New Zealand records first symptoms

Astronomers New Zealand Took advantage of the time zone: they first detected the first signs of activity Kite The registration size is C / 2014 UN271, also known as Bernardinelli-Bernstein.

They were able to observe and record the coma or atmosphere of gas and dust orbiting around the megacomte, which is a thousand times larger than a typical comet. What’s more, it may be the largest comet ever seen in history.

On June 23 the Greenwich Mean Time was recorded at 4:00 am, and in New Zealand it was already 5:00 pm. The images captured by the Los Combres Laboratory (LCO) are distributed around the world by a monitoring team, and the images are captured by an LCO telescope housed in the Astronomical Laboratory. South Africa.

“The others were asleep,” recalled Michael Bunnister, a member of the LCO team at the University of Canterbury in New Zealand, in a statement released this Wednesday (14).

However, at first, Bunnister thought the new films would fail, thanks to the problem that always exists Satellites Passing through the field of view of telescopes.

“The first image obscured the comet by a satellite path, and I was disappointed,” he revealed. “But the others were clear enough, and certainly a nice blur without being as sharp as the neighboring stars,” the astronomer celebrates.

What caught his attention was seeing a huge coma emerge at an incredible distance from the sun. Bernardinelli-Bernstein had about 19 astronomical units (AU) from the sun when photographed. (An AU is the average distance from the Earth to the Sun, about 150 million kilometers). This is almost twice the distance between Saturn and our star.

That comet has a lot of mass to warm up. The Bernardinelli-Bernstein nucleus is estimated to be over 100 km in diameter, three times larger than the next largest comet: Hale-pop, a famous naked-eyed comet past Earth. In 1998.

However, unfortunately for interested astronomers, Bernardinelli-Bernstein will not come very close to our planet. Megacomat’s closest approach to the Sun will be beyond Saturn in January 2031.
