The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way. The galaxy […]

NICER Status Updates
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 […]
Frigid Exoplanet in Strange Orbit Imaged by NASA’s Webb
A planetary system described as abnormal, chaotic, and strange by researchers has come into clearer view with NASA’s James Webb Space Telescope. Using Webb’s NIRCam (Near-Infrared Camera), researchers have successfully imaged one of two known planets surrounding the star 14 Herculis, located 60 light-years away from Earth in our own Milky Way galaxy. The exoplanet, […]
NASA’s Chandra Sees Surprisingly Strong Black Hole Jet at Cosmic “Noon”
A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA’s Chandra X-ray Observatory and discussed in our latest press release. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the big bang itself. Astronomers used […]
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 […]
NASA’s IXPE Obtains First X-ray Polarization Measurement of Magnetar Outburst
What happens when the universe’s most magnetic object shines with the power of 1000 Suns in a matter of seconds? Thanks to NASA’s IXPE (Imaging X-ray Polarimetry Explorer), a mission in collaboration with ASI (Italian Space Agency), scientists are one step closer to understanding this extreme event. Magnetars are a type of young neutron star […]
