SUNSET: 
Asteroid Ryugu Also Contains Life’s Building Blocks
Samples returned from Ryugu contain all five nucleobases, just like from asteroid Bennu. The find suggests life’s ingredients could have come from outside Earth.
Asteroid Didymos's Heliocentric Orbit Altered by Impact on its Moon
Dozens on amateur astronomers helped measure the minuscule difference in Didymos’s trajectory around the Sun, after NASA’s DART mission impacted its moon.
Lunar Impact from Asteroid 2024 YR4 Ruled Out
The latest JWST images, along with archival images taken before the asteroid was even discovered, combine to refine its trajectory.
Updates on Interstellar Comet 3I/ATLAS: NASA Images, Many Tails, and Non-gravitational Forces
Now that Comet 3I/ATLAS has emerged from the Sun's glare, its behavior is being monitored by every available observatory.
Newly Discovered Asteroid Circles the Sun Inside Venus’s Orbit
Astronomers have discovered a second asteroid in the inner solar system, circling the Sun almost entirely within the orbit of Venus.
Mars Orbiters' Front-row Seats to the Interstellar Comet
Spacecraft orbiting the Red Planet will aim a suite of instruments at Comet 3I/ATLAS to capture details about this enigmatic object.
Best Evidence Yet for Past Life on Mars?
The Perseverance has found compounds associated with life on Earth. But whether they indicate life on Mars awaits sample return.
Meet 2025 PN7, Earth’s New Quasi-moon
Just discovered, it’s been orbiting the Sun alongside Earth for decades, and will continue to do so for decades more
Interstellar Comet 3I/ATLAS: What We Know Now
Observations have revealed the comet’s fuzzy coma, hinted at a weird tail, and suggested an ancient history. Plus, some missions might keep observing the interstellar comet when it ducks behind the Sun.
Another Dwarf Planet in Our Solar System?
A newly discovered object in the outer solar system, 2017 OF201, is the largest found in more than a decade.
Near-Earth Asteroid 2024 YR4 Might Aim for the Moon
The asteroid that will now definitely not hit Earth has the highest odds ever for a predicted lunar impact — but a miss is still more likely.
Webb Telescope Has Weighed in on Impact Odds for Asteroid 2024 YR4 (Updated)
So far, searches for archival images that could confirm or rule out the asteroid's impact have come up dry, but Webb observations in May could help pin down the orbit.
It’s Official: Saturn Has 128 New Moons
With a total now of 274 known moons, Saturn leads all of the planets by far.
Moon's Water Ice Might Be More Accessible Than We Thought
Results from India’s Chandrayaan 3 lander show below-freezing conditions exist farther from the poles than expected.
Asteroid Won't Hit Earth, But Might Hit Moon — a Potential Science Bonanza
2024 YR4 is no longer a danger for Earth, and a (small) chance of a lunar impact could provide great science data.
Newly Discovered Asteroid Has Slight Chance of Earth Impact in 2032
The discovery marks only the second time that an asteroid's impact risk has reached greater than a 1% chance.
Space Industry Adds Threats to Astronomy, Light Pollution Remains a Big Problem
Multiple effects from ever-increasing satellite launches could impact future observations; the biggest threat to astronomy, though, is still coming from the ground.
Webb Telescope Shows Unexpectedly Crowded Asteroid Belt
A new analysis of archival Webb telescope data reveals small asteroids in the main asteroid belt are far more numerous than thought.
Unveiled: The Youngest Transiting Exoplanet Ever Detected
A passing star may have warped a veil of dust to expose the embryonic planet.
Arecibo’s Powerful Radar May Have Contributed to the Telescope’s Demise
The Arecibo Observatory’s radar system may have produced currents that weakened the zinc sockets holding the cables in place, new report says.
