August 5, 2025 Science Observations Remain Paused for NASA’s NICER Telescope Science operations by NASA’s NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, remain paused as the team continues to evaluate the telescope’s systems after an issue developed with one of its motors. The motor is unable to move […]

Hubble Studies Small but Mighty Galaxy
This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is situated just 12.5 million light-years away in the constellation Canes Venatici (the Hunting Dogs). It is a member of the M94 galaxy group, which is near the Local Group of galaxies that the Milky Way […]
Hubble Studies a Spiral’s Supernova Scene
This serene spiral galaxy hides a cataclysmic past. The galaxy IC 758, shown in this NASA/ESA Hubble Space Telescope image, is situated 60 million light-years away in the constellation Ursa Major. Hubble captured this image in 2023. IC 758 appears peaceful, with its soft blue spiral arms curving gently around its hazy barred center. However, […]
NASA’s Roman to Peer Into Cosmic ‘Lenses’ to Better Define Dark Matter
A funky effect Einstein predicted, known as gravitational lensing — when a foreground galaxy magnifies more distant galaxies behind it — will soon become common when NASA’s Nancy Grace Roman Space Telescope begins science operations in 2027 and produces vast surveys of the cosmos. A particular subset of gravitational lenses, known as strong lenses, is […]
NASA’s Webb ‘UNCOVERs’ Galaxy Population Driving Cosmic Renovation
Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today. “When it comes to producing ultraviolet light, these small galaxies punch well above their weight,” said Isak Wold, an assistant […]
Webb Sees Sombrero Galaxy in Near-Infrared
After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared. In the newest image, released on June 3, 2025, the Sombrero galaxy’s tightly packed group of stars at the galaxy’s center is illuminated while the dust in […]
Hubble Captures Starry Spectacle
A galaxy ablaze with young stars is the subject of this NASA/ESA Hubble Space Telescope image. Named NGC 685, this galaxy is situated about 64 million light-years away in the constellation Eridanus (the River). NGC 685 is a barred spiral because its feathery spiral arms sprout from the ends of a bar of stars at […]
Hubble Captures Cotton Candy Clouds
This NASA/ESA Hubble Space Telescope image features a sparkling cloudscape from one of the Milky Way’s galactic neighbors, a dwarf galaxy called the Large Magellanic Cloud. Located 160,000 light-years away in the constellations Dorado and Mensa, the Large Magellanic Cloud is the largest of the Milky Way’s many small satellite galaxies. This view of dusty gas clouds […]
Galaxy Clusters on Course to Crash Again, NASA’s Chandra Finds
New observations from NASA’s Chandra X-ray Observatory and other telescopes have captured a rare cosmic event: two galaxy clusters have collided and are now poised to head back for another swipe at each other. Galaxy clusters are some of the largest structures in the Universe. Held together by gravity, they are monster-sized collections of hundreds […]
NASA’s Webb Rounds Out Picture of Sombrero Galaxy’s Disk
After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared. In the newest image, the Sombrero galaxy’s huge bulge, the tightly packed group of stars at the galaxy’s center, is illuminated, while the dust in […]
