Researcher Noemí Pinilla-Alonso explained that the composition is uncharacteristic of objects near Neptune. Its gaseous and solid states, which lead to behavior like that of an asteroid and a comet, are also head-scratchers.

Comet ATLAS hit a maximum magnitude of -3.4 during its close encounter with the sun, just shy of the brightness of Venus in the night sky.

January 13, 2025, as Comet G3 ATLAS (C/2024) reaches its peak brightness. This once-in-a-lifetime spectacle marks the comet's closest approach to the Sun, bringing it within 8.7 million miles of the Sun at its perihelion.

A rare celestial event will take place tonight as Comet G3 ATLAS (C/2024) reaches its peak brightness tonight. The comet was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile, on April 5, 2024.

Comet G3 ATLAS is set to shine at its brightest this week, potentially outshining Venus and Jupiter. G3 ATLASs orbit is so big that it takes roughly 160,000 year to go around the Sun. As it approaches perihelion on January 13,

Scientists have made a shocking discovery about a rare object in our solar system likened to an asteroid-comet hybrid. Astronomers from the University of Central Florida have made the space discovery using the James Webb Space Telescope (JWST).

Comet G3 ATLAS (C/2024) is expected to reach its maximum brightness tomorrow. The celestial phenomenon may even outshine the planets Venus and Jupiter. The comet was first spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey in Chile on April 5, 2024. It was at magnitude +19 then and hard to spot due to its faintness.

A celestial body recently discovered by a Chinese observatory has been confirmed as a comet by the International Astronomical Union IAU Astronomers

Astronomer Dean Regas gives us the lowdown on the best things to look out for this winter, from a “planet parade” to the ATLAS comet.

NASA and famed astronaut Buzz Aldrin say stargazers have the best chance of catching a glimpse of Saturn and Venus in alignment starting Saturday. The planets have been shuffling toward each other in the sky and will appear closest this weekend, appearing only inches apart to the human eye.

Skies over South Carolina kick off 2025 with a planet parade, ancient comet and the muse of "Beyond Antares," a 23rd-century love song from "Star Trek" fame.

Venus, Mars, Jupiter and Saturn are visible to the naked eye this month and for part of February. Uranus and Neptune can be spotted with binoculars and telescopes.
