NASA’s Fermi Spots Young Star Cluster Blowing Gamma-Ray Bubbles

For the first time, astronomers using NASA’s Fermi Gamma-ray Space Telescope have traced a budding outflow of gas from a cluster of young stars in our galaxy — insights that help us understand how the universe has evolved as NASA explores the secrets of the cosmos for the benefit of all. The cluster, called Westerlund […]

NASA Announces Plan to Map Milky Way With Roman Space Telescope

NASA’s Nancy Grace Roman Space Telescope team has released detailed plans for a major survey that will reveal our home galaxy, the Milky Way, in unprecedented detail. In one month of observations spread across two years, the survey will unveil tens of billions of stars and explore previously uncharted structures. “The Galactic Plane Survey will […]

NASA’s Roman Could Bring New Waves of Information on Galaxy’s Stars

Lee esta nota de prensa en español aqui. A team of researchers has confirmed stars ring loud and clear in a “key” that will harmonize well with the science goals and capabilities of NASA’s upcoming Nancy Grace Roman Space Telescope. Stars’ turbulent natures produce waves that cause fluctuations in their overall brightness. By studying these […]

NASA’s Webb Explores Largest Star-Forming Cloud in Milky Way

NASA’s James Webb Space Telescope has revealed a colorful array of massive stars and glowing cosmic dust in the Sagittarius B2 molecular cloud, the most massive and active star-forming region in our Milky Way galaxy.  “Webb’s powerful infrared instruments provide detail we’ve never been able to see before, which will help us to understand some […]

Milky Way Views

The Milky Way appears above Earth’s bright atmospheric glow in this Aug. 23, 2025, photograph from the International Space Station as it soared 261 miles above southern Iran at approximately 12:54 a.m. local time. The camera was configured for low light and long duration settings. Our home galaxy has hundreds of billions of stars, enough […]
