The American Aeronautics and Space Agency (NASA) has released a panorama created from photographs of the space section (Northern Sky) seen from the Northern Hemisphere, taken by the Transitional Other Planet Research Satellite (TESS).

In the statement made by the American Aeronautics and Space Agency (NASA), it was stated that the panorama that divides the 180-degree slice of space into 13 sectors was created by combining 208 photographs taken by the Transitional Other Planet Research Satellite (TESS) in the second year of its exploration voyage.

TESS, launched into space on April 18, 2018 to detect the presence of planets in star systems outside the Solar System, discovered 21 exoplanets known as the “Southern Sky” in the first year of its mission, which has been confirmed in the part of space seen from the Southern Hemisphere. He also reached findings about the planet that await confirmation.

The Northern Sky panorama covers a more limited area than the Southern Sky panorama released last year.

To the left of the panorama photo completed in July 2020 , the Milky Way Galaxy stretches out in a radiant arc covered by dust clouds.

To the left of the Milky Way arc, 2.5 million light-years away, the Andromeda Galaxy is seen as an oval spot.

Containing 4 large camera equipment, each one observing a quarter of the space in the direction it is facing, continuously for 27 days, TESS was able to view approximately 75 percent of the Southern Sky in the first year of its exploration mission and 50 percent of the Northern Sky in the second year.

Blind spots that the satellite cannot view are due to mission planners at NASA pointing the cameras further north and further south so that the light reflected from the Earth and Moon surface does not affect the optical lenses.

TESS satellite

The TESS satellite aims to discover exoplanets orbiting stars outside the Solar System.

The satellite tries to detect exoplanets in a location called “transition”.

“Transition” describes the moment when an exoplanet passes in front of a star orbiting it. By observing the decrease in the brightness of the star reflected on the cameras at this moment, scientists can determine the mass, density and atmosphere composition of the planets in question by measuring the emission and absorption of light.
