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.
Idea of microbes originating from space. Microbes can survive frozen, deep within the permafrost for millions and even billions of years. They might be perfectly adapted for a life on some frozen object, traveling through space.
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.
An international team studying 3200 Phaethon, a 3.6-mile-long rock believed responsible for the annual Geminid meteor shower, has revealed that the asteroid's surface exhibits a blue color.
Last October, researchers spotted a long, skinny object speeding through our solar system. Additional observations have now earned the object a comet label.
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.
