At up to 30 km wide, 3I/ATLAS is officially dummy thicc—with two Cs and a tail. Astronomers are calling it “the Lizzo of ...

Hopkins and Lintott are two of the six authors of a new paper that uses the new model to trace the origin of Comet 3I/ATLAS, and it appears to be coming from a completely different region of the ...

Astronomers have confirmed the discovery of a rare celestial visitor from beyond our Solar System. The comet was first spotted on 1 July 2025 by the Asteroid Terrestrial-impact Last Alert System ...

Astronomers have confirmed the presence of 3I/ATLAS, a rare interstellar comet originating from a distant star system, now traversing our solar system.

I/ATLAS, also known as C/2025 N1 (ATLAS), originated in a distant star system, far beyond the boundaries of our solar system.

The first so-called grand solar minimum of the six recognized within this time period is the Homeric Minimum, which lasted from about 800 BC until 600 BC. Others have lasted between 40 and 150 years.

Solar Orbiter unveils sun’s chaotic magnetic south pole in historic first Solar Orbiter reveals sun’s south pole and magnetic patchwork—offering clues to its 11-year polarity flip.

Stretching nearly a light-year from the Sun, the Oort Cloud serves as a cosmic reservoir of ancient material left over from the solar system’s formation over 4.5 billion years ago.

And Solar Orbiter, with its highly inclined orbit, is seeing more details of the Sun’s magnetic field than ever before. Right now, the Sun is at a special time in its 11-year cycle, having ...

One by one, they both hit the "wall of fire" at the boundaries of our home system, measuring temperatures of 30,000-50,000 kelvin (54,000-90,000 degrees Fahrenheit) on their passage through it.
