A gigantic comet was originally mistaken for a dwarf planet

Astronomers believe they may have discovered the largest comet in history. The massive comet is called Bernardinelli-Bernstein after its discoverers. It's so massive that when initially discovered, astronomers mistook it for a dwarf planet.

Interplanetary comets may not be that rare after all

Interplanetary comets may not be that rare after all

One of the most interesting discoveries in astronomy happened in 2019 when an interstellar comet was discovered in our solar system. The comet was called Borisov, and astronomers believe interstellar comets like it may not be rare after all. Recently, scientists calculated that there may be more objects from outside of our solar system in the Oort Cloud than objects born inside our solar system.

Comet Atlas may have passed through our solar system before

Comet Atlas may have passed through our solar system before

Astronomers first noticed a comet called Atlas (C/2019 Y4) at the beginning of 2020. It was first detected by the Asteroid Terrestrial-impact Last Alert System (ATLAS) operated by the University of Hawaii. The asteroid was detected in mid-2020 as the main comet disintegrated into smaller pieces of ice.

LCO astronomers say comet C/2014 UN271 is the largest ever discovered

A new comet was discovered last month by astronomers called Comet C/2014 UN271 Bernardinelli-Bernstein. The image below is a synthetic color composite image made using the Las Cumbres Observatory (LCO) one-meter telescope located in Sutherland, South Africa. The image was taken on June 22, 2021, and the comet is in roughly the center of the image with a hazy and diffuse cloud around it.

Study reveals secrets of comet 46P/Wirtanen

In 2018, comet 46P/Wirtanen made its closest approach to Earth on December 16, 2018. Due to the proximity to the holidays, the comet was nicknamed the "Christmas Comet" and exuded an interesting green glow. It passed 7.1 million miles from Earth which is the closest pass it had made to the Earth in centuries.

A mysterious comet is entering our solar system for the first time

Every now and then, astronomers discover something in the cosmos that has never been seen before. Such was the case recently when scientists discovered a new object which has only recently been confirmed to be a comet. The new comet is called Bernardinelli-Bernstein, and astronomers investigating the object have determined it has an orbit that takes 5.5 million years to complete.

Astronomers discover heavy metal vapor inside comets

Astronomers discover heavy metal vapor inside comets

The team of researchers from Belgium have used data gathered by the European Southern Observatories Very Large Telescope and discovered that iron and nickel exist in the atmosphere of comets distributed throughout the solar system. The researchers say the same metal vapors are also found in comets that are very far from the sun. Another team of researchers from Poland also used data from the ESO and found that nickel vapor is present in the icy interstellar comet 2I/Borisov.

Comet 2l/Borisov is one of the most pristine comets ever observed

The European Southern Observatory Very Large Telescope has performed new observations of comet 2l/Borisov. It's only the second interstellar visitor ever detected in our Solar System. The ESO's observations have also indicated that 2l/Borisov is one of the most pristine comets ever observed.

Mysterious interstellar object ‘Oumuamua was likely part of a Pluto-like planet

Mysterious interstellar object ‘Oumuamua was likely part of a Pluto-like planet

Researchers from Arizona State University have been looking into the origins of the interstellar object called 'Oumuamua discovered in 2017. 'Oumuamua has become quite famous because it was the first interstellar object from beyond our solar system discovered using the Pan-STARRS astronomical Observatory in Hawaii. The word "'Oumuamua" means scout or messenger in Hawaiian.

NASA says comets could have delivered carbon to rocky planets

In 2016 a comet flew past the Earth known as Comet Catalina. The comet was briefly visible to astronomers on Earth before it flew past the sun and disappeared out of the solar system. While Catalina was visible, multiple observatories on Earth captured data and images to study.

Harvard researchers have a new theory on what killed the dinosaurs

Harvard researchers have a new theory on what killed the dinosaurs

Scientists know that about 66 million years ago, a major event happened on earth that resulted in the extinction of the dinosaurs. The Chicxulub impactor, as the impact is known, left behind a massive crater off the coast of Mexico 93 miles wide and 12 miles deep. While scientists know this is the impact that made many species on Earth at the time go extinct, there is debate about exactly what the Chicxulub impactor was and where it came from.
