NASA officials said the icy visitor was first spotted in March 2022 while it was inside the orbit of Jupiter. The icy celestial body - called C/2022 E3 (ZTF), is making its closest approach to Earth on 2 February.
Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times.
Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. They could be used to send spacecraft to the far reaches of our planetary system.
Comet 67P/Churyumov-Gerasimenko has its own far-ultraviolet aurora, data reveal. It is the first time such electromagnetic emissions in the far-ultraviolet have been documented on an object other than a planet or moon.
At least 7.5 times as long as the distance between the Earth and the Sun (over a billion km), Comet 153P/Ikeya-Zhang’s ion tail is nearly double the length of the previous record-holder, Comet Hyakutake.
The Hubble Space Telescope has captured two images showing Atlas, originally up to 180 metres across, has broken into as many as 30 pieces, each about the size of a house.
Comet 2I/Borisov is only the second interstellar object known to have passed through the solar system. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star.
It is now confirmed that the comet spotted a few weeks ago by amateur astronomer Gennady Borisov from MARGO Observatory, Crimea, is indeed coming from interstellar space. This is only the second known interstellar object to pass through our Solar System.
According to the latest findings, it seems that ‘Oumuamua may actually be more icy than previously thought (thus indicated that it is a comet) and is not an alien spacecraft as some had hoped.
Astronomers have observed an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features.
Ingredients crucial for the origin of life on Earth, including the simple amino acid glycine and phosphorus, key components of DNA and cell membranes, have been discovered at Comet 67P/Churyumov-Gerasimenko.
