NASA’s James Webb Space Telescope recently zeroed in on the Bullet Cluster — delivering highly detailed images that show a greater abundance of extremely faint and distant galaxies than ever before. Using Webb’s crisp near-infrared observations of this region, researchers…
The light that the NASA/ESA Hubble Space Telescope collected to create this image reached the telescope after a journey of 250 million years. Its source was the spiral galaxy UGC 11397, which resides in the constellation Lyra (The Lyre). At first glance, UGC 11397…
When two stars orbit one another in such a way that one blocks the other’s light each time it swings around, that’s an eclipsing binary. A new paper from NASA’s Eclipsing Binary Patrol citizen science project presents more than 10,000…
Present-day disk galaxies often contain a thick, star-filled outer disk and an embedded thin disk of stars. For instance, our own Milky Way galaxy’s thick disk is approximately 3,000 light-years in height, and its thin disk is roughly 1,000 light-years…
Astronomers using NASA’s James Webb Space Telescope have captured compelling evidence of a planet with a mass similar to Saturn orbiting the young nearby star TWA 7. If confirmed, this would represent Webb’s first direct image discovery of a planet,…
June 24, 2025 NASA’s NICER Telescope Suspends Science Operations NASA’s NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, has paused observations due to a problem with one of the motors that drives its ability…
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…
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…
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…
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…
