Bernardinelli -Bernstein is a well -known guilty of the Ort cloud, and its nucleus is at least 100 km, with estimates of up to 137 km, and this size exceeds Hallebob comet, known as about twice.
The cloud of Ort is a huge gathering of small ice bodies that surround the solar system like a huge shell, located at huge distances from the sun.
This cloud has not been monitored immediately before, but its presence is inferred through long-term comets, those whose course is more than two hundred years, and in the case of Bernardine-Bernstein, its orbit requires millions of years to make only one cycle around the sun.
Complex jets
The comet was first discovered in 2014 when it was far from the planet Neptune, and the guilty is very far from the solar system, but it is on its way to approach the sun until the distance of the orbit of Saturn, in January 2031.
Recently, the scientists noted that this comet began to launch the first and carbon dioxide in the form of complex and developed jets that change their shape over time, and this is the first time scientists note an activity of the guilty at these very distant distances in the coldest regions of the solar system, outside the giant planets.
This indicates, according to study Scientists have recently published it in the journal “The Strofizal Journal Litters” that the cold nucleus of comets can contain “ultra -freezing gases”, because they are the only vehicles that are launched even in extreme cold, while as it approaches the sun, the water is usually responsible for such jets, when it is freed due to heat.
This provides scientists to a direct look at chemistry on the outskirts of the solar system, as these are the first indications of the activity of guilty of this age and dimension, and the comet allows scientists to study how the origins and development of icy bodies without the effect of direct solar radiation.
Atakama matrix
Meteorology was held through the large Milemartine/Don Melmiterian matrix, located on the Chachnator Plateau in the Atacama Desert, north of Chile, at an altitude of more than 5,000 meters above sea level.
The matrix is not a single telescope, but rather a group of 66 air -to -air (radio observatory), the dishes are connected together using a technique called “interference measurement”, which makes it work as one device with terrible precision.
Scientists can move dishes and change their distribution to increase or reduce accuracy as needed, such as rounding or removing the lens, in the case of light telescopes.
This matrix works in lengths of a taller wave of infrared, and shorter than radio waves, i.e. in the “millimeter and at a millimeter” range of wavelength.
These domains are used to monitor very cold objects in the universe, such as molecular clouds, comets and planetary tablets.
